linux-toradex.git/drivers/gpu/drm/msm/msm_kms.h, branch v3.18.16 Linux kernel for Apalis and Colibri modules drm/msm: add mdp5/apq8x74 2014-01-09T19:44:06+00:00 Rob Clark robdclark@gmail.com 2013-11-30T22:51:47+00:00 06c0dd96bfbba8a9368ffd7c4b12d3bfed37001d Add support for the new MDP5 display controller block. The mapping between parts of the display controller and KMS is: plane -> PIPE{RGBn,VIGn} \ crtc -> LM (layer mixer) |-> MDP "device" encoder -> INTF / connector -> HDMI/DSI/eDP/etc --> other device(s) Unlike MDP4, it appears we can get by with a single encoder, rather than needing a different implementation for DTV, DSI, etc. (Ie. the register interface is same, just different bases.) Also unlike MDP4, all the IRQs for other blocks (HDMI, DSI, etc) are routed through MDP. And finally, MDP5 has this "Shared Memory Pool" (called "SMP"), from which blocks need to be allocated to the active pipes based on fetch stride. Signed-off-by: Rob Clark <robdclark@gmail.com> 
Add support for the new MDP5 display controller block.  The mapping
between parts of the display controller and KMS is:

  plane   -> PIPE{RGBn,VIGn}             \
  crtc    -> LM (layer mixer)            |-> MDP "device"
  encoder -> INTF                        /
  connector -> HDMI/DSI/eDP/etc          --> other device(s)

Unlike MDP4, it appears we can get by with a single encoder, rather
than needing a different implementation for DTV, DSI, etc.  (Ie. the
register interface is same, just different bases.)

Also unlike MDP4, all the IRQs for other blocks (HDMI, DSI, etc) are
routed through MDP.

drm/msm: move irq utils to mdp_kms 2014-01-09T19:44:05+00:00 Rob Clark robdclark@gmail.com 2013-11-30T22:24:22+00:00 9e0efa63565511dc75846e6b036a4b80e92b9a98 We'll want basically the same thing for mdp5, so refactor it out so it can be shared. Signed-off-by: Rob Clark <robdclark@gmail.com>
