2013-09-17ARM: S3C64XX: Remove old clock management codeTomasz Figa
This patch removes old clock management code of S3C64xx, since the platform has been already moved to the new clock driver using Common Clock Framework. Signed-off-by: Tomasz Figa <tomasz.figa@gmail.com> Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>
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.

2012-12-19ARM: S3C64XX: Add I2S clkdev supportPadmavathi Venna
I2S controller has an internal mux for RCLK source clks. The list of source clk names were passed through platform data in non-dt case. Register the existing RCLK source clocks with clkdev using generic connection id. This is required as part of adding DT support for I2S controller driver.

2012-11-08ARM: EXYNOS: Make s3c_device_i2c0 always use id 0Tomasz Figa
This patch removes compatibility definitions added long time ago when clock ids were used instead of devnames that were needed for platforms with only one i2c controller with id -1 (some s3c24xx's). Because currently devname field is used for matching device instances to clocks and if no devname is provided (as in clock-s3c2412.c and common-s3c2443.c for i2c clock, both in arch/arm/mach-s3c24xx) the clock is being matched only by name, so s3c_device_i2c0 can always have id 0. This patch solves the issue with i2c0 broken on boards where its the only i2c controller used, tested on Origen.

2012-07-13spi: s3c64xx: move controller information into driver dataThomas Abraham
Platform data is used to specify controller hardware specific information such as the tx/rx fifo level mask and bit offset of rx fifo level. Such information is not suitable to be supplied from device tree. Instead, it can be moved into the driver data and removed from platform data.

Add entries to clocks_off for some additional clocks which are not currently used by any mainline drivers. They default on at power up but are never actually used so If these blocks are actually supported some of these bindings would need to be redone properly, for example hooking up to the muxes that use them, but that can be done incrementally.

2012-01-27ARM: S3C6410: Use device names for both I2C clocksMark Brown
When the S3C64xx CPUs were converted to clkdev mappings were added for the I2C controllers on them. On S3C6410 a device name is specified for I2C controller 1 but not for controller 0 which makes the code less robust as we'll falsely return the clock for controller 0 if there's an error in the request for controller 1. Improve things by registering a device name for controller 0 as well. Due to the fact that we change the numbering for controller 0 depending on if we've registered controller 1 this requires an ifdef to choose the name.
