Typically there is some additional configuration +needed to tell the USB device to generate the wake event when +suspended but this varies with the different USB device classes. +For example, on USB Ethernet dongles, ethtool should be used to +enable the magic packet wake functionality in the dongle. +NOTE: This requires that the "power/wakeup" sysfs entry for +the USB device generating the wakeup be set to "enabled". + +This functionality requires a special hardware sideband path that +will trigger the AON_PM_L2 interrupt needed to wake the system from +S2 even though the USB host controllers are in IDDQ (low power state) +and most USB related clocks are shut off. For the sideband signaling +to work we need to leave the usbx_freerun clock running, but this +clock consumes very little power by design. There's a bug in the +XHCI wake hardware so only EHCI/OHCI wake is currently supported. + +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.c | 17 +++++++++ + drivers/phy/broadcom/phy-brcm-usb-init.h | 1 + + drivers/phy/broadcom/phy-brcm-usb.c | 48 ++++++++++++++++++++++-- + 3 files changed, 63 insertions(+), 3 deletions(-) + +--- a/drivers/phy/broadcom/phy-brcm-usb-init.c ++++ b/drivers/phy/broadcom/phy-brcm-usb-init.c +@@ -58,6 +58,8 @@ + #define USB_CTRL_USB_PM_SOFT_RESET_MASK 0x40000000 /* option */ + #define USB_CTRL_USB_PM_USB20_HC_RESETB_MASK 0x30000000 /* option */ + #define USB_CTRL_USB_PM_USB20_HC_RESETB_VAR_MASK 0x00300000 /* option */ ++#define USB_CTRL_USB_PM_RMTWKUP_EN_MASK 0x00000001 ++#define USB_CTRL_USB_PM_STATUS 0x38 + #define USB_CTRL_USB30_CTL1 0x60 + #define USB_CTRL_USB30_CTL1_PHY3_PLL_SEQ_START_MASK 0x00000010 + #define USB_CTRL_USB30_CTL1_PHY3_RESETB_MASK 0x00010000 +@@ -855,6 +857,10 @@ void brcm_usb_init_common(struct brcm_us + u32 reg;
