2018-11-09drm/vc4: Prefer PPF over TPZ when dst >= 2/3 srcBoris Brezillon
The HVS spec recommends using PPF when the downscaling ratio is between 2/3 and 1. Let's modify vc4_get_scaling_mode() to follow this recommendation.

2018-11-09drm/vc4: ->x_scaling[1] should never be set to VC4_SCALING_NONEBoris Brezillon
For the YUV conversion to work properly, ->x_scaling[1] should never be set to VC4_SCALING_NONE, but vc4_get_scaling_mode() might return VC4_SCALING_NONE if the horizontal scaling ratio exactly matches the horizontal subsampling factor. Add a test to turn VC4_SCALING_NONE into VC4_SCALING_PPF when that happens. The old ->x_scaling[0] adjustment is dropped as I couldn't find any mention to this constraint in the spec and it's proven to be unnecessary (I tested various multi-planar YUV formats with scaling disabled, and all of them worked fine without this adjustment).

2018-11-09drm/sun4i: tcon: Support an active-low DE signal with RGB interfacePaul Kocialkowski
Some panels need an active-low data enable (DE) signal for the RGB interface. This requires flipping a bit in the TCON0 polarity register when setting up the mode for the RGB interface. Match the associated bus flag and use it to set the polarity inversion bit for the DE signal when required.

2018-11-09drm/sun4i: tcon: Get the connector from the encoder in RGB setupPaul Kocialkowski
Features such as dithering and pixel data edge configuration currently rely on the panel registered with the TCON driver. However, bridges are also supported in addition to panels for RGB setup. Instead of retrieving the connector from the panel, get it from the encoder with the dedicated helper. Even in the case of bridges, the connector is registered with the encoder from our driver and is accessible when iterating connectors.

However, judging by the code, PHY is very similar to older Synopsys HDMI PHY described in i.MX6 documentation. Most registers seem to be the same. According to i.MX6 documentation, mpll settings are based on pixel clock and are not specific to each SoC.

2018-11-02drm: Add macro to export functions only when CONFIG_DRM_DEBUG_SELFTEST is ↵Alexandru Gheorghe
enabled If we want to be able to write drmselftests for non-static core functions that are not intended to be used by drivers we need this functions to be exported. This adds a macro that is tied of CONFIG_DRM_DEBUG_SELFTEST, and uses that to export drm_internal_framebuffer_create, in order for subsequent patches to be able to test it.

2018-11-02drm: Extend framebuffer_check to handle formats with cpp/char_per_block 0Alexandru Gheorghe
For formats that are supported only with non-linear modifiers it doesn't make to much sense to define cpp or char_per_block, so that will be set to 0. This patch adds a restriction to force having a modifier attached when cpp/char_per_block is 0, and to bypass checking the pitch restriction. This had been discussed here.

2018-11-02drm/fourcc: Add fourcc for Mali linear tiled formatsAlexandru Gheorghe
Mali-DP implements a number of tiled yuv formats which are not currently described in drm_fourcc.h. This adds those definitions and describes their memory layout by using the newly added char_per_block, block_w, block_h.

2018-11-02drm/fourcc: Add char_per_block, block_w and block_h in drm_format_infoAlexandru Gheorghe
For some pixel formats .cpp structure in drm_format info it's not enough to describe the peculiarities of the pixel layout, for example tiled formats or packed formats at bit level. What's implemented here is to add three new members to drm_format_info that could describe such formats: - char_per_block[3] - block_w[3] - block_h[3] char_per_block will be put in a union alongside cpp, for transparent compatibility with the existing format descriptions. Regarding, block_w and block_h they are intended to be used through their equivalent getters drm_format_info_block_width / drm_format_info_block_height, the reason of the getters is to abstract the fact that for normal formats block_w and block_h will be unset/0, but the methods will be returning 1. Additionally, convenience function drm_format_info_min_pitch had been added that computes the minimum required pitch for a given pixel format and buffer width. Using that the following drm core functions had been updated to generically handle both block and non-block formats: - drm_fb_cma_get_gem_addr: for block formats it will just return the beginning of the block. - framebuffer_check: Use the newly added drm_format_info_min_pitch. - drm_gem_fb_create_with_funcs: Use the newly added drm_format_info_min_pitch. - In places where is not expecting to handle block formats, like fbdev helpers I just added some warnings in case the block width/height are greater than 1. Changes since v3: - Add helper function for computing the minimum required pitch. - Improve/cleanup documentation Changes since v8: - Fixed build on 32bits arm architectures, with: - return DIV_ROUND_UP((u64)buffer_width * info->char_per_block[plane], + return DIV_ROUND_UP_ULL((u64)buffer_width * info->char_per_block[plane], Reviewed-by: Brian Starkey <brian.starkey@arm.com> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Alexandru Gheorghe <alexandru-cosmin.gheorghe@arm.com> Link: https://patchwork.freedesktop.org/patch/msgid/20181101170055.5433-1-alexandru-cosmin.gheorghe@arm.com
2018-11-02drm/panel: Add simple panel mode for the ARM RTSMLinus Walleij
Having failed any attempts at a more generic solution, I fall back to the very specific solution: define a simple panel for the ARM RTSM emulated platforms. I am doing this so we can convert all old users from the previous fbdev driver to the PL111 DRM driver. This works fine as far as I can test, provided the device tree for RTSM AEMv8 is augmented accordingly.

2018-11-01drm/tilcdc: Use drm_fbdev_generic_setup()Noralf Trønnes
The CMA helper is already using the drm_fb_helper_generic_probe part of the generic fbdev emulation. This patch makes full use of the generic fbdev emulation by using its drm_client callbacks. This means that drm_mode_config_funcs->output_poll_changed and drm_driver->lastclose are now handled by the emulation code. Additionally fbdev unregister happens automatically on drm_dev_unregister(). The drm_fbdev_generic_setup() call is put after drm_dev_register() in the driver. This is done to highlight the fact that fbdev emulation is an internal client that makes use of the driver, it is not part of the driver as such. If fbdev setup fails, an error is printed, but the driver succeeds probing.
