Merge tag 'exynos-drm-next-for-v5.17' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into drm-next Four cleanups - Replacing lagacy gpio interface of dsi driver with gpiod one. - Implementing a generic GEM object mmap and use it instead of exynos specific one. - Dropping the use of label from dsi driver. Which also fixes a build warning. - Just trivial cleanup by dropping unnecessay code. Signed-off-by:

drm/tegra: Changes for v5.17-rc1 This contains a fairly large rework that makes the buffer objects behave more according to what the DMA-BUF infrastructure expects. A buffer object cache is implemented on top of that to make certain operations such as page-flipping more efficient by avoiding needless map/unmap operations. This in turn is useful to implement asynchronous commits to support legacy cursor updates. Another fairly big addition is the NVDEC driver. This uses the updated UABI introduced in v5.15-rc1 to provide access to the video decode engines found on Tegra210 and later. This also includes some power management improvements that are useful on older devices in particular because they, together with a bunch of other changes across the kernel, allow the system to scale down frequency and voltages when mostly idle and prevent these devices from becoming excessively hot. The remainder of these changes is an assortment of cleanups and minor fixes. Signed-off-by:

Dropped the use of 'out' label from exynos_dsi_register_te_irq function because the label isn't needed. This patch returns an error in each error case directly not going to 'out' label. With this patch build warning[1] is also fixed, which was reported by kernel test robot <lkp@intel.com> [1] https://www.spinics.net/lists/dri-devel/msg323803.htmlReported-by:

Moving the driver-specific mmap code into a GEM object function allows for using DRM helpers for various mmap callbacks. The respective exynos functions are being removed. The file_operations structure exynos_drm_driver_fops is now being created by the helper macro DEFINE_DRM_GEM_FOPS(). Signed-off-by:

DMA buffers of 2D/3D engines aren't mapped properly when CONFIG_ARM_DMA_USE_IOMMU=y. The memory management code of Tegra DRM driver has a longstanding overhaul overdue and it's not obvious where the problem is in this case. Hence let's add back the old workaround which we already had sometime before. It explicitly detaches DRM devices from the offending implicit IOMMU domain. This fixes a completely broken 2d/3d drivers in case of ARM32 multiplatform kernel config.

The HDMI on Tegra belongs to the core power domain and we're going to enable GENPD support for the core domain. Now HDMI driver must use OPP API for driving the controller's clock rate because OPP API takes care of reconfiguring the domain's performance state based on HDMI clock rate.

Add host1x_channel_stop() which waits till channel becomes idle and then stops the channel hardware. This is needed for supporting suspend/resume by host1x drivers since the hardware state is lost after power-gating, thus the channel needs to be stopped before client enters into suspend.

Add runtime PM and OPP support to the Host1x driver.

Upon failure, dma_alloc_coherent() returns NULL. If that does happen, passing some uninitialised stack contents to dma_mapping_error() - which belongs to a different API in the first place - has precious little chance of detecting it. Also include the correct header, because the fragile transitive inclusion currently providing it is going to break soon.

Asus Transformer TF700T is a Tegra30 tablet device which uses RGB->DSI bridge that requires a precise clock rate in order to operate properly. Tegra30 has a dedicated PLL for each display controller, hence the PLL rate can be changed freely. Allow PLL rate changes on Tegra30+ for RGB output. Configure the clock rate before display controller is enabled since DC itself may be running off this PLL and it's not okay to change the rate of the active PLL that doesn't support dynamic frequency switching since hardware will hang.

Asus TF700T tablet uses TC358768 DPI->DSI bridge that sits between Tegra's DPI output and display panel input. Bridge requires to have stable PCLK output before RGB encoder is enabled because it uses PCLK by itself to clock internal logic and bridge is programmed before Tegra's encoder is enabled. Hence the PCLK clock shifter must be programmed when CRTC is enabled, otherwise clock is unstable and bridge hangs because of it. Move the shifter programming from RGB encoder into CRTC.
