cpufreq driver for EXYNOS4 based SoCs are not platform drivers, hence we cannot currently pass the clock names through a device tree node. Instead, we need to make them available through a global alias. Clock alias modifications for EXYNOS4 specific clocks are as below. Alias for clock 'arm_clk' is 'armclk'. Alias for clock 'mout_apll' is 'mout_apll'. Alias for clock 'mout_core' is 'moutcore'. For EXYNOS4210, alias for clock 'sclk_mpll' is 'mout_mpll'. For EXYNOS4412, alias for clock 'mout_mpll_user_c' is 'mout_mpll'. Some of the clock aliases are newly defined and some are fixed up. While at it, also modify the debug messages to print the clock values appropriately. Signed-off-by: Tushar Behera <tushar.behera@linaro.org> --- Changes for v2: * Clocks for EXYNOS4X12 has also been modified. * Debug messages are updated to reflect the change in clock alias. * Updated commit message to better describe the changes. drivers/clk/samsung/clk-exynos4.c | 21 +++++++++++---------- 1 file changed, 11 insertions(+), 10 deletions(-)
