acf6f33163 dt-bindings: arm: stm32: add extra SiP compatible for lxa,stm32mp157c-mc1
The Linux Automation MC-1 is built around an OSD32MP15x SiP with CPU,
RAM, PMIC, Oscillator and EEPROM. Adjust the binding, so the SiP
compatible is contained as well. This allows boot firmware to match
against it to apply fixups if necessary.

a24bde12f9 dt-bindings: vendor-prefixes: document Octavo Systems oct prefix
Octavo Systems is an American company specializing in design and
manufacturing of System-in-Package devices.

The prefix is already in use for the Octavo Systems OSD3358-SM-RED
device tree, but was so far undocumented. Fix this.

b19d3a55d4 ARM: dts: stm32: support child mfd cells for the stm32mp1 TAMP syscon
The stm32mp1 TAMP peripheral has 32 backup registers that survive
a warm reset. This makes them suitable for storing a reboot
mode, which the vendor's kernel tree is already doing[0].

The actual syscon-reboot-mode child node can be added by a board.dts or
fixed up by the bootloader. For the child node to be probed, the
compatible needs to include simple-mfd. The binding now specifies this,
so have the SoC dtsi adhere to it.

82765d1495 dt-bindings: arm: stm32: add simple-mfd compatible for tamp node
The stm32mp1 TAMP (Tamper and backup registers) does tamper detection
and features 32 backup registers that, being in the RTC domain, may
survive even with Vdd switched off.

This makes it suitable for use to communicate a reboot mode from OS
to bootloader via the syscon-reboot-mode binding. Add a "simple-mfd"
to support probing such a child node. The actual reboot mode
node could then be defined in a board.dts or fixed up by the bootloader.

83686162c0 ARM: dts: stm32: add STUSB1600 Type-C using I2C4 on stm32mp15xx-dkx
This patch adds support for STUSB1600 USB Type-C port controller, used on
I2C4 on stm32mp15xx-dkx.
The default configuration on this board, on Type-C connector, is:
- Dual Power Role (DRP), so set power-role to "dual";
- Vbus limited to 500mA, so set typec-power-opmode to "default" (it means
  500mA in USB 2.0).
typec-power-opmode is used to reconfigure the STUSB1600 advertising of
current capability when its NVM is not in line with the board layout.
On stm32mp15xx-dkx, Vbus power source of STUSB1600 is 5V_VIN. So power
operation mode depends on the power supply used. To avoid any power
issues, it is better to limit Vbus to 500mA on this board.
ALERT# is the interrupt pin of STUSB1600. It needs an external pull-up, and
signal is active low.

USB OTG controller ID and Vbus signals are not connected on stm32mp15xx-dkx
boards, so disconnection are not detected.
Without DWC2 usb-role-switch:
- if you unplug the USB cable from the Type-C port, you have to manually
disconnect the USB gadget:
echo disconnect > /sys/devices/platform/soc/49000000.usb-otg/udc/49000000.usb-otg/soft_connect
- Then you can plug the USB cable again in the Type-C port, and manually
reconnect the USB gadget:
echo connect > /sys/devices/platform/soc/49000000.usb-otg/udc/49000000.usb-otg/soft_connect
With DWC2 usb-role-switch, USB gadget is dynamically disconnected or connected.

23224e4500 mm: remove kzfree() compatibility definition
Commit 453431a549 ("mm, treewide: rename kzfree() to
kfree_sensitive()") renamed kzfree() to kfree_sensitive(),
but it left a compatibility definition of kzfree() to avoid
being too disruptive.

Since then a few more instances of kzfree() have slipped in.

Just get rid of them and remove the compatibility definition
once and for all.

0f7f635b06 checkpatch: enable GIT_DIR environment use to set git repository location
If set, use the environment variable GIT_DIR to change the default .git
location of the kernel git tree.

If GIT_DIR is unset, keep using the current ".git" default.

Pull more parisc updates from Helge Deller:

 - During this merge window O_NONBLOCK was changed to become 000200000,
   but we missed that the syscalls timerfd_create(), signalfd4(),
   eventfd2(), pipe2(), inotify_init1() and userfaultfd() do a strict
   bit-wise check of the flags parameter.

   To provide backward compatibility with existing userspace we
   introduce parisc specific wrappers for those syscalls which filter
   out the old O_NONBLOCK value and replaces it with the new one.

 - Prevent HIL bus driver to get stuck when keyboard or mouse isn't
   attached

 - Improve error return codes when setting rtc time
