Hi everyone,
Here is an attempt at improving the MMC clock support in the Allwinner
SoCs.
Until now, the MMC clocks were having a custom phase function that was
directly setting an obscure value in the right register, because we
were not really having any idea of what these values were.
Now that we have more informations, we can introduce a common function
call to get and set the phase of a particular clock, and use this in
both our provider and our client.
Thanks,
Maxime
Changes from v2:
- Reworked the get_phase operation handling to call it from
_clk_init instead of the ugly hack
- Added the clocks to the A23
- Modified the output and sample clock names to have a consistent
naming
Changes from v1:
- Dropped the patches to enforce rate boundaries on the clocks. This
is partly covered by the Tomeu, and should be based on this
whenever it will be merged.
- Fixed a few typos here and there
- Added a patch to include of.h from clk-provider.h
Maxime Ripard (11):
clk: Include of.h in clock-provider.h

clk: sunxi: factors: Invert the probing logic
clk: sunxi: Introduce mbus compatible
ARM: sunxi: dt: Switch to the new mbus compatible
clk: sunxi: Move mod0 clock to a file of its own
clk: sunxi: Move mbus to mod0 file
ARM: sunxi: dt: Add sample and output mmc clocks
clk: sunxi: mod0: Introduce MMC proper phase handling
mmc: sunxi: Convert MMC driver to the standard clock phase API
clk: sunxi: Remove custom phase function
Mike Turquette (1):
clk: introduce clk_set_phase function & callback
