From: Murali Karicheri Date: Sat, 23 Nov 2013 21:26:06 +0000 (-0500) Subject: ARM: keystone: dts: add a k2hk-evm specific dts file X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=b8273f2eb5d266755a2ae2db39b2cc16f29b0941;p=linux.git ARM: keystone: dts: add a k2hk-evm specific dts file This patch adds K2 Kepler/Hawking evm (k2hk-evm) specific dts file. To enable re-use of bindings across multiple evms of this family, rename current keystone.dts to keystone.dtsi and include it in the evm specific dts file. K2 SoC has separate ref clock inputs for various clocks. So add separate ref clock nodes for ARM, DDR3A, DDR3B and PA PLL input clocks in k2hk-evm.dts. While at it, rename refclkmain to refclksys based on device User Guide naming convention Signed-off-by: Murali Karicheri Signed-off-by: Santosh Shilimkar --- diff --git a/arch/arm/boot/dts/k2hk-evm.dts b/arch/arm/boot/dts/k2hk-evm.dts new file mode 100644 index 0000000000000..15b3a95f5e3ad --- /dev/null +++ b/arch/arm/boot/dts/k2hk-evm.dts @@ -0,0 +1,55 @@ +/* + * Copyright 2013 Texas Instruments, Inc. + * + * Keystone 2 Kepler/Hawking EVM device tree + * + * This program is free software;
