| | | | | | | | | | | | | | | | | | | | | | | | | | | The SH73A0 SoC has sparse GPIO numbers. Declare the pin numbers ranges in the PFC SoC data and use the pin numbers in the GPIO API.

There are both new drivers as well as existing drivers that are getting converted from platform-specific code into standalone drivers using the appropriate subsystem specific interfaces. In particular, we can now have pinctrl, clk, clksource and irqchip drivers in one file per driver, without the need to call into platform specific interface, or to get called from platform specific code, as long as all information about the hardware is provided through a device tree. Most of the drivers we touch this time are for clocksource. Since now most of them are part of drivers/clocksource, I expect that we won't have to touch these again from arm-soc and can let the clocksource maintainers take care of these in the future. Another larger part of this series is specific to the exynos platform, which is seeing some significant effort in upstreaming and modernization of its device drivers this time around, which unfortunately is also the cause for the churn and a lot of the merge conflicts. There is one new subsystem that gets merged as part of this series: the reset controller interface, which is a very simple interface for taking devices on the SoC out of reset or back into reset. Patches to use this interface on i.MX follow later in this merge window, and we are going to have other platforms (at least tegra and sirf) get converted in 3.11. This will let us get rid of platform specific callbacks in a number of platform independent device drivers." * tag 'drivers-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (256 commits) irqchip: s3c24xx: add missing __init annotations ARM: dts: Disable the RTC by default on exynos5 clk: exynos5250: Fix parent clock for sclk_mmc{0,1,2,3} ARM: exynos: restore mach/regs-clock.h for exynos5 clocksource: exynos_mct: fix build error on non-DT pinctrl: vt8500: wmt: Fix checking return value of pinctrl_register() irqchip: vt8500: Convert arch-vt8500 to new irqchip infrastructure reset: NULL deref on allocation failure reset: Add reset controller API dt: describe base reset signal binding ARM: EXYNOS: Add arm-pmu DT binding for exynos421x ARM: EXYNOS: Add arm-pmu DT binding for exynos5250 ARM: EXYNOS: Enable PMUs for exynos4 irqchip: exynos-combiner: Correct combined IRQs for exynos4 irqchip: exynos-combiner: Add set_irq_affinity function for combiner_irq ARM: EXYNOS: fix compilation error introduced due to common clock migration clk: exynos5250: Fix divider values for sclk_mmc{0,1,2,3} clk: exynos4: export clocks required for fimc-is clk: samsung: Fix compilation error clk: tegra: fix enum tegra114_clk to match binding ...
| * | ARM: shmobile: INTC External IRQ pin driver on r8a7779Magnus Damm2013-03-18

The r8a7779 SoC can like older SH SoCs configure to use the IRQ0 -> IRQ3 signals as individual interrupts or a combined IRL mode. Without this patch the r8a7779 SoC code does not fully support external IRQ pins in individual IRQ mode. The r8a7779 PFC code does not yet have gpio_to_irq() support so no need to update such code. At this point the DT reference implementations are not covered. In the future such code shall tie in the INTC External IRQ pin driver via DT, so this kind of verbose code is not needed for the long term DT case.

It is a cleaner approach if every CPU takes care of its own flags. We avoid the need for locking and the program logic is more concise. With this patch the file headsmp-sh73a0.S is added that contains a startup vector for secondary CPUs that sets up its own SCU flags. Further in sh73a0_smp_prepare_cpus() we can rely on the generic ARM helper scu_power_mode(). This is possible as we don't cross borders anymore (every CPU handles its own flags) and need no locking.

* ARM: shmobile: mark shmobile_init_late as __initArnd Bergmann2012-10-09
| | | | | | | | | | | | | | | | | | | | Patch 35f2b0bd59 "ARM: shmobile: Move definition of shmobile_init_late() to header" moved the definition of the shmobile_init_late function, but dropped the __init annotation, which is now causing warnings because the function calls shmobile_suspend_init, which is also marked init. Without this patch, building kota2_defconfig results in: WARNING: vmlinux.o(.text+0xb7c8): Section mismatch in reference from the function shmobile_init_late() to the function .init.text:shmobile_suspend_init() The function shmobile_init_late() references the function __init shmobile_suspend_init(). This is often because shmobile_init_late lacks a __init annotation or the annotation of shmobile_suspend_init is wrong. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Cc: Rafael J.

| * ARM: shmobile: Add A4S cpuidle state on sh7372Rafael J. Wysocki2012-09-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a "C5" cpuidle state to the SH7372 SoC connected to the A4S power domain in such a way that A4S may be turned off by cpuidle if all I/O devices in that domain have been suspended (or do not have attached drivers). This requires some reorganization of the initialization of SH7372 power management which affects the the boards based on it, Mackerel and AP4EVB. Signed-off-by: Rafael J.

| * ARM: shmobile: Make sh7372 cpuidle handling more straightforwardRafael J. Wysocki2012-09-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The sh7372 cpuidle code uses the same artificially designed routine shmobile_cpuidle_enter() as the .enter() callback for all of its cpuidle states. However, shmobile_cpuidle_enter() calls a different "enter" function for each state using an array of function pointers populated by the sh7372 PM initialization code. Moreover, the states[] array of the shmobile cpuidle driver is populated by that code as well, although in principle it just might have been filled with static data. All of that complexity goes away if the sh7372 cpuidle code is allowed to define its own cpuidle driver structure that can be passed for registration to the common shmobile cpuidle initialization routine, so modify the code accordingly.

| * ARM: shmobile: Move definition of shmobile_init_late() to headerRafael J. Wysocki2012-09-03
| | | | | | | | | | | | | | | | | | | | | | | | | | The role of the only function in the common.c file in arch/arm/mach-shmobile, shmobile_init_late(), is to call two initializers whose definitions depend on kernel configuration options. Those initializers may very well be called from a static inline function in arm/mach-shmobile/include/mach/common.h, though, in which makes the code a bit easier to read. Moreover, the common.c may be dropped entirely then. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl> Acked-by: Magnus Damm <damm@opensource.se>
| * ARM: shmobile: Rework adding devices to PM domains on MackerelRafael J. Wysocki2012-09-03
| | | | | | | | | | | | | | | | | | | | | | | | On SH7372 and Mackerel devices are added to PM domains through a series of rmobile_add_device_to_domain_td() calls where the last argument is always the same. This is quite inefficient, so add a common function for adding devices to PM domains that reads the domain-device pairs information from a table and use it during SH7372 and Mackerel initialization.
