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 <marek.behun@nic.cz> Reviewed-by: Stefan Roese <sr@denx.de> Signed-off-by: Stefan Roese <sr@denx.de> 2018-04-25 00:21:25 +09:00			`config CLK_MVEBU`
