We can't use the drm_gem_reservation_object_wait() helper for MSM
because (in theory) msm_gem_cpu_prep() will also do some cache
maintenance on the GEM object.

Many users of drm_gem_object embed a struct reservation_object into
their subclassed struct, so let's add one to struct drm_gem_object.
This will allow removing the reservation object from the subclasses
and removing the ->gem_prime_res_obj callback.

With the addition, add a drm_gem_reservation_object_wait() helper
function for drivers to use in wait ioctls.

The Allwinner BSP makes sure that we don't end up with a null start delay
or with a delay larger than vtotal.

The former condition is likely to happen now with the reworked start delay,
so make sure we enforce the same boundaries.

The current calculation for the video start delay in the current DSI driver
is that it is the total vertical size, minus the front porch and sync length,
plus 1. This equals to the active vertical size plus the back porch plus 1.

That 1 is coming in the Allwinner BSP from an variable that is set to 1.
However, if we look at the Allwinner BSP more closely, and especially in
the "legacy" code for the display (in drivers/video/sunxi/legacy/), we can
see that this variable is actually computed from the porches and the sync
minus 10, clamped between 8 and 100.

This fixes the start delay symptom we've seen on some panels (vblank
timeouts with vertical white stripes at the bottom of the panel).

The current code allows the TCON clock divider to have a range between 4
and 127 when feeding the DSI controller.

The only display supported so far had a display clock rate that ended up
using a divider of 4, but testing with other displays show that only 4
seems to be functional.

This also aligns with what Allwinner is doing in their BSP, so let's just
hardcode that we want a divider of 4 when using the DSI output.

So, commit 6c1cd97b effectively makes the linux kernel starting

On the D3 and E3 SoCs the LVDS PLL clock output provides the dot clock

connected to the DPAD0 output.
Signed-off-by: NLaurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>

On the D3 and E3 platforms, the LVDS internal PLL supplies the pixel
clock to the DU. This works automatically for LVDS outputs as the LVDS
encoder is enabled through the bridge API, enabling the internal PLL and
clock output. However, when using the DU DPAD output with the LVDS
outputs turned off, the LVDS PLL needs to be controlled manually. Add an
API to do so, to be called by the DU driver.

The drivers/gpu/drm/rcar-du/ directory has to be treated as obj-y
unconditionally, as the LVDS driver could be built-in while the DU
driver is compiled as a module.

On the D3 and E3 SoCs the LVDS encoder has an extended internal PLL and
supplies a clock to the DU. That clock is used not only for the LVDS
outputs but also for the DPAD output. The LVDS encoder thus needs to be
available to the DU even when its output is disabled. Don't fail probe
in that case on D3 and E3.

Before the driver fully moved to drm_bridge and drm_panel, it was
necessary to parse DT and locate encoder and connector nodes. The
connector node is now unused and can be removed as a parameter to
rcar_du_encoder_init(). As a consequence rcar_du_encoders_init_one() can
be greatly simplified, removing most of the DT parsing.

Split the color management hooks along the single vs. double
buffered registers line. Of the currently programmed registers
GAMMA_MODE and the ilk+ pipe CSC are double buffered, the
LUTS and CHV CGM block are single buffered.

The double buffered register will be programmed during the
normal pipe update with evasion, and also during pipe enable
so that the settings will already be correct when the pipe
starts up before the planes are enabled.

The single buffered registers are currently programmed before
the vblank evade. Which is totally wrong, but we'll correct
that later.
