Pull clk updates from Stephen Boyd:
"I'm actually surprised this time. There aren't any new Qualcomm SoC
clk drivers. And there's zero diff in the core clk framework.
Instead we have new clk drivers for STM and Sophgo, with
Samsung^WGoogle in third for the diffstat because they introduced HSI0
and HSI2 clk drivers for Google's GS101 SoC (high speed interface
things like PCIe, UFS, and MMC).
Beyond those big diffs there's the usual updates to various clk
drivers for incorrect parent descriptions or mising
MODULE_DEVICE_TABLE()s, etc. Nothing in particular stands out as super
interesting here.
New Drivers:
- STM32MP257 SoC clk driver
- Airoha EN7581 SoC clk driver
- Sophgo CV1800B, CV1812H and SG2000 SoC clk driver
- Loongson-2k0500 and Loongson-2k2000 SoC clk driver
- Add HSI0 and HSI2 clock controllers for Google GS101
- Add i.MX95 BLK CTL clock driver
Updates:
- Allocate clk_ops dynamically for SCMI clk driver
- Add support in qcom RCG and RCG2 for multiple configurations for
the same frequency

Pull trusted keys updates from Jarkko Sakkinen:
"This contains a new key type for the Data Co-Processor (DCP), which is
an IP core built into many NXP SoCs such as i.mx6ull"
* tag 'keys-trusted-next-6.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jarkko/linux-tpmdd:
docs: trusted-encrypted: add DCP as new trust source
docs: document DCP-backed trusted keys kernel params
MAINTAINERS: add entry for DCP-based trusted keys
KEYS: trusted: Introduce NXP DCP-backed trusted keys
KEYS: trusted: improve scalability of trust source config
crypto: mxs-dcp: Add support for hardware-bound keys
|
|
DCP (Data Co-Processor) is able to derive private keys for a fused
random seed, which can be referenced by handle but not accessed by
the CPU. Similarly, DCP is able to store arbitrary keys in four
dedicated key slots located in its secure memory area (internal SRAM).
These keys can be used to perform AES encryption.
Expose these derived keys and key slots through the crypto API via their
handle. The main purpose is to add DCP-backed trusted keys. Other
use cases are possible too (see similar existing paes implementations),
but these should carefully be evaluated as e.g. enabling AF_ALG will
give userspace full access to use keys. In scenarios with untrustworthy
userspace, this will enable en-/decryption oracles.

While moving all the reset code in the PolarFire SoC clock driver to the
reset subsystem, I removed an `#if IS_ENABLED(RESET_CONTROLLER)` from
the driver and moved it to the header, however this was not the correct
thing to do. In the driver such a condition over-eagerly provided a
complete implementation for mpfs_reset_{read,write}() when the reset
subsystem was enabled without the PolarFire SoC reset driver, but in the
header it meant that when the subsystem was enabled and the driver was
not, no implementation for mpfs_reset_controller_register() was
provided. Fix the condition so that the stub implementation of
mpfs_reset_controller_register() is used when the reset driver is
disabled.

Each RPMh VRM accelerator resource has 3 or 4 contiguous 4-byte aligned
addresses associated with it. These control voltage, enable state, mode,
and in legacy targets, voltage headroom. The current in-flight request
checking logic looks for exact address matches. Requests for different
addresses of the same RPMh resource as thus not detected as in-flight.
Add new cmd-db API cmd_db_match_resource_addr() to enhance the in-flight
request check for VRM requests by ignoring the address offset.
This ensures that only one request is allowed to be in-flight for a given
VRM resource. This is needed to avoid scenarios where request commands are
carried out by RPMh hardware out-of-order leading to LDO regulator
over-current protection triggering.

Qualcomm driver updates for v6.9
This introduces the Qualcomm Programmable Boot Sequencer (PBS) driver.
The Qualcomm SMEM no longer acquires the hwspinlock during the "get"
operation, to improve the system behavior during the recovery of a
remoteproc that crashed with the hwspinlock held.
The Qualcomm Always On Subsystem (AOSS) message protocol driver gains
tracepoints, printf annotation, and a debugfs interface is introduced
for tweaking system properties during development and debugging.
The Qualcomm socinfo driver gains data for SM8475, QCM8550 and
QCS8550 platforms, and the PM2250 is renamed to PM4125.
Support for controlling the voltage regulator in SPM/SAW2 is introduced.
The gfx.lvl power-domain is dropped for SA8540P, as this resource was
incorrectly inherited from SC8280XP.
Additionally some code cleanup improvements is introduced across APR,
LLCC, SMP2P and SPM.

RISC-V SoC drivers for v6.8
There's only one set of changes here, the addition of "Auto Update"
support for PolarFire SoC. Auto Update is one of the ways that the FPGA
bitstream can be updated, and the only one suitable for use from Linux
as it does not immediately initiate a reboot when started.
The driver was not accepted in the FPGA manager subsystem as the update
only occurs after a reboot and makes no use of the FPGA manager
framework.

In HDLC mode, some status flags related to the data read transfer can be
set by the hardware and need to be known by a QMC consumer for further

Extend the API in order to provide these transfer status flags at the

In TRANSPARENT mode, these flags have no meaning. Keep only one read
complete() API and update the consumers working in transparent mode.

For some devices the bootloader/firmware may set up the device in
bypass. Memory clients like display needs kernel to program SID after
resume because bootloader/firmware programs the SID of display device to
bypass. In order to make sure that kernel IOMMU mappings for these

memory clients on memory controller resume.

The DFI is a unit which is suitable for measuring DDR utilization, but
so far it could only be used as an event driver for the DDR frequency
scaling driver. This adds perf support to the DFI driver.
Usage with the 'perf' tool can look like:
perf stat -a -e rockchip_ddr/cycles/,\
rockchip_ddr/read-bytes/,\
rockchip_ddr/write-bytes/,\
rockchip_ddr/bytes/ sleep 1
Performance counter stats for 'system wide':
1582524826 rockchip_ddr/cycles/
1802.25 MB rockchip_ddr/read-bytes/

3595.90 MB rockchip_ddr/bytes/
1.014369709 seconds time elapsed
perf support has been tested on a RK3568 and a RK3399, the latter with
dual channel DDR.

The DDRTYPE defines are named to be RK3399 specific, but they can be
used for other Rockchip SoCs as well, so replace the RK3399_PMUGRF_
prefix with ROCKCHIP_. They are defined in a SoC specific header
file, so when generalizing the prefix also move the new defines to
a SoC agnostic header file. While at it use GENMASK to define the
DDRTYPE bitfield and give it a name including the full register name.

Add suspend hook and a 'suspended' field in the 'struct tegra_bpmp'
to mark if BPMP is suspended. Also, add a 'flags' field in the
'struct tegra_bpmp_message' whose 'TEGRA_BPMP_MESSAGE_RESET' bit can be
set from the Tegra MC driver to signal that the reset of BPMP IPC
channels is required before sending MRQ to the BPMP FW. Together both
the fields allow us to handle any requests that might be sent too soon
as they can cause hang during system resume.
One case where we see BPMP requests being sent before the BPMP driver
has resumed is the memory bandwidth requests which are triggered by
onlining the CPUs during system resume. The CPUs are onlined before the
BPMP has resumed and we need to reset the BPMP IPC channels to handle
these requests.
The additional check for 'flags' is done to avoid any un-intended BPMP
IPC reset if the tegra_bpmp_transfer*() API gets called during suspend
sequence after the BPMP driver is suspended.

Thierry says this is not used anymore, and doesn't think it makes sense as
an iommu driver. The HW it supports is about 10 years old now and newer HW
uses different IOMMU drivers.
As this is the only driver with a GART approach, and it doesn't really
meet the driver expectations from the IOMMU core, let's just remove it
so we don't have to think about how to make it fit in.
It has a number of identified problems:
- The assignment of iommu_groups doesn't match the HW behavior
- It claims to have an UNMANAGED domain but it is really an IDENTITY
domain with a translation aperture. This is inconsistent with the core
expectation for security sensitive operations
- It doesn't implement a SW page table under struct iommu_domain so
* It can't accept a map until the domain is attached
* It forgets about all maps after the domain is detached
* It doesn't clear the HW of maps once the domain is detached
(made worse by having the wrong groups)

Pull clk subsystem updates from Stephen Boyd:
"This pull request is full of clk driver changes. In fact, there aren't
any changes to the clk framework this time around. That's probably
because everyone was on vacation (yours truly included). We did lose a
couple clk drivers this time around because nobody was using those
devices. That skews the diffstat a bit, but either way, nothing looks
out of the ordinary here. The usual suspects are chugging along adding
support for more SoCs and fixing bugs.
If I had to choose, I'd say the theme for the past few months has been
"polish". There's quite a few patches that migrate to
devm_platform_ioremap_resource() in here. And there's more than a
handful of patches that move the NR_CLKS define from the DT binding
header to the driver. There's even patches that migrate drivers to use
clk_parent_data and clk_hw to describe clk tree topology. It seems
that the spring (summer?) cleaning bug got some folks, or the
semiconductor shortage finally hit the software side.
New Drivers:
- StarFive JH7110 SoC clock drivers
- Qualcomm IPQ5018 Global Clock Controller driver
- Versa3 clk generator to support 48KHz playback/record with audio
codec on RZ/G2L SMARC EVK
Removed Drivers:
- Remove non-OF mmp clk drivers
- Remove OXNAS clk driver
Updates:
- Add __counted_by to struct clk_hw_onecell_data and struct
spmi_pmic_div_clk_cc
- Move defines for numbers of clks (NR_CLKS) from DT headers to
drivers
- Introduce kstrdup_and_replace() and use it
- Add PLL rates for Rockchip rk3568
- Add the display clock tree for Rockchip rv1126
- Add Audio Clock Generator (ADG) clocks on Renesas R-Car Gen3 and
RZ/G2 SoCs
- Convert sun9i-mmc clock to use
devm_platform_get_and_ioremap_resource()
- Fix function name in a comment in ccu_mmc_timing.c
- Parameter name correction for ccu_nkm_round_rate()
- Implement CLK_SET_RATE_PARENT for Allwinner NKM clocks, i.e.
consider alternative parent rates when determining clock rates
- Set CLK_SET_RATE_PARENT for Allwinner A64 pll-mipi
- Support finding closest (as opposed to closest but not higher)
clock rate for NM, NKM, mux and div type clocks, as use it for
Allwinner A64 pll-video0
- Prefer current parent rate if able to generate ideal clock rate for
Allwinner NKM clocks
- Clean up Qualcomm SMD RPM driver, with interconnect bus clocks
moved out to the interconnect drivers
- Fix various PM runtime bugs across many Qualcomm clk drivers
- Migrate Qualcomm MDM9615 is to parent_hw and parent_data
- Add network related resets on Qualcomm IPQ4019
- Add a couple missing USB related clocks to Qualcomm IPQ9574
- Add missing gpll0_sleep_clk_src to Qualcomm MSM8917 global clock
controller
- In the Qualcomm QDU1000 global clock controller, GDSCs, clkrefs,
and GPLL1 are added, while PCIe pipe clock, SDCC rcg ops are
corrected

clock controller driver
- Support retention for the Qualcomm SC8280XP display clock
controller GDSCs.
- Qualcommm's SDCC apps_clk_src is marked with CLK_OPS_PARENT_ENABLE
to fix issues with missing parent clocks across sc7180, sm7150,
sm6350 and sm8250, while sm8450 is corrected to use floor ops

- Add missing OXILICX GDSC to Qualcomm MSM8226 GCC
- Change the delay in the Qualcomm reset controller to fsleep() for
correctness
- Extend the Qualcomm SM83550 Video clock controller to support
SC8280XP
- Add graphics clock support on Renesas RZ/G2M, RZ/G2N, RZ/G2E, and
R-Car H3, M3-W, and M3-N SoCs
- Add Clocked Serial Interface (CSI) clocks on Renesas RZ/V2M
- Add PWM (MTU3) clock and reset on Renesas RZ/G2UL and RZ/Five

Memory controller drivers - fixes for v6.5
Two fixes are needed for Tegra194 memory controllers caused by the same
Tegra PCI commit merged in v6.5-rc1. The Tegra PCI requires now
interconnect from the memory controller, which was set only for
Tegra234, but not for Tegra194, causing probe deferrals. Expose some
dummy interconnect provider for Tegra194, to satisfy PCI driver needs.

With the introduction of commit 9365bf006f53 ("PCI: tegra194: Add
interconnect support in Tegra234"), the PCI driver on Tegra194 and later
requires an interconnect provider. However, a provider is currently only
exposed on Tegra234 and this causes PCI on Tegra194 to defer probe
indefinitely.
Fix this by adding a dummy implementation on Tegra194. This allows nodes
to be provided to interconnect consumers, but doesn't do any bandwidth
accounting or frequency scaling.

In a future change we will need to make
ocelot_port_update_active_preemptible_tcs() call
vsc9959_tas_guard_bands_update(), but that is currently not possible,
since the ocelot switch lib does not have access to functions private to
the DSA wrapper.
Move the pointer to vsc9959_tas_guard_bands_update() from felix->info
(which is private to the DSA driver) to ocelot->ops (which is also
visible to the ocelot switch lib).

In a future commit we will have to call vsc9959_tas_guard_bands_update()
from ocelot_port_update_active_preemptible_tcs(), and that will be
impossible due to the AB/BA locking dependencies between
ocelot->tas_lock and ocelot->fwd_domain_lock.
Just like we did in commit 3ff468ef987e ("net: mscc: ocelot: remove
struct ocelot_mm_state :: lock"), the only solution is to expand the
scope of ocelot->fwd_domain_lock for it to also serialize changes made
to the Time-Aware Shaper, because those will have to result in a
recalculation of cut-through TCs, which is something that depends on the
forwarding domain.

In a future change, the driver will need to determine whether PTP RX
timestamping is enabled on a port (including whether traps were set up
on that port in particular) and that is currently not possible.
The driver supports different RX filters (L2, L4) and kinds of TX
timestamping (one-step, two-step) on its ports, but it saves all
configuration in a single struct hwtstamp_config that is global to the
switch. So, the latest timestamping configuration on one port
(including a request to disable timestamping) affects what gets reported
for all ports, even though the configuration itself is still individual
to each port.
The port timestamping configurations are only coupled because of the
common structure, so replace the hwtstamp_config with a mask of trapped
protocols saved per port. We also have the ptp_cmd to distinguish
between one-step and two-step PTP timestamping, so with those 2 bits of
information we can fully reconstruct a descriptive struct
hwtstamp_config for each port, during the SIOCGHWTSTAMP ioctl.
