[ Upstream commit 5f4bbee069 ]
When an MFD device is added, a platform_device is allocated. If this
device is linked to a DT description, the corresponding OF node is linked
to the new platform device but the OF node's refcount isn't incremented.
As of_node_put() is called during the platform device release, it leads
to a refcount underflow.
Call of_node_get() to increment the OF node's refcount when the node is
linked to the newly created platform device.

[ Upstream commit 9ac4890ac3 ]
We observed the initial probe of the da9063 failing in
da9063_get_device_type in about 30% of boots on a Xilinx ZynqMP based
board. The problem originates in da9063_i2c_blockreg_read, which uses
a single bus transaction to turn the register page and then read a
register. On the bus, this should translate to a write to register 0,
followed by a read to the target register, separated by a repeated
start. However, we found that after the write to register 0, the
controller sometimes continues directly with the register address of
the read request, without sending the chip address or a repeated start
in between, which makes the read request invalid.
To fix this, separate turning the page and reading the register into
two separate transactions. This brings the initialization code in line
with the rest of the driver, which uses register maps (which to my
knowledge do not use repeated starts after turning the page). This has
been included in our kernel for several months and was recently
included in a shipped product. For us, it reliably fixes the issue,
and we have not observed any new issues.
While the underlying problem is probably with the i2c controller or
its driver, I still propose a change here in the interest of
robustness: First, I'm not sure this issue can be fixed on the
controller side, since there are other issues related to repeated
start which can't (AR# 60695, AR# 61664). Second, similar problems
might exist with other controllers.

[ Upstream commit 364752aa0c ]
clang-21 warns about one uninitialized variable getting dereferenced
in madera_dev_init:
drivers/mfd/madera-core.c:739:10: error: variable 'mfd_devs' is uninitialized when used here [-Werror,-Wuninitialized]
739 | mfd_devs, n_devs,

drivers/mfd/madera-core.c:459:33: note: initialize the variable 'mfd_devs' to silence this warning
459 | const struct mfd_cell *mfd_devs;
| ^
| = NULL
The code is actually correct here because n_devs is only nonzero
when mfd_devs is a valid pointer, but this is impossible for the
compiler to see reliably.
Change the logic to check for the pointer as well, to make this easier
for the compiler to follow.

[ Upstream commit 88828c7e94 ]
On newer boards featuring the A523 SoC, the AXP323 (related to the
AXP313) is paired with the AXP717 and serves as a secondary PMIC
providing additional regulator outputs. However the MFD cells are all
registered with PLATFORM_DEVID_NONE, which causes the regulator cells
to conflict with each other.
Commit e37ec32188 ("mfd: axp20x: Allow multiple regulators") attempted
to fix this by switching to PLATFORM_DEVID_AUTO so that the device names
would all be different, however that broke IIO channel mapping, which is
also tied to the device names. As a result the change was later reverted.
Instead, here we attempt to make sure the AXP313/AXP323 regulator cell
does not conflict by explicitly giving it an ID number. This was
previously done for the AXP809+AXP806 pair used with the A80 SoC.

without a consistent value to compare it to isn't useful. There isn't a

For TPS65215, there is a consistent value in bits 5-0 of the DEV_ID

There's no need to list "tc3589x" in the DT match table. The I2C core
will strip any vendor prefix and match against the i2c_device_id table
which has an "tc3589x" entry.
Probably "tc3589x" and TC3589X_UNKNOWN could be removed altogether.
Use of that compatible was only on some STE platforms and was dropped
in 2013. There were ABI breaks in 2014 claiming no DTs in the wild. See
commit 1637d480f8 ("pinctrl: nomadik: force-convert to generic config
bindings").

There are 2G and 4G RAM versions of the Lenovo Yoga Tab 3 X90F and it
turns out that the 2G version has a DMI product name of
"CHERRYVIEW D1 PLATFORM" where as the 4G version has
"CHERRYVIEW C0 PLATFORM". The sys-vendor + product-version check are
unique enough that the product-name check is not necessary.
Drop the product-name check so that the existing DMI match for the 4G
RAM version also matches the 2G RAM version.

This pull request contains some cleanups to the core and some mostly
minor updates to a bunch of drivers and device tree bindings. One thing
worth pointing out is that it contains an immutable branch containing
support for a new mfd chip (Analog Devices ADP5585) with several sub
drivers. So expect to get the four affected commits also from my fellow
MFD and GPIO maintainers.

Jones for preparing the above mentioned immutable branch.

This is a platform/x86 library that is mostly being used by other
drivers not directly under arch/x86 anyway (with the exception of the
Intel MID setup code) so it makes sense that it lives under the
platform_data/x86/ directory instead.
No functional changes intended.
