ARM: tegra: paz00: Configure WiFi rfkill switch through device tree

2026-03-27T23:56:36+00:00

As of d64c732dfc9e ("net: rfkill: gpio: add DT support") rfkill-gpio
device can be instantiated via device tree.

Add the declaration there and drop board-paz00.c file and relevant
Makefile fragments.

ARM: tegra: paz00: Use software nodes to describe GPIOs for WiFi rfkill

2024-06-28T15:52:16+00:00

Complete conversion of the WiFi rfkill device to use device properties/
software nodes by utilizing PROPERTY_ENTRY_GPIO() instead of a lookup
table.

power: remove pda_power supply driver

2023-02-01T16:23:38+00:00

This driver was used for a couple of Intel PXA and Samsung S3C24xx
based PDAs, but all of those are now removed from the kernel, so
the driver itself is no longer useful.

ARM: 9263/1: use .arch directives instead of assembler command line flags

2022-11-08T18:36:17+00:00

Similar to commit a6c30873ee4a ("ARM: 8989/1: use .fpu assembler
directives instead of assembler arguments").

GCC and GNU binutils support setting the "sub arch" via -march=,
-Wa,-march, target function attribute, and .arch assembler directive.

Clang was missing support for -Wa,-march=, but this was implemented in
clang-13.

The behavior of both GCC and Clang is to
prefer -Wa,-march= over -march= for assembler and assembler-with-cpp
sources, but Clang will warn about the -march= being unused.

clang: warning: argument unused during compilation: '-march=armv6k'
[-Wunused-command-line-argument]

Since most assembler is non-conditionally assembled with one sub arch
(modulo arch/arm/delay-loop.S which conditionally is assembled as armv4
based on CONFIG_ARCH_RPC, and arch/arm/mach-at91/pm-suspend.S which is
conditionally assembled as armv7-a based on CONFIG_CPU_V7), prefer the
.arch assembler directive.

Add a few more instances found in compile testing as found by Arnd and
Nathan.

Pull ARM SoC driver updates from Arnd Bergmann:
 "These are updates for drivers that are tied to a particular SoC,
  including the correspondig device tree bindings:

   - A couple of reset controller changes for unisoc, uniphier, renesas
     and zte platforms

   - memory controller driver fixes for omap and tegra

   - Rockchip io domain driver updates

   - Lots of updates for qualcomm platforms, mostly touching their
     firmware and power management drivers

   - Tegra FUSE and firmware driver updateѕ

   - Support for virtio transports in the SCMI firmware framework

   - cleanup of ixp4xx drivers, towards enabling multiplatform support
     and bringing it up to date with modern platforms

   - Minor updates for keystone, mediatek, omap, renesas"

The old device property API is going to be removed.

node API equivalent, device_create_managed_software_node().

Both PMC and cpuidle drivers are probed at the same init level and
cpuidle depends on the PMC suspend mode. Add new default suspend mode
that indicates whether PMC driver has been probed and reset the mode in
a case of deferred probe of the PMC driver.

ARM: tegra: Don't enable unused PLLs on resume from suspend

2021-01-19T17:20:42+00:00

PLLC and PLLM are usually disabled on system suspend because all devices
which use these PLLs are either suspended or switched away to other clock
source. Don't enable unused PLLs on resume from suspend by keeping track
of the enable-state of the PLLs across suspend-resume.
