From: Gabriel Fernandez <gabriel.fernandez@xxxxxx>
This patch lists STM32F7's RCC numeric constants.
It will be used by clock and reset drivers, and DT bindings.
Signed-off-by: Gabriel Fernandez <gabriel.fernandez@xxxxxx>
can you please split this commit ? (one part for binding and another for DT)
Thanks in advance
Alex
