2010-02-22ARM: S3C64XX: Eliminate plat-s3c64xxBen Dooks
Now we've move the support out of plat-s3c64xx for everything, eliminate the platform directory arch/arm/plat-s3c64xx and remove it from the ARM build configuration. Note, PLAT_S3C64XX is kept around for the moment until the drivers that depend on it can be updated, so it is moved to the mach-s3c64xx Kconfig. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
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.

2010-02-20ARM: S3C64XX: Remove plat-s3c64xx Kconfig and PLAT_S3C64XXBen Dooks
Remove the Kconfig and PLAT_S3C64XX defines for the previous S3C64XX directory structure now that the code is moved into mach-s3c64xx. Note, we cannot currently remove plat-s3c64xx directory as we have a pair of include files used within plat-s3c and plat-samsung that need to find a new home.

2010-02-20ARM: S3C64XX: Merge s3c6400-clock.c and clock.c into mach-s3c64xxBen Dooks
Merge plat-s3c64xx/s3c6400-clock.c mach-s3c64xx/clock.c placing all the clock code into one place. Note, no effort is made in this patch to squash the init functions together. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2010-02-20ARM: S3C64XX: Merge s3c6400-init.c into cpu.cBen Dooks
Since this file is small, and is compiled for both systems in this architecture merge it into the cpu support file and remove the original instead of moving it. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2010-02-20ARM: S3C64XX: Move core support to mach-s3c64xxBen Dooks
Move the core S3C64XX support to mach-s3c64xx as it is unlikely to be used outside of this directory. Also move the SoC header files in with it. This includes the clock, cpu, cpufreq, dma, gpiolib and pll support. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2010-02-20ARM: S3C64XX: Move device and device setup into mach-s3c64xxBen Dooks
Move the S3C64XX specific device and setup files into mach-s3c64xx as they are unlikely to be used outside of this code. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2010-02-20ARM: S3C64XX: Move IRQ support into mach-s3c64xxBen Dooks

2010-02-20ARM: S3C64XX: Move headers into machine include directoryBen Dooks
Move the register and GPIO definition files from plat-s3c64xx into the machine include direcotry as they are unlikely to be reused outside mach-s3c64xx. This move includes removing the empty <mach/regs-clock.h> and replacing it with the <plat/regs-clock.h> implementation. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2010-01-21ARM: S3C64XX: Tidy up common code in s3c64xx_spi_set_info()Ben Dooks
The s3c64xx_spi_set_info() sets one of two platform data structures depending on which controller is being specified. Change to taking a pointer to the relevant platform data structure and then having one set of code to place the data into the area being pointed to.

2010-01-18ARM: S3C64XX: SPI: Header for passing platform dataJassi Brar
We need a way to pass controller specific information to the SPI driver. For that purpose new headers are made. SPI Controller is assumed 'type-s3c64xx' and can be defined for newer SoCs. Hence, that part is placed under plat-samsung to be shared across newer SoCs.

2010-01-15ARM: Add common entry code for system with two VICsBen Dooks
Add a common entry-macro-vic2.S for systems where there are two VICs so that the machine or platform directories just need to setup the correct information before including <asm/entry-macro-vic2.S> into their own entry-macro.S file. Since this code is from the S3C64XX project, we update the S3C64XX machine entry code to use this new header. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2010-01-15ARM: SAMSUNG: Move IRQ UART handling for newer devices to plat-samsungBen Dooks

2010-01-15ARM: SAMSUNG: Move IRQ VIC timer handling out to common header filesBen Dooks
Move the VIC based timer interrupt handling out of plat-s3c64xx and into plat-samsung to be re-used for other systems. This also reduces the code size as we now have a common init routine and use the irq_desc to store the interrupt number of the timer. Signed-off-by: Ben Dooks <ben-linux@fluff.org>

2010-01-15ARM: S3C64XX: Avoid announcing clksrc clocks twiceBen Dooks
The new code calls the clock setup code on registration which can be before the clock system has been fully initialised. The following code re-does this setup at the end of the clock registration and thus we get two printings. Update the calls to only print on the last pass or when doing the necessary resume work.

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>

Move the s3c6400-clock.c implementation over to use the new common plat-samsung based clock-clksrc.c. Note, this does not delete the clocks definitions that are now unused in the regs-clock.h to reduce the quantity of change in this commit. Based on original patches by Harald Welte.

2010-01-15ARM: S3C64XX: Compress s3c6400-clock.c codeBen Dooks
The individually named clocks are all static to the code and thus can be compressed into a single array and then the array can be referenced. This removes the need for a seperate array of pointers to clocks. Fix a minor problem of re-initialising the pointers in s3c6400_set_clksrc() as this is also called by the cpufreq code. Move these initialisations to the code that does the registration. Based on Harald Welte's original clock changes patch. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2010-01-15ARM: S3C64XX: Cleanup common init code in s3c6400-clock.cBen Dooks
Remove the four fields from clksrc_clk.clk which are always the same and init them when the clock is registered. This helps remove the amount of repeated code. This is a re-work of Harald Welte's clock changes for the latest kernel. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2010-01-07ARM: S3C64XX: Fix possible clock look in EPLL and MPLL clock chainsBen Dooks
There is a possibility of a loop happening in the PLL output clock chain on the S3C64XX series. clk_mpll's parent was set to be clk_mout_mpll, but this is fed from clk_fout_epll (which is also clk_mpll). clk_mpll is meant to be the output from the MPLL, and clk_mout_mpll is a seperate clock derived from the mux of clk_mpll and clk_fin_mpll and thus should be considered a seperate clock. Anything using clk_mpll directly really should not be relying on this being the clock that is eventually routed to a peripheral, so remove the loop and ensure that the clocks accurately represent the clock chain in the device. The clk_mpll is not being used outside of the s3c6400-clock.c code, so this change should not break anything else. Do the same for the EPLL. Signed-off-by: Ben Dooks <ben-linux@fluff.org>

2009-12-01ARM: S3C64XX: Redo voltage ranges for cpufreqMark Brown
The documentation for the S3C6410 CPU voltage scaling is rather unclear, with omitted values for several speed settings. Originally the code was using only quoted values, resulting in some fairly odd settings. The S3C6410 is also unusual in that the both the maximum and minimum voltages quoted scale as the frequency rises, rather than just the minimum voltage. Clean this up a bit by always using the specified typical settings as the minimum voltage (ignoring any specified minimum voltage) in order to avoid running near the edge of the processor capabilities. Also use the next quoted maximum voltages rather than the typical voltages where no maximum voltage is quoted, allowing operation on a greater range of systems.

2009-12-01ARM: S3C64XX: Separate out regulator and frequency latenciesMark Brown
Currently the transition latency reported by the S3C64xx cpufreq driver includes both the time for the CPU to reclock itself and the time for a regulator to change voltage. This means that if a regulator is not in use then the transition latency reported is excessively high. In future the regulator API will be extended to report latencies so the driver will be able to query the performance of a given regulator.
