2023-06-21ARM: dts: Move .dts files to vendor sub-directoriesRob Herring1-118/+0
The arm dts directory has grown to 1559 boards which makes it a bit unwieldy to maintain and use. Past attempts stalled out due to plans to move .dts files out of the kernel tree. Doing that is no longer planned (any time soon at least), so let's go ahead and group .dts files by vendors. This move aligns arm with arm64 .dts file structure. There's no change to dtbs_install as the flat structure is maintained on install. The naming of vendor directories is roughly in this order of preference: - Matching original and current SoC vendor prefix/name (e.g. ti, qcom) - Current vendor prefix/name if still actively sold (SoCs which have been aquired) (e.g. nxp/imx) - Existing platform name for older platforms not sold/maintained by any company (e.g. gemini, nspire) The whole move was scripted with the exception of MAINTAINERS and a few makefile fixups.

2022-11-10ARM: dts: bcm283x: Move ACT LED into separate dtsiStefan Wahren1-6/+5
The usage of the label property for gpio-leds has been deprecated a long time ago. In bcm2835-rpi.dtsi the ACT LED uses such a label and derive it to almost every Raspberry Pi board. Since we cannot break userspace interface this property must be kept. But we can move the ACT LED into a separate dtsi and include them from the board files. This change have two benefits: - with both new refs it's now clear the LED part is included from a dtsi - new boards do not include the deprecated stuff automatically Reported-by: Alexander Dahl <ada@thorsis.com> Signed-off-by: Stefan Wahren <stefan.wahren@i2se.com> Link: https://lore.kernel.org/r/20221110173105.6633-3-stefan.wahren@i2se.com Signed-off-by: Florian Fainelli <f.fainelli@gmail.com>
2022-11-10ARM: dts: bcm283x: Remove bcm2835-rpi-common.dtsi from SoC DTSIMaxime Ripard1-0/+1
According to the commit log of the commit 3ac395a5b3f3 ("ARM: dts: bcm283x: Use firmware PM driver for V3D"), the initial intent behind the bcm2835-rpi-common DTSI was to share data between the RaspberryPies based on the BCM2835, 36 and 37. However, it was included by these SoCs' main DTSI. This is creating an improper layering. On top of that, bcm2835.dtsi is being included by bcm2711.dtsi, which means that, even though the bcm2835-rpi-common DTSI wasn't actually meant to contain data for the BCM2711, it actually leaks into the BCM2711 DTSI. In order to remove both issues, let's remove the include of bcm2835-rpi-common.dtsi from bcm283{5-7}.dtsi and put them into the bcm283{6,7}-rpi.dtsi. BCM2835 has to be handled with special care due to the fact that bcm2835.dtsi is being included by bcm2711.dtsi. Thus, we chose to include bcm2835-rpi-common.dtsi directly into the board DTS. This will be more error-prone, but given that it's a fairly old SoC by now, the chance that we will get more BCM2835 boards is fairly low. BCM2711 isn't modified since the content of bcm2835-rpi-common.dtsi was only a power-domain for the v3d that was overridden anyway.

2019-08-12ARM: dts: bcm283x: Define MMC interfaces at board levelStefan Wahren1-0/+7
Starting with RPi 4 this is the first board, which doesn't use sdhost as default SD interface. So the MMC interfaces should be defined finally at board level. Since all boards using sdhci already does this, we can drop the pinctrl part from bcm2835-rpi.dtsi. Signed-off-by: Stefan Wahren <wahrenst@gmx.net> Acked-by: Eric Anholt <eric@anholt.net>

Until RPI 3 and Zero W the pl011 (uart0) was always on pin 14/15. So in order to take care of them and other boards in the future, we need to define UART pinmuxing on board level. This work based on Eric Anholt's patch "ARM: bcm2385: Don't force pl011 onto pins 14/15." and Fabian Vogt's patch "ARM64: dts: bcm2837: assign uart0 to BT and uart1 to pin headers".
