The fiq handler needs access to some register definitions that should not be used directly by device drivers. Since this is closely related to the irqchip driver anyway, move it into the same place. 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 save/restore code is fairly small, so in order to separate the s3c and s5p platforms, adding an s5p specific copy instead of sharing it is actually easier. Signed-off-by:

This is the only part of plat-samsung that is really shared between the s3c and s5p ports. Moving it to drivers/soc/ lets us make them completely independent. Signed-off-by:

The only part of plat-samsung that is shared with arch-exynos is the CPU identification code. Having a separate exynos_cpu_id variable makes the two completely independent and is actually a bit less code in total. 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.

Passing pointers directly as platform data is fragile and undocumented. Better to create a platform data structure which explicitly documents what is passed to the driver. Suggested-by:

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. Make this an indirect function call through platform data instead. Signed-off-by:

Commit f6361c6b ("ARM: S3C24XX: remove separate restart code") removed usage of the watchdog reset platform code in favor of the Samsung SoC watchdog driver. However the latter was not selected thus S3C24xx platforms lost reset abilities. Cc: <stable@vger.kernel.org> Fixes: f6361c6b ("ARM: S3C24XX: remove separate restart code") Signed-off-by:

Krzysztof Kozlowski authored
Similarly to commit f6361c6b ("ARM: S3C24XX: remove separate restart code"), the platform watchdog reset code can be removed in favor of a generic watchdog driver which already handles reset. This allows removal of a bunch of machine code and fixes also W=1 compile warnings: arch/arm/plat-samsung/watchdog-reset.c:29:6: warning: no previous prototype for 'samsung_wdt_reset' [-Wmissing-prototypes] arch/arm/plat-samsung/watchdog-reset.c:69:13: warning: no previous prototype for 'samsung_wdt_reset_of_init' [-Wmissing-prototypes] arch/arm/plat-samsung/watchdog-reset.c:89:13: warning: no previous prototype for 'samsung_wdt_reset_init' [-Wmissing-prototypes] The generic watchdog-based system reset is not exactly the same as before. The previous method had a fallback to soft_restart() which now is gone. The commit also removes a FIXME note about calling s3c64xx_clk_init() inside s3c64xx_init_irq(). No one fixed this since long time and the note is not meaningful anymore because watchdog part is removed. Signed-off-by:

A separate Kconfig option HAVE_S3C2410_WATCHDOG for Samsung SoCs is not really needed and the s3c24xx watchdog driver can depend on Samsung ARM architectures instead. The "HAVE_xxx_WATCHDOG" pattern of dependency is not popular and Samsung platforms are here exceptions. All others just depend on CONFIG_ARCH_xxx. This makes the code slightly smaller without any change in functionality. Signed-off-by:

Remove the arch/arm/plat-samsung/include/plat/samsung-time.h header and move the contents to common.h headers in mach-s3c24xx and mach-s3c64xx.
