2011-08-29ARM: mach-shmobile: sh7372 CMT3 and CMT4 clock supportMagnus Damm1-1/+5
Add clock control support for sh7372 CMT hardware blocks. No upstream sh7372 boards are making use of CMT3 + CMT4, but the sh7372 hardware happens to come out of reset with all CMT MSTP clocks _enabled_, so to save power we need to implement a fix in software to shut down unused clocks. This patch relies on the recently merged 794d78f drivers: sh: late disabling of clocks V2 to make sure the unused clocks get disabled as expected.

2011-08-24ARM: mach-shmobile: sh7372 LCDC1 suspend fixMagnus Damm1-0/+2
Associate the HDMI clock together with LCDC1 on sh7372. Without this patch Suspend-to-RAM hangs on the boards AP4EVB and Mackerel. The code hangs in the LCDC driver where the software is waiting forever for the hardware to power down. By explicitly associating the HDMI clock with LCDC1 we can make sure the HDMI clock is enabled using Runtime PM whenever the driver is accessing the hardware. This HDMI and LCDC1 dependency is documented in the sh7372 data sheet. Older kernels did work as expected but the recently merged (3.1-rc) 794d78f drivers: sh: late disabling of clocks V2 introduced code to turn off clocks lacking software reference which happens to include the HDMI clock that is needed by LCDC1 to operate as expected.

2011-07-11ARM: mach-shmobile: Use CMT2 for timer on sh7372Magnus Damm1-4/+4
Switch the sh7372 CPU support to use CMT2 instead of CMT1 for system timer. CMT1 is located in the A3SP power domain while CMT2 is located in the always-on power domain C5. This improves our PM situation - with CMT2 as timer we can power down A3SP and still access the timer. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2011-05-24ARM: mach-shmobile: Disable sh7372 RT side MSTP bitsMagnus Damm1-0/+12
Update the sh7372 clock code to set the RT side set of MSTP bits to a fixed disabled state. The sh7372 SoC contains two sets of MSTP bits, one for the ARM (SYS) side, and one for the SH4AL-DSP (RT) side. The actual clock associated with the MSTP bit will only be stopped when both sides have set the MSTP bit to disabled mode. Some MSTP bits are enabled by default after hardware reset, so this patch adjusts the code to disable all MSTP bits associated with the RT side to allow the SYS side to have full control.

2010-11-24ARM: mach-shmobile: clock-sh7372: remove bogus pllc2 clock toggling.Kuninori Morimoto1-10/+2
The PLLC2 clock was utilizing the same sort of enable/disable without regard to usecount approach that the FSIDIV clock was when being used as a PLL pass-through. This forces the enable/disable through the clock framework, which now prevents the clock from being ripped out or modified underneath users that have an existing handle on it.
