Marek Szyprowski a98fcb2fc1 clk: samsung: exynos4: mark 'chipid' clock as CLK_IGNORE_UNUSED ... [ Upstream commit f3bb0f796f ] The ChipID IO region has it's own clock, which is being disabled while scanning for unused clocks. It turned out that some CPU hotplug, CPU idle or even SOC firmware code depends on the reads from that area. Fix the mysterious hang caused by entering deep CPU idle state by ignoring the 'chipid' clock during unused clocks scan, as there are no direct clients for it which will keep it enabled.
