This patch series should fix and extend the patch V4 "ARM: bcm2835: Add names for the Raspberry Pi GPIO lines" from Linus Walleij and Eric Anholt. Changes in V2: - fix URL to firmware DT blob - drop dtsi file since Model A+ and Zero aren't identical Stefan Wahren (2): ARM: bcm2835: Fix names for the Raspberry Pi GPIO lines ARM: bcm2835: Add names for the RPi Zero GPIO lines 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 +- arch/arm/boot/dts/bcm2835-rpi-zero.dts | 65 ++++++++++++++++++++++++++++++ 5 files changed, 72 insertions(+), 7 deletions(-) -- 1.7.9.5

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> --- 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(-) diff --git a/arch/arm/boot/dts/bcm2835-rpi-a-plus.dts b/arch/arm/boot/dts/bcm2835-rpi-a-plus.dts index 5a22c79..d070454 100644 --- 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 */ diff --git a/arch/arm/boot/dts/bcm2835-rpi-a.dts b/arch/arm/boot/dts/bcm2835-rpi-a.dts index 54f98c5..46d078e 100644 --- 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", diff --git a/arch/arm/boot/dts/bcm2835-rpi-b-plus.dts b/arch/arm/boot/dts/bcm2835-rpi-b-plus.dts index b67587e..432088e 100644 --- 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 */ diff --git a/arch/arm/boot/dts/bcm2835-rpi-b.dts b/arch/arm/boot/dts/bcm2835-rpi-b.dts index 71f50e1..4d56fe3 100644 --- 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", -- 1.7.9.5
