In order to prepare for PM enablement in clk-exynos850, common PM code
was extracted from clk-exynos5433 to clk-exynos-arm64. 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).
Marek, could you please test these patches on Exynos5433 platform, and
also review accordingly?
Thanks!
