* ARM: S3C24XX: Move s3c2443-clock.c to mach-s3c24xxHeiko Stuebner2012-03-031-635/+0
| | | | | | | | | S3C-SoCs starting with the S3C2443 can share a lot of functionality. The file can collect more common code of these SocS later on and therefore gets a new name to reflect this future purpose.

* ARM: S3C24XX: move common S3C2443 clock definitions to clock.hHeiko Stuebner2012-01-311-1/+0
| | | | | | | | | | | | 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>
* ARM: SAMSUNG: Add lookup of sdhci-s3c clocks using generic namesRajeshwari Shinde2011-12-231-6/+10
| | | | | | | | | Add support for lookup of sdhci-s3c controller clocks using generic names for s3c2416, s3c64xx, s5pc100, s5pv210 and exynos4 SoC's.

* ARM: SAMSUNG: register uart clocks to clock lookup listThomas Abraham2011-12-231-7/+16
| | | | | | | | | | 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.

* ARM: S3C24XX: Add devname for hsmmc1 pclkHeiko Stuebner2011-10-141-0/+1
| | | | | | | | | | | | S3C2443 uses hsmmc1 as its only hsmmc device and for S3C2416/S3C2450 it's the second hsmmc channel with the same PCLKCON bit. The hsmmc-if clocks on both systems already got a devname, as did the hsmmc pclk for hsmmc0 on the S3C2416. So to make it possible to identify the hsmmc1 pclk on S3C2416 add the correct devname for it. The sclk name on S3C2443 also is s3c-sdhci.1.

* ARM: S3C24XX: use clk_get_rate to init fclk in common_setup_clocksHeiko Stuebner2011-10-141-5/+3
| | | | | | | | | | | | | Previously the fclk rate was calculated by dividing the pll through the divider value of the armdiv. With a real armdiv clk in place it's possible to simply read its value, which does essentially the same. This change makes the whole fdiv_fn function pointers supplied to s3c2443_common_init_clocks and s3c2443_common_setup_clocks obsolete, so remove it too.

* ARM: S3C2443: Accommodate cpufreq frequency scheme in armdivHeiko Stuebner2011-10-141-2/+4
| | | | | | | | | | | | | Cpufreq uses frequencies in kHz and not Hz, so set_rate and round_rate would be called with a frequency of 266666000 instead of 266666666 but the clock functions check for rates smaller or equal to the targetrate. As the armdiv does not support steps this small we can accommodate this by simply also setting the last 3 digits of the calculated rate to zero.

* ARM: S3C2443: handle unset armdiv values gracefullyHeiko Stuebner2011-10-141-7/+20
| | | | | | | | | | The armdiv array may contain unset divider values. Check the relevant value to prevent division by zero errors. Also check for set nr_armdiv and armdivmask before meddling with clkdiv0. Signed-off-by: Heiko Stuebner <heiko@sntech.de> Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>

* ARM: S3C2443: Move clk_arm and clk_armdiv to common codeHeiko St?bner2011-10-141-0/+87
| | | | | | | | | | The system-layout of the armdiv and armclk is common to S3C2443/S3C2416/S3C2450 and only differs in the array of possible dividers. Therefore it is possible to reuse the clock definitions for all of these SoCs. Signed-off-by: Heiko Stuebner <heiko@sntech.de> Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>

* ARM: S3C24XX: Add address map and clock definitions for HSMMC0Yauhen Kharuzhy2011-01-061-1/+1
| | | | | | | | | | | | | | Define maps for HSMMC devices. S3C2443 has one HSMMC device with base address 0x4A800000. S3C2416 has HSMMC0 at 0x4AC00000 and HSMMC1 at 0x4A800000. So suppose that S3C2443 has only HSMMC1. Define clock for hsmmc0 device and register it. Signed-off-by: Yauhen Kharuzhy <jekhor@gmail.com> Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>
* ARM: S3C2443: Move parts of the clock code to common clock fileBen Dooks2010-05-101-0/+472
To share code with some of the newer parts such as the S3C2416, move parts of arch/arm/mach-s3c2443/clock.c to a common file called arch/arm/plat-s3c24xx/s3c2443-clock.c. Update the build configuration to deal with this new file. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
