Hi!
While trying to get CLUT support for the atmel_hlcdc driver, and
specifically for the emulated fbdev interface, I received some
push-back that my feeble in-driver attempts should be solved
by the core. This is my attempt to do it right.
I have obviously not tested all of this with more than a compile,
but patches 1 and 3 are enough to make the atmel-hlcdc driver
do what I need (when patched to support CLUT modes). The rest is
just lots of removals and cleanup made possible by the improved
core.
Please test, I would not be surprised if I have fouled up some
bit-manipulation somewhere in this mostly mechanical change...
Changes since v1:
- Rebased to next-20170621
- Split 1/11 into a preparatory patch, a cleanup patch and then
the meat in 3/14.
- Handle pseudo-palette for FB_VISUAL_TRUECOLOR.
- Removed the empty .gamma_get/.gamma_set fb helpers from the
armada driver that I had somehow managed to ignore but which
0day found real quick.
- Be less judgemental on drivers only providing .gamma_get and
.gamma_set, but no .load_lut. That's actually a valid thing
to do if you only need pseudo-palette for FB_VISUAL_TRUECOLOR.
- Add a comment about colliding bitfields in the nouveau driver.
- Remove gamma_set/gamma_get declarations from the radeon driver
(the definitions were removed in v1).
Cheers,
peda
