From: Keshava Munegowda <Keshava_mgowda@xxxxxx> usbhs_disable function was invoking clk_enable() instead of clk_disable(), thus only increasing the clock usage counter and preventing this particular clock from being ever turned off. Because of this, the power domain of omap4 the USB Host subsystem would never reach lower power states.This patch calls clk_disable() in usbhs_disable function Signed-off-by: Keshava Munegowda <keshava_mgowda@xxxxxx> --- drivers/mfd/omap-usb-host.c | 4 ++-- 1 files changed, 2 insertions(+), 2 deletions(-) diff --git a/drivers/mfd/omap-usb-host.c b/drivers/mfd/omap-usb-host.c index 1717144..29601e7 100644 --- a/drivers/mfd/omap-usb-host.c +++ b/drivers/mfd/omap-usb-host.c @@ -998,9 +998,9 @@ static void usbhs_disable(struct device *dev) if (is_omap_usbhs_rev2(omap)) { if (is_ehci_tll_mode(pdata->port_mode[0])) - clk_enable(omap->usbtll_p1_fck); + clk_disable(omap->usbtll_p1_fck); if (is_ehci_tll_mode(pdata->port_mode[1])) - clk_enable(omap->usbtll_p2_fck); + clk_disable(omap->usbtll_p2_fck); clk_disable(omap->utmi_p2_fck); clk_disable(omap->utmi_p1_fck); } -- 1.6.0.4 -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
