Now this patch only shows that we move LED code from mtk-ge-soc.c to mtk-phy-lib.c & mtk-phy.h. And sure, we need to slighly modify mtk-ge-soc.c so it can use those helper functions. --- MAINTAINERS | 2 + drivers/net/phy/mediatek/Kconfig | 5 + drivers/net/phy/mediatek/Makefile | 1 + drivers/net/phy/mediatek/mtk-ge-soc.c | 251 +++---------------------- drivers/net/phy/mediatek/mtk-phy-lib.c | 235 +++++++++++++++++++++++ drivers/net/phy/mediatek/mtk.h | 80 ++++++++ 6 files changed, 347 insertions(+), 227 deletions(-) create mode 100644 drivers/net/phy/mediatek/mtk-phy-lib.c create mode 100644 drivers/net/phy/mediatek/mtk.h diff --git a/MAINTAINERS b/MAINTAINERS index 6deaf94..e58e05c 100644 --- a/MAINTAINERS +++ b/MAINTAINERS @@ -13794,7 +13794,9 @@ M: SkyLake Huang L: netdev@vger.kernel.org S: Maintained F: drivers/net/phy/mediatek/mtk-ge-soc.c +F: drivers/net/phy/mediatek/mtk-phy-lib.c F: drivers/net/phy/mediatek/mtk-ge.c +F: drivers/net/phy/mediatek/mtk.h F: drivers/phy/mediatek/phy-mtk-xfi-tphy.c MEDIATEK I2C CONTROLLER DRIVER diff --git a/drivers/net/phy/mediatek/Kconfig b/drivers/net/phy/mediatek/Kconfig index 6839ea6..448bc20 100644 --- a/drivers/net/phy/mediatek/Kconfig +++ b/drivers/net/phy/mediatek/Kconfig @@ -1,6 +1,10 @@ # SPDX-License-Identifier: GPL-2.0-only +config MTK_NET_PHYLIB + tristate + config MEDIATEK_GE_PHY tristate "MediaTek Gigabit Ethernet PHYs" + select MTK_NET_PHYLIB help Supports the MediaTek non-built-in Gigabit Ethernet PHYs. @@ -13,6 +17,7 @@ config MEDIATEK_GE_SOC_PHY tristate "MediaTek SoC Ethernet PHYs" depends on (ARM64 && ARCH_MEDIATEK) || COMPILE_TEST select NVMEM_MTK_EFUSE + select MTK_NET_PHYLIB help Supports MediaTek SoC built-in Gigabit Ethernet PHYs. diff --git a/drivers/net/phy/mediatek/Makefile b/drivers/net/phy/mediatek/Makefile index 005bde2..814879d 100644 --- a/drivers/net/phy/mediatek/Makefile +++ b/drivers/net/phy/mediatek/Makefile @@ -1,3 +1,4 @@ # SPDX-License-Identifier: GPL-2.0 +obj-$(CONFIG_MTK_NET_PHYLIB) += mtk-phy-lib.o obj-$(CONFIG_MEDIATEK_GE_PHY) += mtk-ge.o obj-$(CONFIG_MEDIATEK_GE_SOC_PHY) += mtk-ge-soc.o diff --git a/drivers/net/phy/mediatek/mtk-ge-soc.c b/drivers/net/phy/mediatek/mtk-ge-soc.c index 0eb5395..c950717 100644 --- a/drivers/net/phy/mediatek/mtk-ge-soc.c +++ b/drivers/net/phy/mediatek/mtk-ge-soc.c @@ -8,6 +8,8 @@ #include #include +#include "mtk.h" + #define MTK_GPHY_ID_MT7981 0x03a29461 #define MTK_GPHY_ID_MT7988 0x03a29481 @@ -210,41 +212,6 @@ #define MTK_PHY_DA_TX_R50_PAIR_D 0x540 /* Registers on MDIO_MMD_VEND2 */ -#define MTK_PHY_LED0_ON_CTRL 0x24 -#define MTK_PHY_LED1_ON_CTRL 0x26 -#define MTK_PHY_LED_ON_MASK GENMASK(6, 0) -#define MTK_PHY_LED_ON_LINK1000 BIT(0) -#define MTK_PHY_LED_ON_LINK100 BIT(1) -#define MTK_PHY_LED_ON_LINK10 BIT(2) -#define MTK_PHY_LED_ON_LINK (MTK_PHY_LED_ON_LINK10 |\ - MTK_PHY_LED_ON_LINK100 |\ - MTK_PHY_LED_ON_LINK1000) -#define MTK_PHY_LED_ON_LINKDOWN BIT(3) -#define MTK_PHY_LED_ON_FDX BIT(4) /* Full duplex */ -#define MTK_PHY_LED_ON_HDX BIT(5) /* Half duplex */ -#define MTK_PHY_LED_ON_FORCE_ON BIT(6) -#define MTK_PHY_LED_ON_POLARITY BIT(14) -#define MTK_PHY_LED_ON_ENABLE BIT(15) - -#define MTK_PHY_LED0_BLINK_CTRL 0x25 -#define MTK_PHY_LED1_BLINK_CTRL 0x27 -#define MTK_PHY_LED_BLINK_1000TX BIT(0) -#define MTK_PHY_LED_BLINK_1000RX BIT(1) -#define MTK_PHY_LED_BLINK_100TX BIT(2) -#define MTK_PHY_LED_BLINK_100RX BIT(3) -#define MTK_PHY_LED_BLINK_10TX BIT(4) -#define MTK_PHY_LED_BLINK_10RX BIT(5) -#define MTK_PHY_LED_BLINK_RX (MTK_PHY_LED_BLINK_10RX |\ - MTK_PHY_LED_BLINK_100RX |\ - MTK_PHY_LED_BLINK_1000RX) -#define MTK_PHY_LED_BLINK_TX (MTK_PHY_LED_BLINK_10TX |\ - MTK_PHY_LED_BLINK_100TX |\ - MTK_PHY_LED_BLINK_1000TX) -#define MTK_PHY_LED_BLINK_COLLISION BIT(6) -#define MTK_PHY_LED_BLINK_RX_CRC_ERR BIT(7) -#define MTK_PHY_LED_BLINK_RX_IDLE_ERR BIT(8) -#define MTK_PHY_LED_BLINK_FORCE_BLINK BIT(9) - #define MTK_PHY_LED1_DEFAULT_POLARITIES BIT(1) #define MTK_PHY_RG_BG_RASEL 0x115 @@ -299,10 +266,6 @@ enum CAL_MODE { SW_M }; -#define MTK_PHY_LED_STATE_FORCE_ON 0 -#define MTK_PHY_LED_STATE_FORCE_BLINK 1 -#define MTK_PHY_LED_STATE_NETDEV 2 - struct mtk_socphy_priv { unsigned long led_state; }; @@ -1131,55 +1094,11 @@ static int mt798x_phy_config_init(struct phy_device *phydev) return mt798x_phy_calibration(phydev); } -static int mt798x_phy_hw_led_on_set(struct phy_device *phydev, u8 index, - bool on) -{ - unsigned int bit_on = MTK_PHY_LED_STATE_FORCE_ON + (index ? 16 : 0); - struct mtk_socphy_priv *priv = phydev->priv; - bool changed; - - if (on) - changed = !test_and_set_bit(bit_on, &priv->led_state); - else - changed = !!test_and_clear_bit(bit_on, &priv->led_state); - - changed |= !!test_and_clear_bit(MTK_PHY_LED_STATE_NETDEV + - (index ? 16 : 0), &priv->led_state); - if (changed) - return phy_modify_mmd(phydev, MDIO_MMD_VEND2, index ? - MTK_PHY_LED1_ON_CTRL : MTK_PHY_LED0_ON_CTRL, - MTK_PHY_LED_ON_MASK, - on ?

TR is a way to access proprietary register on page 52b5. Use these helper functions so we can see which fields we're going to modify/set/clear. This patch doesn't really change registers' settings but just enhances readability and maintainability.

This will invalidate MediaTek series gigabit Ethernet PHYs' hardware auto downshift mechanism. Without this patch, if someone is trying to use "4-wire" cable to connect above devices, MediaTek' gigabit Ethernet PHYs may fail to downshift to 100Mbps. (If partner 10G devices' downshift mechanism stops at 1G) This patch extends our 1G TX/RX link pulse time so that we can still link up with those 10G devices.
