Similar to the previous commit, convert drivers open coding OF graph parsing to use drm_of_find_panel_or_bridge instead. This changes some error messages to debug messages (in the graph core). Graph connections are often "no connects" depending on the particular board, so we want to avoid spurious messages. Plus the kernel is not a DT validator.

Convert drivers to use the new of_graph_get_remote_node() helper instead of parsing the endpoint node and then getting the remote device node. Now drivers can just specify the device node and which port/endpoint and get back the connected remote device node. The details of the graph binding are nicely abstracted into the core OF graph code. This changes some error messages to debug messages (in the graph core). Graph connections are often "no connects" depending on the particular board, so we want to avoid spurious messages.

2016-09-22drm: Don't swallow error codes in drm_dev_alloc()Tom Gundersen1-2/+2
There are many reasons other than ENOMEM that drm_dev_init() can fail. Return ERR_PTR rather than NULL to be able to distinguish these in the caller.

2016-08-29drm/atomic-helper: Add NO_DISABLE_AFTER_MODESET flag support for plane commitLiu Ying1-2/+4
Drivers may set the NO_DISABLE_AFTER_MODESET flag in the 'flags' parameter of the helper drm_atomic_helper_commit_planes() if the relevant display controllers(e.g., IPUv3 for imx-drm) require to disable a CRTC's planes when the CRTC is disabled. The helper would skip the ->atomic_disable call for a plane if the CRTC of the old plane state needs a modesetting operation. Of course, the drivers need to disable the planes in their CRTC disable callbacks since no one else would do that.

2016-08-11drm/mediatek: set mt8173 dithering functionBibby Hsieh6-20/+89
Some panels only accept bpc (bit per color) 6-bit. But, the default bpc in mt8173 display data path is 8-bit. If we didn't enable dithering function to convert bpc, display cannot show the smooth grayscale image. In mt8173, the dithering function in OD (OverDrive) and GAMMA module, we have to config them with connector->display_mode.bpc when CRTC initial. 1. Clear the default value at *_DITHER_5 and *_DITHER_7 register. 2. Calculate the LSB_ERR_SHIFT bits and ADD_LSHIFT bits two values. i.e. Input bpc of OD is 10 bits, we assume the bpc of panel is 6-bit, so, we need to set 4-bit to LSB_ERR_SHIFT and ADD_LSHIFT bits respectively. 3. Then, set the OD or GAMMA to dithering mode depends on path-1 or path-2. Signed-off-by: Bibby Hsieh <[email protected]> Signed-off-by: Philipp Zabel <[email protected]>

2016-08-11drm/mediatek: add ARM_SMCCC dependencyArnd Bergmann1-0/+1
ARM SMCCC is only set for ARMv7 and ARMv8 CPUs, but we currently allow the driver to be build for older architecture levels as well, which results in a link failure: drivers/gpu/built-in.o: In function `mtk_hdmi_hw_make_reg_writable': :(.text+0x1e737c): undefined reference to `arm_smccc_smc' This adds a Kconfig dependency. The patch applies on my two previous fixes that are not yet applied, so please apply all three to get randconfig builds to work correctly.
