| * drm/msm: Change nested function to static functionMark Charlebois2014-09-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is currently a nested function in Russel King's tree for the msm HDMI driver. The last nested function was removed from the Linux kernel when the Thinkpad driver was fixed. I believe nested functions are not desired upstream, and it also breaks compilation with clang so here is a patch to change the nested function into static function. The patch works with both clang and gcc. Signed-off-by: Mark Charlebois <charlebm@gmail.com> Signed-off-by: Rob Clark <robdclark@gmail.com>
* | drm/msm/mdp4: add LVDS panel supportRob Clark2014-09-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Signed-off-by: Rob Clark <robdclark@gmail.com>

* | drm/msm/hdmi: set hdp clock rate before prepare_enableStephane Viau2014-06-22
|/ | | | | | | | | The clock driver usually complains when a clock is being prepared before setting its rate.

* drm/msm/hdmi: use gpio and HPD pollingRob Clark2014-05-30
| | | | | | | | | The hotplug detect and irq does not seem to be reliable on all devices for some reason. For now it is more reliable to use polling, and give preference to raw gpio status if it disagrees with the debounced hpd status. Signed-off-by: Rob Clark <robdclark@gmail.com>

* drm/msm: add hdmi support for apq8x74/mdp5Rob Clark2014-01-09
| | | | | | | | | | | | | | | | 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.

| | | | | | | | | | Drop the msm_connector base class, and special calls to base class methods from the encoder, and use instead drm_bridge.

* drm/msm: basic KMS driver for snapdragonRob Clark2013-08-24
| | | | | | | | | | | | | | | | | | | | | | | | | The snapdragon chips have multiple different display controllers, depending on which chip variant/version. (As far as I can tell, current devices have either MDP3 or MDP4, and upcoming devices have MDSS.) And then external to the display controller are HDMI, DSI, etc. blocks which may be shared across devices which have different display controller blocks. To more easily add support for different display controller blocks, the display controller specific bits are split out into a "kms" module, which provides the kms plane/crtc/encoder objects. The external HDMI, DSI, etc. blocks are part encoder, and part connector currently. But I think I will pull in the drm_bridge patches from chromeos tree, and split them into a bridge+connector, with the registers that need to be set in modeset handled by the bridge. This would remove the 'msm_connector' base class. But some things need to be double checked to make sure I could get the correct ON/OFF sequencing.. This patch adds support for mdp4 crtc (including hw cursor), dtv encoder (part of MDP4 block), and hdmi. Signed-off-by: Rob Clark <robdclark@gmail.com>
