[PATCH 0/4 v2] drm: Add support of ARC PGU display controller
This series add support of ARC PGU display controller. ARC PGU is a quite simple byte streamer that gets data from the framebuffer and pushes it to hte connected encoder (DP or HDMI). It was tested on ARC SDP boards (axs101 in particular).

But may assume Jose have no access to axs103 and so this particular implementation may lack tests on axs103 platform. Still this is easy to fix - I'll try it myself now. > Further per out off-list discussion - let us have a seperate config for ARC > HS SDP > which supports the shipping single hardware configuration and add these fancy > things there as well as bumping the clk rate to 100 MHz .

Agree but first we need to introduce those additional configs. Let me draft those. In the meantime it would be helpful if you take a look at existing axs10x_defconfigs and check which option you do want to keep and what are those extra once that should go to new configs with all bells and whistles. -Alexey

Whats missing in my new FB DRM driver in ARC... waiting for console_lock to return

I'm not really sure "console_lock" has something to do with ARC architecture. At least "git grep bconsole_lock" doesn't find anything in "arch/arc". So I'd assume this is a generic thing. -Alexey
