Subject: [PATCH v5 0/2] drm: tilcdc: improved support for rev1
This series contains two patches needed to support revision 1 of the
LCD controller on da850 SoCs.
The first one implements palette loading - this is a resend of v4 of
the stand-alone patch.
The second resets the input FIFO in the DMA controller if a sync lost
error occurs and disables the interrupt completely if we're being
flooded with these errors.
v1 -> v2:
- only allocate dma memory for revision 1
v2 -> v3:
- use devres managed API for dma memory allocation
v3 -> v4:
- reinit the palette completion in tilcdc_crtc_disable()
v4 -> v5:
- add a second patch clearing the sync lost bit in case of a sync lost
error due to insufficient bandwidth
