2019-10-18ARM: dts: bcm2837-rpi-cm3: Avoid leds-gpio probing issueStefan Wahren
bcm2835-rpi.dtsi defines the behavior of the ACT LED, which is available on all Raspberry Pi boards. But there is no driver for this particual GPIO on CM3 in mainline yet, so this node was left incomplete without the actual GPIO definition. Since commit 025bf37725f1 ("gpio: Fix return value mismatch of function gpiod_get_from_of_node()") this causing probe issues of the leds-gpio driver for users of the CM3 dtsi file. leds-gpio: probe of leds failed with error -2 Until we have the necessary GPIO driver hide the ACT node for CM3 to avoid this.

2019-08-12ARM: dts: bcm283x: Define memory at board levelStefan Wahren
Now with the varity of several RPi boards, the memory should be defined at board level. This step gives us the chance to fix the memory size of the RPi 1 B+, Zero (incl. W) and Compute Module 1. Signed-off-by: Stefan Wahren <wahrenst@gmx.net> Acked-by: Eric Anholt <eric@anholt.net>
2019-02-01ARM: dts: bcm283x: Fix DTC warning for memory nodeStefan Wahren
Compiling the bcm283x DTS with W=1 leads to the following warning: Warning (unit_address_vs_reg): /memory: node has a reg or ranges property, but no unit name Fix this by adding the unit address.

2018-11-06ARM: dts: bcm283x: Correct vchiq compatible stringPhil Elwell
To allow VCHIQ to determine the correct cache line size, use the new "brcm,bcm2836-vchiq" compatible string on BCM2836 and BCM2837. Signed-off-by: Phil Elwell <phil@raspberrypi.org> Acked-by: Stefan Wahren <stefan.wahren@i2se.com> Signed-off-by: Stefan Wahren <stefan.wahren@i2se.com>
2018-08-27ARM: dts: add Raspberry Pi Compute Module 3 and IO boardStefan Wahren
The Raspberry Pi Compute Module 3 (CM3) and the Raspberry Pi Compute Module 3 Lite (CM3L) are SoMs which contains a BCM2837 processor, 1 GB RAM and a GPIO expander. The CM3 has a 4 GB eMMC, but on the CM3L the eMMC is unpopulated and it's up to the user to connect their own SD/MMC device. The dtsi file is designed to work for both modules. There is also a matching carrier board which is called Compute Module IO Board V3. Signed-off-by: Stefan Wahren <stefan.wahren@i2se.com>
