2015-08-13drm/tegra: dpaux: Configure pads as I2C by defaultThierry Reding1-0/+2
The DPAUX code paths already configure the pads in AUX mode, but there is no way to reconfigure them in I2C mode for HDMI (the DPAUX module is unused in that case). Enabling the pads in I2C mode by default is the quickest way to support HDMI. Eventually this may need an explicit call in the user drivers. Signed-off-by: Thierry Reding <treding@nvidia.com>
2014-04-08drm/tegra: dp: Support address-only I2C-over-AUX transactionsThierry Reding1-0/+1
Certain types of I2C-over-AUX transactions require that only the address is transferred. Detect this by looking at the AUX message's size and set the address-only bit appropriately. Signed-off-by: Thierry Reding <treding@nvidia.com>
