[PATCH v1 01/04] clk: actions: Add Actions Semi S500 SoC clock support

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

 



Add Actions Semi S500 SoC clock support.
Basic clock support for S500 SoC was implemented using the Actions
Semi Owl clock driver.
Tested on a Lemaker Guitar board.

This patch depends on patch "[PATCH v6 1/5] clk: actions: Add missing
REGMAP_MMIO dependency" by Saravanan Sekar.
This patch depends on patch "[PATCH] clk: actions: Add custom delay
option to Actions Semi OWL pll clock driver" by Edgar Bernardi Righi.
