On Colibri Vybrid we provide the GPIO 102 for this very same purpose. Signed-off-by: Sanchayan Maity --- Changes since v1: Move the GPIO request call to the board_init function as all further calls to board_usb_phy_mode will actually result in the gpio_request failing. --- board/toradex/colibri_vf/colibri_vf.c | 22 +++++++++++++++++++++- 1 file changed, 21 insertions(+), 1 deletion(-) diff --git a/board/toradex/colibri_vf/colibri_vf.c b/board/toradex/colibri_vf/colibri_vf.c index a6d1c5b..69274e5 100644 --- a/board/toradex/colibri_vf/colibri_vf.c +++ b/board/toradex/colibri_vf/colibri_vf.c @@ -34,6 +34,7 @@ DECLARE_GLOBAL_DATA_PTR; PAD_CTL_DSE_50ohm | PAD_CTL_OBE_IBE_ENABLE) #define USB_PEN_GPIO 83 +#define USB_CDET_GPIO 102 static struct ddrmc_cr_setting colibri_vf_cr_settings[] = { /* levelling */ @@ -92,6 +93,7 @@ static struct ddrmc_cr_setting colibri_vf_cr_settings[] = { static const iomux_v3_cfg_t usb_pads[] = { VF610_PAD_PTD4__GPIO_83, + VF610_PAD_PTC29__GPIO_102, }; int dram_init(void) @@ -280,7 +282,6 @@ static void setup_iomux_gpio(void) VF610_PAD_PTB23__GPIO_93, VF610_PAD_PTB26__GPIO_96, VF610_PAD_PTB28__GPIO_98, - VF610_PAD_PTC29__GPIO_102, VF610_PAD_PTC30__GPIO_103, VF610_PAD_PTA7__GPIO_134, }; @@ -509,6 +510,10 @@ int board_init(void) setbits_le32(&scsc->sosc_ctr, SCSC_SOSC_CTR_SOSC_EN); +#ifdef CONFIG_USB_EHCI_VF + gpio_request(USB_CDET_GPIO, "usb-cdet-gpio"); +#endif + return 0; } @@ -554,4 +559,19 @@ int board_ehci_hcd_init(int port) } return 0; } + +int board_usb_phy_mode(int port) +{ + switch (port) { + case 0: + return gpio_get_value(USB_CDET_GPIO); + break; + case 1: + return 0; + break; + default: + return 0; + break; + } +} #endif -- 2.6.2
