* ARM: integrator: define clocks in the device treesLinus Walleij2014-02-131-2/+100
| | | | | | | This adds the clock definitions to the Integrator/CP and Integrator/AP device trees. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
* ARM: integrator: pass parent IRQ to the SICLinus Walleij2014-01-031-0/+3
| | | | | | The SIC is cascaded off the PIC, so specify this in the device tree. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

Among the things new for this release are: - More support for the AM33xx platforms from TI - Tegra 124 support, and some updates to older tegra families as well - imx cleanups and updates across the board - A rename of Broadcom's Mobile platforms which were introduced as ARCH_BCM, and turned out to be too broad a name. New name is ARCH_BCM_MOBILE. - A whole bunch of updates and fixes for integrator, making the platform code more modern and switches over to DT-only booting. - Support for two new Renesas shmobile chipsets. Next up for them is more work on consolidation instead of introduction of new non-multiplatform SoCs, we're all looking forward to that! - Misc cleanups for older Samsung platforms, some Allwinner updates, etc" * tag 'soc-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (159 commits) ARM: bcm281xx: Add ARCH_BCM_MOBILE to bcm config ARM: bcm_defconfig: Run "make savedefconfig" ARM: bcm281xx: Add ARCH Timers to config rename ARCH_BCM to ARCH_BCM_MOBILE (mach-bcm) ARM: vexpress: Enable platform-specific options in defconfig ARM: vexpress: Make defconfig work again ARM: sunxi: remove .init_time hooks ARM: imx: enable suspend for imx6sl ARM: imx: ensure dsm_request signal is not asserted when setting LPM ARM: imx6q: call WB and RBC configuration from imx6q_pm_enter() ARM: imx6q: move low-power code out of clock driver ARM: imx: drop extern with function prototypes in common.h ARM: imx: reset core along with enable/disable operation ARM: imx: do not return from imx_cpu_die() call ARM: imx_v6_v7_defconfig: Select CONFIG_PROVE_LOCKING ARM: imx_v6_v7_defconfig: Enable LEDS_GPIO related options ARM: mxs_defconfig: Turn off CONFIG_DEBUG_GPIO ARM: imx: replace imx6q_restart() with mxc_restart() ARM: mach-imx: mm-imx5: Retrieve iomuxc base address from dt ARM: mach-imx: mm-imx5: Retrieve tzic base address from dt ...
| * ARM: integrator: core module registers from compatible stringsLinus Walleij2013-10-161-2/+2
| | | | | | | | | | | | | | | | | | | | This augments the core machine code for the Integrator platforms to get their references to the core module device nodes by using compatible strings instead of predefined node names and rename the CP syscon node to be simply "syscon".

* | ARM: integrator: deactivate timer0 on the Integrator/CPLinus Walleij2013-10-131-5/+4
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes a long-standing Integrator/CP regression from commit 870e2928cf3368ca9b06bc925d0027b0a56bcd8e "ARM: integrator-cp: convert use CLKSRC_OF for timer init" When this code was introduced, the both aliases pointing the system to use timer1 as primary (clocksource) and timer2 as secondary (clockevent) was ignored, and the system would simply use the first two timers found as clocksource and clockevent. However this made the system timeline accelerate by a factor x25, as it turns out that the way the clocking actually works (totally undocumented and found after some trial-and-error) is that timer0 runs @ 25MHz and timer1 and timer2 runs @ 1MHz. Presumably this divider setting is a boot-on default and configurable albeit the way to configure it is not documented. So as a quick fix to the problem, let's mark timer0 as disabled, so the code will chose timer1 and timer2 as it used to. This also deletes the two aliases for the primary and secondary timer as they have been superceded by the auto-selection Cc: stable@vger.kernel.org Cc: Rob Herring <rob.herring@calxeda.com> Cc: Russell King <linux@arm.linux.org.uk> Signed-off-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Olof Johansson <olof@lixom.net>
* ARM: integrator-cp: convert use CLKSRC_OF for timer initRob Herring2013-04-111-3/+3
| | | | | | | | | | | | Move the integrator-cp timer init to timer-sp.c and use CLKSRC_OF. There is no reason to use the aliases, so drop them from the init code. The integrator-cp timers are mistakenly called sp804 timers in the dts, but in fact they are not sp804 dual timers, but single timers with the same programming model. Fix the dts to reflect this.

* ARM: integrator: hook the CP into the SoC busLinus Walleij2012-11-161-0/+5
| | | | | | | | | | | This hooks the Integrator/CP into the SoC bus when booting from device tree, by mapping the CP controller registers first, then registering the SoC device, and then populating the device tree with the SoC device as parent.

* ARM: 7519/1: integrator: convert platform devices to Device TreeLinus Walleij2012-09-171-0/+7
| | | | | | | | | This moves the physmap flash and SMSC91x ethernet devices over to the device tree, moving the static board code down into the #ifndef CONFIG_OF section. Signed-off-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* ARM: 7518/1: integrator: convert AMBA devices to device treeLinus Walleij2012-09-171-0/+49
| | | | | | | | | | | | | | | This converts the AMBA (PrimeCell) devices on the Integrator/AP and Integrator/CP over to probing from the Device Tree if the kernel is compiled for Device Tree support. We continue to #ifdef out all non-DT code and vice versa on respective boot type to get a clean cut. We need to add a bunch of auxdata (compare to the Versatile) to handle bus names and callbacks alike.
