Subject: [PATCH 45/48] net: dsa: mt7530: simplify link operations

The "MT7621 Giga Switch Programming Guide v0.3", "MT7531 Reference Manual
|
|
|
|
|
|
for Development Board v1.0", and "MT7988A Wi-Fi 7 Generation Router
|
|
|
|
|
|
Platform: Datasheet (Open Version) v0.1" documents show that these bits are
|
|
|
|
|
|
enabled at reset:
|
|
|
|
|
|
|
|
|
|
|
|
PMCR_IFG_XMIT(1) (not part of PMCR_LINK_SETTINGS_MASK)
|
|
|
|
|
|
PMCR_MAC_MODE (not part of PMCR_LINK_SETTINGS_MASK)
|
|
|
|
|
|
PMCR_TX_EN
|
|
|
|
|
|
PMCR_RX_EN
|
|
|
|
|
|
PMCR_BACKOFF_EN (not part of PMCR_LINK_SETTINGS_MASK)
|
|
|
|
|
|
PMCR_BACKPR_EN (not part of PMCR_LINK_SETTINGS_MASK)
|
|
|
|
|
|
PMCR_TX_FC_EN
|
|
|
|
|
|
PMCR_RX_FC_EN
|
|
|
|
|
|
|
|
|
|
|
|
These bits also don't exist on the MT7530_PMCR_P(6) register of the switch
|
|
|
|
|
|
on the MT7988 SoC:
|
|
|
|
|
|
|
|
|
|
|
|
PMCR_IFG_XMIT()
|
|
|
|
|
|
PMCR_MAC_MODE
|
|
|
|
|
|
PMCR_BACKOFF_EN
|
|
|
|
|
|
PMCR_BACKPR_EN
|
|
|
|
|
|
|
|
|
|
|
|
Remove the setting of the bits not part of PMCR_LINK_SETTINGS_MASK on
|
|
|
|
|
|
phylink_mac_config as they're already set.
|
|
|
|
|
|
|
|
|
|
|
|
The bit for setting the port on force mode is already done on
|
|
|
|
|
|
mt7530_setup() and mt7531_setup_common(). So get rid of
|
|
|
|
|
|
PMCR_FORCE_MODE_ID() which helped determine which bit to use for the switch
|
|
|
|
|
|
model.
