Subject: [PATCH 007/117] drm/sun4i: Add support for D1 HDMI
|
|
|
|
D1's HDMI controller contains some platform integration changes.
|
|
It now has no external TMDS clock. The controller also supports HDCP
|
|
without an external clock or reset.
|
|
|
|
While the maximum HDMI frequency is not explicity stated, the BSP PHY
|
|
driver provides PLL configurations only up to 297 MHz, so use that as
|
|
the max frequency.
