* clk: samsung: Add compile time PLL rate validatorsAndrzej Hajda2018-02-231-10/+10
| | | | | | | | | | | | | | | | | | | | Rates declared in PLL rate tables should match exactly rates calculated from PLL coefficients. To avoid possible mistakes we can use compile time validation. The patch introduces such validators and expands all initializers with additional input frequency parameter, required to validate rates. Since S3C24xx PLLs requires different validators two new macros have been introduced to deal with it. Also, since PLLs 4502 and 4508 have different formulas PLL_45XX_RATE has been replaced with PLL_4508_RATE. As the patch adds only compile time validators it should not have impact on compiled code.

* clk: samsung: Add support for EPLL on exynos5410Sylwester Nawrocki2016-09-091-2/+28
| | | | | | | | | | | | | | | This patch adds code instantiating the EPLL, which is used as the audio subsystem's root clock. The requirement to specify the external root clock in clocks property is documented. Having the consumer 'clocks' property ensures proper initialization order by explicitly specifying dependencies in DT. It prevents situations when the SoC's clock controller driver has initialized, the external oscillator clock is not yet registered and setting clock frequencies through assigned-clock-rates property doesn't work properly due to unknown external oscillator frequency.

* clk: samsung: Properly include clk.h and clkdev.hStephen Boyd2015-07-201-2/+0
| | | | | | | | | | | | | | Clock provider drivers generally shouldn't include clk.h because it's the consumer API. Only include clk.h in files that are using it. The clkdev.h header isn't always used either, so remove it and add in slab.h where files were relying on it to include slab for them.

* clk: samsung: Register clk provider only after registering its all clocksSylwester Nawrocki2014-06-301-0/+2
| | | | | | | | | | Ensure the clock provider is not registered until after all its related clocks were created and are ready to use. Currently there are races possible and any (of_)clk_get() call right after a clock provider's clk_init_cb callback call may fail.
