drm/simpledrm: Add support for multiple "power-domains"

2023-09-25T08:53:47Z

Multiple power domains need to be handled explicitly in each driver. The driver core can not handle it automatically since it is not aware of power sequencing requirements the hardware might have. This is not a problem for simpledrm since everything is expected to be powered on by the bootloader. simpledrm has just ensure it remains powered on during its lifetime. This is required on Apple silicon M2 and M2 Pro/Max/Ultra desktop systems. The HDMI output initialized by the bootloader requires keeping the display controller and a DP phy power domain on.

drm: Call drm_atomic_helper_shutdown() at shutdown time for misc drivers

2023-09-21T17:41:04Z

Based on grepping through the source code these drivers appear to be missing a call to drm_atomic_helper_shutdown() at system shutdown time. Among other things, this means that if a panel is in use that it won't be cleanly powered off at system shutdown time. The fact that we should call drm_atomic_helper_shutdown() in the case of OS shutdown/restart comes straight out of the kernel doc "driver instance overview" in drm_drv.c. All of the drivers in this patch were fairly straightforward to fix since they already had a call to drm_atomic_helper_shutdown() at remove/unbind time but were just lacking one at system shutdown. The only hitch is that some of these drivers use the component model to register/unregister their DRM devices. The shutdown callback is part of the original device. The typical solution here, based on how other DRM drivers do this, is to keep track of whether the device is bound based on drvdata. In most cases the drvdata is the drm_device, so we can just make sure it is NULL when the device is not bound. In some drivers, this required minor code changes. To make things simpler, drm_atomic_helper_shutdown() has been modified to consider a NULL drm_device as a noop in the patch ("drm/atomic-helper: drm_atomic_helper_shutdown(NULL) should be a noop").

drm: gm12u320: Fix the timeout usage for usb_bulk_msg()

2023-09-04T08:00:57Z

The timeout arg of usb_bulk_msg() is ms already, which has been converted to jiffies by msecs_to_jiffies() in usb_start_wait_urb(). So fix the usage by removing the redundant msecs_to_jiffies() in the macros. And as Hans suggested, also remove msecs_to_jiffies() for the IDLE_TIMEOUT macro to make it consistent here and so change IDLE_TIMEOUT to msecs_to_jiffies(IDLE_TIMEOUT) where it is used.
