2022-04-22ARM: omap1: move mach/*.h into mach directoryArnd Bergmann1-1/+2
Most of the header files are no longer referenced from outside arch/arm/mach-omap1, so move them all to that place directly and change their users to use the new location. The exceptions are: - mach/compress.h is used by the core architecture code - mach/serial.h is used by mach/compress.h The mach/memory.h is empty and gets removed in the process, avoiding the need for CONFIG_NEED_MACH_MEMORY_H.

2021-04-01ARM: omap1: fix building with clang IASArnd Bergmann1-0/+1
The clang integrated assembler fails to build one file with a complex asm instruction: arch/arm/mach-omap1/ams-delta-fiq-handler.S:249:2: error: invalid instruction, any one of the following would fix this: mov r10, #(1 << (((NR_IRQS_LEGACY + 12) - NR_IRQS_LEGACY) % 32)) @ set deferred_fiq bit ^ arch/arm/mach-omap1/ams-delta-fiq-handler.S:249:2: note: instruction requires: armv6t2 mov r10, #(1 << (((NR_IRQS_LEGACY + 12) - NR_IRQS_LEGACY) % 32)) @ set deferred_fiq bit ^ arch/arm/mach-omap1/ams-delta-fiq-handler.S:249:2: note: instruction requires: thumb2 mov r10, #(1 << (((NR_IRQS_LEGACY + 12) - NR_IRQS_LEGACY) % 32)) @ set deferred_fiq bit ^ The problem is that 'NR_IRQS_LEGACY' is not defined here. Apparently gas does not care because we first add and then subtract this number, leading to the immediate value to be the same regardless of the specific definition of NR_IRQS_LEGACY. Neither the way that 'gas' just silently builds this file, nor the way that clang IAS makes nonsensical suggestions for how to fix it is great. Fortunately there is an easy fix, which is to #include the header that contains the definition.

2019-08-13ARM: OMAP1: ams-delta-fiq: Fix missing irq_ackJanusz Krzysztofik1-1/+2
Non-serio path of Amstrad Delta FIQ deferred handler depended on irq_ack() method provided by OMAP GPIO driver. That method has been removed by commit 693de831c6e5 ("gpio: omap: remove irq_ack method"). Remove useless code from the deferred handler and reimplement the missing operation inside the base FIQ handler. Should another dependency - irq_unmask() - be ever removed from the OMAP GPIO driver, WARN once if missing.

Split the header file into two parts and move them to directories where they belong. Information on internal structure of FIQ buffer is moved to <linux/platform_data/ams-delta-fiq.h> for ams-delta-serio driver use. Other information used by ams-delta board init file and FIQ code is made local to mach-omap1 root directory.

2016-06-17ARM: OMAP1: fix ams-delta FIQ handler to work with sparse IRQJanusz Krzysztofik1-3/+3
After OMAP1 IRQ definitions have been changed by commit 685e2d08c54b ("ARM: OMAP1: Change interrupt numbering for sparse IRQ") introduced in v4.2, ams-delta FIQ handler which depends on them no longer works as expected.

2015-05-20ARM: OMAP1: Change interrupt numbering for sparse IRQTony Lindgren1-2/+1
Change interrupt numbering for sparse IRQ. We do this using a fixed offset until we can drop irqs.h once all it's users have been updated. Note that this depends on the GPIO fix for the MPUIO IRQs "gpio: omap: Fix regression for MPUIO interrupts". Also note that this patch adds some extra irq alloc warnings that will go away when we stop calling irq_alloc_descs in gpio-omap.c with a follow-up patch.

2012-03-13ARM: create a common IOMEM definitionRob Herring1-0/+1
Several platforms create IOMEM defines for casting to 'void __iomem *', and other platforms are incorrectly using __io() macro for the same purpose. This creates a common definition and removes all the platform specific versions. Rather than try to make linux/io.h and asm/io.h assembly safe, the assembly version of IOMEM is moved into asm/assembler.h.

2010-05-05OMAP1: Amstrad Delta: add FIQ handler for serial keyboardport interrupt processingJanusz Krzysztofik1-0/+278
This patch introduces a Fast Interrupt Request (FIQ) handler for Amstrad Delta (E3) videophone. The handler's purpose is to process interrupts generated by a GPIO line that a serial keyboard clock hangs off. It collects consecutive bits into words, pushing them into a buffer, then requests a higher level interrupt after one or more words are ready for further processing by a keyboard port driver. The handler also processes interrupts generated by two other GPIO lines, used by other on-board supported devices, by simply requesting a higher level interrupt, that in turn should invoke those device's specific irq handlers. IRQ12 line, not used by OMAP1510 hardware (described as reserved), has been choosen as a higher level interrupt source.
