From 476f7090bf49ecbed8ae5350547ae8ab5165d9e1 Mon Sep 17 00:00:00 2001 From: Philipp Tomsich Date: Fri, 24 Mar 2017 19:24:23 +0100 Subject: [PATCH] rockchip: pinctrl: rk3399: add GMAC (RGMII only) support To add GMAC (Gigabit Ethernet) support (limited to RGMII only at this point), we need support for additional pin-configuration. This commit adds the pinctrl support for GMAC in RGMII signalling mode: * adds a PERIPH_ID_GMAC and the mapping from IRQ number to PERIPH_ID * adds the required defines (in the GRF support) for configuring the GPIOC pins for RGMII * configures the RGMII pins (in GPIOC) when requested via pinctrl X-AffectedPlatforms: RK3399-Q7 Signed-off-by: Philipp Tomsich Acked-by: Simon Glass --- .../include/asm/arch-rockchip/grf_rk3399.h | 37 ++++++++++++++++ arch/arm/include/asm/arch-rockchip/periph.h | 1 + drivers/pinctrl/rockchip/pinctrl_rk3399.c | 42 +++++++++++++++++++ 3 files changed, 80 insertions(+) diff --git a/arch/arm/include/asm/arch-rockchip/grf_rk3399.h b/arch/arm/include/asm/arch-rockchip/grf_rk3399.h index 62d8496ca5..e709fdaad2 100644 --- a/arch/arm/include/asm/arch-rockchip/grf_rk3399.h +++ b/arch/arm/include/asm/arch-rockchip/grf_rk3399.h @@ -334,23 +334,60 @@ enum { GRF_SPI2TPM_CSN0 = 1, /* GRF_GPIO3A_IOMUX */ + GRF_GPIO3A0_SEL_SHIFT = 0, + GRF_GPIO3A0_SEL_MASK = 3 << GRF_GPIO3A0_SEL_SHIFT, + GRF_MAC_TXD2 = 1, + GRF_GPIO3A1_SEL_SHIFT = 2, + GRF_GPIO3A1_SEL_MASK = 3 << GRF_GPIO3A1_SEL_SHIFT, + GRF_MAC_TXD3 = 1, + GRF_GPIO3A2_SEL_SHIFT = 4, + GRF_GPIO3A2_SEL_MASK = 3 << GRF_GPIO3A2_SEL_SHIFT, + GRF_MAC_RXD2 = 1, + GRF_GPIO3A3_SEL_SHIFT = 6, + GRF_GPIO3A3_SEL_MASK = 3 << GRF_GPIO3A3_SEL_SHIFT, + GRF_MAC_RXD3 = 1, GRF_GPIO3A4_SEL_SHIFT = 8, GRF_GPIO3A4_SEL_MASK = 3 << GRF_GPIO3A4_SEL_SHIFT, + GRF_MAC_TXD0 = 1, GRF_SPI0NORCODEC_RXD = 2, GRF_GPIO3A5_SEL_SHIFT = 10, GRF_GPIO3A5_SEL_MASK = 3 << GRF_GPIO3A5_SEL_SHIFT, + GRF_MAC_TXD1 = 1, GRF_SPI0NORCODEC_TXD = 2, GRF_GPIO3A6_SEL_SHIFT = 12, GRF_GPIO3A6_SEL_MASK = 3 << GRF_GPIO3A6_SEL_SHIFT, + GRF_MAC_RXD0 = 1, GRF_SPI0NORCODEC_CLK = 2, GRF_GPIO3A7_SEL_SHIFT = 14, GRF_GPIO3A7_SEL_MASK = 3 << GRF_GPIO3A7_SEL_SHIFT, + GRF_MAC_RXD1 = 1, GRF_SPI0NORCODEC_CSN0 = 2, /* GRF_GPIO3B_IOMUX */ GRF_GPIO3B0_SEL_SHIFT = 0, GRF_GPIO3B0_SEL_MASK = 3 << GRF_GPIO3B0_SEL_SHIFT, + GRF_MAC_MDC = 1, GRF_SPI0NORCODEC_CSN1 = 2, + GRF_GPIO3B1_SEL_SHIFT = 2, + GRF_GPIO3B1_SEL_MASK = 3 << GRF_GPIO3B1_SEL_SHIFT, + GRF_MAC_RXDV = 1, + GRF_GPIO3B3_SEL_SHIFT = 6, + GRF_GPIO3B3_SEL_MASK = 3 << GRF_GPIO3B3_SEL_SHIFT, + GRF_MAC_CLK = 1, + GRF_GPIO3B4_SEL_SHIFT = 8, + GRF_GPIO3B4_SEL_MASK = 3 << GRF_GPIO3B4_SEL_SHIFT, + GRF_MAC_TXEN = 1, + GRF_GPIO3B5_SEL_SHIFT = 10, + GRF_GPIO3B5_SEL_MASK = 3 << GRF_GPIO3B5_SEL_SHIFT, + GRF_MAC_MDIO = 1, + GRF_GPIO3B6_SEL_SHIFT = 12, + GRF_GPIO3B6_SEL_MASK = 3 << GRF_GPIO3B6_SEL_SHIFT, + GRF_MAC_RXCLK = 1, + + /* GRF_GPIO3C_IOMUX */ + GRF_GPIO3C1_SEL_SHIFT = 2, + GRF_GPIO3C1_SEL_MASK = 3 << GRF_GPIO3C1_SEL_SHIFT, + GRF_MAC_TXCLK = 1, /* GRF_GPIO4B_IOMUX */ GRF_GPIO4B0_SEL_SHIFT = 0, diff --git a/arch/arm/include/asm/arch-rockchip/periph.h b/arch/arm/include/asm/arch-rockchip/periph.h index fa6069b350..239a27443a 100644 --- a/arch/arm/include/asm/arch-rockchip/periph.h +++ b/arch/arm/include/asm/arch-rockchip/periph.h @@ -38,6 +38,7 @@ enum periph_id { PERIPH_ID_SDMMC1, PERIPH_ID_SDMMC2, PERIPH_ID_HDMI, + PERIPH_ID_GMAC, PERIPH_ID_COUNT, diff --git a/drivers/pinctrl/rockchip/pinctrl_rk3399.c b/drivers/pinctrl/rockchip/pinctrl_rk3399.c index a74793aa48..507bec4a96 100644 --- a/drivers/pinctrl/rockchip/pinctrl_rk3399.c +++ b/drivers/pinctrl/rockchip/pinctrl_rk3399.c @@ -202,6 +202,39 @@ static void pinctrl_rk3399_sdmmc_config(struct rk3399_grf_regs *grf, int mmc_id) } } +#if CONFIG_IS_ENABLED(GMAC_ROCKCHIP) +static void pinctrl_rk3399_gmac_config(struct rk3399_grf_regs *grf, int mmc_id) +{ + rk_clrsetreg(&grf->gpio3a_iomux, + GRF_GPIO3A0_SEL_MASK | GRF_GPIO3A1_SEL_MASK | + GRF_GPIO3A2_SEL_MASK | GRF_GPIO3A3_SEL_MASK | + GRF_GPIO3A4_SEL_MASK | GRF_GPIO3A5_SEL_MASK | + GRF_GPIO3A6_SEL_MASK | GRF_GPIO3A7_SEL_MASK, + GRF_MAC_TXD2 << GRF_GPIO3A0_SEL_SHIFT | + GRF_MAC_TXD3 << GRF_GPIO3A1_SEL_SHIFT | + GRF_MAC_RXD2 << GRF_GPIO3A2_SEL_SHIFT | + GRF_MAC_RXD3 << GRF_GPIO3A3_SEL_SHIFT | + GRF_MAC_TXD0 << GRF_GPIO3A4_SEL_SHIFT | + GRF_MAC_TXD1 << GRF_GPIO3A5_SEL_SHIFT | + GRF_MAC_RXD0 << GRF_GPIO3A6_SEL_SHIFT | + GRF_MAC_RXD1 << GRF_GPIO3A7_SEL_SHIFT);
