Merge branch 'disintegrate-asm-generic' of git://git.infradead.org/users/dhowells/linux-headers into asm-generic
Patches from David Howells <dhowells@redhat.com>: This is to complete part of the UAPI disintegration for which the preparatory patches were pulled recently. Note that there are some fixup patches which are at the base of the branch aimed at you, plus all arches get the asm-generic branch merged in too. * 'disintegrate-asm-generic' of git://git.infradead.org/users/dhowells/linux-headers: UAPI: (Scripted) Disintegrate include/asm-generic UAPI: Fix conditional header installation handling (notably kvm_para.h on m68k) c6x: remove c6x signal.h UAPI: Split compound conditionals containing __KERNEL__ in Arm64 UAPI: Fix the guards on various asm/unistd.h files Signed-off-by: Arnd Bergmann <arnd@arndb.de>

+Device Tree Clock bindings for arch-vt8500
+
+This binding uses the common clock binding[1].
+
+[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
+
+Required properties:
+- compatible : shall be one of the following:
+ "via,vt8500-pll-clock" - for a VT8500/WM8505 PLL clock
+ "wm,wm8650-pll-clock" - for a WM8650 PLL clock
+ "via,vt8500-device-clock" - for a VT/WM device clock
+
+Required properties for PLL clocks:
+- reg : shall be the control register offset from PMC base for the pll clock.
+- clocks : shall be the input parent clock phandle for the clock. This should
+ be the reference clock.
+- #clock-cells : from common clock binding; shall be set to 0.
+
+Required properties for device clocks:
+- clocks : shall be the input parent clock phandle for the clock. This should
+ be a pll output.
+- #clock-cells : from common clock binding; shall be set to 0.
+
+
+Device Clocks
+
+Device clocks are required to have one or both of the following sets of
+properties:
+
+
+Gated device clocks:
+
+Required properties:
+- enable-reg : shall be the register offset from PMC base for the enable
+ register.
+- enable-bit : shall be the bit within enable-reg to enable/disable the clock.
+
+
+Divisor device clocks:
+
+Required property:
+- divisor-reg : shall be the register offset from PMC base for the divisor
+ register.
+Optional property:
+- divisor-mask : shall be the mask for the divisor register. Defaults to 0x1f
+ if not specified.
+
+
+For example:
+
+ref25: ref25M {
+ #clock-cells = <0>;
+ compatible = "fixed-clock";
+ clock-frequency = <25000000>;
+};
+
