Bug Description
The following patches should be considered for inclusion into the v5.15 linux-image-generic kernel for the Jammy release:
commit f6f7fbb89bf8dc9
Author: Vincent Pelletier <email address hidden>
Date: Tue Nov 16 23:57:42 2021 +0000
riscv: dts: sifive unmatched: Link the tmp451 with its power supply
Fixes the following probe warning:
lm90 0-004c: Looking up vcc-supply from device tree
lm90 0-004c: Looking up vcc-supply property in node /soc/i2c@
lm90 0-004c: supply vcc not found, using dummy regulator

riscv: dts: sifive unmatched: Fix regulator for board rev3
The existing values are rejected by the da9063 regulator driver, as they
are unachievable with the declared chip setup (non-merged vcore and bmem
are unable to provide the declared curent).
Fix voltages to match rev3 schematics, which also matches their boot-up
configuration within the chip's available precision.
Declare bcore1/bcore2 and bmem/bio as merged.
Set ldo09 and ldo10 as always-on as their consumers are not declared but
exist.
Drop ldo current limits as there is no current limit feature for these
regulators in the DA9063. Fixes warnings like:
DA9063_LDO3: Operation of current configuration missing

riscv: dts: sifive unmatched: Expose the PMIC sub-functions
These sub-functions are available in the chip revision on this board, so
expose them.

commit 8120393b74b31bb
Author: Vincent Pelletier <email address hidden>
Date: Tue Nov 16 23:57:38 2021 +0000
riscv: dts: sifive unmatched: Expose the board ID eeprom
Mark it as read-only as it is factory-programmed with identifying
information, and no executable nor configuration:
- eth MAC address
- board model (PCB version, BoM version)
- board serial number
Accidental modification would cause misidentification which could brick
the board, so marking read-only seem like both a safe and non-constraining
choice.

riscv: dts: unmatched: Add gpio card detect to mmc-spi-slot
Per HiFive Unmatched schematics, the card detect signal of the
micro SD card is connected to gpio pin #15, which should be
reflected in the DT via the <gpios> property, as described in
