| | | | | | | | Add definitions for the EINT group registers and move the EINT IRQ register definitions out of arch/arm/plat-s3c64xx/irq-eint.c so that they are available for re-use with PM and the other code. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
* [ARM] S3C64XX: Add modem registers and a virtual mapBen Dooks2009-03-102-0/+36
| | | | | | | | | Add the modem registers and a virtual mapping for the modem block. This is is required as there are registers that control the LCD block that need to be saved over suspend as well as interrupt controls. Signed-off-by: Ben Dooks <ben-linux@fluff.org>

| | | | | | | | | | | | | | | | | | | | Currently the unmask function for EINT interrupts was setting the mask bit rather than clearing it.

| | | | | | | | | | | | | | | | | | | | | | Some of the rate selection logic in s3c64xx_setrate_clksrc uses what appears to be parent clock selection logic. This patch corrects it. I also added a check for overly large dividers to prevent them from changing unrelated clocks. Signed-off-by: Werner Almesberger <werner@openmoko.org> Signed-off-by: Ben Dooks <ben-linux@fluff.org>

* | [ARM] S3C64XX: Do gpiolib configuration earlierMark Brown2009-02-261-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | arch_initcall() runs after the machine init function which means that any configuration of GPIO pins must currently be done later on, for example in callbacks from drivers. Move the initialisation earlier in order to allow machines to configure GPIOs directly in their init functions rather than having to have a callback invoked later on. Some other ARM platforms use this method. Other solutions for this include providing a special interface for setting up GPIOs en masse, adding callbacks to do the GPIO configuration from devices and doing the GPIO configuration implicitly.

| | | | | | | | | | | | | | | | | | | | | | | | | | 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.
