2022-06-03ARM: OMAP1: clock: Convert to CCFJanusz Krzysztofik1-0/+5
OMAP1 still uses its own implementation of standard clock API defined in include/linux/clk.h. Internals of that implementation are not visible outside OMAP1 directory. As a consequence, device drivers are not able to register clocks potentially provided by peripheral devices. Drop OMAP1 implementation of the clock API and enable common clock framework. Modify the remaining low level code to be compatible with clock provider API and register the clocks with CCF. Move initialisation of clocks to omap1_timer_init() to avoid memory allocation issues at early setup phase from where omap1_init_early() is called. Register the clocks after initialization of clock I/O registers, local clock pointers used by OMAP1 clock ops, and local .rate fields of clocks with no local implementation of .recalc ops, so CCF structures are populated with correct data during clock registration. Instead of enabling some of the registered clocks, flag them for CCF as critical. Introduce .is_enabled op using code that verifies hardware status of clock enablement, split out from implementation of .disable_unused op, so the latter is actually called by CCF for not requested but hardware enabled clocks. Add .round_rate ops where missing so .set_rate ops are called by CCF as expected. Since CCF allows parallel execution of .enable/.disable and .set_rate ops, protect registers shared among those groups of ops from concurrent access with spinlocks. Drop local debugfs support in favor of that provided by CCF. v2: flag tc2_ck as CLK_IS_CRITICAL (Aaro) v3: rebase on top of soc/omap1-multiplatform-5.18, - drop no longer needed includes from arch/arm/mach-omap1/io.c Signed-off-by: Janusz Krzysztofik <jmkrzyszt@gmail.com> Acked-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2022-04-22ARM: omap1: move mach/*.h into mach directoryArnd Bergmann1-1/+1
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.

2020-03-04ARM: OMAP: replace setup_irq() by request_irq()afzal mohammed1-7/+3
request_irq() is preferred over setup_irq(). Invocations of setup_irq() occur after memory allocators are ready. Per tglx[1], setup_irq() existed in olden days when allocators were not ready by the time early interrupts were initialized. Hence replace setup_irq() by request_irq().

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.

2012-03-28Merge tag 'split-asm_system_h-for-linus-20120328' of ↵Linus Torvalds1-1/+0
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 ...

2011-12-18ARM: 7205/2: sched_clock: allow sched_clock to be selected at runtimeMarc Zyngier1-54/+4
sched_clock() is yet another blocker on the road to the single image. This patch implements an idea by Russell King: http://www.spinics.net/lists/linux-omap/msg49561.html Instead of asking the platform to implement both sched_clock() itself and the rollover callback, simply register a read() function, and let the ARM code care about sched_clock() itself, the conversion to ns and the rollover. sched_clock() uses this read() function as an indirection to the platform code. If the platform doesn't provide a read(), the code falls back to the jiffy counter (just like the default sched_clock). This allow some simplifications and possibly some footprint gain when multiple platforms are compiled in. Among the drawbacks, the removal of the *_fixed_sched_clock optimization which could negatively impact some platforms (sa1100, tegra, versatile and omap). Tested on 11MPCore, OMAP4 and Tegra.

2011-06-20omap: Set separate timer init functions to avoid cpu_is_omap testsTony Lindgren1-3/+3
This is needed for the following patches so we can initialize the rest of the hardware timers later on. As with the init_irq calls, there's no need to do cpu_is_omap calls during the timer init as we only care about the major omap generation. This means that we can initialize the sys_timer with the .timer entries alone. Note that for now we just set stubs for the various sys_timer entries that will get populated in a later patch. The following patches will also remove the omap_dm_timer_init calls and change the init for the rest of the hardware timers to happen with an arch_initcall.

2007-07-21clockevents: fix resume logicThomas Gleixner1-0/+1
We need to make sure, that the clockevent devices are resumed, before the tick is resumed. The current resume logic does not guarantee this. Add CLOCK_EVT_MODE_RESUME and call the set mode functions of the clock event devices before resuming the tick / oneshot functionality. Fixup the existing users. Thanks to Nigel Cunningham for tracking down a long standing thinko, which affected the jinxed VAIO.

2006-07-02[PATCH] ARM: fixup irqflags breakage after ARM genirq mergeThomas Gleixner1-2/+2
The irgflags consolidation did conflict with the ARM to generic IRQ conversion and was not applied for ARM. Fix it up. Use the new IRQF_ constants and remove the SA_INTERRUPT define Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
