Merge tag 'soc-drivers-7.1' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
Pull SoC driver updates from Arnd Bergmann:
"The driver updates again are all over the place with many minor fixes
going into platform specific code. The most notable changes are:
- Support for Microchip pic64gx system controllers
- Work on cleaning up devicetree bindings for SoC drivers, and
converting them into the new format
- Lots of smaller changes for Qualcomm SoC drivers, including support
for a number of newly supported chips
- reset controller API cleanups and a new driver for Cix Sky1
- Reworks of the Tegra PMC and CBB drivers, along with a change to
how individual Tegra SoCs get selected in Kconfig and BPMP firmware
driver updates including a refresh of the ABI header to match the
version used by firmware
- STM32 updates to the firewall bus driver and support for the debug
bus through OP-TEE
- SCMI firmware driver improvements for reliability, in particular
for dealing with broken firmware interrupts
- Memory driver updates for Tegra, and a patch to remove the unused
Baikal T1 driver"
