2009-05-18[ARM] S3C64XX: Use common watchdog reset for system reset.Ben Dooks1-0/+1

2009-05-18[ARM] S3C: Move watchdog system reset to own file.Ben Dooks1-0/+48
Move the watchdog reset code from <mach/system-reset.h> to a new file <plat/watchdog-reset.h> as this code is needed by both s3c2410, s3c64xx and soon-to-be added s3c24a0. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2009-05-17[ARM] S3C: ADC: Expose number of remaining conversions toNelson Castillo1-1/+2
convert callback This patch allow us to efficiently modify the number of remaining conversions from the client side. This us useful when we do not know in advance how many conversions we will need or when we need to cancel pending conversions. This change is simple enough to be compatible with existing code that can just define the new pointer in the callback and ignore it.

2009-05-15[ARM] S3C: Do not set clk->owner field if unsetBen Dooks1-2/+0
The s3c24xx_register_clock() function has been doing a test on clk->owner to see if it is NULL, and then setting itself as the owner if clk->owner == NULL. This is not needed, arch/arm/plat-s3c/clock.c cannot be compiled as a module, and even if it was, it should not be playing with this field if it being registered from somewhere else. The best course of action is to remove this bit of code completely. Signed-off-by: Ben Dooks <ben-linux@fluff.org>

2009-05-07[ARM] S3C64XX: Add S3C6400 SDHCI setup supportBen Dooks1-5/+45
Add support for S3C6400 SDHCI channels 0 and 1, making the GPIO code common to both S3C6400 and S3C6410. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2009-05-07[ARM] S3C: GPIO PM core GPIOlib integrationBen Dooks4-1/+421
Move the GPIO suspend/resume support inline with the gpiolib support so that it will work with both the S3C24XX and S3C64XX series. The s3c_gpio_chip is extended to have a pm callback and a save block to keep the state of the GPIO over suspend, and the code from the s3c24xx implementation is added to a new common file. The suspend process now uses the list of registered chips to go through saving and restoring each one as appropriate, using the pm callback to select the appropriate routine depending on the type of control register present. This change also means that any additional GPIO added should not require changes to the PM. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2009-05-07[ARM] S3C64XX: Add IRQ PM codeBen Dooks1-0/+5
Add support for saving the state of the IRQ registers over suspend. This requires moving the S3C64XX UART registers into <plat/regs-serial.h> and adding irq-pm.c which saves the state of all the IRQ registers. The irq-pm.c saves all the IRQ registers, including the IRQ_EINT and IRQ_EINT_GROUP registers as it was easier than adding three different files. Also ensuring that all the registers are restored to the same state as before suspend is considered to be the best thing to do. Note, we do not suspend the VIC here, this is done by the VIC driver itself. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2009-05-07[ARM] S3C64XX: Add generic s3c64xx sys device.Ben Dooks1-0/+2
Add an s3c64xx_sysclass and device for items that currently want to bind to any s3c64xx processor. The first user of this will be parts of the s3c64xx suspend support which need to save device state over suspend/resume. Signed-off-by: Ben Dooks <ben-linux@fluff.org>

2009-04-07i2c-s3c2410: Simplify bus frequency calculationDaniel Silverstone3-20/+23
The platform data for the i2c-s3c2410 driver used to allow a min, max and desired frequency for the I2C bus. This patch reduces it to simply a desired frequency ceiling and corrects all the uses of the platform data appropriately. This means, for example, that on a system with a 66MHz fclk, a request for 100KHz will achieve 65KHz which is safe and acceptable, rather than 378KHz which it would have achieved without this change.

2009-03-10[ARM] S3C: Tidy sleep code path to fix call flowBen Dooks2-9/+19
As noted by Russell King, the sleep code path is not elegant and makes use of leaving items on the stack between calls. Change the code that does the following: if (s3c_cpu_save(regs_save) == 0) { flush_cache_all(); S3C_PMDBG("preparing to sleep\n"); pm_cpu_sleep(); } to simply call s3c_cpu_save, and let that do the necessary calls to quiesce and sleep the system.

2009-03-08[ARM] S3C: Do not kmalloc/kfree during inner suspend code.Ben Dooks3-8/+33
The PM CRC checking code kmallocs an area to save a set of CRC values during suspend. This triggers a warning due to the call of a function that might sleep whilst the system is not in a valid state to do so. Move the allocation and free to points in the suspend and resume process where they can call a function that might-sleep. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2009-03-08[ARM] S3C: Avoid checking the task stackpage in pm-checkBen Dooks1-1/+9
When doing the CRC check of the memory, avoid checking the page that our stack is residing in as this changes during the execution of the suspend and resume. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2009-03-08[ARM] S3C: Update UART save over PM suspend/resumeBen Dooks2-22/+58
Change the way the UART state is saved over suspend to allow the s3c64xx code to modify the settings on resume to avoid any illegal state changes to the UART clocks. This will also allow us to save the UDIVSLOT register on newer SoCs. Move to using a structure for the UART use the extant Kconfig configuration specifying the number of UARTs.

2009-03-08[ARM] S3C: Rename sleep.S functions to be non-cpu specificBen Dooks2-3/+5

Move the IRQ_EINT sleep control to be available to all s3c impelmentations. Since s3c_irqext_wake is not large, place it in arch/arm/plat-s3c/pm.c as adding it to a new file would be a waste of compile time. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2009-03-08[ARM] S3C: Fix warnings in the PM memory CRC codeBen Dooks1-2/+4
