[PATCH v2 2/3] drm: switch drm_fb_xrgb8888_to_rgb565_dstclip to accept __iomem dst
Not all archs have the __io_virt() macro, so cirrus can't simply convert
pointers that way. The drm format helpers have to use memcpy_toio()
instead.
This patch makes drm_fb_xrgb8888_to_rgb565_dstclip() accept a __iomem
dst pointer and use memcpy_toio() instead of memcpy(). The helper
function (drm_fb_xrgb8888_to_rgb565_line) has been changed to process
a single scanline.

[PATCH v2 1/3] drm: switch drm_fb_memcpy_dstclip to accept __iomem dst
Not all archs have the __io_virt() macro, so cirrus can't simply convert
pointers that way. The drm format helpers have to use memcpy_toio()
instead.
This patch makes drm_fb_memcpy_dstclip() accept a __iomem dst pointer
and use memcpy_toio() instead of memcpy(). With that separating out the
memcpy loop into the drm_fb_memcpy_lines() helper isn't useful any more,
so move the code back

[PATCH 4/4] drm: add convert_lines_toio() variant, fix cirrus builds on powerpc.
The __io_virt() macro is not available on all architectures, so cirrus
can't simply pass a pointer to io memory down to the format conversion
helpers. The format conversion helpers must use memcpy_toio() instead.
Add a convert_lines_toio() variant which does just that. Switch the
drm_fb_*_dstclip() functions used by cirrus to accept a __iomem pointer
as destination and pass that down to

imo these could be put into some drm_format_helpers.c to be shared.

I agree, my long term goal is to get rid of tinydrm.ko. Just haven't got
there yet.
Gerd, if you end up using some of those functions, feel free to move
just those you need and I can do the rest later. But if you have time to
spare I wouldn't mind getting all of them moved...

[PATCH v3 5/5] drm/cirrus: rewrite and modernize driver.
Time to kill some bad sample code people are copying from ;)
This is a complete rewrite of the cirrus driver. The cirrus_mode_set()
function is pretty much the only function which is carried over largely
unmodified. Everything else is upside down.
It is a single monster patch. But given that it does some pretty
fundamental changes to the drivers workflow and also reduces the code
size by
