2016-05-08drm/msm: Drop load/unload drm_driver opsArchit Taneja
The load/unload drm_driver ops are deprecated. They should be removed as they result in creation of devices visible to userspace even before the drm_device is registered. Drop these ops and use drm_dev_alloc/register and drm_dev_unregister/unref to explicitly create and destroy the drm device in the msm platform driver's bind and unbind ops. With this in use, the drm connectors are only registered once the drm_device is registered. It also fixes the issue of stray debugfs files after the msm module is removed. With this, all the debugfs files are removed, and allows successive module insertions/removals. Signed-off-by: Archit Taneja <architt@codeaurora.org>
2016-05-08drm/msm: Centralize connector registration/unregistrationArchit Taneja
Move the drm_connector registration from the encoder(HDMI/DSI etc) drivers to the msm platform driver. 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. The memory for the connectors is unallocated when drm_mode_config_cleanup() is called during either during an error or during driver remove.

2016-05-08drm/msm/mdp4: Don't manage DSI PLL regulators in MDP driverArchit Taneja
The MDP4 driver tries to request and set voltages for regulators required by the DSI PLLs. Firstly, the MDP4 driver shouldn't manage the DSI regulators, this should be handled in the DSI driver. Secondly, it shouldn't try to set a fixed voltage for regulators. Voltage constraints should be specified on the regulator via DT and managed by the regulator core. Remove all the DSI PLL regulator related code from the MDP4 driver. It's managed in the DSI driver for MSM8960/APQ8064 already.

2016-05-08drm/msm/edp: Drop regulator_set_voltage callArchit Taneja
The eDP driver tries to set a fixed voltage for one of its regulators(vdda) before enabling it. This shouldn't be done by the driver, the voltage constraints should be specified on the regulator via DT and managed by the regulator core. A driver should call regulator_set_voltage only if it needs to change the voltage during runtime. Drop the regulator_set_voltage call. Mention in a comment the voltage that the regulator expects.

2016-05-08drm/msm/dsi: Fix regulator API abuseArchit Taneja
The voltage changing code in this driver is broken and should be removed. The driver sets a single, exact voltage on probe. Unless there is a very good reason for this (which should be documented in comments) constraints like this need to be set via the machine constraints, voltage setting in a driver is expected to be used in cases where the voltage varies at runtime. In addition client drivers should almost never be calling regulator_can_set_voltage(), if the device needs to set a voltage it needs to set the voltage and the regulator core will handle the case where the regulator is fixed voltage. If the driver simply skips setting the voltage if it doesn't have permission then it should just not bother in the first place. Originally authored by Mark Brown <broonie@kernel.org> Remove the min/max voltage data entries per SoC managed by the driver. These aren't needed as we don't try to set voltages any more.
