[PATCH 1/1] drm/bridge: ptn3460: Fix I2C ID table to match the reported modalias
by Javier Martinez Canillas 15 May '15

15 May '15

I2C drivers that support OF, have both an I2C and OF device ID tables that are used to fill the supported module aliases. But currently the I2C core only uses the OF table to match a device with a driver and the aliases information are always reported in the form i2c:<name>. The client->name is used as the name postfix and when booting with OF this is obtained with of_modalias_node() which drops the compatible string vendor prefix. So for I2C drivers, the I2C and OF device ID tables should be keep in sync in order to make module auto-loading to work but the I2C device entries shouldn't have the vendor prefix since that is not reported.

[PATCH early RFC 0/2] Implement ASoC HDMI codec library
by Jyri Sarha 15 May '15

15 May '15

This is on early RFC and should not be merged yet. The idea is just to share my ideas early on as there has been a lot of development going on around HDMI audio. The I2S DAI of the ASoC side patch is usable already, the spdif support has not been tested and the EDID SADs handling should use Russel's DRM ELD helper when it is ready. The tda998x patch is just to demonstrate the usage of the HDMI-codec-lib. At least the audio related DT-bindings are missing completely and the configuration is hard coded to work on Beaglebone-Black. Jean-Francois, would you consider trying the generic ASoC patch with your HW, as I can not test the spdif functionality with mine? The library could also be implemented as a separate platform driver, but then adding a pointer for private data to struct snd_soc_dai_driver, snd_soc_codec, or to snd_soc_component would be of great help. These patches, my tilcdc refactoring[1], and my latest BCLK fixes for davinci-mcasp diver [2], can found in a branch that produces a working HDMI audio on Beaglebone-Black here: https://github.com/jsarha/linux.git linux-master-bbb-hdmi-20150512 [1] http://lists.freedesktop.org/archives/dri-devel/2015-May/082537.html [2] http://mailman.alsa-project.org/pipermail/alsa-devel/2015-April/090974.html Jyri Sarha (2): ASoC: hdmi-codec-lib: Add hdmi-codec-lib for external HDMI-encoders drm/i2c: tda998x: HACK Implement primitive HDMI audio with ASoC hdmi-code-lib drivers/gpu/drm/i2c/Kconfig | 1 + drivers/gpu/drm/i2c/tda998x_drv.c | 238 +++++++++++++++++ include/sound/hdmi-codec-lib.h | 105 ++++++++ sound/soc/codecs/Kconfig | 4 + sound/soc/codecs/Makefile | 2 + sound/soc/codecs/hdmi-codec-lib.c | 536 ++++++++++++++++++++++++++++++++++++++ 6 files changed, 886 insertions(+) create mode 100644 include/sound/hdmi-codec-lib.h create mode 100644 sound/soc/codecs/hdmi-codec-lib.c -- 1.9.1

[PATCH v9.5.1 09/20] drm/dsi: Add a helper to get bits per pixel of MIPI DSI pixel format
by Liu Ying 15 May '15

15 May '15

This patch adds a helper to get bits per pixel value of MIPI DSI pixel format. The helper takes a parameter in the type 'enum mipi_dsi_pixel_format' and returns it's bits per pixel value if the parameter is valid, otherwise, it returns -EINVAL. The helper makes users' life easier to do the conversion from a specific MIPI DSI pixel format to it's bits per pixel value. Signed-off-by: Liu Ying <Ying.Liu(a)freescale.com> --- v9.5->v9.5.1: * To address Thierry Reding's comments, add a commit message to describe why the helper is useful and when to use it and fix typo in kernel-doc from 'mipi dsi' to 'MIPI DSI'. v9->v9.5: * Add kernel-doc for the new helper function to address Daniel Vetter's comment. v8->v9: * Rebase onto the imx-drm/next branch of Philipp Zabel's open git repository. v7->v8: * None. v6->v7: * None. v5->v6: * Address the over 80 characters in one line warning reported by the checkpatch.pl script. v4->v5: * None. v3->v4: * None. v2->v3: * None. v1->v2: * Thierry Reding suggested that the mipi_dsi_pixel_format_to_bpp() function could be placed at the common DRM MIPI DSI driver.

[PATCH v2 0/4] Add virtio gpu driver.
by Gerd Hoffmann 14 May '15

14 May '15

Hi, Next version of the virtio-gpu driver. Turned into a little patch series now. Most review comments should be addressed. Changes in v2: * add support for universal plane * add support for atomic modesetting * make non-failing funcs return void, kill pointless error checking * allocate vbuffers at init time, to avoid allocations in critical paths * license clarification (dual mit/gpl) * splitted vga handling into separate patch * improve error handling * codestyle fixes * misc minor tweaks here and there Still on the todo list: * sort how to handle vga compatibility best, for now the bits just have been splitted into a separate patch so they are easier to spot and don't confuse when reviewing the main parts of the driver. * properly handle page flip. cheers, Gerd Dave Airlie (1): Add virtio gpu driver.
