From 35e372a3a1f016648f278aeb7b55fe347b6699da Mon Sep 17 00:00:00 2001 From: Ray Jui Date: Mon, 21 Sep 2015 15:12:49 -0700 Subject: [PATCH] ARM: dts: enable touchscreen support on Cygnus This patch enables touchscreen support on bcm958300k and bcm958305k. Touchscreen is connected to these boards through the bcm9hmidc daughter card, and therefore also adding bcm9hmidc.dtsi that describes the daughter card Signed-off-by: Ray Jui Reviewed-by: Vikram Prakash Reviewed-by: Scott Branden Signed-off-by: Florian Fainelli --- arch/arm/boot/dts/bcm-cygnus.dtsi | 10 ++++++++ arch/arm/boot/dts/bcm958300k.dts | 1 + arch/arm/boot/dts/bcm958305k.dts | 1 + arch/arm/boot/dts/bcm9hmidc.dtsi | 42 +++++++++++++++++++++++++++++++ 4 files changed, 54 insertions(+) create mode 100644 arch/arm/boot/dts/bcm9hmidc.dtsi diff --git a/arch/arm/boot/dts/bcm-cygnus.dtsi b/arch/arm/boot/dts/bcm-cygnus.dtsi index 33ec6a51e45d..24e058c73700 100644 --- a/arch/arm/boot/dts/bcm-cygnus.dtsi +++ b/arch/arm/boot/dts/bcm-cygnus.dtsi @@ -32,6 +32,7 @@ #include #include +#include #include "skeleton.dtsi" @@ -257,5 +258,14 @@ interrupt-controller; interrupts = ; }; + + touchscreen: tsc@180a6000 { + compatible = "brcm,iproc-touchscreen"; + reg = <0x180a6000 0x40>; + clocks = <&asiu_clks BCM_CYGNUS_ASIU_ADC_CLK>; + clock-names = "tsc_clk"; + interrupts = ; + status = "disabled"; + }; }; }; diff --git a/arch/arm/boot/dts/bcm958300k.dts b/arch/arm/boot/dts/bcm958300k.dts index d8dc9f045640..2e31581dc25e 100644 --- a/arch/arm/boot/dts/bcm958300k.dts +++ b/arch/arm/boot/dts/bcm958300k.dts @@ -33,6 +33,7 @@ /dts-v1/; #include "bcm-cygnus.dtsi" +#include "bcm9hmidc.dtsi" / { model = "Cygnus SVK (BCM958300K)"; diff --git a/arch/arm/boot/dts/bcm958305k.dts b/arch/arm/boot/dts/bcm958305k.dts index 9863a19ab1bd..288a637abf3b 100644 --- a/arch/arm/boot/dts/bcm958305k.dts +++ b/arch/arm/boot/dts/bcm958305k.dts @@ -33,6 +33,7 @@ /dts-v1/; #include "bcm-cygnus.dtsi" +#include "bcm9hmidc.dtsi" / { model = "Cygnus Wireless Audio (BCM958305K)"; diff --git a/arch/arm/boot/dts/bcm9hmidc.dtsi b/arch/arm/boot/dts/bcm9hmidc.dtsi new file mode 100644 index 000000000000..65397c088335 --- /dev/null +++ b/arch/arm/boot/dts/bcm9hmidc.dtsi @@ -0,0 +1,42 @@ +/* + * BSD LICENSE + * + * Copyright(c) 2015 Broadcom Corporation.
