The move is necessary to support early debug output on exynos with multiplatform configurations. This implies also moving the plat/debug-macro.S file, but we are leaving the remaining users of that file in place, to avoid adding large numbers of extra configuration options to Kconfig.debug Signed-off-by: NArnd Bergmann <arnd@arndb.de>

The registers for the Samsung S3C serial port are currently defined in the platform specific arch/arm/plat-samsung/include/plat/regs-serial.h file, which is not visible to multiplatform capable drivers. Unfortunately, it is not possible to move the file into a more local place as we should normally try to, because the same registers may be used in one of four places: * In the driver itself * In platform-independent ARM code for early debug output * In platform_data definitions * In the Samsung platform power management code I have also found no way to logically split out a platform_data file, other than possibly move everything into include/linux/platform_data, which also felt wrong. The only part of this file that makes sense to keep specific to the s3c24xx platform are the virtual and physical addresses defined here, which are needed in no other location.

Due to NR_IRQS being incorrectly defined not all IRQ domains can be registered for S3C2440. It causes following errors on a s3c2440 SoC based board: NR_IRQS:89 S3C2440: IRQ Support irq: clearing pending status 00000002 ------------[ cut here ]------------ WARNING: at kernel/irq/irqdomain.c:234 0xc0056ed0() ... irq: could not create irq-domain ... s3c2410-wdt s3c2410-wdt: failed to install irq (-22) s3c2410-wdt: probe of s3c2410-wdt failed with error -22 ... samsung-uart s3c2440-uart.0: cannot get irq 74 Fix this by increasing NR_IRQS to at least (IRQ_S3C2443_AC97 + 1) if CPU_S3C2440 is selected, so the subintc IRQ domain gets properly registered.

The Kconfig entry for SMDK2440_CPU2442 was moved from one Kconfig file to another in commit acf2d41d ("ARM: S3C24XX: Move mach-s3c2440/ pll into mach-s3c24xx/"). In that move it also lost its statement to select CPU_S3C2442. That was not needed anymore because it now depended on that same symbol. But without its select this entry became a nop: enabling it has no effect, as it changes no code. It can safely be removed. Fix a related, and trivial, comment typo too.

This removes the dependency on static irq mappings for basic irq handling and makes the s3c24xx entry-macro.S obsolete. Also the interrupts of the second full interrupt controller on the s3c2416 are really handled now, which was forgotten when adding them. The handling itself does the same as the previous assembler-code in that it tries to get the interrupt offset from the offset register first and if that produces wrong results manually searches for the interrupt bit in the pending register value. It also saves the historic comment which explains the reason behind this. Signed-off-by: NHeiko Stuebner <heiko@sntech.de> Signed-off-by: NKukjin Kim <kgene.kim@samsung.com>

The s3c24xx_init_irq function that was the base for all irq inits is now only used to initialize the real s3c2410 irqs.

The current parent_irq check checks for a value != 0. This does of course not work when the parent irq sits in the bit 0 of the parent register. This only affects the eint0 interrupt of the s3c2412. To fix this behaviour, check for the presence of a parent_intc in the structure. In an s3c24xx interrupt controller either all interrupts have parent interrupts or none have, so if a parent controller is available the parent_irq value always points to a parent_irq.

The check during the parent handling itself was wrong, as it should have checked for parent_irq_data. The interrupt controller structs always contain an irq_data array with 32 entries and the only possible error could be a parent_irq assignment of >31. As this would point to outside the irq_data array this could contain anything including non-NULL values. Therefore correct this to check the parent_irq value to be in the right range. With the same explanation of a valid interrupt controller always having a full irq_data array, the topmost irq_data check in s3c24xx_irq_map can also go away. Finally the mapping function is only called thru the irq_domain ops, in which case the intc struct is already successfully created, so there is no need to check for it again.

The s3c2412 handles the eints 0 to 3 different than all the other SoCs of the 24xx range. These eints must be acked and masked in the regular bits as well as the bits 0 to 3 of the eint registers, which are unused on the other SoCs. This of course can be realized using the new infrastructure with the eint bits in the main register being the parent interrupts of the same bits in the eint register. The s3c2412 therefore gets its own IRQ_EINT0 to 4 constants that reside in the newly created gap before IRQ_EINT4. gpio-samsung, as the only user of these is modified to return the correct values when handling gpio_to_irq requests on s3c2412 based machines. Due to lack of hardware this is compile tested only, but should hopefully work as intended. Signed-off-by: NHeiko Stuebner <heiko@sntech.de> Signed-off-by: NKukjin Kim <kgene.kim@samsung.com>

This patch moves the irq numbers starting with EINT4 4 points down to enable the inclusion of the first 4 bits of EINT register into the mapping removing the need for special offset handling. For most S3C24XX architectures this will simply create 4 additional unused interrupts, but enables the S3C2412 to make use of the new infrastructure to realize its special handling of the EINT0 to EINT3 interrupts. All affected parts of the Samsung code (arch + drivers) seem to use the real interrupt defines (IRQ_something) and not any form of S3C2410_IRQ(x) whose numbering is changed here starting from S3C2410_IRQ(32).
