Signed-off-by: Chris Brandt --- v3: * changed 'if' to 'switch' * use rcar_gen3_set_host_mode() instead of writel() v2: * added braces to else statement * check if dr_mode is "host" --- drivers/phy/renesas/phy-rcar-gen3-usb2.c | 12 ++++++++++++ 1 file changed, 12 insertions(+) diff --git a/drivers/phy/renesas/phy-rcar-gen3-usb2.c b/drivers/phy/renesas/phy-rcar-gen3-usb2.c index 06e0fc804226..29da9c46ad9b 100644 --- a/drivers/phy/renesas/phy-rcar-gen3-usb2.c +++ b/drivers/phy/renesas/phy-rcar-gen3-usb2.c @@ -412,6 +412,18 @@ static int rcar_gen3_phy_usb2_init(struct phy *p) if (rcar_gen3_needs_init_otg(channel)) rcar_gen3_init_otg(channel); rphy->otg_initialized = true; + } else { + /* Not OTG, so dr_mode should be set in PHY node */ + switch (usb_get_dr_mode(channel->dev)) { + case USB_DR_MODE_HOST: + rcar_gen3_set_host_mode(channel, 1); + break; + case USB_DR_MODE_PERIPHERAL: + rcar_gen3_set_host_mode(channel, 0); + break; + default: + break; + } } rphy->initialized = true; -- 2.16.1
