This usually worked because the clock was first enabled by the -bootloader, and left as such until the driver is probe, where it tries to -access the MBUS configuration registers before enabling the clock. - -Things get messy when EPROBE_DEFER is involved during the probe, since as part -of its error path, the driver will rightfully disable the clock. When the -driver will be reprobed, it will retry to access the MBUS registers, but this -time with the clock disabled, which hangs forever. - -Fix this by running the quirks after the clock has been enabled by the driver. - -Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com> -Cc: <stable@vger.kernel.org> # v3.16+ -Signed-off-by: Mathias Nyman <mathias.nyman@linux.intel.com> -Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> - ---- a/drivers/usb/host/xhci-plat.c -+++ b/drivers/usb/host/xhci-plat.c -@@ -87,15 +87,6 @@ static int xhci_plat_probe(struct platfo - if (!res) - return -ENODEV; - -- if (of_device_is_compatible(pdev->dev.of_node, -- "marvell,armada-375-xhci") || -- of_device_is_compatible(pdev->dev.of_node, -- "marvell,armada-380-xhci")) { -- ret = xhci_mvebu_mbus_init_quirk(pdev); -- if (ret) -- return ret; -- } -- - /* Initialize dma_mask and coherent_dma_mask to 32-bits */ - ret = dma_set_coherent_mask(&pdev->dev, DMA_BIT_MASK(32)); - if (ret) -@@ -129,6 +120,15 @@ static int xhci_plat_probe(struct platfo - goto put_hcd; - } - -+ if (of_device_is_compatible(pdev->dev.of_node, -+ "marvell,armada-375-xhci") || -+ of_device_is_compatible(pdev->dev.of_node, -+ "marvell,armada-380-xhci")) { -+ ret = xhci_mvebu_mbus_init_quirk(pdev); -+ if (ret) -+ return ret; -+ } -+ - ret = usb_add_hcd(hcd, irq, IRQF_SHARED); - if (ret) - goto disable_clk; |
