There is now a proper phy driver for the DA8xx SoC USB PHY. This adds the platform device declarations needed to use it.
Signed-off-by: David Lechner <[email protected]> --- Updated this patch so that it applies/builds cleanly before "ARM: davinci: da8xx: add usb phy clocks" since that patch now uses da8xx_usb_phy from this patch. arch/arm/mach-davinci/board-da830-evm.c | 22 +++++++--------------- arch/arm/mach-davinci/board-omapl138-hawk.c | 5 +++++ arch/arm/mach-davinci/include/mach/da8xx.h | 1 + arch/arm/mach-davinci/usb-da8xx.c | 11 +++++++++++ 4 files changed, 24 insertions(+), 15 deletions(-) diff --git a/arch/arm/mach-davinci/board-da830-evm.c b/arch/arm/mach-davinci/board-da830-evm.c index 2a96b40..829f68d 100644 --- a/arch/arm/mach-davinci/board-da830-evm.c +++ b/arch/arm/mach-davinci/board-da830-evm.c @@ -26,7 +26,6 @@ #include <linux/platform_data/mtd-davinci.h> #include <linux/platform_data/mtd-davinci-aemif.h> #include <linux/platform_data/spi-davinci.h> -#include <linux/platform_data/usb-davinci.h> #include <linux/mfd/da8xx-cfgchip.h> #include <asm/mach-types.h> @@ -111,7 +110,7 @@ static __init void da830_evm_usb_init(void) int ret; /* - * Set up USB clock/mode in the CFGCHIP2 register. + * Set up USB clock in the CFGCHIP2 register. * FYI: CFGCHIP2 is 0x0000ef00 initially. */ cfgchip2 = __raw_readl(DA8XX_SYSCFG0_VIRT(DA8XX_CFGCHIP2_REG)); @@ -128,22 +127,15 @@ static __init void da830_evm_usb_init(void) cfgchip2 &= ~CFGCHIP2_USB1PHYCLKMUX; cfgchip2 |= CFGCHIP2_USB2PHYCLKMUX; - /* - * We have to override VBUS/ID signals when MUSB is configured into the - * host-only mode -- ID pin will float if no cable is connected, so the - * controller won't be able to drive VBUS thinking that it's a B-device. - * Otherwise, we want to use the OTG mode and enable VBUS comparators. - */ - cfgchip2 &= ~CFGCHIP2_OTGMODE; -#ifdef CONFIG_USB_MUSB_HOST - cfgchip2 |= CFGCHIP2_FORCE_HOST; -#else - cfgchip2 |= CFGCHIP2_SESENDEN | CFGCHIP2_VBDTCTEN; -#endif - __raw_writel(cfgchip2, DA8XX_SYSCFG0_VIRT(DA8XX_CFGCHIP2_REG)); /* USB_REFCLKIN is not used. */ + + ret = da8xx_register_usb_phy(); + if (ret) + pr_warn("%s: USB PHY registration failed: %d\n", + __func__, ret); + ret = davinci_cfg_reg(DA830_USB0_DRVVBUS); if (ret) pr_warn("%s: USB 2.0 PinMux setup failed: %d\n", __func__, ret); diff --git a/arch/arm/mach-davinci/board-omapl138-hawk.c b/arch/arm/mach-davinci/board-omapl138-hawk.c index 70ebbba..0fd2ef1 100644 --- a/arch/arm/mach-davinci/board-omapl138-hawk.c +++ b/arch/arm/mach-davinci/board-omapl138-hawk.c @@ -259,6 +259,11 @@ static __init void omapl138_hawk_usb_init(void) cfgchip2 |= CFGCHIP2_REFFREQ_24MHZ; __raw_writel(cfgchip2, DA8XX_SYSCFG0_VIRT(DA8XX_CFGCHIP2_REG)); + ret = da8xx_register_usb_phy(); + if (ret) + pr_warn("%s: USB PHY registration failed: %d\n", + __func__, ret); + ret = gpio_request_one(DA850_USB1_VBUS_PIN, GPIOF_DIR_OUT, "USB1 VBUS"); if (ret < 0) { diff --git a/arch/arm/mach-davinci/include/mach/da8xx.h b/arch/arm/mach-davinci/include/mach/da8xx.h index 2f6fe2f0..5e07d06 100644 --- a/arch/arm/mach-davinci/include/mach/da8xx.h +++ b/arch/arm/mach-davinci/include/mach/da8xx.h @@ -89,6 +89,7 @@ int da850_register_edma(struct edma_rsv_info *rsv[2]); int da8xx_register_i2c(int instance, struct davinci_i2c_platform_data *pdata); int da8xx_register_spi_bus(int instance, unsigned num_chipselect); int da8xx_register_watchdog(void); +int da8xx_register_usb_phy(void); int da8xx_register_usb20(unsigned mA, unsigned potpgt); int da8xx_register_usb11(struct da8xx_ohci_root_hub *pdata); int da8xx_register_emac(void); diff --git a/arch/arm/mach-davinci/usb-da8xx.c b/arch/arm/mach-davinci/usb-da8xx.c index f141f51..4bb1903 100644 --- a/arch/arm/mach-davinci/usb-da8xx.c +++ b/arch/arm/mach-davinci/usb-da8xx.c @@ -3,6 +3,7 @@ */ #include <linux/dma-mapping.h> #include <linux/init.h> +#include <linux/phy/phy.h> #include <linux/platform_data/usb-davinci.h> #include <linux/platform_device.h> #include <linux/usb/musb.h> @@ -15,6 +16,16 @@ #define DA8XX_USB0_BASE 0x01e00000 #define DA8XX_USB1_BASE 0x01e25000 +static struct platform_device da8xx_usb_phy = { + .name = "da8xx-usb-phy", + .id = -1, +}; + +int __init da8xx_register_usb_phy(void) +{ + return platform_device_register(&da8xx_usb_phy); +} + #if IS_ENABLED(CONFIG_USB_MUSB_HDRC) static struct musb_hdrc_config musb_config = { -- 2.7.4
