Hello there,
This RFC introduces support for the FS035VG158 LCD panel, cleaning up
the nv3052c driver on the way and documentating existing panel code.
John.
v2 -> v3:
- Dropped patches that add extra sleep time
v1 -> v2:
- Fixed a variable declaration style error
- Cleaned up device tree yaml
John Watts (7):
drm/panel: nv3052c: Document known register names
drm/panel: nv3052c: Add SPI device IDs
drm/panel: nv3052c: Allow specifying registers per panel
drm/panel: nv3052c: Add Fascontek FS035VG158 LCD display
dt-bindings: display: panel: Clean up leadtek,ltk035c5444t properties
dt-bindings: vendor-prefixes: Add fascontek
dt-bindings: display: panel: add Fascontek FS035VG158 panel

SPI drivers needs their own list of compatible device IDs in order
for automatic module loading to work. Add those for this driver.
