Cover letter [PATCH resend v4 0/3] clk: sun6i: Unify AHB1 clock and fix rate calculation
Quoted 9 lines · Chen-Yu Tsai
Hi everyone,
This is a resend of v4 of the sun6i AHB1 clock unification series. This includes only the 3 patches not yet merged.
This series unifies the mux and divider parts of the AHB1 clock found on sun6i and sun8i, while also adding support for the pre-divider on the PLL6 input.
Quoted 8 lines
The rate calculation logic must factor in which parent it is using to calculate the rate, to decide whether to use the pre-divider or not. This is beyond the original factors clk design in sunxi. To avoid feature bloat, this is implemented as a separate composite clk.
The new clock driver is registered with a separate
OF_CLK_DECLARE. As it shares its register with the APB1 div clock, thus shares the same spinlock, it cannot reside in a separate file.
Queued this for 3.20, thanks!
