This patch adds support for TPS6594 PMIC family on wakup I2C0 bus.
Theses devices provides regulators (bucks and LDOs), but also
GPIOs, a RTC, a watchdog, an ESM (Error Signal Monitor)
which monitors the SoC error output signal, and a PFSM
(Pre-configurable Finite State Machine) which manages the
operational modes of the PMIC.

Add Mallow carrier board for wifi and nonwifi variants of Toradex Verdin
AM62 SoM. Mallow is a low-cost carrier board in the Verdin family with
a small form factor and build for volume production making it ideal for
industrial and embedded applications.

Verdin SPI_1 interface has a dedicated hardware controlled chip select
that is currently configured in the same pinctrl group as MISO/MOSI/CLK,
however it is possible that it can be used only as a standard GPIO be it
a chip select or not.
To maximize flexibility and avoid duplication in the carrier board dts
files move the SPI_1 CS in a dedicated pinctrl and also adds an
additional pinctrl to simplify using SPI_1 CS as a GPIO.

connector on SK-AM62:
- Digilent PCam 5C
- ALINX AN5641
- TEVI-OV5640-*-RPI
The Digilent and ALINX modules supply a 12Mhz XCLK to the sensor, while
the TEVI module supplies a 24Mhz XCLK, thus requiring a separate

k3-am62x-.

pinconf and pinmux accessing the same 32-Bit register and setting the

DSS irq trigger type is set to IRQ_TYPE_EDGE_RISING in the DT file, but
the TRM says it is level triggered.
For some reason triggering on rising edge results in double the amount
of expected interrupts, e.g. for normal page flipping test the number of
interrupts per second is 2 * fps. It is as if the IRQ triggers on both
edges. There are no other side effects to this issue than slightly
increased CPU & power consumption due to the extra interrupt.
Switching to IRQ_TYPE_LEVEL_HIGH is correct and fixes the issue, so
let's do that.

Merge tag '6.7-rc-smb3-client-fixes-part2' of git://git.samba.org/sfrench/cifs-2.6
Pull smb client fixes from Steve French:
- ctime caching fix (for setxattr)
- encryption fix
- DNS resolver mount fix
- debugging improvements
- multichannel fixes including cases where server stops or starts
supporting multichannel after mount
- reconnect fix
- minor cleanups
* tag '6.7-rc-smb3-client-fixes-part2' of git://git.samba.org/sfrench/cifs-2.6:
cifs: update internal module version number for cifs.ko
cifs: handle when server stops supporting multichannel
cifs: handle when server starts supporting multichannel
Missing field not being returned in ioctl CIFS_IOC_GET_MNT_INFO
smb3: allow dumping session and tcon id to improve stats analysis and debugging
smb: client: fix mount when dns_resolver key is not available
smb3: fix caching of ctime on setxattr
smb3: minor cleanup of session handling code
cifs: reconnect work should have reference on server struct
cifs: do not pass cifs_sb when trying to add channels
cifs: account for primary channel in the interface list
cifs: distribute channels across interfaces based on speed
cifs: handle cases where a channel is closed
smb3: more minor cleanups for session handling routines
smb3: minor RDMA cleanup
cifs: Fix encryption of cleared, but unset rq_iter data buffers
- Documentation update: Add a note about argument and return value
fetching is the best effort because it depends on the type.
- objpool: Fix to make internal global variables static in
test_objpool.c.
- kprobes: Unify kprobes_exceptions_nofify() prototypes. There are
the same prototypes in asm/kprobes.h for some architectures, but
some of them are missing the prototype and it causes a warning.
So move the prototype into linux/kprobes.h.
- tracing: Fix to check the tracepoint event and return event at
parsing stage. The tracepoint event doesn't support %return
but if $retval exists, it will be converted to %return silently.
This finds that case and rejects it.
- tracing: Fix the order of the descriptions about the parameters
of __kprobe_event_gen_cmd_start() to be consistent with the
argument list of the function.
