* ARM: sunxi: Rework the restart codeMaxime Ripard2013-04-081-23/+35
| | | | | | | | | | | | | | | | The Allwinner sun6i (A31) has a slightly different watchdog, that doesn't allow to use the already existing restart code. Rework a bit the restart code to allow to plug in more easily different restart handlers depending on the device tree. In the past, we were also meaning sunxi as a generic name covering all Allwinner SoCs. This won't be true anymore with the A31 (sun6i) that differs pretty much from sun4i and sun5i, and we will end up having sunxi, for sun4i and sun5i, and sun6i, which is neither consistent nor convenient. So, while we're at it, also change sunxi to sun4i. Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com>
* irqchip: sunxi: Make use of the IRQCHIP_DECLARE macroMaxime Ripard2013-04-081-3/+2
| | | | | | | | This allows to remove some boilerplate code. At the same time, call the set_handle_irq function in the initialization function of the irqchip, so that we can remove it from the machine declaration. Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com>
* clocksource: sunxi: Rename sunxi to sun4iMaxime Ripard2013-04-081-2/+2
| | | | | | | | | | | | | | | | | | 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.

* clocksource: sunxi: make use of CLKSRC_OFMaxime Ripard2013-04-082-2/+10
| | | | | | | | Using CLKSRC_OF allows to remove the SoC specific sunxi_timer.h header, and instead of using a custom init function in the machine definition use the standard clocksource_of_init function. Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com>

This is dominated largely by the Samsung platforms (s3c, s5p, exynos) and a few of the others moving code out of arch/arm into more appropriate subsystems. The clocksource and irqchip drivers are now abstracted to the point where platforms that are already cleaned up do not need to even specify the driver they use, it can all get configured from the device tree as we do for normal device drivers. The clocksource changes basically touch every single platform in the process. We further clean up the use of platform specific header files here, with the goal of turning more of the platforms over to being "multiplatform" enabled, which implies that they cannot expose their headers to architecture independent code any more. It is expected that no functional changes are part of the cleanup. The overall reduction in total code lines is mostly the result of removing broken and obsolete code." * tag 'cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (133 commits) ARM: mvebu: correct gated clock documentation ARM: kirkwood: add missing include for nsa310 ARM: exynos: move exynos4210-combiner to drivers/irqchip mfd: db8500-prcmu: update resource passing drivers/db8500-cpufreq: delete dangling include ARM: at91: remove NEOCORE 926 board sunxi: Cleanup the reset code and add meaningful registers defines ARM: S3C24XX: header mach/regs-mem.h local ARM: S3C24XX: header mach/regs-power.h local ARM: S3C24XX: header mach/regs-s3c2412-mem.h local ARM: S3C24XX: Remove plat-s3c24xx directory in arch/arm/ ARM: S3C24XX: transform s3c2443 subirqs into new structure ARM: S3C24XX: modify s3c2443 irq init to initialize all irqs ARM: S3C24XX: move s3c2443 irq code to irq.c ARM: S3C24XX: transform s3c2416 irqs into new structure ARM: S3C24XX: modify s3c2416 irq init to initialize all irqs ARM: S3C24XX: move s3c2416 irq init to common irq code ARM: S3C24XX: Modify s3c_irq_wake to use the hwirq property ARM: S3C24XX: Move irq syscore-ops to irq-pm clocksource: always define CLOCKSOURCE_OF_DECLARE ...

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Allwinner SoCs have an IP module that handle both the muxing and the GPIOs. This IP has 8 banks of 32 bits, with a number of pins actually useful for each of these banks varying from one to another, and depending on the SoC used on the board. This driver only implements the pinctrl part, the gpio part will come eventually.
