drm/tegra: rgb: Parameterize signal polarities#138
Merged
Conversation
This reverts commit fcae068.
The polarities of the V- and H-sync signals are encoded as flags in the display mode, so use the existing information to setup the signals for the RGB interface. Signed-off-by: Thierry Reding <treding@nvidia.com>
For some Tegra devices, like the Samsung SGH-I927, the pixel clock and data enable (DE) signal polarities have to be programmed differently than in the default case. To accommodate this, add support for configuring the signal polarities for the RGB interface based on the DRM bus flags. Signed-off-by: Maxim Schwalm <maxim.schwalm@gmail.com>
