2014-02-28ARM: clps711x: Migrate CLPS711X subarch to the new irqchip driverAlexander Shiyan1-198/+3
This patch remove old code and migrate Cirrus Logic CLPS711X subarch to the new irqchip driver. Signed-off-by: Alexander Shiyan <shc_work@mail.ru> Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2013-11-21ARM: clps711x: Switch to sched_clock_register()Stephen Boyd1-2/+2
The 32 bit sched_clock interface now supports 64 bits. Upgrade to the 64 bit function to allow us to remove the 32 bit registration interface. Cc: Alexander Shiyan <shc_work@mail.ru> Signed-off-by: Stephen Boyd <sboyd@codeaurora.org> Signed-off-by: Kevin Hilman <khilman@linaro.org>

2013-06-11ARM: clps711x: Set PLL clock to zero if we work from 13 mHz sourceAlexander Shiyan1-0/+1
This clock will be used in audio subsystem. Since audio cannot work without PLL we should indicate this. Signed-off-by: Alexander Shiyan <shc_work@mail.ru> Signed-off-by: Olof Johansson <olof@lixom.net>
2012-12-24ARM: delete struct sys_timerStephen Warren1-5/+1
Now that the only field in struct sys_timer is .init, delete the struct, and replace the machine descriptor .timer field with the initialization function itself. This will enable moving timer drivers into drivers/clocksource without having to place a public prototype of each struct sys_timer object into include/linux; the intent is to create a single of_clocksource_init() function that determines which timer driver to initialize by scanning the device dtree, much like the proposed irqchip_init() at: http://www.spinics.net/lists/arm-kernel/msg203686.html Includes mach-omap2 fixes from Igor Grinberg.

2012-11-21ARM: clps711x: Unused empty "ACK" calls for IRQ-chips removedAlexander Shiyan1-10/+0

2012-11-21ARM: clps711x: Add FIQ interrupt handlingAlexander Shiyan1-2/+35
CLPS711X-target CPU can have a several FIQ interrupts. With this patch we adds handling for a one which will be used for ALSA PCM later. Since FIQ have a separate handler we only add "mask" and "unmask" calls which will used for enable/disable_irq functions.

2012-05-15ARM: clps711x: Cleanup IRQ handlingAlexander Shiyan1-12/+0
This patch contains two changes: - Removed unused definitions from mach/irqs.h - Do not mask interrupts in ack procedure, because we have separate intX_mask procedure for do it and actually these 2 functions are called sequentially Signed-off-by: Alexander Shiyan <shc_work@mail.ru> Signed-off-by: Arnd Bergmann <arnd@arndb.de>

2012-03-28Merge tag 'split-asm_system_h-for-linus-20120328' of ↵Linus Torvalds1-0/+1
git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-asm_system Pull "Disintegrate and delete asm/system.h" from David Howells: "Here are a bunch of patches to disintegrate asm/system.h into a set of separate bits to relieve the problem of circular inclusion dependencies. I've built all the working defconfigs from all the arches that I can and made sure that they don't break. The reason for these patches is that I recently encountered a circular dependency problem that came about when I produced some patches to optimise get_order() by rewriting it to use ilog2(). This uses bitops - and on the SH arch asm/bitops.h drags in asm-generic/get_order.h by a circuituous route involving asm/system.h. The main difficulty seems to be asm/system.h. It holds a number of low level bits with no/few dependencies that are commonly used (eg. memory barriers) and a number of bits with more dependencies that aren't used in many places (eg. switch_to()). These patches break asm/system.h up into the following core pieces: (1) asm/barrier.h Move memory barriers here. This already done for MIPS and Alpha. (2) asm/switch_to.h Move switch_to() and related stuff here. (3) asm/exec.h Move arch_align_stack() here. Other process execution related bits could perhaps go here from asm/processor.h. (4) asm/cmpxchg.h Move xchg() and cmpxchg() here as they're full word atomic ops and frequently used by atomic_xchg() and atomic_cmpxchg(). (5) asm/bug.h Move die() and related bits. (6) asm/auxvec.h Move AT_VECTOR_SIZE_ARCH here. Other arch headers are created as needed on a per-arch basis." Fixed up some conflicts from other header file cleanups and moving code around that has happened in the meantime, so David's testing is somewhat weakened by that. We'll find out anything that got broken and fix it.. * tag 'split-asm_system_h-for-linus-20120328' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-asm_system: (38 commits) Delete all instances of asm/system.h Remove all #inclusions of asm/system.h Add #includes needed to permit the removal of asm/system.h Move all declarations of free_initmem() to linux/mm.h Disintegrate asm/system.h for OpenRISC Split arch_align_stack() out from asm-generic/system.h Split the switch_to() wrapper out of asm-generic/system.h Move the asm-generic/system.h xchg() implementation to asm-generic/cmpxchg.h Create asm-generic/barrier.h Make asm-generic/cmpxchg.h #include asm-generic/cmpxchg-local.h Disintegrate asm/system.h for Xtensa Disintegrate asm/system.h for Unicore32 [based on ver #3, changed by gxt] Disintegrate asm/system.h for Tile Disintegrate asm/system.h for Sparc Disintegrate asm/system.h for SH Disintegrate asm/system.h for Score Disintegrate asm/system.h for S390 Disintegrate asm/system.h for PowerPC Disintegrate asm/system.h for PA-RISC Disintegrate asm/system.h for MN10300 ...

2011-11-17ARM: clps711x: consolidate irq/mm/time code into a single fileRussell King1-0/+222
The separate files for clps711x which contain maybe one or two data structures or functions is an inefficient use of files, and encourages further small files as other changes happen. Collapse down these into a single core.c file. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
