This patchset implements audio interface in HDMI drm driver. Implementation is based on ASoC generic hdmi codec driver( https://patchwork.kernel.org/patch/8713141/). V5: Helper functions are suppressed, following dicussion on IRC with Daniel Vetter. request is that other drivers that can use helper are also updated helper function patch will be proposed in a next, separed patchset. for this track, hdmi_audio_get_non_coherent_n is integrated in sti driver. V4: fixes for "video: hdmi: add helper functions for N and CTS" - typo error and additional comments - cts_1_ratio computation - warning reported by kbuild test robot - add rounded value for 297/1.001 MHz V3: - video: hdmi: add helper function for N and CTS Also used on Mediatek platform (https://patchwork.kernel.org/patch/8887341) delta vs V2: - typo fixes - if/else code optimisation - drm: sti: Add ASoC generic hdmi codec support. - typo fixes - add audio registers in debugfs information V2: RFC https://patchwork.kernel.org/patch/8091531/("video: hdmi: add helper function for N and CTS") https://patchwork.kernel.org/patch/8091561/("ASoC: hdmi-codec: Add hdmi-codec for external HDMI-encoders") - patch: video: hdmi: add helper function for N and CTS Fixes based on Russel King remarks - Duplicate function to have a separte treatment for coherent and non-coherent clocks - Add ratio field for alternate CTS value - Clock frequency in Hz for TMDS and audio clocks - Add information concerning clocks and CTS calculation. V1: This RFC is the implementation of audio HDMI on sti platform based on generic hdmi-codec driver: https://patchwork.kernel.org/patch/7215271/ ("ASoC: hdmi-codec: Add hdmi-codec for external HDMI-encoders") https://patchwork.kernel.org/patch/8062611/ ("video: hdmi: add helper function for N and CTS") Arnaud Pouliquen (1): drm: sti: Add ASoC generic hdmi codec support. drivers/gpu/drm/sti/Kconfig | 1 + drivers/gpu/drm/sti/sti_hdmi.c | 294 ++++++++++++++++++++++++++++++++++++++--- drivers/gpu/drm/sti/sti_hdmi.h | 13 ++ 3 files changed, 291 insertions(+), 17 deletions(-) -- 1.9.1 _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
