Merge tag 'efi-urgent' of git://git.kernel.org/pub/scm/linux/kernel/git/mfleming/efi into x86/urgent
Pull EFI fixes from Matt Fleming: * WARN_ON(!spin_is_locked()) always triggers on non-SMP machines. Swap it for the more canonical lockdep_assert_held() which always does the right thing - Guenter Roeck * Assign the correct value to efi.runtime_version on arm64 so that all the runtime services can be invoked - Semen Protsenko Signed-off-by: Ingo Molnar <mingo@kernel.org>

+* Clock bindings for Freescale i.MX21
+
+Required properties:
+- compatible : Should be "fsl,imx21-ccm".
+- reg : Address and length of the register set.
+- interrupts : Should contain CCM interrupt.
+- #clock-cells: Should be <1>.
+
+The clock consumer should specify the desired clock by having the clock
+ID in its "clocks" phandle cell. See include/dt-bindings/clock/imx21-clock.h
+for the full list of i.MX21 clock IDs.
+
+Examples:
+ clks: ccm@10027000{
+ compatible = "fsl,imx21-ccm";
+ reg = <0x10027000 0x800>;
+ #clock-cells = <1>;
+ };
+
+ uart1: serial@1000a000 {
+ compatible = "fsl,imx21-uart";
+ reg = <0x1000a000 0x1000>;
+ interrupts = <20>;
+ clocks = <&clks IMX21_CLK_UART1_IPG_GATE>,
+ <&clks IMX21_CLK_PER1>;
+ clock-names = "ipg", "per";
+ status = "disabled";
+ };
