git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into arm/drivers ARM SCMI updates for v5.13 The major and big addition this time is to support modularisation of individual SCMI protocols thus enabling to add support for vendors' custom SCMI protocol. This changes the interface provided by the SCMI driver to all the users of SCMI and hence involved changes in various other subsystem SCMI drivers. The change has been split with a bit of transient code to preserve bisectability and avoiding one big patch bomb changing all the users. This also includes SCMI IIO driver(pulled from IIO tree) and support for per-cpu DVFS. * tag 'scmi-updates-5.13' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux: (41 commits) firmware: arm_scmi: Add dynamic scmi devices creation firmware: arm_scmi: Add protocol modularization support firmware: arm_scmi: Rename non devres notify_ops firmware: arm_scmi: Make notify_priv really private firmware: arm_scmi: Cleanup events registration transient code firmware: arm_scmi: Cleanup unused core transfer helper wrappers firmware: arm_scmi: Cleanup legacy protocol init code firmware: arm_scmi: Make references to handle const firmware: arm_scmi: Remove legacy scmi_voltage_ops protocol interface regulator: scmi: Port driver to the new scmi_voltage_proto_ops interface firmware: arm_scmi: Port voltage protocol to new protocols interface firmware: arm_scmi: Port systempower protocol to new protocols interface firmware: arm_scmi: Remove legacy scmi_sensor_ops protocol interface iio/scmi: Port driver to the new scmi_sensor_proto_ops interface hwmon: (scmi) port driver to the new scmi_sensor_proto_ops interface firmware: arm_scmi: Port sensor protocol to new protocols interface firmware: arm_scmi: Remove legacy scmi_reset_ops protocol interface reset: reset-scmi: Port driver to the new scmi_reset_proto_ops interface firmware: arm_scmi: Port reset protocol to new protocols interface firmware: arm_scmi: Remove legacy scmi_clk_ops protocol interface ...

2021-04-08iommu/amd: Page-specific invalidations for more than one pageNadav Amit1-34/+42
Currently, IOMMU invalidations and device-IOTLB invalidations using AMD IOMMU fall back to full address-space invalidation if more than a single page need to be flushed. Full flushes are especially inefficient when the IOMMU is virtualized by a hypervisor, since it requires the hypervisor to synchronize the entire address-space. AMD IOMMUs allow to provide a mask to perform page-specific invalidations for multiple pages that match the address. The mask is encoded as part of the address, and the first zero bit in the address (in bits [51:12]) indicates the mask size. Use this hardware feature to perform selective IOMMU and IOTLB flushes. Combine the logic between both for better code reuse. The IOMMU invalidations passed a smoke-test. The device IOTLB invalidations are untested.

2021-04-08clocksource/drivers/timer-ti-dm: Handle dra7 timer wrap errata i940Tony Lindgren1-0/+76
There is a timer wrap issue on dra7 for the ARM architected timer. In a typical clock configuration the timer fails to wrap after 388 days. To work around the issue, we need to use timer-ti-dm percpu timers instead. Let's configure dmtimer3 and 4 as percpu timers by default, and warn about the issue if the dtb is not configured properly. Let's do this as a single patch so it can be backported to v5.8 and later kernels easily. Note that this patch depends on earlier timer-ti-dm systimer posted mode fixes, and a preparatory clockevent patch "clocksource/drivers/timer-ti-dm: Prepare to handle dra7 timer wrap issue". For more information, please see the errata for "AM572x Sitara Processors Silicon Revisions 1.1, 2.0": https://www.ti.com/lit/er/sprz429m/sprz429m.pdf The concept is based on earlier reference patches done by Tero Kristo and Keerthy.

s3c_adc_bat_remove() This driver's remove path calls cancel_delayed_work(). However, that function does not wait until the work function finishes. This means that the callback function may still be running after the driver's remove function has finished, which would result in a use-after-free. Fix by calling cancel_delayed_work_sync(), which ensures that the work is properly cancelled, no longer running, and unable to re-schedule itself.

2021-04-08power: supply: Add AC driver for Surface Aggregator ModuleMaximilian Luz3-0/+299
On newer Microsoft Surface models (specifically 7th-generation, i.e. Surface Pro 7, Surface Book 3, Surface Laptop 3, and Surface Laptop Go), battery and AC status/information is no longer handled via standard ACPI devices, but instead directly via the Surface System Aggregator Module (SSAM), i.e. the embedded controller on those devices. While on previous generation models, AC status is also handled via SSAM, an ACPI shim was present to translate the standard ACPI AC interface to SSAM requests. The SSAM interface itself, which is modeled closely after the ACPI interface, has not changed. This commit introduces a new SSAM client device driver to support AC status/information via the aforementioned interface on said Surface models.

2021-04-08clocksource/drivers/timer-ti-dm: Add missing set_state_oneshot_stoppedTony Lindgren1-0/+1
To avoid spurious timer interrupts when KTIME_MAX is used, we need to configure set_state_oneshot_stopped(). Although implementing this is optional, it still affects things like power management for the extra timer interrupt. For more information, please see commit 8fff52fd5093 ("clockevents: Introduce CLOCK_EVT_STATE_ONESHOT_STOPPED state") and commit cf8c5009ee37 ("clockevents/drivers/arm_arch_timer: Implement ->set_state_oneshot_stopped()").

2021-04-08clocksource/drivers/timer-ti-dm: Fix posted mode status check orderTony Lindgren1-6/+6
When the timer is configured in posted mode, we need to check the write- posted status register (TWPS) before writing to the register. We now check TWPS after the write starting with commit 52762fbd1c47 ("clocksource/drivers/timer-ti-dm: Add clockevent and clocksource support"). For example, in the TRM for am571x the following is documented in chapter "22.2.4.13.1.1 Write Posting Synchronization Mode": "For each register, a status bit is provided in the timer write-posted status (TWPS) register. In this mode, it is mandatory that software check this status bit before any write access. If a write is attempted to a register with a previous access pending, the previous access is discarded without notice." The regression happened when I updated the code to use standard read/write accessors for the driver instead of using __omap_dm_timer_load_start(). We have__omap_dm_timer_load_start() check the TWPS status correctly using __omap_dm_timer_write().
