[PATCH v7 0/7] rockchip: clk: improve GATE_LINK support

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

I've send this as v7 for the series from Elaine [0], since it kinds of is. These
patches are written from scratch, though. There are two parts:

part 1:
Elaine's series used to contain patches for the VO1GRF handling, but they were
dropped at some point because of the CLK_NR_CLKS feedback from the DT
maintainers. I added some code, that should hopefully fix everyones concerns by
figuring out the right number at runtime. I also moved the correct handling of
pclk_vo0grf/pclk_vo1grf before proper handling of GATE_LINK clocks, so that it
can be merged ASAP. These patches are needed for HDMI RX/TX support on RK3588
and should not be blocked by the GATE_LINK discussion.

part 2:
For proper GATE_LINK support I tried implementing the suggestion from Stephen
Boyd to use clk PM operations by creating MFD dynamically. This required some
restructuring, since CLK_OF_DECLARE() is called before devices are available.
All of this can be found in the last patch of this series.
