This commit adds support for both DSI outputs found on Tegra. Only very minimal functionality is implemented, so advanced features like ganged mode won't work. Due to the lack of other test hardware, some sections of the driver are hardcoded to work with Dalmore. Signed-off-by: NThierry Reding <treding@nvidia.com>

When an output is disabled, its DPMS mode is usually set to off. Instead of only disabling the panel (if one is attached), turn the output off entirely to save more power. HDMI doesn't have any panels attached, so it previously didn't save any power at all. With this commit, however, the complete HDMI interface will be turned off, therefore allowing an attached monitor to go into a standby mode. Signed-off-by: NThierry Reding <treding@nvidia.com>

The DRM core doesn't track enable and disable state of encoders and/or connectors, so calls to the output's .enable() and .disable() are not guaranteed to be balanced. Track the enable state internally so that calls to regulator and clock frameworks remain balanced. Signed-off-by: NThierry Reding <treding@nvidia.com>

The ARCH_MULTIPLATFORM dependency was introduced back when Tegra didn't support multiplatform yet as a means to allow the driver to be easily compile-tested along with other DRM drivers. In the meantime, the new COMPILE_TEST Kconfig option has been introduced for exactly that purpose, so use that instead to clarify the intention. Signed-off-by: NThierry Reding <treding@nvidia.com>

Treat both negative and zero return values from clk_round_rate() as errors. This is needed since subsequent patches will convert clk_round_rate()'s return value to be an unsigned type, rather than a signed type, since some clock sources can generate rates higher than (2^31)-1 Hz. Eventually, when calling clk_round_rate(), only a return value of zero will be considered a error. All other values will be considered valid rates. The comparison against values less than 0 is kept to preserve the correct behavior in the meantime.

When debugfs support isn't enabled, gcc complains about some variables being unused. To avoid further #ifdefery, move debugfs specific setup code into static functions and use IS_ENABLED(CONFIG_DEBUG_FS) to have the compiler, rather than the preprocessor, discard them when unused. The advantage of doing it this way is that all the code will be compile-tested whether or not debugfs support is enabled. Signed-off-by: NThierry Reding <treding@nvidia.com>

Add a driver for simple panels. Such panels can have a regulator that provides the supply voltage and a separate GPIO to enable the panel. Optionally the panels can have a backlight associated with them so it can be enabled or disabled according to the panel's power management mode. Support is added for two panels: An AU Optronics 10.1" WSVGA and a Chunghwa Picture Tubes 10.1" WXGA panel. Signed-off-by: NThierry Reding <treding@nvidia.com>

Add a very simple framework to register and lookup panels. Panel drivers can initialize a DRM panel and register it with the framework, allowing them to be retrieved and used by display drivers. Currently only support for DPMS and obtaining panel modes is provided. However it should be sufficient to enable a large number of panels. The framework should also be easily extensible to support more sophisticated kinds of panels such as DSI. The framework hasn't been tied into the DRM core, even though it should be easily possible to do so if that's what we want. In the current implementation, display drivers can simple make use of it to retrieve a panel, obtain its modes and control its DPMS mode. Note that this is currently only tested on systems that boot from a device tree. No glue code has been written yet for systems that use platform data, but it should be easy to add.

MIPI DSI bus allows to model DSI hosts and DSI peripherals using the Linux driver model. DSI hosts are registered by the DSI host drivers. During registration DSI peripherals will be created from the children of the DSI host's device tree node. Support for registration from board-setup code will be added later when needed. DSI hosts expose operations which can be used by DSI peripheral drivers to access associated devices.

Since commit ec39f64b ("drm/radeon/dpm: Convert to use devm_hwmon_register_with_groups") radeon_hwmon_init() is using hwmon_device_register_with_groups(), which sets `rdev' as a device private driver_data, while hwmon_attributes_visible() and radeon_hwmon_show_temp_thresh() are still waiting for `drm_device'.

Also request kernel ttm_buffer objects for buffer objects that obviously aren't visible to user-space, and save some device address space. The accounting was broken in a couple of ways: 1) We did not differentiate between user dma buffers and kernel dma buffers. 2) The ttm_bo_acc_size function is broken in that it a) Doesn't take into account the size of the optional dma address array, b) Doesn't take into account the fact that drivers typically embed the ttm_tt structure. This needs to be fixed in ttm, but meanwhile provide a vmwgfx-specific function to do the job.
