These device trees add support for the TS-4600 by Technologic Systems. More details here: http://wiki.embeddedarm.com/wiki/TS-4600 Signed-off-by: Sebastien Bourdelin <sebastien.bourdelin@xxxxxxxxxxxxxxxxxxxx> --- Changes v6 -> v7: - rebase on master - remove unneeded pinctrl-name (suggested by Shawn Guo) - add reg to the node en-sd-pwr (suggested by Shawn Guo) - use define for gpio polarity (suggested by Shawn Guo) - remove the fake bus container for regulator (suggested by Shawn Guo) Changes v5 -> v6: - rebase on master - split the previous patch series into series by subsystem Changes v4 -> v5: - fix missing signed off Changes v3 -> v4: - rebase on master Changes v2 -> v3: - rebase on master Changes v1 -> v2: - rebase on master --- arch/arm/boot/dts/Makefile | 2 + arch/arm/boot/dts/imx28-ts4600-common.dtsi | 74 ++++++++++++++++++++++++++++++ arch/arm/boot/dts/imx28-ts4600-rev-a.dts | 22 +++++++++ arch/arm/boot/dts/imx28-ts4600-rev-b.dts | 22 +++++++++ 4 files changed, 120 insertions(+) create mode 100644 arch/arm/boot/dts/imx28-ts4600-common.dtsi create mode 100644 arch/arm/boot/dts/imx28-ts4600-rev-a.dts create mode 100644 arch/arm/boot/dts/imx28-ts4600-rev-b.dts diff --git a/arch/arm/boot/dts/Makefile b/arch/arm/boot/dts/Makefile index faf46abaa4a2..430fe7f1e644 100644 --- a/arch/arm/boot/dts/Makefile +++ b/arch/arm/boot/dts/Makefile @@ -532,6 +532,8 @@ dtb-$(CONFIG_ARCH_MXS) += \ imx28-m28cu3.dtb \ imx28-m28evk.dtb \ imx28-sps1.dtb \ + imx28-ts4600-rev-a.dtb \ + imx28-ts4600-rev-b.dtb \ imx28-tx28.dtb dtb-$(CONFIG_ARCH_NOMADIK) += \ ste-nomadik-s8815.dtb \ diff --git a/arch/arm/boot/dts/imx28-ts4600-common.dtsi b/arch/arm/boot/dts/imx28-ts4600-common.dtsi new file mode 100644 index 000000000000..c5f6bef87fd5 --- /dev/null +++ b/arch/arm/boot/dts/imx28-ts4600-common.dtsi @@ -0,0 +1,74 @@ +/* + * Copyright (C) 2016 Savoir-Faire Linux + * Author: Sebastien Bourdelin <sebastien.bourdelin@xxxxxxxxxxxxxxxxxxxx> + * + * The code contained herein is licensed under the GNU General Public + * License.
