PWM timer initialization has two independent implementations - one for S3C24xx and one for S3C64xx. The naming however was always the same and before also the declaration was shared. This is confusing, error prone and might cause issues when trying to build multiplatform kernel. Suggested-by:

s3c24xx and s3c64xx have a lot in common, but are split across three separate directories, which makes the interaction of the header files more complicated than necessary. Move all three directories into a new mach-s3c, with a minimal set of changes to each file. Signed-off-by:

A number of other files rely on mach/map.h to be indirectly included from mach/io.h through mach/hardware.h. Reduce this to the minimal plat/map-base.h and add explicit includes everywhere else. Signed-off-by:

Rather than have the cpufreq drivers touch include the common headers to get the constants, add a small indirection. This is still not the proper way that would do this through the common clk API, but it lets us kill off the header file usage. Signed-off-by:

There are two identical copies of the s3c2412_cpufreq_setrefresh function: a static one in the cpufreq driver and a global version in iotiming-s3c2412.c. As the function requires the use of a hardcoded register address from a header that we want to not be visible to drivers, just move the existing global function and add a declaration in one of the cpufreq header files.

The cpufreq drivers are split between the machine directory and the drivers/cpufreq directory. In order to share header files after we convert s3c to multiplatform, those headers have to live in a different global location. Move them to linux/soc/samsung/ in lack of a better place. Signed-off-by:

Each of the cpufreq drivers uses a fixed set of register bits, copy those definitions into the drivers to avoid including mach/regs-clock.h. [krzk: Fix build by copying also S3C2410_LOCKTIME] Signed-off-by:

The s3c2410fb driver is too deeply intertwined with the s3c24xx platform code. Change it in a way that avoids the use of platform header files but having all interface data in a platform_data header, and the private register definitions next to the driver itself. One ugly bit here is that the driver pokes directly into gpio registers, which are owned by another driver. Passing the mapped addresses in platform_data is somewhat suboptimal, but it is a small improvement over the previous version. Signed-off-by:

Once we move to sparse irqs, the irq_desc[] array is no longer accessible, so replace the two uses in bast-irq.c. The first one can use irq_to_desc(), the second one seems completely unneeded as we already have a pointer to the correct descriptor. Signed-off-by:

The IRQ_EINT0 constant is a platform detail that is defined in mach/irqs.h and not visible to drivers once that header is made private. Since the same calculation already happens in s3c24xx_set_fiq, just return the value from there. Signed-off-by:

Rather than call the internal s3c_gpio_cfgall_range() function through a platform header, move the code into the set_power callback that is already exported by the board, and add a default implementation. In DT mode, the code already does not set the pin config, so nothing changes there. Signed-off-by:

The s3c_gpio_cfgall_range() function is an internal interface of the samsung gpio driver and should not be called directly by drivers, so move the iis pin initialization into the boards. This means the pin configuration is only run once at early boot, rather than each time the driver binds, but the effect should be the same. Note that the s3c2412-i2s driver has no boards using it in mainline linux, the driver gets selected for the jive machine but is never instantiated. Signed-off-by:

There are multiple drivers using the private adc interface. It seems unlikely that they would ever get converted to iio, so make the current state official by making the header file global. The s3c2410_ts driver needs a couple of register definitions as well. Signed-off-by:

It was a good idea to move it out at first, but the irqchip code is still tightly connected to the s3c24xx platform code and uses multiple internal header files, so just move it back for the time being to avoid those dependencies. Signed-off-by:

The pm-debug code is one of the few things shared between s3c24xx/s3c64xx and the newer s5pv210. In order to make s5pv210 independent of plat-samsung, change the common bits of this code to no longer reference the s3c specific bits. In particular, all the CPU checks need to be moved out of the common code into platform specific files. Signed-off-by:

On s3c24xx and s3c64xx, this is just a wrapper around s3c_pm_debug_init_uart(), but this function does not exist on s5pv210, which always uses an empty stub as CONFIG_SAMSUNG_ATAGS is normally not set. In a configuration that supports both s5pv210 and s3c64xx, we would always call the s3c64xx function, which is probably incorrect when running on s5pv210. Remove the function call completely on s5pv210 and skip the wrapper on s3c as a cleanup. As a side-effect, the s3c64xx behavior is now always the same, regardless of whether it is a DT-only configuration or both DT and ATAGS are supported for booting. Signed-off-by:

There is no real phy driver, so s3c-hsudc just pokes the registers itself. Improve this a little by making it a platform data callback like we do for gpios. There is only one board using this driver, and it's unlikely that another would be added, so this is a minimal workaround. Signed-off-by:

s3c24xx has a custom implementation of the inb/outb family of I/O accessors, implementing both general register access and ISA I/O port through a multiplexer. As far as I can tell, the first case has never been needed, and certainly is not used now, as drivers only use inb/outb to actually driver ISA or PCI port I/O. Similarly, the special ISA support is limited to a single machine, the Simtec Electronics BAST (EB2410ITX) with its PC/104 expansion connector, all other machines could simply use the generic implementation from asm/io.h that expects a single memory-mapped address range for byte, word and dword access. As no other machines besides BAST actually selects CONFIG_ISA, this is likely not even necessary. As a cleanup, remove support for the non-ISA access from the helpers, and make the ISA access use the virtual address window that we use elsewhere for PCI I/O ports. In configurations without the BAST machine, this now falls back on the generic implementation from asm/io.h, but the mach/io.h header is still relied on to include a number of other header files implicitly.

The clk driver uses both a function call into an exported platform file and a direct register access to a hardcoded virtual address for accessing the MISCCR register, both become are a problem for a multiplatform kernel because of the header file dependency.
