2013-04-04clk: exynos4: Use mout_mpll_user_* on Exynos4x12Tomasz Figa2-61/+113
Many clock muxes of Exynos 4x12 uses mout_mpll_user_* clocks instead of sclk_mpll as one of their parents. This patch moves such clocks from common array into SoC-specific arrays and adjusts their parent lists respectively.

2013-03-28clk: samsung: add infrastructure to add separate aliasesHeiko Stuebner2-0/+54
The current code adds aliases, if necessary, directly when adding the clock, limiting the number of possible aliases to one. Some platforms need more than one alias, like the hsmmc pclocks on s3c2416 which need a "hsmmc" and "mmc_busclk.0" alias for the s3c- sdhci driver. Therefore add the possibility to separately add clock aliases for previously created clocks.

2013-03-28clk: samsung: register clk_div_tables for divider clocksHeiko Stuebner2-7/+20
On some Samsung platforms divider clocks only use specific divider combinations like the armdiv on s3c2443 and s3c2416. For these usecases the generic divider clock already provides the option of providing a lookup table mapping register values to divider values. Therefore add a new field to samsung_div_clock and if filled with a table, use clk_register_divider_table instead of clk_register_divider to register a divider clock Signed-off-by: Heiko Stuebner <heiko@sntech.de> Reviewed-by: Thomas Abraham <thomas.abraham@linaro.org> Acked-by: Mike Turquette <mturquette@linaro.org> Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>

All Samsung platforms include different types of clock including fixed-rate, mux, divider and gate clock types. There are typically hundreds of such clocks on each of the Samsung platforms. To enable Samsung platforms to register these clocks using the common clock framework, a bunch of utility functions are introduced here which simplify the clock registration process. The clocks are usually statically instantiated and registered with common clock framework.

clocksource_of_init Add entries to __clksrc_of_table so that Exynos MCT controller is discoverable using call to clocksource_of_init. With this change, it would be appropriate to rename the function 'exynos4_timer_init' as 'mct_init' since it aptly describes this function. Additionally, the 'init_time' callback of all machine descriptors for exynos platforms that were previously set to 'exynos4_timer_init' are now set to either 'mct_init' or 'clocksource_of_init'.

Instead of using soc_is_xxx macro at more than one place in the MCT controller driver to decide the MCT interrpt number to be setup, populate a table of known MCT global and local timer interrupts and use the values in table to setup the MCT interrupts. This also helps in adding device tree support for MCT controller driver by allowing the driver to retrieve interrupt numbers from device tree and populating them into this table, thereby supporting both legacy and dt functionality to co-exist.

2013-03-09ARM: EXYNOS: add a register base address variable in mct controller driverThomas Abraham2-88/+62
All the MCT register read/writes use a fixed remapped address S5P_VA_SYSTIMER. With device tree support for MCT controller, it is possible to remove the static remap of the MCT controller address space and do the remap during the initialization of the MCT controller with the physical address obtained from the device tree. So in preparation of adding device tree support for MCT controller, add a new register base address variable that will hold the remapped MCT controller base address and convert all MCT register read/writes to use this new variable as the base address instead of the fixed S5P_VA_SYSTIMER. While at it, the MCT register offset and bit mask definitions are moved into the MCT controller driver file since there are no other consumers of these definitions.
