07bec0e09c watchdog: at91sam9_wdt: use devm_request_irq to avoid missing free_irq() in error path
free_irq() is missing in case of error in at91_wdt_init(), use
devm_request_irq to fix that.

f769f97917 watchdog: rzg2l_wdt: Handle TYPE-B reset for RZ/V2M
As per section 48.4 of the HW User Manual, IPs in the RZ/V2M
SoC need either a TYPE-A reset sequence or a TYPE-B reset
sequence. More specifically, the watchdog IP needs a TYPE-B
reset sequence.

If the proper reset sequence isn't implemented, then resetting
IPs may lead to undesired behaviour. In the restart callback of
the watchdog driver the reset has basically no effect on the
desired funcionality, as the register writes following the reset
happen before the IP manages to come out of reset.

Implement the TYPE-B reset sequence in the watchdog driver to
address the issues with the restart callback on RZ/V2M.

6ba6f0f591 watchdog: rzg2l_wdt: Issue a reset before we put the PM clocks
On RZ/Five SoC it was observed that setting timeout (to say 1 sec) wouldn't
reset the system.

The procedure described in the HW manual (Procedure for Activating Modules)
for activating the target module states we need to start supply of the
clock module before applying the reset signal. This patch makes sure we
follow the same procedure to clear the registers of the WDT module, fixing
the issues seen on RZ/Five SoC.

While at it re-used rzg2l_wdt_stop() in rzg2l_wdt_set_timeout() as it has
the same function calls.

7bfd2747d3 watchdog: dw_wdt: stop on reboot
HW running watchdogs are just watchdogs that are enabled before the
Linux driver is probed, usually by the bootloader (eg. U-Boot).

When the system is shutting down, the mechanism for keeping a HW running
watchdog pinged is also stopped, but the watchdog itself is not stopped,
causing a reset, and preventing the system from being shut down.

Opt into stopping watchdogs on reboot.

f8ee39b44b watchdog: da9062: da9063: use unlocked xfer function in restart
Machine resets via da9062/da9063 PMICs are challenging since one needs
to use special i2c atomic transfers due to the fact interrupts are
disabled in such late system stages. This is the reason both PMICs don't
use regmap and have instead opted for i2c_smbus_write_byte_data() in
restart handlers.

However extensive testing revealed that even using atomic safe function
is not enough and occasional resets fail with error message "Failed to
shutdown (err =  -11)". This is due to the fact that function
i2c_smbus_write_byte_data() in turn calls __i2c_lock_bus_helper()
which might fail with -EAGAIN when bus lock is already taken and cannot
be released anymore.

Thus replace i2c_smbus_write_byte_data() with unlocked flavor of
i2c_smbus_xfer() function to avoid above dead-lock scenario. At this
system stage we don't care about proper locking anymore and only want
proper machine reset to be carried out.

583472ef2d OpenRISC MAINTAINERS update for 6.2
The old mailing list for OpenRISC died due to some infrastructure issues
 and the people in charge decided not to keep it running.  We have
 migrated this and the users over to kernel.org infrastructure.
 
 Sending this out now to avoid kernel developers getting lots of bounced

2b09d5d364 fbcon: Check font dimension limits
blit_x and blit_y are u32, so fbcon currently cannot support fonts
larger than 32x32.

The 32x32 case also needs shifting an unsigned int, to properly set bit
31, otherwise we get "UBSAN: shift-out-of-bounds in fbcon_set_font",
as reported on:
