James Byrne 83f71ef558 net: phy: micrel: Use correct skew values on KSZ9021 ... Commit ff7bd212cb ("net: phy: micrel: fix divisor value for KSZ9031 phy skew") fixed the skew value divisor for the KSZ9031, but left the code using the same divisor for the KSZ9021, which is incorrect. The preceding commit c16e69f702 ("net: phy: micrel: add documentation for Micrel KSZ90x1 binding") added the DTS documentation for the KSZ90x1, changing it from the equivalent file in the Linux kernel to correctly state that for this part the skew value is set in 120ps steps, whereas the Linux documentation and driver continue to this day to use the incorrect value of 200 that came from the original KSZ9021 datasheet before it was corrected in revision 1.2 (Feb 2014). This commit sorts out the resulting confusion in a consistent way by making the following changes: - Update the documentation to be clear about what the skew values mean, in the same was as for the KSZ9031. - Update the Micrel PHY driver to select the appropriate divisor for both parts. - Adjust all the device trees that state skew values for KSZ9021 PHYs to use values based on 120ps steps instead of 200ps steps. This will result in the same values being programmed into the skew registers as the equivalent device trees in the Linux kernel do, where it incorrectly uses 200ps steps (since that's where all these device trees were copied from).
