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.

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.

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. - -Signed-off-by: Arınç ÜNAL ---- - drivers/net/dsa/mt7530.c | 59 ++++++++++++++++++++-------------------- - drivers/net/dsa/mt7530.h | 50 ++++++++++++++++------------------ - 2 files changed, 54 insertions(+), 55 deletions(-) - ---- a/drivers/net/dsa/mt7530.c -+++ b/drivers/net/dsa/mt7530.c -@@ -417,23 +417,23 @@ mt7530_setup_port6(struct dsa_switch *ds - - mt7530_rmw(priv, MT7530_P6ECR, P6_INTF_MODE_MASK, P6_INTF_MODE(1)); - -- xtal = mt7530_read(priv, MT7530_MHWTRAP) & HWTRAP_XTAL_MASK; -+ xtal = mt7530_read(priv, MT753X_MTRAP) & MT7530_XTAL_MASK; - -- if (xtal == HWTRAP_XTAL_25MHZ) -+ if (xtal == MT7530_XTAL_25MHZ) - ssc_delta = 0x57; - else - ssc_delta = 0x87; - - if (priv->id == ID_MT7621) { - /* PLL frequency: 125MHz: 1.0GBit */ -- if (xtal == HWTRAP_XTAL_40MHZ) -+ if (xtal == MT7530_XTAL_40MHZ) - ncpo1 = 0x0640; -- if (xtal == HWTRAP_XTAL_25MHZ) -+ if (xtal == MT7530_XTAL_25MHZ) - ncpo1 = 0x0a00; - } else { /* PLL frequency: 250MHz: 2.0Gbit */ -- if (xtal == HWTRAP_XTAL_40MHZ) -+ if (xtal == MT7530_XTAL_40MHZ) - ncpo1 = 0x0c80; -- if (xtal == HWTRAP_XTAL_25MHZ) -+ if (xtal == MT7530_XTAL_25MHZ) - ncpo1 = 0x1400; - } - -@@ -456,19 +456,20 @@ mt7530_setup_port6(struct dsa_switch *ds - static void - mt7531_pll_setup(struct mt7530_priv *priv) - { -+ enum mt7531_xtal_fsel xtal; - u32 top_sig; - u32 hwstrap; -- u32 xtal; - u32 val; - - val = mt7530_read(priv, MT7531_CREV); - top_sig = mt7530_read(priv, MT7531_TOP_SIG_SR); -- hwstrap = mt7530_read(priv, MT7531_HWTRAP); -+ hwstrap = mt7530_read(priv, MT753X_TRAP); - if ((val & CHIP_REV_M) > 0) -- xtal = (top_sig & PAD_MCM_SMI_EN) ?
