[PATCH v2 00/21] drm/tilcdc: Atomic modeset support

[Jyri Sarha <jsarha@ti.com>]

This series implements atomic modeset for TI's LCDC HW. The code has
been tested on X-server, weston, and our kmsxx kms testing suite. The
patches are based on my earlier tilcdc fixes and cleanups series [1].

I know that the tiny display pipe has been accepted for mainline and I
have intention of moving lcdc on top of it at some point. However,
there is just too many things I would still have to reimplemet to do
it now. How to deal with different encoders, connectors and panels
for example. This series should be considered as a first step towards
making that move. It implements many things that are needed in simple
display pipe too.

There is a lot of changes since RFC version of the series and this is
not a complete list:

- Added patches
 - drm/tilcdc: Fix tilcdc component master unloading
 - drm/tilcdc: Make tilcdc_crtc_page_flip() work if crtc is not yet on
 - drm/tilcdc: panel: Set crtc panel info at init phase
 - drm/tilcdc: panel: Add atomic modeset helpers to connector funcs
 - drm/tilcdc: tfp410: Set crtc panel info at init phase
 - drm/tilcdc: tfp410: Add atomic modeset helpers to connector funcs
 - drm/tilcdc: Enable and disable interrupts in crtc start() and stop()
 - drm/tilcdc: Use drm_atomic_helper_resume/suspend()
 - drm/tilcdc: Get rid of legacy dpms mechanism
 - drm/tilcdc: Remove unnecessary pm_runtime_get() and *_put() calls
 - drm/tilcdc: Change tilcdc_crtc_page_flip() to tilcdc_crtc_update_fb()
- At least following changes to the "old" patches
 - Add mechanism to update crtc state's mode_changed if plane fb
   pixel_format changes
 - Add tilcdc_atomic_check() for mode_config_funcs
 - Leave tilcdc_crtc_mode_fixup() connected to drm_crtc_helper_funcs
