2013-04-28clocksource: samsung_pwm_timer: Let platforms select the driverTomasz Figa1-1/+1
This patch modifies the way of enabling the driver to let the platforms select it in their Kconfig instead of specifying particular platforms in Kconfig entry of the driver.

2013-04-26ARM: arch_timer: Silence debug preempt warningsStephen Boyd1-4/+6
Hot-plugging with CONFIG_DEBUG_PREEMPT=y on a device with arm architected timers causes a slew of "using smp_processor_id() in preemptible" warnings: BUG: using smp_processor_id() in preemptible [00000000] code: sh/111 caller is arch_timer_cpu_notify+0x14/0xc8 This happens because sometimes the cpu notifier, arch_timer_cpu_notify(), is called in preemptible context and other times in non-preemptible context but we use this_cpu_ptr() to retrieve the clockevent in all cases. We're only going to actually use the pointer in non-preemptible context though, so push the this_cpu_ptr() access down into the cases to force the checks to occur only in non-preemptible contexts.

2013-04-21clocksource: add samsung pwm timer driverTomasz Figa3-0/+488
This adds a new clocksource driver for the PWM timer that is present in most Samsung SoCs, based on the existing driver in arch/arm/plat-samsung/samsung-time.c and many changes implemented by Tomasz Figa. Originally, the conversion of all Samsung machines to the new driver was planned for 3.10, but that work ended up being too late and too invasive just before the merge window. Unfortunately, other changes in the Exynos platform resulted in some Exynos4 setups, particularly the Universal C210 board to be broken. In order to fix that with minimum risk, so we now leave the existing pwm clocksource driver in place for all older platforms and use the new driver only for device tree enabled boards. This way, we can get the broken machines running again using DT descriptions. All clocksource changes were implemented by Tomasz, while the DT registration was rewritten by Arnd.

2013-04-19clocksource: exynos_mct: remove platform header dependencyArnd Bergmann1-15/+6
For the non-DT case, the mct_init() function requires access to a couple of platform specific constants, but cannot include the header files in case we are building for multiplatform. This changes the interface to the platform so we pass all the necessary data as arguments to mct_init.

2013-04-19clocksource: exynos_mct: fix build error on non-DTArnd Bergmann1-0/+4
There is currently no alternative implementation for of_irq_count when the function is not defined, and the declaration is hidden, so this works around calling an undeclared function. It should really not be needed. Signed-off-by: Arnd Bergmann <[email protected]>

2013-04-11ARM: convert arm/arm64 arch timer to use CLKSRC_OF initRob Herring2-14/+10
This converts arm and arm64 to use CLKSRC_OF DT based initialization for the arch timer. A new function arch_timer_arch_init is added to allow for arch specific setup. This has a side effect of enabling sched_clock on omap5 and exynos5. There should not be any reason not to use the arch timers for sched_clock.

2013-04-08clocksource: sunxi: Rename sunxi to sun4iMaxime Ripard3-19/+19
During the introduction of the Allwinner SoC platforms, sunxi was initially meant as a generic name for all the variants of the Allwinner SoC. It was ok at the time of the support of only the A10 and A13 that looks pretty much the same, but it's beginning to be troublesome with the future addition of the Allwinner A31 (sun6i) that is quite different, and would introduce some weird logic, where sunxi would actually mean in some case sun4i and sun5i but without sun6i... Moreover, it makes the compatible strings naming scheme not consistent with other architectures, where usually for this kind of compability, we just use the oldest SoC name that has this IP, so let's do just this.

2013-03-13clocksource: sh_mtu2: Set initcall level to subsysSimon Horman1-1/+1
The reason for this is to ensure that MTU2 is probed earlier than with its previous initcall level, module init. This came up as a problem with using CMT as a clock source kzm9g-reference which does not make use of early timers or devices. In that scenario initialisation of SDHI and MMCIF both stall on msleep() calls due to the absence of a initialised clock source. The purpose of this change is to keep the MTU2 code in sync with the CMT code which has been modified in a similar manner.. Compile tested only using se7206_defconfig. I do not believe I have any boards that support the MTU2. Signed-off-by: Simon Horman <[email protected]>
2013-03-13clocksource: em_sti: Set initcall level to subsysSimon Horman1-1/+12
The reason for this is to ensure that STI is probed earlier than with its previous initcall level, module init. This came up as a problem with using CMT as a clock source kzm9g-reference which does not make use of early timers or devices. In that scenario initialisation of SDHI and MMCIF both stall on msleep() calls due to the absence of a initialised clock source. The purpose of this change is to keep the STI code in sync with the CMT code which has been modified in a similar manner.. Boot tested on: kzm9d. Signed-off-by: Simon Horman <[email protected]>

2013-03-13clocksource: sh_cmt: Add CMT register layout commentMagnus Damm1-0/+15
Add a comment about different register layouts supported by the CMT driver. Signed-off-by: Magnus Damm <[email protected]> Acked-by: John Stultz <[email protected]> Tested-by: Guennadi Liakhovetski <[email protected]> Signed-off-by: Simon Horman <[email protected]>
2013-03-13clocksource: sh_cmt: Add control register callbacksMagnus Damm1-4/+12
This patch adds control register callbacks for the CMT driver. At this point only 16-bit access is supported but in the future this will be updated to allow 32-bit access as well.

2013-03-13clocksource: sh_cmt: CMCNT and CMCOR register access updateMagnus Damm1-36/+26
Break out the CMCNT and CMCOR register access code into separate 16-bit and 32-bit functions that are hooked into callbacks at init time. This reduces the amount of software calculations happening at runtime.

2013-03-13clocksource: sh_cmt: CMSTR and CMCSR register access updateMagnus Damm1-36/+30
Update hardware register access code for CMSTR and CMCSR from using sh_cmt_read() and sh_cmt_write() to make use of 16-bit register access functions such as sh_cmt_read16() and sh_cmt_write16(). Also update sh_cmt_read() and sh_cmt_write() now when the special cases are gone. This patch moves us one step closer to the goal of separating counter register access functions from control control register functions.

Introduce sh_cmt_read_cmstr/cmcsr/cmcnt() and sh_cmt_write_cmstr/cmcsr/cmcnt/cmcor() to in the future allow us to split counter registers from control registers and reduce code complexity by removing sh_cmt_read() and sh_cmt_write().
