This is a respin of my rpi-dt-clocks series (also available at
https://github.com/anholt/linux/tree/rpi-dt-clocks).  New in this
version is mentioning the clk subsystem for drivers/clk/* patches,
some better documentation of behavior in clk-raspberrypi.c, and a new
patch at the tail of the series for updating the EMMC clock.
