From 6b9170887e1b912b657dab4597f8b44ae4dbdf50 Mon Sep 17 00:00:00 2001 From: Stefan Wahren <stefan.wahren@i2se.com> Date: Wed, 16 Nov 2016 17:52:06 +0000 Subject: [PATCH] ARM: bcm2835: Fix names for the Raspberry Pi GPIO lines There are some differences between the schematics and the official firmware DTS [1]. So based on these additional information the following has been changed: * use consistent "CAM_GPIO1" for camera LED * use consistent "CAM_GPIO0" for camera shutdown * add "USB_LIMIT" for USB current limit (0=600mA, 1=1200mA) [1] - https://github.com/raspberrypi/firmware/blob/master/extra/dt-blob.dts Signed-off-by: Stefan Wahren <stefan.wahren@i2se.com> Signed-off-by: Eric Anholt <eric@anholt.net> --- arch/arm/boot/dts/bcm2835-rpi-a-plus.dts | 4 ++-- arch/arm/boot/dts/bcm2835-rpi-a.dts | 4 ++-- arch/arm/boot/dts/bcm2835-rpi-b-plus.dts | 2 +- arch/arm/boot/dts/bcm2835-rpi-b.dts | 4 ++-- 4 files changed, 7 insertions(+), 7 deletions(-) --- a/arch/arm/boot/dts/bcm2835-rpi-a-plus.dts +++ b/arch/arm/boot/dts/bcm2835-rpi-a-plus.dts @@ -63,13 +63,13 @@ "SCL0", "NC", /* GPIO30 */ "NC", /* GPIO31 */ - "NC", /* GPIO32 */ + "CAM_GPIO1", /* GPIO32 */ "NC", /* GPIO33 */ "NC", /* GPIO34 */ "PWR_LOW_N", /* GPIO35 */ "NC", /* GPIO36 */ "NC", /* GPIO37 */ - "NC", /* GPIO38 */ + "USB_LIMIT", /* GPIO38 */ "NC", /* GPIO39 */ "PWM0_OUT", /* GPIO40 */ "CAM_GPIO0", /* GPIO41 */ --- a/arch/arm/boot/dts/bcm2835-rpi-a.dts +++ b/arch/arm/boot/dts/bcm2835-rpi-a.dts @@ -29,7 +29,7 @@ "SDA1", "SCL1", "GPIO_GCLK", - "CAM_CLK", + "CAM_GPIO1", "LAN_RUN", "SPI_CE1_N", "SPI_CE0_N", @@ -52,7 +52,7 @@ "GPIO24", "GPIO25", "NC", /* GPIO26 */ - "CAM_GPIO", + "CAM_GPIO0", /* Binary number representing build/revision */ "CONFIG0", "CONFIG1", --- a/arch/arm/boot/dts/bcm2835-rpi-b-plus.dts +++ b/arch/arm/boot/dts/bcm2835-rpi-b-plus.dts @@ -71,7 +71,7 @@ "PWR_LOW_N", /* GPIO35 */ "NC", /* GPIO36 */ "NC", /* GPIO37 */ - "NC", /* GPIO38 */ + "USB_LIMIT", /* GPIO38 */ "NC", /* GPIO39 */ "PWM0_OUT", /* GPIO40 */ "CAM_GPIO0", /* GPIO41 */ --- a/arch/arm/boot/dts/bcm2835-rpi-b.dts +++ b/arch/arm/boot/dts/bcm2835-rpi-b.dts @@ -30,7 +30,7 @@ "SDA1", "SCL1", "GPIO_GCLK", - "CAM_CLK", + "CAM_GPIO1", "LAN_RUN", "SPI_CE1_N", "SPI_CE0_N", @@ -53,7 +53,7 @@ "GPIO24", "GPIO25", "NC", /* GPIO26 */ - "CAM_GPIO", + "CAM_GPIO0", /* Binary number representing build/revision */ "CONFIG0", "CONFIG1",
