2008-12-16[ARM] S3C: Update time initialisation to fix S3C64XX time problemsBen Dooks
The S3C64XX timer is running at the wrong rate due to the assumptions made in the timer initialisation about the way the pwm dividers work. This means that time on the S3C64XX runs twice as fast as it should. Fix the problem by moving to using the clk framework to setup the pwm timer clock muxes, as the pwm-clock code has all the necessary knowledge of how the timer clock inputs are routed.

2008-12-15[ARM] S3C6400: Register clk_fout_epllBen Dooks
The clk_fout_epll clock wasn't registered as part of the initial clock work, which can cause problems if it is used by one of the hardware blocks. Signed-off-by: Ben Dooks <ben-linux@fluff.org>

2008-12-15[ARM] S3C: Add GPIO chip trackingBen Dooks
The gpiolib driver keeps its chip array to itself and having a separate array for s3c-only gpios stops any non-s3c gpio being used in one of the s3c specific configuration calls. Signed-off-by: Ben Dooks <ben-linux@fluff.org>

2008-12-15[ARM] S3C64XX: Reduce some output from INFO to DEBUGBen Dooks
Some of the startup output can be reduced to KERN_DEBUG from KERN_INFO as it is only really useful when trying to debug kernel initialisation problems. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2008-12-15[ARM] S3C64XX: Add IRQ_EINT supportBen Dooks
Add the necessary code to support IRQ_EINT(x) on the S3C64XX series of CPUs. Note, since there is no GPIO configuration support in the kernel, the irq set_type method does not configure the relevant pin to interrupt. Signed-off-by: Ben Dooks <ben-linux@fluff.org>

2008-12-15[ARM] S3C64XX: Initial arch header filesBen Dooks
Add the initial header files for the S3C64XX support to satisfy the minimal requirements to build a kernel.
