-Subject: usb: XHCI: platform: Move the Marvell quirks after the enabling the
- clocks
-
-The commit 973747928514 ("usb: host: xhci-plat: add support for the Armada
-375/38x XHCI controllers") extended the xhci-plat driver to support the Armada
-375/38x SoCs, mostly by adding a quirk configuring the MBUS window.
-
-However, that quirk was run before the clock the controllers needs has been
-enabled. 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.
