drm/msm/adreno: split adreno device out into it's own file

2014-09-10T15:19:08+00:00

We'd rather not duplicate these parts as support for additional gpu
generations is added.

drm/msm/mdp4: add LVDS panel support

2014-09-10T15:19:07+00:00

LVDS panel support uses the LCDC (parallel) encoder.  Unlike with HDMI,
there is not a separate LVDS block, so no need to split things into a
bridge+connector.  Nor is there is anything re-used with mdp5.

Note that there can be some regulators shared between HDMI and LVDS (in
particular, on apq8064, ext_3v3p), so we should not use the _exclusive()
variants of devm_regulator_get().

The drm_panel framework is used for panel-specific driver.

drm/msm: add rd logging debugfs

2014-06-02T11:36:11+00:00

To ease debugging, add debugfs file which can be cat/tail'd to log
submits, along with fence #.  If GPU hangs, you can look at 'gpu'
debugfs file to find last completed fence and current register state,
and compare with logged rd file to narrow down the DRAW_INDX which
triggered the GPU hang.

drm/msm: add mdp5/apq8x74

2014-01-09T19:44:06+00:00

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.

drm/msm: add hdmi support for apq8x74/mdp5

2014-01-09T19:44:05+00:00

The HDMI block is basically the same between older SoC's with mdp4
display controller, and newer ones with mdp5.

So mostly this consists of better abstracting out the different sets of
regulators, clks, etc.  In particular, for regulators and clks we can
split it up by what is needed for hot plug detect to work, and what is
needed to light up the display.

Also, 8x74 has a new phy.. a very simple one, but split out into a
different mmio space.  And with mdp5, the irq is shared with mdp, so we
don't directly register our own irq handler.

drm/msm: move irq utils to mdp_kms

2014-01-09T19:44:05+00:00

We'll want basically the same thing for mdp5, so refactor it out so it
can be shared.

drm/msm: mdp4_format -> mdp_format

2014-01-09T19:43:58+00:00

This can be shared between mdp4 and mdp5.  Both use the same set of
parameters to describe the format to the hw.

drm/msm: move mdp4 -> mdp/mdp4

2014-01-09T19:38:59+00:00

There are some little bits and pieces that mdp4 and mdp5 can share, so
move things around so that we can have both in a common parent
directory.
