+Subject: [PATCH 01/15] net: dsa: mt7530: disable EEE abilities on failure on
+ MT7531 and MT7988
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The MT7531_FORCE_EEE1G and MT7531_FORCE_EEE100 bits let the
+PMCR_FORCE_EEE1G and PMCR_FORCE_EEE100 bits determine the 1G/100 EEE
+abilities of the MAC. If MT7531_FORCE_EEE1G and MT7531_FORCE_EEE100 are
+unset, the abilities are left to be determined by PHY auto polling.
+
+The commit 40b5d2f15c09 ("net: dsa: mt7530: Add support for EEE features")
+made it so that the PMCR_FORCE_EEE1G and PMCR_FORCE_EEE100 bits are set on
+mt753x_phylink_mac_link_up(). But it did not set the MT7531_FORCE_EEE1G and
+MT7531_FORCE_EEE100 bits. Because of this, the EEE abilities will be
+determined by PHY auto polling, regardless of the result of phy_init_eee().
+
+Define these bits and add them to the MT7531_FORCE_MODE mask which is set
+in mt7531_setup_common(). With this, there won't be any EEE abilities set
+when phy_init_eee() returns a negative value.
+
+Thanks to Russell for explaining when phy_init_eee() could return a
+negative value below.
+
+Looking at phy_init_eee(), it could return a negative value when:
+
+1. phydev->drv is NULL
+2. if genphy_c45_eee_is_active() returns negative
+3. if genphy_c45_eee_is_active() returns zero, it returns -EPROTONOSUPPORT
+4. if phy_set_bits_mmd() fails (e.g. communication error with the PHY)
+
+If we then look at genphy_c45_eee_is_active(), then:
+
+genphy_c45_read_eee_adv() and genphy_c45_read_eee_lpa() propagate their
+non-zero return values, otherwise this function returns zero or positive
+integer.
+
+If we then look at genphy_c45_read_eee_adv(), then a failure of
+phy_read_mmd() would cause a negative value to be returned.
+
+Looking at genphy_c45_read_eee_lpa(), the same is true.
+
+So, it can be summarised as:
+
+- phydev->drv is NULL
+- there is a communication error accessing the PHY
+- EEE is not active
+
+otherwise, it returns zero on success.
+
+If one wishes to determine whether an error occurred vs EEE not being
+supported through negotiation for the negotiated speed, if it returns
+-EPROTONOSUPPORT in the latter case. Other error codes mean either the
+driver has been unloaded or communication error.
+
+In conclusion, determining the EEE abilities by PHY auto polling shouldn't
+result in having any EEE abilities enabled, when one of the last two
+situations in the summary happens. And it seems that if phydev->drv is
+NULL, there would be bigger problems with the device than a broken link. So
+this is not a bugfix.

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The MT7530_PMCR_P() registers are on MT7530, MT7531, and the switch on the
+MT7988 SoC. Rename the definition for them to MT753X_PMCR_P(). Bit 15 is
+for MT7530 only. Add MT7530 prefix to the definition for bit 15.
+
+Use GENMASK and FIELD_PREP for PMCR_IFG_XMIT().
+
+Rename PMCR_TX_EN and PMCR_RX_EN to PMCR_MAC_TX_EN and PMCR_MAC_TX_EN to
+follow the naming on 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.
+
+These documents show that PMCR_RX_FC_EN is at bit 5. Correct this along
+with renaming it to PMCR_FORCE_RX_FC_EN, and the same for PMCR_TX_FC_EN.
+
+Remove PMCR_SPEED_MASK which doesn't have a use.
+
+Rename the force mode definitions for MT7531 to FORCE_MODE. Add MASK at the
+end for the mask that includes all force mode definitions.

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The p5_intf_sel pointer is used to store the information of whether PHY
+muxing is used or not. PHY muxing is a feature specific to port 5 of the
+MT7530 switch. Do not use it for other switch models.
+
+Rename the pointer to p5_mode to store the mode the port is being used in.
+Rename the p5_interface_select enum to mt7530_p5_mode, the string
+representation to mt7530_p5_mode_str, and the enum elements.
+
+If PHY muxing is not detected, the default mode, GMAC5, will be used.

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The mt753x_bpdu_port_fw enum is globally used for manipulating the process
+of deciding the forwardable ports, specifically concerning the CPU port(s).
+Therefore, rename it and the values in it to mt753x_to_cpu_fw.
+
+Change FOLLOW_MFC to SYSTEM_DEFAULT to be on par with the switch documents.

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The MT7530_MFC register is on MT7530, MT7531, and the switch on the MT7988
+SoC. Rename it to MT753X_MFC. Bit 7 to 0 differs between MT7530 and
+MT7531/MT7988. Add MT7530 prefix to these definitions, and define the
+IGMP/MLD Query Frame Flooding Ports mask for MT7531.
+
+Rename the cases of MIRROR_MASK to MIRROR_PORT_MASK.
+
+Move mt753x_mirror_port_get() and mt753x_port_mirror_set() to mt7530.h as
+macros.

+Subject: [PATCH 06/15] net: dsa: mt7530: refactor MT7530_HWTRAP and
+ MT7530_MHWTRAP
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The MT7530_HWTRAP and MT7530_MHWTRAP registers are on MT7530 and MT7531.
+It's called hardware trap on MT7530, software trap on MT7531. That's
+because some bits of the trap on MT7530 cannot be modified by software
+whilst all bits of the trap on MT7531 can. Rename the definitions for them
+to MT753X_TRAP and MT753X_MTRAP. Add MT7530 and MT7531 prefixes to the
+definitions specific to the switch model.
+
+Remove the extra parentheses from MT7530_XTAL_40MHZ and MT7530_XTAL_20MHZ.
+
+Rename MHWTRAP_PHY0_SEL, MHWTRAP_MANUAL, and MHWTRAP_PHY_ACCESS to be on
+par with the "MT7621 Giga Switch Programming Guide v0.3" document.
+
+Make an enumaration for the XTAL frequency. Set the data type of the xtal
+variable on mt7531_pll_setup() to it.

+Subject: [PATCH 07/15] net: dsa: mt7530: move MT753X_MTRAP operations for
+ MT7530
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+On MT7530, the media-independent interfaces of port 5 and 6 are controlled
+by the MT7530_P5_DIS and MT7530_P6_DIS bits of the hardware trap. Deal with
+these bits only when the relevant port is being enabled or disabled. This
+ensures that these ports will be disabled when they are not in use.
+
+Do not set MT7530_CHG_TRAP on mt7530_setup_port5() as that's already being
+done on mt7530_setup().
+
+Instead of globally setting MT7530_P5_MAC_SEL, clear it, then set it only
+on the appropriate case.
+
+If PHY muxing is detected, clear MT7530_P5_DIS before calling
+mt7530_setup_port5().

+
+Remove the comment on mt753x_phylink_get_caps() as it's become invalid with

+Add break to case 6 of mt7988_mac_port_get_caps() to be explicit.

+MIME-Version: 1.0

+Content-Transfer-Encoding: 8bit
+
+Unlike MT7531BE, the GPIO 6-12 pins are not used for RGMII on MT7531AE.
+Therefore, the GPIO 11-12 pins are set to function as MDC and MDIO to
+expose the MDIO bus of the switch. Replace the comment with a better
+explanation.

+Subject: [PATCH 01/15] net: dsa: mt7530: disable EEE abilities on failure on
+ MT7531 and MT7988
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The MT7531_FORCE_EEE1G and MT7531_FORCE_EEE100 bits let the
+PMCR_FORCE_EEE1G and PMCR_FORCE_EEE100 bits determine the 1G/100 EEE
+abilities of the MAC. If MT7531_FORCE_EEE1G and MT7531_FORCE_EEE100 are
+unset, the abilities are left to be determined by PHY auto polling.
+
+The commit 40b5d2f15c09 ("net: dsa: mt7530: Add support for EEE features")
+made it so that the PMCR_FORCE_EEE1G and PMCR_FORCE_EEE100 bits are set on
+mt753x_phylink_mac_link_up(). But it did not set the MT7531_FORCE_EEE1G and
+MT7531_FORCE_EEE100 bits. Because of this, the EEE abilities will be
+determined by PHY auto polling, regardless of the result of phy_init_eee().
+
+Define these bits and add them to the MT7531_FORCE_MODE mask which is set
+in mt7531_setup_common(). With this, there won't be any EEE abilities set
+when phy_init_eee() returns a negative value.
+
+Thanks to Russell for explaining when phy_init_eee() could return a
+negative value below.
+
+Looking at phy_init_eee(), it could return a negative value when:
+
+1. phydev->drv is NULL
+2. if genphy_c45_eee_is_active() returns negative
+3. if genphy_c45_eee_is_active() returns zero, it returns -EPROTONOSUPPORT
+4. if phy_set_bits_mmd() fails (e.g. communication error with the PHY)
+
+If we then look at genphy_c45_eee_is_active(), then:
+
+genphy_c45_read_eee_adv() and genphy_c45_read_eee_lpa() propagate their
+non-zero return values, otherwise this function returns zero or positive
+integer.
+
+If we then look at genphy_c45_read_eee_adv(), then a failure of
+phy_read_mmd() would cause a negative value to be returned.
+
+Looking at genphy_c45_read_eee_lpa(), the same is true.
+
+So, it can be summarised as:
+
+- phydev->drv is NULL
+- there is a communication error accessing the PHY
+- EEE is not active
+
+otherwise, it returns zero on success.
+
+If one wishes to determine whether an error occurred vs EEE not being
+supported through negotiation for the negotiated speed, if it returns
+-EPROTONOSUPPORT in the latter case. Other error codes mean either the
+driver has been unloaded or communication error.
+
+In conclusion, determining the EEE abilities by PHY auto polling shouldn't
+result in having any EEE abilities enabled, when one of the last two
+situations in the summary happens. And it seems that if phydev->drv is
+NULL, there would be bigger problems with the device than a broken link. So
+this is not a bugfix.

+Subject: [PATCH 02/15] net: dsa: mt7530: refactor MT7530_PMCR_P()
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The MT7530_PMCR_P() registers are on MT7530, MT7531, and the switch on the
+MT7988 SoC. Rename the definition for them to MT753X_PMCR_P(). Bit 15 is
+for MT7530 only. Add MT7530 prefix to the definition for bit 15.
+
+Use GENMASK and FIELD_PREP for PMCR_IFG_XMIT().
+
+Rename PMCR_TX_EN and PMCR_RX_EN to PMCR_MAC_TX_EN and PMCR_MAC_TX_EN to
+follow the naming on 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.
+
+These documents show that PMCR_RX_FC_EN is at bit 5. Correct this along
+with renaming it to PMCR_FORCE_RX_FC_EN, and the same for PMCR_TX_FC_EN.
+
+Remove PMCR_SPEED_MASK which doesn't have a use.
+
+Rename the force mode definitions for MT7531 to FORCE_MODE. Add MASK at the
+end for the mask that includes all force mode definitions.

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8

+
+The p5_intf_sel pointer is used to store the information of whether PHY
+muxing is used or not. PHY muxing is a feature specific to port 5 of the
+MT7530 switch. Do not use it for other switch models.
+
+Rename the pointer to p5_mode to store the mode the port is being used in.
+Rename the p5_interface_select enum to mt7530_p5_mode, the string
+representation to mt7530_p5_mode_str, and the enum elements.
+
+If PHY muxing is not detected, the default mode, GMAC5, will be used.

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The mt753x_bpdu_port_fw enum is globally used for manipulating the process
+of deciding the forwardable ports, specifically concerning the CPU port(s).
+Therefore, rename it and the values in it to mt753x_to_cpu_fw.
+
+Change FOLLOW_MFC to SYSTEM_DEFAULT to be on par with the switch documents.

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The MT7530_MFC register is on MT7530, MT7531, and the switch on the MT7988
+SoC. Rename it to MT753X_MFC. Bit 7 to 0 differs between MT7530 and
+MT7531/MT7988. Add MT7530 prefix to these definitions, and define the
+IGMP/MLD Query Frame Flooding Ports mask for MT7531.
+
+Rename the cases of MIRROR_MASK to MIRROR_PORT_MASK.
+
+Move mt753x_mirror_port_get() and mt753x_port_mirror_set() to mt7530.h as
+macros.

+Subject: [PATCH 06/15] net: dsa: mt7530: refactor MT7530_HWTRAP and
+ MT7530_MHWTRAP
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The MT7530_HWTRAP and MT7530_MHWTRAP registers are on MT7530 and MT7531.
+It's called hardware trap on MT7530, software trap on MT7531. That's
+because some bits of the trap on MT7530 cannot be modified by software
+whilst all bits of the trap on MT7531 can. Rename the definitions for them
+to MT753X_TRAP and MT753X_MTRAP. Add MT7530 and MT7531 prefixes to the
+definitions specific to the switch model.
+
+Remove the extra parentheses from MT7530_XTAL_40MHZ and MT7530_XTAL_20MHZ.
+
+Rename MHWTRAP_PHY0_SEL, MHWTRAP_MANUAL, and MHWTRAP_PHY_ACCESS to be on
+par with the "MT7621 Giga Switch Programming Guide v0.3" document.
+
+Make an enumaration for the XTAL frequency. Set the data type of the xtal
+variable on mt7531_pll_setup() to it.

+Subject: [PATCH 07/15] net: dsa: mt7530: move MT753X_MTRAP operations for
+ MT7530
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+On MT7530, the media-independent interfaces of port 5 and 6 are controlled
+by the MT7530_P5_DIS and MT7530_P6_DIS bits of the hardware trap. Deal with
+these bits only when the relevant port is being enabled or disabled. This
+ensures that these ports will be disabled when they are not in use.
+
+Do not set MT7530_CHG_TRAP on mt7530_setup_port5() as that's already being
+done on mt7530_setup().
+
+Instead of globally setting MT7530_P5_MAC_SEL, clear it, then set it only
+on the appropriate case.
+
+If PHY muxing is detected, clear MT7530_P5_DIS before calling
+mt7530_setup_port5().

+Subject: [PATCH 15/15] net: dsa: mt7530: explain exposing MDIO bus of MT7531AE
+ better
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Unlike MT7531BE, the GPIO 6-12 pins are not used for RGMII on MT7531AE.
+Therefore, the GPIO 11-12 pins are set to function as MDC and MDIO to
+expose the MDIO bus of the switch. Replace the comment with a better
+explanation.
