2010-03-07ARM: Merge next-samsung-s3c2443-clockBen Dooks
Merge branch 'next-samsung-s3c2443-clock' into next-samsung
2010-03-07ARM: S3C2443: Add set_rate and round_rate calls for armdiv clockBen Dooks
Add set_rate and round_rate calls to armdiv for future use with cpu frequency scaling. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2010-03-07ARM: S3C2443: Remove #if 0 for clk_mpllBen Dooks
The clk_mpll has long been moved into common clock code, remove the code completely instead of the nasty #if 0 block. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2010-03-07ARM: S3C2443: Update notes on MPLLREF clockBen Dooks
Add note on MPLLREF clock source and why it cannot be easily removed. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2010-03-07ARM: S3C2443: Further clksrc-clk conversionsBen Dooks
Move more of the core clocks that where left over from the last commit as they are much more core to the system operation. This should allow for easier tracking of any problems. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2010-03-07ARM: S3C2443: Change to using plat-samsung clksrc-clk implementationBen Dooks
The S3C2443 clock code could easily make use of the clksrc implementation in plat-samsung for many of the clocks. Make the clocks that easily move to clksrc-clk over, update any initialisation and remove the old register definitions from the header file (it is only being used once).

2010-02-24ARM: SMDK2443: Enable AC97 deviceJassi Brar

2010-02-22ARM: Merge next-samsung-s3c64xx-platdeletionBen Dooks
Merge branch 'next-samsung-s3c64xx-platdeletion' into next-samsung Conflicts: arch/arm/mach-s3c64xx/Makefile (fixed)
2010-02-21ARM: SAMSUNG: Remove dma-plat.h to allow plat-s3c64xx to be removedBen Dooks
dma-plat.h is the last file left in plat-s3c64xx, but to remove it we must also change the use of dma-plat.h by the core code and the s3c24xx implementation. Rename the s3c24xx dma-plat.h in the common plat-samsung directory as it may be used for other ports. Move the specific dma bits into the mach-s3c64xx directory and update the build as needed. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2010-02-01ARM: S3C244X: Merge plat-s3c24xx s3c2440.h and s3c2442.h into s3c244x.hBen Dooks
Merge these two headers into one, these two SoCs are so similar. Note, correct fault in mach-smdk2443.h including the wrong header. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2010-01-30ARM: S3C2443: Use common clock gate codeBen Dooks
Add common clock gate code for each of the S3C2443 clock gate code. Whether to move this elsewhere will be decided later. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2010-01-15ARM: SAMSUNG: Add call to register array of clocksBen Dooks
Add s3c_register_clocks() to register an array of clocks, printing an error message if there is a problem. Replace all points in the code where this could be used. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2010-01-15ARM: SAMSUNG: Reduce size of struct clk.Ben Dooks
Reduce the size of struct clk by 12 bytes and make defining clocks with common implementation functions easier by moving the set_rate, get_rate, round_rate and set_parent calls into a new structure called 'struct clk_ops' and using that instead. This change does make a few clocks larger as they need their own clk_ops, but this is outweighed by the number of clocks with either no ops or having a common set of ops. Update all the users of this. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2009-11-09Kconfig: Remove useless and sometimes wrong commentsMichael Roth
Additionally, some excessive newlines removed. Signed-off-by: Michael Roth <mroth@nessie.de> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
2009-05-01[ARM] S3C24XX: DMA: Split hardware regs out of <mach/dma.h>Ben Dooks
The <mach/dma.h> is for the driver API for the DMA system and should not have anything relying on the CPU specific registers. Remove the registers to <plat/dma-regs.h> for the code that really needs to know about them. Signed-off-by: Ben Dooks <ben@simtec.co.uk> Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2009-05-01[ARM] S3C24XX: Move plat/dma.hBen Dooks

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: 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.
