[ Upstream commit 6d1d41c075a1a54ba03370e268171fec20e06563 ] Issue: When PEC is enabled, binding adm1272 to the adm1275 would fail due to PEC error. See below: adm1275: probe of xxxx failed with error -74 Diagnosis: Per the datasheet of adm1272, adm1278, adm1293 and amd1294, PMON_CONFIG (0xd4) is 16bits wide. On the other hand, PMON_CONFIG (0xd4) for adm1275 is 8bits wide. The driver should not assume everything is 8bits wide and read only 8bits from it. Solution: If it is adm1272, adm1278, adm1293 and adm1294, use i2c_read_word. Else, use i2c_read_byte Testing: Binding adm1272 to the driver. The change is only tested on adm1272.

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.
