The I2S part has been dropped. The DesignWare HDMI block is configurable when it is synthesized - it can contain either the AHB audio interface or an I2S interface. Freescale chose to synthesize it with the AHB audio interface, and this is what my patches are geared up to provide. On Rockchip devices, they chose to synthesize it with the I2S audio block, and so they need a different driver for it. Yakir Yang has been working on that, but I've not seen anything recently. After merging his I2S patch, I found some problems and decided with Yakir that the best thing to do was to drop it. So, the result is we support HDMI audio on iMX6. The changes were merged into mainline during the 4.4 merge window, so Linux 4.4 will support iMX6 HDMI audio. -- RMK's Patch system: http://www.arm.linux.org.uk/developer/patches/ FTTC broadband for 0.8mile line: currently at 9.6Mbps down 400kbps up according to speedtest.net. _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
