Date: Mon,  6 Jun 2022 22:22:17 +0200	[thread overview]
Message-ID: <20220606202220.1670714-1-linux@rasmusvillemoes.dk> (raw)

We have a board where measurements indicate that the current three
options - leaving IO_IMPEDANCE_CTRL at the (factory calibrated) reset
value 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.

Rasmus Villemoes (3):
  dt-bindings: dp83867: add binding for io_impedance_ctrl nvmem cell
  linux/phy.h: add phydev_err_probe() wrapper for dev_err_probe()
  net: phy: dp83867: implement support for io_impedance_ctrl nvmem cell
