The gen2_clk_get_sdh_div() function is supposed to look up the $val value read out of the SDCKCR register in the supplied table and return the matching divider value. The current implementation was matching the value from SDCKCR on the divider value in the table, which is wrong. Fix this and rework the function a bit to make it more readable.

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

2018-12-06clk: Allow clock defaults to be set during re-reloc state for SPL onlyPhilipp Tomsich
In commit e5e06b65ad65 ("clk: Allow clock defaults to be set also during re-reloc state") the earlier guard against setting clock defaults in pre-reloc state was removed. While it is easy to filter 'assigned-clocks' properties for SPL using CONFIG_OF_SPL_REMOVE_PROPS, no such mechanism exists for the pre-reloc stage of the full U-Boot. With the default defconfig for the RK3399-Q7 (which filter the 'assigned-clocks' property for the DTS used by SPL anyway), this caused a pause during startup of the full U-Boot stage that lasted for almost 10s (due to the CPU not having been clocked up yet). This reintroduces the guard from commit f4fcba5c5baa ("clk: Allow clock defaults to be set also during re-reloc state") and extends it to only apply outside of a TPL/SPL build: i.e. clk_set_defaults will now run in pre-reloc state for SPL, but only after reloc for the full U-Boot.
