Also some related cleanups were done prior to that. More specifically: - patches #1..5: cleanups - patch #6: PM code extraction During the extraction of the exynos5433_cmu_probe() content to exynos_arm64_register_cmu_pm() some code was reworked a bit, and also split into smaller functions. In particular: - cmu_data structure now contains a pointer to ctx, which is now allocated in samsung_clk_init() - cmu_data structure initialization was moved into separate function - code for configuring gate clocks was added (optional) Which in turn resulted in somehow modified code of probe function: Original -------- ... devm_platform_ioremap_resource(...); samsung_clk_init(...); exynos_arm64_cmu_prepare_pm(...); exynos_arm64_enable_bus_clk(...); platform_set_drvdata(...); ... Modified -------- ... platform_set_drvdata(...); exynos_arm64_cmu_prepare_pm(...); exynos_arm64_enable_bus_clk(...); exynos_arm64_init_clocks(...); devm_platform_ioremap_resource(...); samsung_clk_init(...); ... That shouldn't really change the logic or mode of operation. It was preliminary tested on Exynos850 based board, with some extra patches on top of this series (will be submitted later). Changes in v3: - Rebased on the most recent soc/for-next tree - Added A-b tags from Marek - Added Marek's authorship to clk-exynos-arm64.c Changes in v2: - Rebased all patches on top of the latest soc/for-next tree - Added Tested-by tag from Marek - Addressed comments from the review Sam Protsenko (6): clk: samsung: Don't pass reg_base to samsung_clk_register_pll() clk: samsung: Remove np argument from samsung_clk_init() clk: samsung: Set dev in samsung_clk_init() clk: samsung: Extract clocks registration to common function clk: samsung: Extract parent clock enabling to common function clk: samsung: exynos5433: Extract PM support to common ARM64 layer drivers/clk/samsung/clk-exynos-arm64.c | 220 +++++++++++++++++++++-- drivers/clk/samsung/clk-exynos-arm64.h | 3 + drivers/clk/samsung/clk-exynos4.c | 6 +- drivers/clk/samsung/clk-exynos4412-isp.c | 3 +- drivers/clk/samsung/clk-exynos5250.c | 5 +- drivers/clk/samsung/clk-exynos5420.c | 5 +- drivers/clk/samsung/clk-exynos5433.c | 157 +--------------- drivers/clk/samsung/clk-pll.c | 11 +- drivers/clk/samsung/clk-s3c64xx.c | 4 +- drivers/clk/samsung/clk-s5pv210.c | 6 +- drivers/clk/samsung/clk.c | 64 ++++--- drivers/clk/samsung/clk.h | 10 +- 12 files changed, 276 insertions(+), 218 deletions(-)
