* sunxi: musb: Return early on VBUS GPIO error instead of on a positive valuePaul Kocialkowski2015-03-21-1/+1
| | | | | | | | | This allows printing the error message when VBUS is detected, as it would with AXP VBUS detect. Signed-off-by: Paul Kocialkowski <contact@paulk.fr> Acked-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Hans de Goede <hdegoede@redhat.com>
* sunxi: musb: Support checking VBUS using AXP221 PMICChen-Yu Tsai2015-03-10-14/+38
| | | | | | | | | | | | | | | | This enables the musb glue layer to use the AXP221's VBUS detection function to check for VBUS. This fixes otg support on the A23 q8h tablets. Note that u-boot never calls musb_shutdown(), so once VBUS is enabled, it is never disabled until the system is powered off, or the OS does so. This can be used to our advantage to keep VBUS powered into the OS, where support for AXP221 is not available yet.

* sunxi: musb: Check Vbus-det before enabling otg port powerHans de Goede2015-02-21-0/+29
| | | | | | | | | | | | Sending out 5V when there is a charger connected to the otg port is not a good idea, so check for this and error out. Note this commit currently breaks otg support on the q8h tablets, as we need to do some magic with the pmic there to get vbus info, this is deliberate (better safe then sorry), fixing this is on my TODO list.

* sunxi: otg: Fix peripheral modeHans de Goede2015-02-16-12/+1
| | | | | | | | Peripheral mode needs us to signal vusb high to the phy for it to work, just like the host mode does. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Ian Campbell <ijc@hellion.org.uk>
* musb-new: Add sunxi musb controller supportHans de Goede2015-01-18-0/+279
This is based on Jussi Kivilinna's work for the linux-sunxi-3.4 kernel to use the kernels musb driver instead of Allwinners own custom driver. Signed-off-by: Hans de Goede <hdegoede@redhat.com>
