drm/msm/hdmi: convert to msm_clk_get()

2017-10-28T15:01:34Z

We already have, as a result of upstreaming the gpu bindings, msm_clk_get() which will try to get the clock both without and with a "_clk" suffix. Use this in HDMI code so we can drop the "_clk" suffix in bindings while maintaing backwards compatibility. Signed-off-by: Rob Clark Reviewed-by: Sean Paul

drm/msm/hdmi: Set up runtime PM for HDMI

2017-08-02T11:53:46Z

Enable rudimentary runtime PM in the HDMI driver. We can't really do agressive PM toggling at the moment because we need to leave the hpd clocks enabled all the time. There isn't much benefit of creating suspend/resume ops to toggle clocks either. We just make sure that we configure the power domain in the HDMI bridge's enable/disable paths, and the HDMI connector's detect() op. Signed-off-by: Archit Taneja Signed-off-by: Rob Clark

drm/msm/hdmi: Clean up HDMI gpio DT bindings

2016-09-15T17:02:02Z

Make the following changes in the HDMI gpio bindings: - Use "-gpios" as the suffix for all the gpio names - Move all the gpios to optional, since there are platforms that use none of them. - The HPD gpio is a standard one, remove the "qcom,hdmi-tx-" prefix from it. - Remove the HDMI DDC clk/data gpios. They are just leftovers of an old way to configure pinctrl properties. - Add a missing lpm gpio used on some platforms. Make the necessary changes in the driver to incorporate these changes. There hasn't been any upstream DT that uses the HDMI bindings, so it's okay to change and move around these properties.

drm/msm: rename hdmi symbols

2016-03-03T16:55:33Z

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.

drm/msm/hdmi: Convert PHY files according to new design

2016-02-29T14:48:31Z

Remove the old PHY ops managed by hdmi_platform_config and use them as ops provided by the HDMI PHY driver. Remove the old HDMI 8960 PLL code that used the top level HDMI TX mmio base. NOTE: With this commit, HDMI functionality will break until the HDMI PHY/PLL register offsets in hdmi.xml.h aren't updated to be used as separate domains.

drm/msm/hdmi: Make HDMI core get its PHY

2016-02-29T14:48:30Z

Make HDMI core get its PHY by parsing the "phys" phandle. The core will use this PHY reference to enable/disable PHY. The driver defers probe until PHY isn't available. The DT bindings used here is the same as the one used for PHYs using the common PHY framework bindings. Signed-off-by: Archit Taneja Signed-off-by: Rob Clark

drm/msm/hdmi: Create a separate HDMI PHY driver

2016-02-29T14:48:30Z

Create a PHY device that represents the TX PHY and PLL parts of the HDMI block. This makes management of PHY specific resources (regulators and clocks) much easier, and makes the PHY and PLL usable independently. It also simplifies the core HDMI driver, which currently assigns phy ops among many other things. The PHY driver implementation done here is very similar to the PHY driver we already have for DSI. Keep the old hdmi_phy_funcs ops for now. The driver will use these until the HDMI PHY/PLL register offsets aren't considered as separate domains (i.e. their offsets start from 0). The driver doesn't use the common PHY framework for now. This is because it's hard to map our ops with the ops provided by the framework. The bindings used for this is the generic phy bindings. So, this can be adapted to the PHY framework in the future, if possible. Signed-off-by: Archit Taneja Signed-off-by: Rob Clark

drm/msm/hdmi: Clean up connector gpio usage

2016-02-29T14:48:30Z

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. Signed-off-by: Archit Taneja Signed-off-by: Rob Clark
