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.

2009-03-08[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: 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>

2008-12-18[ARM] JIVE: fix spi gpio implementationBen Dooks
Fix the name of the driver, as well as the fact we are not passing the number of chipselects to the driver. 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.

2008-12-15[ARM] S3C: Make i2c device definition common to plat-s3cBen Dooks

2008-12-15[ARM] S3C64XX: Add initial clock frameworkBen Dooks

2008-12-15[ARM] S3C24XX: Update clock data on resumeBen Dooks
Update the clock settings on resume for suspend/resume support so that if the boot loader changes anything or the system's PLL is reset then we return with the correct settings. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2008-12-15[ARM] S3C24XX: Split pll code out of regs-clock.hBen Dooks
Move the PLL calculation code into it's own header file for re-use with the other plat-s3c24xx based systems such as the S3C24A0. Note, we change the name of s3c2410_get_pll to the more generically named s3c24xx_get_pll as well as the related defintions. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2008-12-15[ARM] S3C24XX: Move initialisation code to arch/arm/plat-s3cBen Dooks
We need to add plat-s3c to the build to get the headers that will go in here once moved from include/asm-arm so we may as well put some useful common s3c code in here to stop the errors generated form having nothing built. The cpu setup is now passed the cpu idcode and the table of supported cpus to s3c_init_cpu() to abstract the cpu identification out of the initial io setup. As well as moving the cpu initialisation code, we move the map of the board specific items up to the calling code as none of the map_io() functions actually do anything other than pass this to iotable_init(). This patch does not rename any of the init functions that will be common to s3c24xx and any other s3c architectures as this can be done at a later date as it will touch all the board support files which use functions such as s3c24xx_init_clocks() and s3c24xx_init_uarts(). Note, the header arch/arm/plat-s3c24xx/include/plat/cpu.h still has functions that are used by both the cpu and board initialisation functions. This means that each board has definitions specific to the cpu support included and the vice-versa. Signed-off-by: Ben Dooks <ben-linux@fluff.org>

2008-11-29[ARM] Hide ISA DMA API when ISA_DMA_API is unsetRussell King
When ISA_DMA_API is unset, we're not implementing the ISA DMA API, so there's no point in publishing the prototypes via asm/dma.h, nor including the machine dependent parts of that API. This allows us to remove a lot of mach/dma.h files which don't contain any useful code. Unfortunately though, some platforms put their own private non-ISA definitions into mach/dma.h, so we leave these behind and fix the appropriate #include statments.
