2014-10-31ARM: nomadik: device tree for NHK15 boardLinus Walleij1-0/+1
This adds a device tree for the Nomadik NHK15 development kit board. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2014-05-30ARM: l2c: nomadik: convert to generic l2c OF initialisationRussell King1-10/+3
Remove the explicit call to l2x0_of_init(), converting to the generic infrastructure instead. This also allows us to eliminate the .init_machine function as it is identical to the generic version.

2014-05-30ARM: l2c: nomadik: remove cache size overrideRussell King1-1/+1
The cache size should already be present in the L2 cache auxiliary control register: it is part of the integration process to configure the hardware IP. Most platforms get this right, yet still many cargo-cult program, and assume that they always need specifying to the L2 cache code. Remove them so we can find out which really need this.

2013-11-28ARM: nomadik: get rid of explicit ethernet GPIO managementLinus Walleij1-32/+0
We used to set up the GPIO used for the SMC ethernet IRQ by requesting the GPIO line explicitly. As we recently established that specifying the GPIO controller as interrupt parent and requesting one of its interrupts by reference should be enough, we do away with this. Incidentally, the Nomadik GPIO chip driver handles this just fine: the IRQ is set up and fired as expected. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2013-10-07Merge branch 'clk-of-init-v2_for-3.13' of ↵Olof Johansson1-36/+0
https://github.com/shesselba/linux-dove into next/cleanup From Sebastian Hasselbarth: This is a patch set based on an RFC [1][2] sent earlier to provide a common arch/arm init for DT clock providers. Currently, the call to of_clk_init(NULL) to initialize DT clock providers is spread among several mach-dirs. Since most machs require DT clocks initialized before timers, no initcall can be used. By adding of_clk_init(NULL) to arch/arm time_init(), we can remove all mach-specific .init_time hooks that basically called of_clk_init and clocksource_of_init. In contrast to the RFC version, of_clk_init(NULL) is now only called if no custom .init_time callback is set. This allows some machs to still call clock init themselves, as not all can be converted now. Therefore, this patch sets drops conversion of mach-mvebu and mach-zynq. New machs that were introduced with v3.12-rc1 are also converted, except mach-u300 that requires clocks before irqs. * 'clk-of-init-v2_for-3.13' of https://github.com/shesselba/linux-dove: (29 commits) ARM: vt8500: remove custom .init_time hook ARM: vexpress: remove custom .init_time hook ARM: tegra: remove custom .init_time hook ARM: sunxi: remove custom .init_time hook ARM: sti: remove custom .init_time hook ARM: socfpga: remove custom .init_time hook ARM: rockchip: remove custom .init_time hook ARM: prima2: remove custom .init_time hook ARM: nspire: remove custom .init_time hook ARM: nomadik: remove custom .init_time hook ARM: mxs: remove custom .init_time hook ARM: kirkwood: remove custom .init_time hook ARM: imx: remove custom .init_time hook ARM: highbank: remove custom .init_time hook ARM: exynos: remove custom .init_time hook ARM: dove: remove custom .init_time hook ARM: bcm2835: remove custom .init_time hook ARM: bcm: provide common arch init for DT clocks ARM: call of_clk_init from default time_init handler ARM: vt8500: prepare for arch-wide .init_time callback ...

2013-09-29clk: nomadik: declare OF clock providerSebastian Hesselbarth1-3/+2
Common clock framework allows to register clock providers to get called on of_clk_init() by using CLK_OF_DECLARE. This converts nomadik clock provider to make use of it and get rid of the mach specific clk init call. As clocks require system reset controller base address to be initialized each clock driver checks src_base and calls new nomadik_src_init if required.

Nomadik clock initialization is properly done in clk-nomadik since patch "clk: nomadik: set all timers to use 2.4 MHz TIMCLK". Therefore, this patch removes now redundant mtu initialization from .init_time callback.

2010-05-27ARM: 6145/1: ux500 MTU clockrate correctionLinus Walleij1-0/+8
This adjusts the clockrate for the MTU timer. On the different UX500 variants this rate is different. The platform can also have been set up at hardware initialization, bootloader or early init for different clock speeds. To have the clock framework available early so the timers can use them, the clock initialization for Nomadik and ux500 is moved to IRQ init time. A custom per-clock callback is added to handle special cases like this. This solves a user-visible bug: without this patch the current UX500 platforms will not be synchronized to wall-clock time and the platform will drift in time.

2010-03-19ARM: 5972/1: nomadik-gpio: convert to platform driverRabin Vincent1-36/+47
On the U8500 platform there are four GPIO blocks, each with a 4K address space, including the peripheral identification. However, each of these blocks have a varying number of banks, each of which have 32 GPIOs and an interrupt line. The current nomadik-gpio driver implementation can handle each of these sub-banks easily with one instance each, but cannot as-is be hooked up to them because it is an AMBA driver and it expects to see a peripheral with the appropriate peripheral ids but having only one bank and only one interrupt. Solve this by converting the driver to a platform driver.
