2024-08-29ARM: tegra: Wire up two front panel LEDs on TrimSliceTomasz Maciej Nowak1-5/+25
Pins responsible for controlling these LEDs need to have tristate control removed if we want them as GPIOs. This change aligns with pinmux configuration of "dte" pin group in downstream kernel[1]. These LEDs had no function assigned on vendor kernel and there is no label on the case, the only markings are on PCB which are part of node names (ds1 marking is on power LED controlled by PMIC), so generic term is assigned as the function. 1. https://github.com/compulab/trimslice-android-kernel/blob/upstream/arch/arm/mach-tegra/board-trimslice-pinmux.c#L45 Signed-off-by: Tomasz Maciej Nowak <[email protected]> Signed-off-by: Thierry Reding <[email protected]>

2024-02-16ARM: tegra: Enable cros-ec-spi as wake sourceMark Hasemeyer2-0/+2
The cros_ec driver currently assumes that cros-ec-spi compatible device nodes are a wakeup-source even though the wakeup-source property is not defined. Some Chromebooks use a separate wake pin, while others overload the interrupt for wake and IO. With the current assumption, spurious wakes can occur on systems that use a separate wake pin. It is planned to update the driver to no longer assume that the EC interrupt pin should be enabled for wake. Add the wakeup-source property to all cros-ec-spi compatible device nodes to signify to the driver that they should still be a valid wakeup source.

2023-12-18ASoC: tegra: tegra20_ac97: Convert to use GPIO descriptorsLinus Walleij1-1/+1
The Tegra20 AC97 driver is using the legacy GPIO APIs in <linux/of_gpio.h> and <linux/gpio.h> to obtain GPIOs for reset and sync. Convert it over and fix the polarity error on the RESET line in the process: this reset line is clearly active low. Just fix the one in-tree device tree site using it at the same time.

2023-07-27ARM: tegra: Provide specific compatible string for Nexus 7 panelThierry Reding1-8/+4
panel-lvds alone is not a valid compatible string and we always need a specific compatible string as well. Nexus 7 can come with one of (at least) two panels, so pick one of them as the specific compatible string. Signed-off-by: Thierry Reding <[email protected]>
2023-07-27ARM: tegra: Use Hannstar HSD101PWW2 on Pegatron ChagallThierry Reding1-1/+1
The LVDS bindings require a specific compatible string in addition to the generic "panel-lvds". Add the HannStar HSD101PWW2 which is used on a similar device (ASUS TF201) and seems to work fine with slightly modified timings in DT.

2023-07-27ARM: tegra: Reuse I2C3 for NVECThierry Reding1-10/+9
Instead of duplicating the I2C3 node and adding NVEC specific properties, reuse the I2C3 node, extend it with NVEC specific properties and drop properties that are not needed by NVEC. This results in a DTB that is a bit cleaner and avoids accidentally using I2C3 and NVEC which would have them fight over the same hardware resources. Signed-off-by: Thierry Reding <[email protected]>
2023-07-21ARM: tegra: Add missing reset-names for Tegra HS UARTThierry Reding14-0/+30
The device tree bindings for the Tegra high-speed UART require the reset-names property, so add it whenever the compatible string for the serial port is overwritten. Signed-off-by: Thierry Reding <[email protected]>
2023-07-21ARM: tegra: Remove reset-names for UART devicesThierry Reding4-18/+0
The UART devices found on Tegra chips have a single reset connected to them, so a reset-names property isn't needed. In fact, the device tree bindings don't allow this property, so remove them to allow the nodes to be properly validated. Signed-off-by: Thierry Reding <[email protected]>
2023-07-21ARM: tegra: Remove dmas and dma-names for debug UARTThierry Reding24-0/+50
The debug UART doesn't support DMA and the DT bindings prohibit the use of the dmas and dma-names properties for it, so remove them. Signed-off-by: Thierry Reding <[email protected]>
2023-06-21ARM: dts: Move .dts files to vendor sub-directoriesRob Herring72-0/+69620
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.
