2019-04-25clk: imx8: add i.MX8QM clk driverPeng Fan
Add i.MX8QM clk driver, SDHC/FEC/UART/I2C supported. Signed-off-by: Peng Fan <peng.fan@nxp.com>
2019-04-25clk: imx8: split code into common and soc specific partPeng Fan
To make it easy to add new clk driver for i.MX8, split the code into common part and SoC specific part. Make the get/set/enable non static and introduce a num_clks for soc_clk_dump, because the arrays are moved to clk-imx8qxp.c. Signed-off-by: Peng Fan <peng.fan@nxp.com>

2019-01-30sunxi: clk: enable clk and reset for CCU devicesAndre Przywara
Some Allwinner clock devices have parent clocks and reset gates itself, which need to be activated for them to work. Add some code to just assert all resets and enable all clocks given. This should enable the A80 MMC config clock, which requires both to be activated. The full CCU devices typically don't require resets, and have just fixed clocks as their parents. Since we treat both as optional and enabling fixed clocks is a NOP, this works for all cases, without the need to differentiate between those clock types.

2019-01-29sunxi: clk: A80: add MMC clock supportAndre Przywara
The A80 handles resets and clock gates for the MMC devices differently, outside of the CCU IP block. Consequently we have a separate clock device with a separate binding for that. Implement that with the respective clock gates and resets to allow the A80 taking part in the DM_MMC game.
