2009-03-04S3C64XX: Initial support for CPU frequency scalingMark Brown
This patch provides initial support for CPU frequency scaling on the Samsung S3C64XX series processors. Currently only S3C6410 processors are supported, though addition of another data table with supported clock rates should be sufficient to enable support for further CPUs. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2009-03-04S3C64XX: Add initial support for ARMCLKMark Brown
Add support for reconfiguring the clock for the ARM core, enabling CPUfreq support. Currently only the divider for ARMCLK may be changed, ARMPLL is left static. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2009-03-04S3C: CPU detection supportKyungmin Park

GTA03 project is dropped, long live Openmoko 3d7k project. This name was literally generated by picking the first character of the next four car license plates to pass by I am told. The should catch all GTA03 instances except the machine name. I registered a new machine name since the 3d7k is different from original GTA03, the machine number is 2120.

2009-03-02OpenMoko: Update for normal WM8753 device registration.Mark Brown
The WM8753 driver now uses the standard I2C device registration model and so requires the platform to register the device. Convert the OpenMoko GTA0x series devices to do so. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2009-03-02ARM/S3C2440: Don't build armv4t modules we can't loadRask Ingemann Lambertsen
The kernel can't load armv4t modules ("unknown relocation: 40"). This patch fixes the ARM makefile accordingly to tell GCC to generate armv4 code instead of armv4t code. The assembler still needs to allow armv4t instructions for some object files which are linked into the kernel. Signed-off-by: Rask Ingemann Lambertsen <rask@sygehus.dk>

2009-02-25clean-neo1973-pm-gps.patchAndy Green
Clean out more switch() on version that has no point given the actual features that (don't) differ on supported GTA02 versions. We take care about forcing GPS regulator off on neo1973-pm-gps probe, but we don't take care about killing the UART GPIO so they don't drive into the powered-down subsystem. We took care of doing that when we turned off the thing already, but we cannot just call the OFF code from the probe due to problems with regulator state init.

2009-02-23fix-pm-gsm-disable-serial-drive-when-off.patchAndy Green
This patch cleans some cruft from neo1973-pm-gsm.c and makes some changes to the power code for gsm. First, on probe it enforces GSM is OFF. Second, when GSM is OFF, it changes the RTS and TXD pins on UART 0 to be inputs, instead of driving into a dead subsystem and costing us ~70mA @ 5V constant dissipation (these 3.3V pins were found at 1.5V due to that). Third it asserts the GPIO peripheral function when ON, to keep the same flow for the new interrupt generation workaround code. Since several people worked on this area before, and maybe the assertion of GSM OFF is different (it's OFF from bootloader though) or maybe something else gets broken, I send the patch for comment before applying it.
