So we need adjust some phy parameters to improve the compatibility issue. It is a little different between simulation and real chip. We have no idea about which configuration is better before tape-out. We set default settings according to simulation, but need to tune these parameters after getting the real chip. I can't explain every change in detail here. The below information is just a rough description: PHY_REG_REV: Disable internal clkreq_tx, enable rx_pwst PHY_BPCR: No change, just turn the magic number to macro definitions PHY_PCR: Change OOBS sensitivity, from 60mV to 90mV PHY_RCR2: Control charge-pump current automatically PHY_FLD4: Use TX cmu reference clock PHY_RDR: Change RXDSEL from 30nF to 1.9nF PHY_RCR1: Change the duration between adp_st and asserting cp_en from 0.32 us to 0.64us PHY_FLD3: Adjust internal timers PHY_TUNE: Fine tune the regulator12 output voltage Signed-off-by: Wei WANG Signed-off-by: Lee Jones --- Reading git-diff-tree failed
