Hi there, This patchset introduces clock driver support for the Exynos5515 SoC.
Currently, the following CMU blocks are defined: - CMU_TOP (handles clocks for all child CMU blocks) - CMU_PERI (handles clocks for USI, watchdog timer, etc) - CMU_FSYS (handles clocks for MMC, USB, etc) This driver support makes use of HWACG (hardware automatic clock gating), so gates do not need to be manually forced on with CLK_IGNORE_UNUSED or CLK_IS_CRITICAL. Rather, the hardware handles the clock gating. Support for more blocks to come as support for the hardware requiring them is added. I am getting some checkpatch warnings telling me to check the MAINTAINERS file, as new files have been added. I am assuming these can be ignored as I am not a maintainer, and the whole clock driver and samsung subsystems already have maintainers listed.
