2022-12-12drm: atmel-hlcdc: Remove #ifdef guards for PM related functionsPaul Cercueil1-5/+4
Use the DEFINE_SIMPLE_DEV_PM_OPS() and pm_sleep_ptr() macros to handle the .suspend/.resume callbacks. These macros allow the suspend and resume functions to be automatically dropped by the compiler when CONFIG_SUSPEND is disabled, without having to use #ifdef guards. This has the advantage of always compiling these functions in, independently of any Kconfig option. Thanks to that, bugs and other regressions are subsequently easier to catch.

2022-12-08drm/bridge: Introduce pre_enable_prev_first to alter bridge init orderDave Stevenson1-24/+121
DSI sink devices typically want the DSI host powered up and configured before they are powered up. pre_enable is the place this would normally happen, but they are called in reverse order from panel/connector towards the encoder, which is the "wrong" order. Add a new flag pre_enable_prev_first that any bridge can set to swap the order of pre_enable (and post_disable) for that and the immediately previous bridge. Should the immediately previous bridge also set the pre_enable_prev_first flag, the previous bridge to that will be called before either of those which requested pre_enable_prev_first. eg: - Panel - Bridge 1 - Bridge 2 pre_enable_prev_first - Bridge 3 - Bridge 4 pre_enable_prev_first - Bridge 5 pre_enable_prev_first - Bridge 6 - Encoder Would result in pre_enable's being called as Panel, Bridge 1, Bridge 3, Bridge 2, Bridge 6, Bridge 5, Bridge 4, Encoder.

2022-12-08drm/tests: helpers: Switch to a platform_deviceMaxime Ripard1-2/+14
The device managed resources are ran if the device has bus, which is not the case of a root_device. Let's use a platform_device instead.

2022-12-08drm/tests: helpers: Create the device in another functionMaxime Ripard4-26/+73
We'll need in some tests to control when the device needs to be added and removed, so let's split the device creation from the DRM device creation function.

2022-12-08drm/tests: helpers: Rename the device init helperMaxime Ripard4-7/+12
The name doesn't really fit the conventions for the other helpers in DRM/KMS, so let's rename it to make it obvious that we allocate a new DRM device.

2022-12-08drm/tests: helpers: Switch to EXPORT_SYMBOL_GPLMaxime Ripard1-1/+1
drm_kunit_device_init() among other things will allocate a device and wrap around root_device_register. This function is exported with EXPORT_SYMBOL_GPL, so we can't really change the license.
