| * ARM: S3C2443: Further clksrc-clk conversionsBen Dooks2010-03-07
| | | | | | | | | | | | | | | | 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>
| * ARM: S3C2443: Change to using plat-samsung clksrc-clk implementationBen Dooks2010-03-07
| | | | | | | | | | | | | | | | | | 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).

| * | ARM: SAMSUNG: Remove dma-plat.h to allow plat-s3c64xx to be removedBen Dooks2010-02-21
| |/ | | | | | | | | | | | | | | | | | | | | | | 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.

* ARM: SAMSUNG: Add call to register array of clocksBen Dooks2010-01-15

* ARM: SAMSUNG: Reduce size of struct clk.Ben Dooks2010-01-15
| | | | | | | | | | | | | | | 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>

* | [ARM] S3C: Update time initialisation to fix S3C64XX time problemsBen Dooks2008-12-16
|/ | | | | | | | | | | | | 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>
* [ARM] S3C64XX: Add initial clock frameworkBen Dooks2008-12-15

* [ARM] S3C24XX: Move initialisation code to arch/arm/plat-s3cBen Dooks2008-12-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* | [ARM] Hide ISA DMA API when ISA_DMA_API is unsetRussell King2008-11-29
|/ | | | | | | | | | | | | 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.
