From mboxrd@z Thu Jan 1 00:00:00 1970 From: aford173@gmail.com (Adam Ford) Date: Mon, 7 May 2018 07:37:21 -0500 Subject: [PATCH V3] ARM: dts: da850-evm: use phandles to extend nodes Message-ID: <20180507123721.9264-1-aford173@gmail.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Many node labels in the device tree (like serial0, serial1, etc) are being redefined, so let's modernize the device tree by using phandles to extend the existing nodes. This helps reduce the whitespace. Signed-off-by: Adam Ford --- V3: Rebase against 4.18/dt and fix subject. V2: Rename subject per feedback from Sekhar. Extend notes from tps6507x Add empty line after each node diff --git a/arch/arm/boot/dts/da850-evm.dts b/arch/arm/boot/dts/da850-evm.dts index 339cae353302..3c486d8675b8 100644 --- a/arch/arm/boot/dts/da850-evm.dts +++ b/arch/arm/boot/dts/da850-evm.dts @@ -27,143 +27,6 @@ spi0 = &spi1;
