2023-06-20platform/x86: int3472: discrete: Add support for 1 GPIO regulator shared ↵Hans de Goede
between 2 sensors On the Lenovo Miix 510-12IKB there is 1 GPIO regulator, with its GPIO listed in the INT3472 device belonging to the OV5648 back sensor. But this regulator also needs to be enabled for the OV2680 front sensor to work. Add support to skl_int3472_register_regulator() to add supply map entries pointing to both sensors based on a DMI quirk table which gives the dev_name part of the supply map for the second sensor (the sensor without the GPIO listed in its matching INT3472 ACPI device).

2023-06-20platform/x86: int3472: discrete: Remove sensor_config-sHans de Goede
Currently the only 2 sensor_config-s both specify "avdd" as supply-id. The INT3472 device is going to be the only supplier of a regulator for the sensor device. So there is no chance of collisions with other regulator suppliers and it is undesirable to need to manually add new entries to int3472_sensor_configs[] for each new sensor module which uses a GPIO regulator. Instead just always use "avdd" as supply-id when registering the GPIO regulator. If necessary for specific sensor drivers then other supply-ids can be added as aliases in the future, adding aliases will be safe since INT3472 will be the only regulator supplier for the sensor.

2023-06-20platform/x86: int3472: discrete: Drop GPIO remapping supportHans de Goede
The only sensor driver which needs GPIO remapping support is the ov2680 driver and ACPI enumeration support + other necessary changes to the ov2680 driver were never upstreamed. A new series updating the ov2680 driver is pending upstream now and in this series the ov2680 driver is patched to look for "powerdown" as con-id, instead of relying on GPIO remapping in the int3472 code, so the GPIO remapping is no longer necessary.

Sparce doesn't seem to like using be32_to_cpu and cpu_to_be32 to convert values for the MMIO gmux to/from the host architecture. Instead use iowrite32be and ioread32be to always convert, which should be fine because apple-gmux is only used on x86 with is always little endian.

Currently rbtn_add() in case of failure is leaking resources. Fix this by adding a proper rollback. Move devm_kzalloc() before rbtn_acquire(), so it doesn't require rollback in case of failure.

2023-05-30platform/surface: aggregator: Allow completion work-items to be executed in ↵Maximilian Luz
parallel Currently, event completion work-items are restricted to be run strictly in non-parallel fashion by the respective workqueue. However, this has lead to some problems: In some instances, the event notifier function called inside this completion workqueue takes a non-negligible amount of time to execute. One such example is the battery event handling code (surface_battery.c), which can result in a full battery information refresh, involving further synchronous communication with the EC inside the event handler. This is made worse if the communication fails spuriously, generally incurring a multi-second timeout. Since the event completions are run strictly non-parallel, this blocks other events from being propagated to the respective subsystems. This becomes especially noticeable for keyboard and touchpad input, which also funnel their events through this system. Here, users have reported occasional multi-second "freezes". Note, however, that the event handling system was never intended to run purely sequentially. Instead, we have one work struct per EC/SAM subsystem, processing the event queue for that subsystem. These work structs were intended to run in parallel, allowing sequential processing of work items for each subsystem but parallel processing of work items across subsystems. The only restriction to this is the way the workqueue is created. Therefore, replace create_workqueue() with alloc_workqueue() and do not restrict the maximum number of parallel work items to be executed on that queue, resolving any cross-subsystem blockage.
