2012-01-27ARM: SAMSUNG: Fix missing api-change from subsys_interface changeHeiko Stuebner
Commit 4a858cfc9a (arm: convert sysdev_class to a regular subsystem) converted the samsung sysdevs into subsys_interface instances. While the original add-function only had a (struct sys_device *) parameter, the dev_add from subsys_interface needs (struct device *, struct subsys_interface *) leading to "initialized from incompatible pointer type" warnings.

Device tree conversions for samsung and tegra Both platforms had some initial device tree support, but this adds much more to actually make it usable. * tag 'dt' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (45 commits) ARM: dts: Add intial dts file for EXYNOS4210 SoC, SMDKV310 and ORIGEN ARM: EXYNOS: Add Exynos4 device tree enabled board file rtc: rtc-s3c: Add device tree support input: samsung-keypad: Add device tree support ARM: S5PV210: Modify platform data for pl330 driver ARM: S5PC100: Modify platform data for pl330 driver ARM: S5P64x0: Modify platform data for pl330 driver ARM: EXYNOS: Add a alias for pdma clocks ARM: EXYNOS: Limit usage of pl330 device instance to non-dt build ARM: SAMSUNG: Add device tree support for pl330 dma engine wrappers DMA: PL330: Add device tree support ARM: EXYNOS: Modify platform data for pl330 driver DMA: PL330: Infer transfer direction from transfer request instead of platform data DMA: PL330: move filter function into driver serial: samsung: Fix build for non-Exynos4210 devices serial: samsung: add device tree support serial: samsung: merge probe() function from all SoC specific extensions serial: samsung: merge all SoC specific port reset functions ARM: SAMSUNG: register uart clocks to clock lookup list serial: samsung: remove all uses of get_clksrc and set_clksrc ... Fix up fairly trivial conflicts in arch/arm/mach-s3c2440/clock.c and drivers/tty/serial/Kconfig both due to just adding code close to changes.
2011-12-23ARM: SAMSUNG: register uart clocks to clock lookup listThomas Abraham
Samsung uart driver lookups the clock using the connection id 'clk_uart_baud'. The uart clocks for all Samsung platforms are reorganized to register them with the lookup name as required by the uart driver.

2011-12-23ARM: S3C2440: move handling of fclk/n clock to platform codeThomas Abraham
s3c2440 uses fclk/n (fclk divided by n) clock as one of the possible clocks used to generate the baud rate clock. The divider 'n' in this case can be logically represented outside of the uart controller. This patch creates a new clock by name "fclk_n" for s3c2440 based platforms to represent the fclk/n clock in the platform code. This clock provides a get_rate callback that checks the UCON0/1/2 registers to determine the clock rate. The samsung uart driver would receive the "fclk_n" clock name as one of the possible baud rate clock options and the driver need not determine clock rate of fclk/n.

After all sysdev classes are ported to regular driver core entities, the sysdev implementation will be entirely removed from the kernel.

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>
