clk: armada-37xx-periph: Support changing clock parent and rate

2018-09-19T06:59:26Z

Add support for changing clock rate and parent clock for Armada 37xx peripheral clocks. Only clocks which can be disabled (.can_gate is true) can have parent or rate changed. This is needed so that Turris Mox can change SPI clock in device tree. Signed-off-by: Marek Behun Signed-off-by: Stefan Roese

driver: clk: Add support for clocks on Armada 37xx

The drivers are based on Linux driver by Gregory Clement. The TBG clocks support only the .get_rate method. - since setting rate is not supported, the driver computes the rates when probing and so subsequent calls to the .get_rate method do not read the corresponding registers again The peripheral clocks support methods .get_rate, .enable and .disable. - the .set_parent method theoretically could be supported on some clocks (the parent would have to be one of the TBG clocks) - the .set_rate method would have to try all the divider values to find the best approximation of a given rate, and it doesn't seem like this should be needed in U-Boot, therefore not implemented Signed-off-by: Marek Behun Reviewed-by: Stefan Roese Signed-off-by: Stefan Roese
