Enable MUSB clocks before the xceiver resume is called. As soon as xceiver resume is called, xceiver communicates an interrupt to MUSB over ULPI bus and the interrupt handler crashes as the clocks are not enabled on going to resume. So enable the MUSB clocks so that its ready to handle interrupts from the xceiver Signed-off-by: Vikram Pandita <vikram.pandita@xxxxxx> --- drivers/usb/musb/omap2430.c | 9 +++++++-- 1 files changed, 7 insertions(+), 2 deletions(-) diff --git a/drivers/usb/musb/omap2430.c b/drivers/usb/musb/omap2430.c index ea7a798..67dabe1 100644 --- a/drivers/usb/musb/omap2430.c +++ b/drivers/usb/musb/omap2430.c @@ -286,13 +286,18 @@ int musb_platform_resume(struct musb *musb) if (!musb->clock) return 0; - otg_set_suspend(otg_get_transceiver(), 0); - + /* Keep MUSB clock enabled + * this is needed when phy xvr is enabled, MUSB gets + * an interrupt and system crashes. + * So enable clock before calling phy resume + */ if (musb->set_clock) musb->set_clock(musb->clock, 1); else clk_enable(musb->clock); + otg_set_suspend(otg_get_transceiver(), 0); + l = omap_readl(OTG_SYSCONFIG); l &= ~ENABLEWAKEUP; /* disable wakeup */ omap_writel(l, OTG_SYSCONFIG); -- 1.6.3.3.334.g916e1 -- 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
