[PATCH v3 0/3] ARM: da850: fix pll0 rate setting

While trying to set the pll0 rate from the kernel I noticed there are two issues with da850 clocks. The first patch fixes an infinite loop in propagate_rate(). The third fixes an oops in da850_set_pll0rate(). The second patch is just a coding style fix, while we're at it. v1 -> v2: - change the ap

[PATCH v3 3/3] ARM: da850: fix da850_set_pll0rate()

This function is confusing - its second argument is an index to the freq table, not the requested clock rate in Hz, but it's used as the set_rate callback for the pll0 clock. It leads to an oops when the caller doesn't know the internals and passes the rate in Hz as argument instead of the cpufreq

[PATCH v3 1/3] ARM: da850: fix infinite loop in clk_set_rate()

The aemif clock is added twice to the lookup table in da850.c. This breaks the children list of pll0_sysclk3 as we're using the same list links in struct clk. When calling clk_set_rate(), we get stuck in propagate_rate(). Create a separate clock for nand, inheriting the rate of the aemif clock and
