2022-12-15drm/vc4: dsi: Convert to using a bridge instead of encoderDave Stevenson1-31/+90
Remove the encoder functions, and create a bridge attached to this dumb encoder which implements the same functionality. As a bridge has state which an encoder doesn't, we need to add the state management functions as well. As there is no bridge atomic_mode_set, move the initialisation code that was in mode_set into _pre_enable. The code to actually enable and disable sending video are split from the general control into _enable and _disable.

2022-12-15drm/vc4: dsi: Convert to use atomic operationsDave Stevenson1-8/+15
The atomic calls are preferred as the non-atomic ones are deprecated. In preparation for conversion to a bridge, switch to the atomic calls. Signed-off-by: Dave Stevenson <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Maxime Ripard <[email protected]>
2022-12-15drm/vc4: dsi: Remove splitting the bridge chain from the driverDave Stevenson1-47/+0
Splitting the bridge chain fails for atomic bridges as the framework can't add the relevant state in drm_atomic_add_encoder_bridges. The chain was split because we needed to power up before calling pre_enable, but that is now done in mode_set, and will move into the framework.

2022-12-15drm/vc4: dsi: Move initialisation to encoder_mode_setDave Stevenson1-4/+12
Breaking the bridge chain does not work for atomic bridges/panels and generally causes issues. We need to initialise the DSI host before the bridge pre_enables are called, so move that to encoder_mode_set in the same way that dw-mipi-dsi does.

2022-12-15drm/vc4: dsi: Rename bridge to out_bridgeDave Stevenson1-6/+6
In preparation for converting the encoder to being a bridge, rename the variable holding the next bridge in the chain to out_bridge, so that our bridge can be called bridge.

2022-12-12drm: exynos: Remove #ifdef guards for PM related functionsPaul Cercueil9-75/+28
Use the DEFINE_RUNTIME_DEV_PM_OPS(), SYSTEM_SLEEP_PM_OPS(), RUNTIME_PM_OPS() and pm_ptr() macros to handle the runtime and suspend PM callbacks. These macros allow the suspend and resume functions to be automatically dropped by the compiler when CONFIG_PM 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.
