* [PATCH v2 0/3] ARM: mvebu: Enable XHCI on the Armada 385 AP @ 2015-01-19 13:01 Maxime Ripard 2015-01-19 13:01 ` [PATCH v2 1/3] usb: XHCI: platform: Move the Marvell quirks after the enabling the clocks Maxime Ripard ` (3 more replies) 0 siblings, 4 replies; 21+ messages in thread From: Maxime Ripard @ 2015-01-19 13:01 UTC (permalink / raw) To: linux-arm-kernel Hi all, This serie enables the Armada 385 AP XHCI controller. Since the controller uses a GPIO-controlled VBUS, we used the phy-generic driver, and made the needed additions to the xhci-plat driver to retrieve a USB phy. Unfortunately, some glitches were also found along the way, mostly because of the probe deferring that was introduced by this phy retrieval. Since the introduction of the Armada 38x support in 3.16, the driver was attempting to write into registers while the clock wasn't enabled yet. This was working because the bootloader left it enabled, but in the case of a deferred probing, the clock would have been disabled by the error path of our driver, and this would fail. This should go in 3.19, and any stable kernel for 3.16+. The two patches remaining are "regular" patches, and are aimed at 3.20. The last patch depend on my previous serie to introduce support for the the A385 AP board. Thanks, Maxime Changes from v1: - Removed the patch 1 that fixes the deferred probing that was merged - Fixed the error path of the mvebu quirks code to avoid leaking a clock reference and the main HCD. - Removed the extra PHY field private to the struct xhci, and used the usb_phy field in the main HCD instead - Fixed the error path of the phy retrieval code in order to avoid leaving the phy up if an error was to happen, or the remove callback to be called.

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.

Ah, so you were talking only about the first patch. My bad. > The other two patches, 2/3 and 3/3 you said were "regual" patches > (for usb-next?), Indeed, at least for patch 2. > Andrew said he can take 3/3 and wondered if 2/3 and 3/3 need to go > together? Patch 3 doesn't need to be merged through the same tree, so I guess it's totally fine if 2 goes through USB and 3 through arm-soc. > It doesn't matter for me, I can take 2/3 if you like, but I'd prefer if someone > with more USB PHY insight could ack it first.

There should be no merge dependency, but merging the third patch alone will probably result on a boot breakage. I don't think it really matters though, since this is a new board, so I guess it can go through the USB-PHY tree.
