Put particularly the PHY registers into order, bitmasks defined alongside the registers, and Use tabs for indentation. Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.com>
There was lots of register definition information dumped from the some source into the driver but unused. Remove it, and format the remaining lines according to the Linux kernel coding style. Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.com>
The D-PHY on RP1 support lane polarity swapping, and there is a standard device tree mechanism for configuring this, so tie the two together. Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.com>
