fc275a74eb drm/i2c: tda998x: free the CEC device on encoder_destroy 
The cec i2c device is created in tda998x_encoder_init() when the DRM

This patch frees it when the DRM driver is unloaded.

Fix a bug that was introduced in commit c4c11dd160 ("drm/i2c: tda998x:
add video and audio input configuration") when Sebastian cleaned up my
original patch.  Without this being fixed, audio is muted when the
display is turned off, never to be re-enabled.

179f1aa407 drm/i2c: tda998x: prepare for broken sync workaround 
Some LCD controller cannot provide valid VESA style sync, i.e. coincident
HS/VS edges. First, this patch adds hskew passed from the adjusted_mode to
reference pixel calculation to allow those controllers to add an offset
relative to the expected reference pixel.

5e74c22cd1 drm/i2c: tda998x: prepare for video input configuration 
The video-input-port (VIP) is highly configurable. This prepares
current driver to allow to configure VIP configuration, as some
boards connect lcd controller and TDA998x "pin-swapped" and depend
on VIP to swap the pins by register configuration.

bcb2481df0 drm/i2c: tda998x: ensure VIP output mux is properly set 
When switching between various drivers for this device, it's possible
that some critical registers are left containing values which affect
the device operation.  One such case encountered is the VIP output
mux register.  This defaults to 0x24 on powerup, but other drivers may
set this to 0x12.  This results in incorrect colours.

Fix this by ensuring that the register is always set to the power on
default setting.
