2009-05-01[ARM] S3C: Make common <plat/dma.h> headerBen Dooks
Move the common information from the <mach/dma.h> header into a new shareable <plat/dma.h> header for re-use on the s3c64xx. Signed-off-by: Ben Dooks <ben@simtec.co.uk> Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2009-04-17[ARM] S3C: Fix sparse warning from missing 's3c_device_hwmon'Ben Dooks
Fix the following sparse warning due to s3c_device_hwmon being missing from <plat/devs.h> devs.c:380:24: warning: symbol 's3c_device_hwmon' was not declared. Should it be static? Signed-off-by: Ben Dooks <ben@simtec.co.uk> Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2009-04-16[ARM] S3C: Export s3c_gpio_cfgpin and s3c_gpio_setpull for modulesBen Dooks
Add an export of the two GPIO configuration calls s3c_gpio_cfgpin and s3c_gpio_setpull to allow modules to use them (such as ASoC drivers) Signed-off-by: Ben Dooks <ben@simtec.co.uk> Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2009-04-07i2c-s3c2410: Simplify bus frequency calculationDaniel Silverstone
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.

2009-04-07i2c-s3c2410: sda_delay should be in ns, not clock ticksBen Dooks
The sda_delay field should be specified in ns, not in clock ticks as when using cpufreq we could be changing the bus rate. Signed-off-by: Ben Dooks <ben@simtec.co.uk>

2009-03-10[ARM] S3C: Tidy sleep code path to fix call flowBen Dooks
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.

2009-03-09ASoC: Fix Samsung S3C2412_IISMOD_SDF_{MSB,LSB} definitionsBen Dooks
The definitions of S3C2412_IISMOD_SDF_MSB and S3C2412_IISMOD_SDF_LSB are incorrect, being the same S3C2412_IISMOD_SDF_IIS which is the only correct one in this series. Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2009-03-08[ARM] S3C: Do not kmalloc/kfree during inner suspend code.Ben Dooks
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 Dooks
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 Dooks
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. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2009-03-08[ARM] S3C: Rename sleep.S functions to be non-cpu specificBen Dooks
Rename s3c2410_cpu_resume to s3c_cpu_resume and s3c2410_cpu_save to s3c_cpu_save to remove the CPU specific naming of these functions which are now in the generic PM code. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2009-03-08[ARM] S3C: Rename s3c2410_pm_init to s3c_pm_init.Ben Dooks
Since we have moved a large proportion of the PM code to the common support area, remove the cpu specific name from the initialisation function. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2009-03-08[ARM] S3C: Make IRQ_EINT sleep control commonBen Dooks
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 Dooks
Fix warnings from struct resource being bigger than unsigned long by forcing the type. We are only a 32bit platform so no physical memory addresses will be too big to fit in this. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2009-03-08[ARM] S3C: Move plat-s3c24xx pm.c support into plat-s3cBen Dooks
Move parts of the core and debug suspend code into the plat-s3c for use with the new s3c64xx code. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2009-03-08[ARM] S3C: Split the resume memory check code from pm.cBen Dooks
Split the optional memory check code out of the pm.c file as it is quite a big #ifdef block and as-such can be moved out and simply compiled when the configuration is set. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2009-03-08[ARM] S3C: Move PM support functions to common locationBen Dooks
Start moving the PM code by moving all the common support functions to a common location in arch/arm/plat-s3c. With the move we rename the functions from s3cxxx_ to s3c_ to fit the new location. Signed-off-by: Ben Dooks <ben-linux@fluff.org>

2009-03-05S3C: Move <mach/audio.h> to <plat/audio.h>Ben Dooks

2008-12-16[ARM] S3C: Add UART FIFO selection during arch decompressionBen Dooks
Add a configuration option to start the UART FIFOs during the decompressions sequence to improve boot time when the bootloader fails to enable the UART FIFOs. For example, the SMDK6410 UBoot 1.1.6 leaves the FIFOs off. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
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. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2008-12-16[ARM] S3C64XX: Update TCFG for new timer divider settings.Ben Dooks
The S3C64XX series has a new TCFG divider setting to allow the clock directly through, which means that we need to update the pwm-clock code to cope with this. Add <mach/pwm-clock.h> containing the specific code to deal with the TCFG divider settings and provide any other per-arch data that the pwm-clock driver needs to function.
