* sunxi: H3: Do not clear usb companion clk-gate / reset on removeHans de Goede2016-04-12-3/+7
| | | | | | | | | | | | | | | | | On the H3 we need to enable the clk and de-assert the reset of the companion to be able to talk to the actual usb host controller. Before this commit we were also disabling the companion clk-gate / asserting its reset on remove, causing the later remove callback of the companion itself to (sometimes) fail with: ERROR: USB HC reset timed out! This commit fixes this by not disabling the companion's clk-gate nor asserting its reset on remove. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Ian Campbell <ijc@hellion.org.uk>

* sunxi: Fix 2nd usb controller on sun4i/sun7i no longer workingHans de Goede2016-03-23-3/+12
| | | | | | | | | | The 2nd usb controller on sun4i/sun7i has its base address 0x8000 bytes from the 1st one, rather then 0x1000. Also the ahb clk gates are interleaved with the ohci clk-gates introducing a hole between the clks for usb1 and usb2.

* sunxi: usb-phy: Never power off the usb portsHans de Goede2015-08-08-1/+0
| | | | | | | | | | | | | | | | | | | | | USB devices are not really designed to get the power bounced off and on at them. Esp. USB powered harddisks do not like this. Currently we power off the USB ports both on a "usb reset" and when booting the kernel, causing the usb-power to bounce off and then back on again. This patch removes the powering off calls, fixing the undesirable power bouncing. Note this requires some special handling for the OTG port: 1) We must skip the external vbus check if we've already enabled our own vbus to avoid false positives 2) If on an usb reset we no longer detect that the id-pin is grounded, turn off vbus as that means an external vbus may be present now Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Ian Campbell <ijc@hellion.org.uk>
* sunxi: ohci: Add ohci usb host controller supportHans de Goede2015-05-14-0/+104
This commit adds support for the OHCI companion controller, which makes usb-1 devices directly plugged into to usb root port work. Note for now this switches usb-keyboard support for sunxi back from int-queue support to the old interrupt polling method. Adding int-queue support to the ohci code and switching back to int-queue support is in the works.
