Some clocks are required to be unmasked during suspend to RAM. Otherwise the PMU will stuck and the power down sequence will never be completed. Signed-off-by:

Exynos5433 uses different register layout for CPU clock registers than earlier SoCs so add new code for handling this layout. Also add new CLK_CPU_HAS_E5433_REGS_LAYOUT flag to request using it. There should be no functional change resulting from this patch. Cc: Kukjin Kim <kgene@kernel.org> CC: Krzysztof Kozlowski <k.kozlowski@samsung.com> Signed-off-by:

Although unbinding a driver requires root privileges but it still might be used theoretically in certain attacks (by triggering NULL pointer exception or memory corruption if driver does not provide proper remove callbacks or core does not handle it). Samsung clock drivers are essential for system operation so their removal is not expected. More over, the Exynos3250 ISP clock driver does not implement remove() driver callback and it is not buildable as modules. Suppress the unbind interface for Exynos3250 ISP and S3C2410 DCLK clock drivers. Suggested-by:

The PNAME macro defines array of strings for names of mux parents. Although the strings itself were const but pointers to them were not thus this data resided in initdata. Make this an array of const pointers to const strings and move to initconst section. Signed-off-by:
