2019-09-03drm/msm/hdmi: Convert to use GPIO descriptorsLinus Walleij
This switches the MSM HDMI code to use GPIO descriptors. Normally we would fetch the GPIOs from the device with the flags GPIOD_IN or GPIOD_OUT_[LOW|HIGH] to set up the lines immediately, but since the code seems eager to actively drive the lines high/low when turning HDMI on and off, we just fetch the GPIOs as-is and keep the code explicitly driving them. The old code would try legacy bindings (GPIOs without any "-gpios" suffix) but this has been moved to the gpiolib as a quirk by the previous patch.

2018-12-03drm/msm/hdmi: Enable HPD after HDMI IRQ is set upTodor Tomov
SoCs that contain MDP5 have a top level wrapper called MDSS that manages locks, power and irq for the sub-blocks within it. Irq for HDMI is also routed through the MDSS. Shortly after the Hot Plug Detection (HPD) is enabled in HDMI, HDMI interrupts are recieved by the MDSS interrupt handler. However at this moment the HDMI irq is still not mapped to the MDSS irq domain so the HDMI irq handler cannot be called to process the interrupts. This leads to a flood of HDMI interrupts on CPU 0. If we are lucky to have the HDMI initialization running on a different CPU, it will eventually map the HDMI irq to MDSS irq domain, the next HDMI interrupt will be handled by the HDMI irq handler, the interrupt flood will stop and we will recover. If the HDMI initialization is running on CPU 0, then it cannot complete and there is nothing to stop the interrupt flood on CPU 0. The system is stuck. Fix this by moving the HPD enablement after the HDMI irq is mapped to the MDSS irq domain.

This will simplify the task of ensuring that the connectors are registered only after the drm_device itself is registered. The connectors' destroy ops are made to use kzalloc instead of devm_kzalloc to ensure that that the connectors can be successfully unregistered when the msm driver module is removed.

Global symbols in the kernel should be prefixed by the name of the subsystem and/or driver to avoid conflicts when all code is built-in. In this case, function names like 'hdmi_register' or 'hdmi_set_mode' are way too generic for an MSM specific DRM driver, so I'm renaming them all to msm_hdmi_* here. I also rename a lot of the 'static' symbols along with the global names for consistency, even though those are relatively harmless; they might only be slightly confusing when they show up in backtraces.

2016-02-29drm/msm/hdmi: Clean up connector gpio usageArchit Taneja
Make gpio allocation and usage iterative by parsing the gpios on a given platform from a list. This gives us flexibility over what all gpios exist for a platform, whether they are input or output, and what value they should be set to. In particular, this will make HDMI on 8x96 platforms easier to integrate with the driver, as it doesn't have a HPD gpio input to them. Also, it cleans things up a bit. We still use the legacy gpio api here, as we might need to backport this driver to downstream kernels.

2015-02-01drm/msm: fix fallout of atomic dpms changesRob Clark
As a result of atomic DPMS support, the various prepare/commit hooks get called in a way that msm dislikes. We were expecting prepare/commit to bracket a modeset, which is no longer the case. This was needed to hold various extra clk's (such as interface clks) on while we are touching registers, and in the case of mdp4 holding vblank enabled. The most straightforward way to deal with this, since we already have our own atomic_commit(), is to just handle prepare/commit internally to the driver (with some additional vfuncs for mdp4 vs mdp5), and switch everything over to instead use the new enable/disable hooks. It doesn't really change too much, despite the code motion. What used to be in the encoder/crtc dpms() fxns is split out into enable/disable. We should be able to drop our own enable-state tracking, as the atomic helpers should do this for us. But keeping that for the short term for extra debugging as atomic stablizes.

2014-11-21drm/msm/hdmi: remove useless krefRob Clark
A left-over from prior to component framework. The original intent was to deal with hdmi getting unloaded before the master component, but that isn't really going to work anyways. These days with the component framework taking care to unload the master component first, we don't have to worry about this. Signed-off-by: Rob Clark <robdclark@gmail.com>

2014-06-22drm/msm/hdmi: set hdp clock rate before prepare_enableStephane Viau
The clock driver usually complains when a clock is being prepared before setting its rate. It is the case here for "core_clk" which needs to be set at 19.2 MHz before we attempt a prepare_enable(). Signed-off-by: Stephane Viau <sviau@codeaurora.org> Signed-off-by: Rob Clark <robdclark@gmail.com>

2014-05-30drm/msm/hdmi: use gpio and HPD pollingRob Clark
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>
2014-01-09drm/msm: add hdmi support for apq8x74/mdp5Rob Clark
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.

2013-09-02drm/msm: convert to drm_bridgeRob Clark
Drop the msm_connector base class, and special calls to base class methods from the encoder, and use instead drm_bridge. This allows for a cleaner division between the hdmi (and in future dsi) blocks, from the mdp block. Signed-off-by: Rob Clark <robdclark@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
2013-08-24drm/msm: basic KMS driver for snapdragonRob Clark
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>
