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.
