2011-09-15ARM: SAMSUNG: fix to prevent declaring duplicatedKukjin Kim1-0/+5
The plat/clock.h revised to prevent declaring duplicated. Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>
2011-09-15ARM: SAMSUNG: fix watchdog reset issue with clk_get()Marek Szyprowski1-0/+3
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 Abraham1-0/+3
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.

2011-01-12ARM: SAMSUNG: Add support for clock debugging through debug-fs interfaceAmit Daniel Kachhap1-0/+3
This patch adds support for clock information exposed to debug-fs interface. Signed-off-by: Amit Daniel Kachhap <amit.daniel@samsung.com> [kgene.kim@samsung.com: removed useless empty lines] Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>

Merge branch 'for-2635/fb-updates1' into for-linus/samsung2
2010-05-18ARM: S3C64XX: Add USB external clock definitionMaurus Cuelenaere1-0/+1
This adds the xusbxti clock to S3C64XX platform. Signed-off-by: Maurus Cuelenaere <mcuelenaere@gmail.com> Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2010-05-10ARM: SAMSUNG: Add s3c_disable_clocks() and tidy init+disable usageBen Dooks1-0/+1
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>
2010-02-20ARM: S3C64XX: Combine the clock init codeBen Dooks1-1/+0
Turn the init sequence of s3c24xx_register_baseclocks(xtal); s3c64xx_register_clocks(); s3c6400_register_clocks(S3C6410_CLKDIV0_ARM_MASK); into a single call as this is now contained within one file. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2010-01-15ARM: S5P6440: Add Clock and PLL supportKukjin Kim1-0/+1
This patch adds clock and pll support for S5P6440. This patch are based on Harald Welte's patches and Ben's plat-samsung. Signed-off-by: Thomas Abraham <thomas.ab@samsung.com> Signed-off-by: Kukjin Kim <kgene.kim@samsung.com> Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2010-01-15ARM: SAMSUNG: Make clk_default_setrate and clk_ops_def_setrate visibleKukjin Kim1-0/+3
This patch makes clk_default_setrate and clk_ops_def_setrate available to code outside plat-samsung clock code. Signed-off-by: Thomas Abraham <thomas.ab@samsung.com> Signed-off-by: Kukjin Kim <kgene.kim@samsung.com> Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2010-01-15ARM: SAMSUNG: Add call to register array of clocksBen Dooks1-0/+2
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 Dooks1-4/+25
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 Dooks1-0/+89
Move the <plat/clock.h> header to plat-samsung where it can be used by all the platforms, and readies it for the next round of clock updates where the clock code will be amalgamated. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
