Here are a brief introduction to Innosilicon HDMI IP: - Support HDMI 1.4a, HDCP 1.2 and DVI 1.0 standard compliant transmitter - Support HDMI1.4 a/b 3D function defined in HDMI 1.4 a/b spec - Digital video interface supports a pixel size of 24, 30, 36, 48bits color depth in RGB - S/PDIF output supports PCM, Dolby Digital, DTS digital audio transmission (32-192kHz Fs) using IEC60958 and IEC 61937 - The EDID and CEC function are also supported by Innosilicon HDMI Transmitter Controlle
Changes in v7: - Correct the module licnese statement (Paul) - MODULE_LICENSE("GPL"); + MODULE_LICENSE("GPL v2"); - Start indentation with tabs and fix the misspell in Kconfig (Paul) - Carry the lost device-binding document (Heiko)
Changes in v6: - Rebase the Makefile/Kconfig files which add by Chris's rockchip-mipi driver (Caeser)
Changes in v5: - Use hdmi_infoframe helper functions to packed the infoframe (Russell) - Remove the unused double wait_for_completion_timeout for ddc transfer (Russell) - Remove the unused local variable in "inno_hdmi_i2c_write()" function (Russell)
Changes in v4: - Modify the commit title "drm/rockchip: hdmi: ..." (Mark) - Correct the "DKMS" to "DPMS" (Mark) - Fix over 80 characters problems (Mark) - Remove encoder .prepare/.commit helper functions, and move the vop mode configure function into encoder .enable helper functions. (Mark)
Changes in v3: - Use encoder enable/disable function, and remove the encoder DPMS function - Keep HDMI PLL power on in standby mode
Changes in v2: - Using DRM atomic helper functions for connector init (Mark) - Remove "hdmi->connector.encoder = encoder;" (Mark) - Add the Acked-by tags from Rob - Correct the misspell "rk3036-dw-hdmi" (Heiko)

The Innosilicon HDMI is a low power HDMI 1.4 transmitter IP, and it have been integrated on some rockchip CPUs (like RK3036, RK312x).
