The rx filter, in mt7921 series, may be changed in fw operation. There is

Add dts for yt8521 and yt8531s, add driver for yt8531.
 These patches have been verified on our AM335x platform (motherboard)
 which has one integrated yt8521 and one RGMII interface.
 It can connect to daughter boards like yt8531s or yt8531 board.

 v5:
 - change the compatible of yaml
 - change the maintainers of yaml from "frank sae" to "Frank Sae"

 v4:
 - change default tx delay from 150ps to 1950ps
 - add compatible for yaml

 v3:
 - change default rx delay from 1900ps to 1950ps
 - moved ytphy_rgmii_clk_delay_config_with_lock from yt8521's patch to yt8531's patch
 - removed unnecessary checks of phydev->attached_dev->dev_addr

 v2:
 - split BIT macro as one patch
 - split "dts for yt8521/yt8531s ... " patch as two patches
 - use standard rx-internal-delay-ps and tx-internal-delay-ps, removed motorcomm,sds-tx-amplitude
 - removed ytphy_parse_dt, ytphy_probe_helper and ytphy_config_init_helper
