Driver tries to disable sclk_hdmi during re-parenting, to avoid possible glitches. It is ineffective as the clock is used also by other devices (mixer). Anyway driver works without disabling sclk_hdmi. Signed-off-by:

Currently driver tries to set specific HDMI-PHY registers in three situations: - before reset, - before power off, - after applying HDMI-PHY configuration. First two cases seems to be unnecessary - register contents will be lost anyway. The third case can be merged with HDMI-PHY configuration by fixing the last byte of configuration data. The patch has been tested with following platforms: - exynos4210-universal_c210, - exynos4412-odroidu3, - exynos5422-odroidxu3. Signed-off-by:

This compatible was marked as deprecated in Jun 2013 and it is not used since then. Additionally its driver data points to wrong pll settings, so it cannot work anyway. Signed-off-by:

A bit smaller pull this time. Few minor things, plus initial support for msm8996 (snapdragon 820).. Sorry, a bit latish, was hoping to get some 8960/8064 DSI stuff included. But still waiting on the v2 of the patchset (just pending some minor review comments). It would be nice to get the DSI patches merged since it would help some folks trying to get upstream kernel running on n4/n7 and xperia z and wanting to write some more panel drivers. Also, waiting for OCMEM driver to get merged via other trees and then I have a small bit to go along with that to make the gpu actually work on devices w/ OCMEM (snapdragon 800, 805, etc). So maybe a second later pull req, time permitting. * 'msm-next' of git://people.freedesktop.org/~robclark/linux: drm/msm: Remove local fbdev emulation Kconfig option drm/msm/mdp5: Basic support for MDP5 v1.7 (MSM8996) drm/msm/mdp: Add Software Pixel Extension support drm/msm/mdp5: Use the newly introduced enum mdp_component_type drm/msm/hdmi: Add basic HDMI support for msm8996 drm/msm/mdp5: Avoid printing error messages for optional clocks drm/msm: Fix IOMMU clean up path in case msm_iommu_new() fails drm/msm/mdp5: remove the cfg pointer from SMP struct drm/msm/dsi: Updata LNn_CFG4 register settings for 28nm PHY drm: msm: dsi: Don't attempt changing voltage of switches drm/msm: update generated headers

DRM_MSM_FBDEV config is used to enable/disable fbdev emulation for the msm kms driver. Replace this with the top level DRM_FBDEV_EMULATION config option where applicable. This also prevents build breaks caused by undefined drm_fb_helper_* functions when legacy fbdev support was disabled. Signed-off-by:

In order to produce an image, the scalar needs to be fed extra pixels. These top/bottom/left/right values depend on a various of factors, including resolution, scaling type, phase step and initial phase. Pixel Extension are programmed by hardware in most targets - and can be overwritten by software. For some targets (e.g.: msm8996), software *must* program those registers. In order to ease this computation, let's always use bilinear filters, which are easier to program from kernel. Eventually, all of these values will come down from user space for better quality.

The current behavior is to try to get optional clocks and print a dev_err message in case of failure. This looks rather confusing and may increase with the amount of optional clocks. We may need a cleaner way to handle per-device clocks but in the meantime, let's reduce the amount of dev_err messages during the probe. Signed-off-by:

This pull request introduces the vc4 driver, for kernel modesetting on the Raspberry Pi (bcm2835/bcm2836 architectures). It currently supports a display plane and cursor on the HDMI output. The driver doesn't do 3D, power management, or overlay planes yet. [airlied: fixup the enable/disable vblank APIs] Acked-by:

This is enough for fbcon and bringing up X using xf86-video-modesetting. It doesn't support the 3D accelerator or power management yet. v2: Drop FB_HELPER select thanks to Archit's patches. Do manual init ordering instead of using the .load hook. Structure registration more like tegra's, but still using the typical "component" code. Drop no-op hooks for atomic_begin and mode_fixup() now that they're optional. Drop sentinel in Makefile. Fix minor style nits I noticed on another reread. v3: Use the new bcm2835 clk driver to manage pixel/HSM clocks instead of having a fixed video mode. Use exynos-style component driver matching instead of devicetree nodes to list the component driver instances. Rename compatibility strings to say bcm2835, and distinguish pv0/1/2. Clean up some h/vsync code, and add in interlaced mode setup. Fix up probe/bind error paths. Use bitops.h macros for vc4_regs.h v4: Include i2c.h, allow building under COMPILE_TEST, drop msleep now that other bugs have been fixed, add timeouts to cpu_relax() loops, rename hpd-gpio to hpd-gpios.

VC4 is the GPU (display and 3D) subsystem present on the 2835 and some other Broadcom SoCs. This binding follows the model of msm, imx, sti, and others, where there is a subsystem node for the whole GPU, with nodes for the individual HW components within it. v2: Extend the commit message, fix several nits from Stephen Warren. v3: Rename the compatibility strings, clean up node names, drop the unnecessary lists of components. Use compatibility strings for choosing CRTC HVS channel numbers. Document the HDMI clock usage. v4: Whitespace fix, expand acronyms, move to display/ instead of gpu/, rename "hpd-gpio" to "hpd-gpios". Signed-off-by:

The plane reset handler frees the plane state and allocates a new default state, but when doing so attempt to free the plane state using the base plane state pointer instead of casting it to the driver-specific state object that has been allocated. Fix it by using the rcar_du_plane_atomic_destroy_state() function to destroy the plane state instead of duplicating the code. Signed-off-by:

In commit bbb1e524 Author: Rob Clark <robdclark@gmail.com> Date: Tue Aug 25 15:35:58 2015 -0400 drm/fb-helper: atomic restore_fbdev_mode().. we've forgotten to do the plane->old_fb refcount dance for pan_display_atomic, which can result in refcount leaks if the current configuration is not from fbcon. Which apparently can happen when vt-switching - fbcon does a pan first before a set_par. OCD-align function parameters while at it. v2: Actually git add the OCD.
