[ Upstream commit 88828c7e940dd45d139ad4a39d702b23840a37c5 ]
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 e37ec3218870 ("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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
