similar to: [PATCH] drm: remove NULL pointer check for clk_disable_unprepare

GM20B requires an extra clock compared to GK20A. Add that information into the platform data and acquire and enable this clock if necessary. Signed-off-by: Alexandre Courbot <acourbot at nvidia.com> --- Hi Ben, The DT bindings for this have been approved but not merged yet. This means that for 4.6 GM20B will fail to probe unless the DT is patched - but this is better than the current

On Tegra186 systems with certain firmware revisions, leaving the GPU in reset can cause a hang. To prevent this, don't leave the GPU in reset.

It's dead code, the core handles all this directly now. This also allows us to unexport drm_atomic_helper_plane_set_property.

Add a platform driver for Nouveau devices declared using the device tree or platform data. This driver currently supports GK20A on Tegra platforms and is only compiled for these platforms if Nouveau is enabled. Nouveau will probe the chip type itself using the BOOT0 register, so all this driver really needs to do is to make sure the module is powered and its clocks active before calling

The vc4 driver uses empty implementations for its encoders. Replace the code with the generic simple encoder.

slim core is used as a basis for many IPs in the STi chipsets such as fdma and demux. To avoid duplicating the elf loading code in each device driver a slim rproc driver has been created. This driver is designed to be used by other device drivers such as fdma, or demux whose IP is based around a slim core. The device driver can call slim_rproc_alloc() to allocate a slim rproc and slim_rproc_put()

It's been a while since we introduced drm_dev{get/put} functions to replace reference/unreference in drm subsystem for the consistency purpose. So, with this patch, let's just replace all current use cases of drm_dev_unref() with drm_dev_put and remove the function itself. Coccinelle was used for mass-patching.
