From 8f3b176e8654f19f8b545ceaad08423a1214b667 Mon Sep 17 00:00:00 2001 From: INAGAKI Hiroshi <musashino.open@gmail.com> Date: Mon, 30 Mar 2020 15:47:44 +0900 Subject: [PATCH] kernel: rtl8367b: fix external interface modes The interface mode number of RGMII_33V is 7 on RTL8367, but it's 9 on RTL8367B. the external interface modes for RTL8367 are follows: - 0, Disabled - 1, RGMII - 2, MII_MAC - 3, MII_PHY - 4, TMII_MAC - 5, TMII_PHY - 6, GMII - 7, RGMII_33V the external interface modes for RTL8367B are follows: - 0, Disabled - 1, RGMII - 2, MII_MAC - 3, MII_PHY - 4, TMII_MAC - 5, TMII_PHY - 6, GMII - 7, RMII_MAC - 8, RMII_PHY - 9, RGMII_33V But the driver in U-Boot of RT-N56U GPL tar blocks using RGMII_33V (9) mode and it seems to be unsupported on RTL8367B, so drop it from switch-case in rtl8367b_extif_set_mode. ref (RTL8367): - TL-WR2453ND v1 ref (RTL8367B): - ASUS RT-N56U - TP-Link Archer C2 v1 Signed-off-by: INAGAKI Hiroshi <musashino.open@gmail.com> --- target/linux/generic/files/drivers/net/phy/rtl8367b.c | 1 - target/linux/generic/files/include/linux/rtl8367.h | 3 +++ 2 files changed, 3 insertions(+), 1 deletion(-) diff --git a/target/linux/generic/files/drivers/net/phy/rtl8367b.c b/target/linux/generic/files/drivers/net/phy/rtl8367b.c index 1b1d5001a3..3599791a51 100644 --- a/target/linux/generic/files/drivers/net/phy/rtl8367b.c +++ b/target/linux/generic/files/drivers/net/phy/rtl8367b.c @@ -781,7 +781,6 @@ static int rtl8367b_extif_set_mode(struct rtl8366_smi *smi, int id, /* set port mode */ switch (mode) { case RTL8367_EXTIF_MODE_RGMII: - case RTL8367_EXTIF_MODE_RGMII_33V: REG_RMW(smi, RTL8367B_CHIP_DEBUG0_REG, RTL8367B_DEBUG0_SEL33(id), RTL8367B_DEBUG0_SEL33(id)); diff --git a/target/linux/generic/files/include/linux/rtl8367.h b/target/linux/generic/files/include/linux/rtl8367.h index 855de6a5cc..14150393e2 100644 --- a/target/linux/generic/files/include/linux/rtl8367.h +++ b/target/linux/generic/files/include/linux/rtl8367.h @@ -39,6 +39,9 @@ enum rtl8367_extif_mode { RTL8367_EXTIF_MODE_TMII_PHY, RTL8367_EXTIF_MODE_GMII, RTL8367_EXTIF_MODE_RGMII_33V, + RTL8367B_EXTIF_MODE_RMII_MAC = 7, + RTL8367B_EXTIF_MODE_RMII_PHY, + RTL8367B_EXTIF_MODE_RGMII_33V, }; struct rtl8367_extif_config { -- 2.30.2
