Subject: [PATCH 105/117] phy: allwinner: phy-sun6i-mipi-dphy: Add a variant
|
|
power-on hook
|
|
|
|
The A100 variant uses the same values for the timing registers, and it
|
|
uses the same final power-on sequence, but it needs a different analog
|
|
register configuration in the middle. Support this by moving the
|
|
variant-specific parts to a hook provided by the variant.
