      drm: Rely on mode_config data for fb_helper initialization · e4563f6b
      由 Gabriel Krisman Bertazi 提交于 
      Instead of receiving the num_crts as a parameter, we can read it
directly from the mode_config structure.  I audited the drivers that
invoke this helper and I believe all of them initialize the mode_config
struct accordingly, prior to calling the fb_helper.

I used the following coccinelle hack to make this transformation, except
for the function headers and comment updates.  The first and second
rules are split because I couldn't find a way to remove the unused
temporary variables at the same time I removed the parameter.

      drm: Nuke fb->pixel_format · 438b74a5
      由 Ville Syrjälä 提交于 
      Replace uses of fb->pixel_format with fb->format->format.
Less duplicated information is a good thing.

Note that coccinelle failed to eliminate the
"/* fourcc format */" comment from drm_framebuffer.h, so I had
to do that part manually.

      drm/fsl-dcu: disable planes before disabling CRTC · 3d6f3710
      由 Stefan Agner 提交于 
      After disabling and reenabling the CRTC the DCU sometimes got stuck
displaying the whole screen with a solid color. Disabling and
reenabling the CRTC did not recover from the situation. This was
often reproducable by just restarting the X-Server.

The disabling sequence is not explicitly documented. But it turns
out that disabling the planes before disabling the CRTC seems to
prevent the above situation from happening.

Use the callback ->atomic_disable instead of ->disable which allows
to use the drm_atomic_helper_disable_planes_on_crtc() helper to
disable planes before disabling the controller.

      drm/fsl-dcu: update all registers on flush · 93daeeca
      由 Stefan Agner 提交于 
      Use the UPDATE_MODE READREG bit to initiate a register transfer
on flush. This makes sure that we flush all registers only once
for all planes.

      drm/fsl-dcu: do not update when modifying irq registers · 34a515d2
      由 Stefan Agner 提交于 
      The IRQ status and mask registers are not "double buffered" according
to the reference manual. Hence, there is no extra transfer/update
write needed when modifying these registers.
