Exynos4210 and Exynos4x12 SoCs have the PL330 MDMA IP block clock defined exactly in same way in documentation. Using different names for these clocks is a bit misleading. Since there is no users of CLK_MDMA2 in existing dts files this patch drops CLK_MDMA2 and replaces it with CLK_MDMA in the driver. This ensures PL330 MDMA has correct clock assigned on Exynos4x12 SoCs. Suggested-by:

Before this patch, the driver was simply zeroing the clock table, which is incorrect, because invalid clock numbers returned NULL instead of error pointers. This patch fixes this by changing the driver to initialize the array with PTR_ERR(-ENOENT). Signed-off-by:

Add support for pll2650xx in samsung pll file. This PLL variant is close to pll36xx but uses CON2 registers instead of CON1. Aud_pll in Exynos5260 is pll2650xx and uses this code. Signed-off-by:

Samsung CCF helper functions do not provide support to register multiple Clock Providers for a given SoC. Due to this limitation, SoC platforms are not able to use these helpers for registering multiple clock providers and are forced to bypass this layer. This layer is modified accordingly to enable the support for multiple clock providers. Clock file for exynos4, exynos5250, exynos5420, exynos5440, S3c64xx, S3c24xx are also modified as per changed helper functions. Signed-off-by:

With the move to the common clock framework completed for s3c2410, s3c2440 and s3c2442, the legacy clock code for these machines can go away too. This also includes the legacy dclk code, as all legacy users are converted. Signed-off-by:

Convert the machines using the s3c2410 to use the new driver based on the common clock framework instead of the legacy Samsung clock driver. As with the s3c244x, machines using the clkout output will need a fixup from someone with the hardware. Signed-off-by:

Convert all machines using these cpus to use the ccf clock driver instead of the legacy Samsung clock implementation. Some of the more esotheric machines will probably need a fixup, as they do strange things to the clkout outputs, that I did not really understand nor have the hardware to check. Signed-off-by:

This adds the necessary init functions to init the clocks from the common clock framework and necessary CONFIG_SAMSUNG_CLOCK ifdefs around the legacy clock code. This also includes empty stubs for the *_setup_clocks functions that are called from the cpufreq driver on resume. Signed-off-by:

This driver can handle the clock controllers of the socs mentioned above, as they share a common clock tree with only small differences. The clock structure is built according to the manuals of the included SoCs and might include changes in comparison to the previous clock structure. As pll-rate-tables only the 12mhz variants are currently included. The original code was wrongly checking for 169mhz xti values [a 0 to much at the end], so the original 16mhz pll table would have never been included and its values are so obscure that I have no possibility to at least check their sane-ness. When using the formula from the manual the resulting frequency is near the table value but still slightly off. Signed-off-by:

Add platform device and select the correct implementation automatically depending on wether the old samsung_clock or the common clock framework is enabled. This is only done for machines already using the old dclk implementation, as everybody else should move to use dt anyway. The machine-specific settings for the external clocks will have to be set by somebody with knowledge about the specific hardware. Signed-off-by:

This adds a driver for controlling the external clock outputs of s3c24xx architectures including the dclk muxes and dividers. The driver at the moment only supports the legacy non-dt boards using these clock outputs. The clock-output control itself is part of the system-controller mainly controlled by the pinctrl drivers. So it should most likely be integrated there for dt platforms. Signed-off-by:

The s3c24xx cpufreq driver needs to change the mpll speed and was doing this by writing raw values from a translation table into the MPLLCON register. Change this to use a regular clk_set_rate call when using the common clock framework and only write the raw value in the samsung_clock case. The s3c cpufreq driver does already aquire the mpll, so simply add a reference to struct s3c_cpufreq_config to let set_fvco access it. While struct clk is opaque the differenciation between samsung clock and common clock is kept, as the samsung-clock mpll clk does not implement a real set_rate. Signed-off-by:

The manuals do not give them explicit names like in later socs, so more generic names with a s3c2410-prefix were used for them. As it was common to do so in the previous implementation, functionality to change the pll rate is already included. Signed-off-by:
