Hi,
I've been running a couple of builds for a patch that I'm working on and I noticed the following errors happening for all Exynos boards:
arch/arm/cpu/armv7/exynos/clock.c: In function 'clock_get_periph_rate': arch/arm/cpu/armv7/exynos/clock.c:263:47: warning: array subscript is above array bounds [-Warray-bounds] struct clk_bit_info *bit_info = &clk_bit_info[peripheral]; ^ The problem seems to be that clock_get_periph_rate() is called with the PERIPH_ID_PWM0 parameter in get_pwm_clk(). clock_get_periph_rate() in turn calls exynos5_get_periph_rate() which uses the peripheral parameter to index into the clk_bit_info array. However, PERIPH_ID_PWM0 seems to evaluate to 132, but the clk_bit_info contains only 29 elements.
I don't know how to properly fix this, but perhaps the clk_bit_info table needs to be extended to cover other clocks?
