2024-09-05ARM: dts: Fix undocumented LM75 compatible nodesRob Herring1-2/+2
"lm75" without any vendor is undocumented. It works with the Linux kernel since the I2C subsystem will do matches of the compatible string without a vendor prefix to the i2c_device_id and/or driver name. Mostly replace "lm75" with "national,lm75" as that's the original part vendor and the compatible which matches what "lm75" matched with. In a couple of cases the node name or compatible gives a clue to the actual part and vendor and a more specific compatible can be used. In these cases, it does change the variant the kernel picks. "nct75" is an OnSemi part which is compatible with TI TMP75C based on a comparison of the OnSemi NCT75 datasheet and configuration the Linux driver uses. Adding an OnSemi compatible would be an ABI change. "nxp,lm75" is most likely an NXP part. Alexander Stein says the i.MX53 boards are a NXP LM75A as well. NXP makes a LM75A and LM75B. Both are 11-bit resolution and 100ms sample time. The "national,lm75a" is 9-bit, so "national,lm75b" is the closest match for both NXP variants. While we're here, fix the node names to use the generic name "temperature-sensor".

2024-07-08ARM: dts: ixp4xx: nslu2: beeper uses PWMLinus Walleij1-2/+9
The beeper in the NSLU2 is just a GPIO connected to a speaker, so we need to use PWM on the GPIO to get any kind of sound out. Tested with some random beeps by enabling INPUT_EVDEV and running beep.c with e.g. beep 400 for a 400 Hz tone.

2024-02-20arm: dts: Fix dtc interrupt_map warningsRob Herring2-0/+4
The dtc interrupt_map warning is off because its dependency, interrupt_provider, is off by default. Fix all the warnings so it can be enabled.

2023-07-17arm64: dts: socfpga: change the reset-name of "stmmaceth-ocp" to "ahb"Dinh Nguyen1-3/+3
The "stmmaceth-ocp" reset line on the SoCFPGA stmmac ethernet driver is the same as the "ahb" reset on a standard stmmac ethernet. commit ("843f603762a5 dt-bindings: net: snps,dwmac: Add 'ahb' reset/reset-name") documented the second reset signal as 'ahb' instead of 'stmmaceth-ocp'. Change the reset-names of the SoCFPGA DWMAC driver to 'ahb'. In order not to break ABI, we will keep support in thedwmac-socfpga driver to still make use of "stmmaceth-ocp". This also fixes the dtbs_check warning: ethernet@ff802000: reset-names:1: 'ahb' was expected Signed-off-by: Dinh Nguyen <[email protected]> --- v2: update commit message to further describe the reason for the change
2023-06-21ARM: dts: Move .dts files to vendor sub-directoriesRob Herring64-0/+8975
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.
