2013-06-17ARM: imx: add VF610 clock supportJingchang Lu
Add clock support for Vybrid VF610. It uses dtc macro support to define all clock IDs in vf610-clock.h to keep clock IDs coherence between kernel and DT. Signed-off-by: Jingchang Lu <b35083@freescale.com> Signed-off-by: Shawn Guo <shawn.guo@linaro.org>

2013-06-17ARM: imx6: use common of_clk_init() call to initialize clocksShawn Guo
Instead of explicitly calling clock initialization functions, we can declare the functions with CLK_OF_DECLARE() and then call common of_clk_init() to have them invoked properly. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>

2013-06-17ARM: i.MX6: clk: add different DualLite MLB clock configDirk Behme
The CCM_CBCMR register (address 0x02C4018) has different meaning between the i.MX6 Quad/Dual and the i.MX6 Solo/DualLite. Compared to the i.MX6 Quad/Dual, the CCM_CBCMR register in the i.MX6 Solo/DualLite reuses the gpu2d_core bits for the MLB clock configuration.

2013-06-17ARM: imx: add clock support for imx6slShawn Guo
Add clock support for i.MX6 SoloLite. It uses the dtc marco support to define all clock IDs in imx6sl-clock.h, which will be included by both clock driver and device tree sources, so that the data will stay sync all the time between kernel and DT. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
2013-06-17ARM: imx: create mxc_arch_reset_init_dt() for DT bootShawn Guo
The mxc_arch_reset_init() uses static mapping and calls clk_get_sys() to get clock. It's suitable for non-DT boot but not for DT boot where dynamic mapping and of_clk_get() should be used instead. Create mxc_arch_reset_init_dt() as the DT variant of mxc_arch_reset_init(), and change DT platforms to use it. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
2013-06-17ARM: imx: move clk_prepare() out from mxc_restart()Shawn Guo
It's inappropriate to call clk_prepare() in mxc_restart(), because the restart routine could be called in atomic context. Move clk_get() and clk_prepare() into mxc_arch_reset_init() and only have the atomic part clk_enable() be called in mxc_restart(). As a result, mxc_arch_reset_init() needs to be called after clk gets initialized. While there, it also changes printk(KERN_ERR ...) to pr_err() and adds __init annotation for mxc_arch_reset_init().

2013-06-17ARM: i.MX6: clk: add i.MX6 DualLite differencesDirk Behme
The CCM_CBCMR register (address 0x02C4018) has different meaning between the i.MX6 Quad/Dual and the i.MX6 Solo/DualLite. Compared to the i.MX6 Quad/Dual, the CCM_CBCMR register in the i.MX6 Solo/DualLite doesn't have a gpu3d_shader configuration and moves the gpu2_core configuration at that place. Handle these i.MX6 Quad/Dual vs. i.MX6 Solo/DualLite clock differences by using cpu_is_mx6dl(). Signed-off-by: Dirk Behme <dirk.behme@de.bosch.com> Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
2013-06-17ARM: i.MX6: add i.MX6 specific L2 cache configurationDirk Behme
To improve the performance and power consumption add an i.MX6 specific L2 cache initialization. This configuration is taken from Freescale's kernel patch "ENGR00153601 [MX6]Adjust L2 cache parameter" [1] with two additional improvements: a) The L2X0_POWER_CTRL has only the two bits we set. So no need to read the register before. Remove the register read done in Freescale's patch. b) In the L2X0_PREFETCH_CTRL register, besides the double linefill (bit[30]), additionally enable the instruction and data prefetch (bit[29-28]).

2013-06-17ARM: i.MX5: Allow DT clock providersMartin Fuzzey
Currently clock providers defined in the DT are not registered on i.MX5 platforms since of_clk_init() is not called. This is not a problem for the SOC's own clocks, which are registered in code, but prevents the DT being used to define clocks for external hardware. Fix this by calling of_clk_init() and actually using the DT to obtain the 4 SOC fixed clocks. These are already defined in the DT but were previously just used to manually obtain the rate. Fall back to the old scheme for non DT platforms. Since the same method may be useful for other i.MX platforms implement the imx_obtain_fixed_clock() function in common code. Actually changing other i.MX platforms to use this should be done later by someone with access to the appropriate hardware.
