2024-12-05ARM: tegra: nyan: Maintain power to USB ports on bootMichal Pecio
USB ports are turned on by the firmware as it looks for disks to boot, ensure that they aren't power cycled before the xHCI driver comes up. This enables USB devices to be ready for use faster and reduces wear and risk of data loss on storage devices. A particularly annoying case was booting from a mechanical disk, which takes time to spin up again. Vendor kernel also kept these ports powered, and by the same means.

2024-08-29ARM: tegra: Wire up two front panel LEDs on TrimSliceTomasz Maciej Nowak
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 <tmn505@gmail.com> Signed-off-by: Thierry Reding <treding@nvidia.com>

2024-02-16ARM: tegra: Enable cros-ec-spi as wake sourceMark Hasemeyer
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 Walleij

2023-07-27ARM: tegra: Reuse I2C3 for NVECThierry Reding
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.

2023-07-21ARM: tegra: Remove reset-names for UART devicesThierry Reding

2023-06-21ARM: dts: Move .dts files to vendor sub-directoriesRob Herring
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.
