I just talked with Sima about it in the hallway at XDC. I'm fine with those patches in principle, but it looks to me that simpledrm doesn't have support for power domains and we'll want that :) Thanks! Maxime

Ah, my bad I didn't look in drm-misc-next All good then, thanks! Maxime
From: Thierry Reding <treding@nvidia.com> Hi, This contains two patches that bring simplefb up to feature parity with simpledrm. The patches add support for the "memory-region" property that provides an alternative to the "reg" property to describe the memory used for the framebuffer and allow attaching the simple-framebuffer device to one or more generic power domains to make sure they aren't turned off during the boot process and take down the display configuration. Thanks, Thierry Thierry Reding (2): fbdev/simplefb: Support memory-region property fbdev/simplefb: Add support for generic power-domains drivers/video/fbdev/simplefb.c | 128 +++++++++++++++++++++++++++++++-- 1 file changed, 121 insertions(+), 7 deletions(-)
