When the PHY is put into suspend mode -the USB LDO powers down the PHY. This causes the MDIO to be -inaccessible and its registers reset to default. The fix is to -disable FSM. - -Signed-off-by: Al Cooper <alcooperx@gmail.com> -Reviewed-by: Florian Fainelli <f.fainelli@gmail.com> -Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com> ---- - drivers/phy/broadcom/phy-brcm-usb-init-synopsys.c | 9 +++++++++ - 1 file changed, 9 insertions(+) - ---- a/drivers/phy/broadcom/phy-brcm-usb-init-synopsys.c -+++ b/drivers/phy/broadcom/phy-brcm-usb-init-synopsys.c -@@ -56,6 +56,7 @@ - #define USB_PHY_PLL_LDO_CTL 0x08 - #define USB_PHY_PLL_LDO_CTL_AFE_CORERDY_MASK 0x00000004 - #define USB_PHY_UTMI_CTL_1 0x04 -+#define USB_PHY_UTMI_CTL_1_POWER_UP_FSM_EN_MASK 0x00000800 - #define USB_PHY_UTMI_CTL_1_PHY_MODE_MASK 0x0000000c - #define USB_PHY_UTMI_CTL_1_PHY_MODE_SHIFT 2 - #define USB_PHY_STATUS 0x20 -@@ -229,6 +230,14 @@ static void usb_init_common_7211b0(struc - - usb_init_common(params); - -+ /* -+ * Disable FSM, otherwise the PHY will auto suspend when no -+ * device is connected and will be reset on resume. -+ */ -+ reg = brcm_usb_readl(usb_phy + USB_PHY_UTMI_CTL_1); -+ reg &= ~USB_PHY_UTMI_CTL_1_POWER_UP_FSM_EN_MASK; -+ brcm_usb_writel(reg, usb_phy + USB_PHY_UTMI_CTL_1); -+ - usb2_eye_fix_7211b0(params); - } - |
