2013-08-12ARM: SAMSUNG: Remove pwm-clock infrastructureTomasz Figa
Since all the used PWM prescalers and dividers configuration has been moved to appropriate drivers, the pwm-clock infrastructure is now unused and so this patch removes it.

2013-07-24ARM: S3C24XX: Add missing clkdev entries for s3c2440 UARTSylwester Nawrocki
This patch restores serial port operation which has been broken since commit 60e93575476f ("serial: samsung: enable clock before clearing pending interrupts during init") That commit only uncovered the real issue which was missing clkdev entries for the "uart" clocks on S3C2440. It went unnoticed so far because return value of clk API calls were not being checked at all in the samsung serial port driver. This patch should be backported to at least 3.10 stable kernel, since the serial port has not been working on s3c2440 since 3.10-rc5.

2012-03-07ARM: S3C24XX: remove XXX_setup_clocks method from S3C2443Heiko Stuebner
s3c2443_common_setup_clocks is always called through s3c2443_common_init_clocks, so there is no need to call it separately. It was also called twice through this separate call. Signed-off-by: Heiko Stuebner <heiko@sntech.de> Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>
2012-01-31ARM: S3C2410: move s3c2410_baseclk_add to clock.hHeiko Stuebner
plat-samsung/clock.h currently keeps all the SoC specific clock declarations. As we want to get rid of s3c2410.h altogether, move the s3c2410_baseclk_add there too. Signed-off-by: Heiko Stuebner <heiko@sntech.de> Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>
2012-01-31ARM: S3C24XX: move common S3C2443 clock definitions to clock.hHeiko Stuebner
plat-samsung/clock.h currently keeps all the SoC specific clock declarations except the ones for S3C2443/S3C2416 which were kept in s3c2443.h. This patch moves them out of s3c2443.h to get rid of the header completely later on. Signed-off-by: Heiko Stuebner <heiko@sntech.de> Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>

2011-09-15ARM: SAMSUNG: fix watchdog reset issue with clk_get()Marek Szyprowski
clkdev framework uses global mutex to protect clock tree, so it is not possible to call clk_get() in interrupt context. This patch fixes this issue and makes system reset by watchdog call working again.

2011-07-20ARM: SAMSUNG: Add clkdev infrastructureThomas Abraham
The struct clk definition for Samsung platforms is extended to include a instance of struct clk_lookup and a device name. When clocks are registered using s3c24xx_register_clock function, the dev_id, con_id and clk members are initialized with information from the struct clk instance and struct clk_lookup member is registered.

2010-05-10ARM: SAMSUNG: Add s3c_disable_clocks() and tidy init+disable usageBen Dooks
Add s3c_disable_clocks() and change the clock registration code to use the s3c_register_clocks() followed by s3c_disable_clocks() instead of the loops it was using. Signed-off-by: Ben Dooks <ben-linux@fluff.org>

2010-01-15ARM: SAMSUNG: Add call to register array of clocksBen Dooks
Add s3c_register_clocks() to register an array of clocks, printing an error message if there is a problem. Replace all points in the code where this could be used. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2010-01-15ARM: SAMSUNG: Reduce size of struct clk.Ben Dooks
Reduce the size of struct clk by 12 bytes and make defining clocks with common implementation functions easier by moving the set_rate, get_rate, round_rate and set_parent calls into a new structure called 'struct clk_ops' and using that instead. This change does make a few clocks larger as they need their own clk_ops, but this is outweighed by the number of clocks with either no ops or having a common set of ops. Update all the users of this. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2010-01-15ARM: SAMSUNG: Move <plat/clock.h> to plat-samsungBen Dooks
