From 30340cb4f222e6227ed9c8b558c1635b741f3683 Mon Sep 17 00:00:00 2001 From: Hake Huang Date: Fri, 30 Dec 2011 21:14:57 +0800 Subject: ENGR00171115 add fec support in mx6q sabreauto board Add fec support for sabreauto board Need hardware rework: 1. Add R450 10.0k 2. Remove R1105 1k 3. short Pin 1,2 of u516, will impact CAN1 Signed-off-by: Hake Huang --- board/freescale/mx6q_sabreauto/mx6q_sabreauto.c | 61 ++++++++++--------------- 1 file changed, 25 insertions(+), 36 deletions(-) (limited to 'board/freescale') diff --git a/board/freescale/mx6q_sabreauto/mx6q_sabreauto.c b/board/freescale/mx6q_sabreauto/mx6q_sabreauto.c index 4334f00..8d5e480 100644 --- a/board/freescale/mx6q_sabreauto/mx6q_sabreauto.c +++ b/board/freescale/mx6q_sabreauto/mx6q_sabreauto.c @@ -92,6 +92,21 @@ static struct fb_videomode lvds_xga = { vidinfo_t panel_info; #endif +static void set_gpio_output_val(unsigned base, unsigned mask, unsigned val) +{ + unsigned reg = readl(base + GPIO_DR); + if (val & 1) + reg |= mask; /* set high */ + else + reg &= ~mask; /* clear low */ + writel(reg, base + GPIO_DR); + + reg = readl(base + GPIO_GDIR); + reg |= mask; /* configure GPIO line as output */ + writel(reg, base + GPIO_GDIR); +} + + static inline void setup_boot_device(void) { uint soc_sbmr = readl(SRC_BASE_ADDR + 0x4); @@ -766,23 +781,18 @@ static int phy_write(char *devname, unsigned char addr, unsigned char reg, int mx6_rgmii_rework(char *devname, int phy_addr) { - unsigned short val; - /* To enable AR8031 ouput a 125MHz clk from CLK_25M */ - phy_write(devname, phy_addr, 0xd, 0x7); - phy_write(devname, phy_addr, 0xe, 0x8016); - phy_write(devname, phy_addr, 0xd, 0x4007); - phy_read(devname, phy_addr, 0xe, &val); + /* enable master mode, 1000 Base-T capable */ + phy_write(devname, phy_addr, 0x9, 0x1f00); - val &= 0xffe3; - val |= 0x18; - phy_write(devname, phy_addr, 0xe, val); + /* min rx data delay */ + phy_write(devname, phy_addr, 0x0b, 0x8105); + phy_write(devname, phy_addr, 0x0c, 0x0000); - /* introduce tx clock delay */ - phy_write(devname, phy_addr, 0x1d, 0x5); - phy_read(devname, phy_addr, 0x1e, &val); - val |= 0x0100; - phy_write(devname, phy_addr, 0x1e, val); + /* max rx/tx clock delay, min rx/tx control delay */ + phy_write(devname, phy_addr, 0x0b, 0x8104); + phy_write(devname, phy_addr, 0x0c, 0xf0f0); + phy_write(devname, phy_addr, 0x0b, 0x104); return 0; } @@ -803,37 +813,16 @@ iomux_v3_cfg_t enet_pads[] = { MX6Q_PAD_RGMII_RD2__ENET_RGMII_RD2, MX6Q_PAD_RGMII_RD3__ENET_RGMII_RD3, MX6Q_PAD_RGMII_RX_CTL__ENET_RGMII_RX_CTL, - MX6Q_PAD_GPIO_0__CCM_CLKO, - MX6Q_PAD_GPIO_3__CCM_CLKO2, }; void enet_board_init(void) { unsigned int reg; - iomux_v3_cfg_t enet_reset = - (MX6Q_PAD_KEY_ROW4__GPIO_4_15 & - ~MUX_PAD_CTRL_MASK) | - MUX_PAD_CTRL(0x84); mxc_iomux_v3_setup_multiple_pads(enet_pads, ARRAY_SIZE(enet_pads)); + set_gpio_output_val(GPIO6_BASE_ADDR, (1 << 24), 1); - mxc_iomux_v3_setup_pad(enet_reset); - - /* phy reset: gpio4-15 */ - reg = readl(GPIO4_BASE_ADDR + 0x0); - reg &= ~0x8000; - writel(reg, GPIO4_BASE_ADDR + 0x0); - - reg = readl(GPIO4_BASE_ADDR + 0x4); - reg |= 0x8000; - writel(reg, GPIO4_BASE_ADDR + 0x4); - - udelay(500); - - reg = readl(GPIO4_BASE_ADDR + 0x0); - reg |= 0x8000; - writel(reg, GPIO4_BASE_ADDR + 0x0); } int checkboard(void) -- cgit v1.1
