Merge tag 'integrator-for-v3.15-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-integrator into next/drivers
Merge "Integrator/Versatile base patch stack for the v3.15 series" from Linus Walleij: "this is a set of patches I have sent for review and failed to get ACKs from the proper subsystem maintainers after repeated pings. However I now need to have this rotated in linux-next as a base for multiplatform, so please pull it in, it is all ARM drivers anyway. Russell pointed out some things and these have been fixed and iterated in this series." - Move integrator clock definitions to the device tree, alter clock and timer drivers accordingly. - Alter the VIC irqchip driver to support cascaded VICs off a parent IRQ controller. - Update the IM-PD1 plugin code to use managed resources. - Register the VIC on the IM-PD1. - Select the PL061 GPIO block for the IM-PD1 on the Integrator/AP. * tag 'integrator-for-v3.15-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-integrator: ARM: integrator: select GPIO block ARM: integrator: register the IM-PD1 VIC ARM: integrator: use managed resources for the IM-PD1 irqchip: support cascaded VICs irqchip: vic: update the base IRQ member correctly clk: versatile: respect parent rate in ICST clock clk: versatile: pass a parent to the ICST clock ARM: integrator: switch to fetch clocks from device tree ARM: SP804: make Integrator/CP timer pick clock from DT ARM: integrator: define clocks in the device trees Signed-off-by: Olof Johansson <olof@lixom.net>

+Clock bindings for ARM Integrator Core Module clocks
+
+Auxilary Oscillator Clock
+
+This is a configurable clock fed from a 24 MHz chrystal,
+used for generating e.g. video clocks. It is located on the
+core module and there is only one of these.
+
+This clock node *must* be a subnode of the core module, since
+it obtains the base address for it's address range from its
+parent node.
+
+
+Required properties:
+- compatible: must be "arm,integrator-cm-auxosc"
+- #clock-cells: must be <0>
+
+Optional properties:
+- clocks: parent clock(s)
+
+Example:
+
+core-module@10000000 {
+ xtal24mhz: xtal24mhz@24M {
+ #clock-cells = <0>;
+ compatible = "fixed-clock";
+ clock-frequency = <24000000>;
+ };
+ auxosc: cm_aux_osc@25M {
+ #clock-cells = <0>;
+ compatible = "arm,integrator-cm-auxosc";
+ clocks = <&xtal24mhz>;
+ };
+};
