These patches introduce the MediaTek USB3 dual-role controller
driver.
The driver can be configured as Dual-Role Device (DRD),
Peripheral Only and Host Only (xHCI) modes. It works well
with Mass Storage, RNDIS and g_zero on FS/HS and SS. And it is
tested on MT8173 platform which only contains USB2.0 device IP,
and on MT6290 platform which contains USB3.0 device IP.
Change in v7:
1. split dual-role driver into four patchs
2. remove QMU done tasklet
3. add a bool in xhci_hcd_mtk to signal absence of IPPC
Change in v6:
1. handle endianness of GPD and SETUP data
2. remove dummy error log and return suitable error number
3. cancel delay work when deregiseter driver
Change in v5:
1. modify some comments
2. rename some unsuitable variables
3. add reg-names property for host node
4. add USB_MTU3_DEBUG to control debug messages
Change in v4:
1. fix build errors on non-mediatek platforms
2. provide manual dual-role switch via debugfs instead of sysfs
Change in v3:
1. fix some typo error
2. rename mtu3.txt to mt8173-mtu3.txt
Change in v2:
1. modify binding docs according to suggestions
2. modify some comments and remove some dummy blank lines
3. fix memory leakage
