2023-08-31Merge tag 'clk-for-linus' of ↵Linus Torvalds1-16/+1
git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux 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 - Add missing GDSCs to and correct GDSCs for the SC8280XP global 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 - Correct Qualcomm SM6350 GPU clock controller's clock supplies - Drop unwanted clocks from the Qualcomm IPQ5332 GCC driver - 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 - Add the PDM IPC clock for i.MX93 - Add 519.75MHz frequency support for i.MX9 PLL - Simplify the .determine_rate() implementation for i.MX GPR mux - Make the i.MX8QXP LPCG clock use devm_platform_ioremap_resource() - Add the audio mux clock to i.MX8 - Fix the SPLL2 MULT range for PLLv4 - Update the SPLL2 type in i.MX8ULP - Fix the SAI4 clock on i.MX8MP - Add silicon revision print for i.MX25 on clocks init - Drop the return value from __mx25_clocks_init() - Fix the clock pauses on no-op set_rate for i.MX8M composite clock - Drop restrictions for i.MX PLL14xx and fix its max prediv value - Drop the 393216000 and 361267200 from i.MX PLL14xx rate table to allow glitch free switching" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (207 commits) clk: qcom: Fix SM_GPUCC_8450 dependencies clk: lmk04832: Support using PLL1_LD as SPI readback pin clk: lmk04832: Don't disable vco clock on probe fail clk: lmk04832: Set missing parent_names for output clocks clk: mvebu: Convert to devm_platform_ioremap_resource() clk: nuvoton: Convert to devm_platform_ioremap_resource() clk: socfpga: agilex: Convert to devm_platform_ioremap_resource() clk: ti: Use devm_platform_get_and_ioremap_resource() clk: mediatek: Convert to devm_platform_ioremap_resource() clk: hsdk-pll: Convert to devm_platform_ioremap_resource() clk: gemini: Convert to devm_platform_ioremap_resource() clk: fsl-sai: Convert to devm_platform_ioremap_resource() clk: bm1880: Convert to devm_platform_ioremap_resource() clk: axm5516: Convert to devm_platform_ioremap_resource() clk: actions: Convert to devm_platform_ioremap_resource() clk: cdce925: Remove redundant of_match_ptr() clk: pxa910: Move number of clocks to driver source clk: pxa1928: Move number of clocks to driver source clk: pxa168: Move number of clocks to driver source clk: mmp2: Move number of clocks to driver source ...

2023-08-14soc: qcom: aoss: Move length requirements from callerBjorn Andersson1-13/+12
The existing implementation of qmp_send() requires the caller to provide a buffer which is of word-aligned. The underlying reason for this is that message ram only supports word accesses, but pushing this requirement onto the clients results in the same boiler plate code sprinkled in every call site. By using a temporary buffer in qmp_send() we can hide the underlying hardware limitations from the clients and allow them to pass their NUL-terminates C string directly.

The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

2023-07-14soc: qcom: Add RPM processor/subsystem driverStephan Gerhold3-1/+79
Add a simple driver for the qcom,rpm-proc compatible that registers the "smd-edge" and populates other children defined in the device tree. Note that the DT schema belongs to the remoteproc subsystem while this driver is added inside soc/qcom. I argue that the RPM *is* a remoteproc, but as an implementation detail in Linux it can currently not benefit from anything provided by the remoteproc subsystem. The RPM firmware is usually already loaded and started by earlier components in the boot chain and is not meant to be ever restarted. To avoid breaking existing kernel configurations the driver is always built when smd-rpm.c is also built. They belong closely together anyway. To avoid build errors CONFIG_RPMSG_QCOM_SMD must be also built-in if rpm-proc is.

There is an ever growing list of compatibles in the smd-rpm.c driver. A fallback compatible would help here but would still require keeping the current list around for backwards compatibility. As an alternative, let's switch the driver to match the rpmsg_device_id instead, which is always "rpm_requests" on all platforms. Add a check to ensure that there is a device tree node defined for the device since otherwise the of_platform_populate() call will operate on the root node (/). Similar approaches with matching rpmsg_device_id are already used in qcom_sysmon, qcom_glink_ssr, qrtr, and rpmsg_wwan_ctrl.

The debugfs dump of Command DB relies uses %*pEp to print the resource identifiers, with escaping of non-printable characters. But p (ESCAPE_NP) does not escape NUL characters, so for identifiers less than 8 bytes in length the output will retain these. This does not cause an issue while looking at the dump in the terminal (no known complaints at least), but when programmatically consuming the debugfs output the extra characters are unwanted.

All of the data we need for that is already provided in the device tree, anyway. Change the thresholds to: * low = 0 (as we've been doing up until now) * med = high = BW_MIN Throughput going below the med threshold nudges bwmon into signaling that we should slow down (e.g. if we inherited too high bandwidth from the bootloader). Throughput going above the high threshold nudges bwmon into signaling that we should speed up so as not to choke the bus traffic due to insufficient transfer rates. F_MIN is a perfect initial value for both of these cases - if we go above it (and there's a 99.99% chance it'll happen at boot time), we should definitely make the memory go faster, whereas if we go below it, we should slow down, no matter what performance state we were at before (it's only possible for them to be >= FMIN). This only changes the values programmed at probe time, as high and med thresholds are updated at interrupt, also based on the OPP table from DT.

secondary sequencer The select_fifo/dma_mode() functions in geni driver enable/disable interrupts (secondary included) conditionally for non-uart modes, while uart is supposed to manage this internally. However, only uart uses secondary IRQs while spi, i2c do not care about these at all making their enablement (or disablement) totally unnecessary for these protos. Similarly, select_gpi_mode() also does disable s_irq and its useless again. Drop enabling/disabling secondary IRQs. This doesn't solve any observed problem but only gets rid of code pieces that are not required.

The enhanced detection introduced in commit '210d12c8197a ("soc: qcom: mdt_loader: Enhance split binary detection")' requires that all segments lies within the file on disk. But the Qualcomm firmware files consistently has a BSS-like segment at the end, with a p_offset aligned to the next 4k boundary. As the p_size is 0 and there's nothing to load, the image is not padded to cover this (empty) segment. Ignore zero-sized segments when determining if the image is split, to avoid this problem.

Commit ebeb20a9cd3f ("soc: qcom: mdt_loader: Always invoke PAS mem_setup") dropped the relocate check and made pas_mem_setup run unconditionally. The code was later moved with commit f4e526ff7e38 ("soc: qcom: mdt_loader: Extract PAS operations") to qcom_mdt_pas_init() effectively losing track of what was actually done. The assumption that PAS mem_setup can be done anytime was effectively wrong, with no good reason and this caused regression on some SoC that use remoteproc to bringup ath11k. One example is IPQ8074 SoC that effectively broke resulting in remoteproc silently die and ath11k not working. On this SoC FW relocate is not enabled and PAS mem_setup was correctly skipped in previous kernel version resulting in correct bringup and function of remoteproc and ath11k. To fix the regression, reintroduce the relocate check in qcom_mdt_pas_init() and correctly skip PAS mem_setup where relocate is not enabled.
