Subject: [PATCH net-next v2 0/3] dt-bindings: dp83867: add binding for io_impedance_ctrl nvmem cell
Date: Tue, 14 Jun 2022 10:46:09 +0200 [thread overview]
Message-ID: <20220614084612.325229-1-linux@rasmusvillemoes.dk> (raw)
In-Reply-To: <20220606202220.1670714-1-linux@rasmusvillemoes.dk>
We have a board where measurements indicate that the current three
options - leaving IO_IMPEDANCE_CTRL at the reset value (which is
factory calibrated to a value corresponding to approximately 50 ohms)
or using one of the two boolean properties to set it to the min/max
value - are too coarse.
This series adds a device tree binding for an nvmem cell which can be
populated during production with a suitable value calibrated for each
board, and corresponding support in the driver. The second patch adds
a trivial phy wrapper for dev_err_probe(), used in the third.
v2: Improve commit message for patch 1; add Rob's R-b to patch 1. No
changes in the patches themselves.
Since Dan Murphy's email address bounces, cc'ing two other @ti.com
addresses that have touched the driver in recent years.
