ENGR00161314-1 mx6q usb-host: add hsic support
MSL part
Add HSIC support for Host2 and Host3, for HSIC mode, there
is not usb phy needed, the usb device is always at the board
- Validation hardware: iMX6Q Validation Port Card and Re-worked
Rev X3 board, for hardware rework detail, contact Ken Sun (b03826)
- Validation device: HSIC interface SMSC HUB(USB4640) and Host 3.
Host 2 is coding finishes, but not verified due to hardware limitation.
- Pin Conflict with Ethernet, order to use HSIC, the user need
disable ethernet function at both u-boot and linux kernel.
For u-boot: please undefine CONFIG_MXC_FEC at your board config file
For kernel: please define CONFIG_USB_EHCI_ARC_HSIC, the entry is:
Device Drivers---> USB support---> Support HSIC Host controller
for Freescale SoC
- Suspend/resume and wakeup are not supported due to IC issues,
these IC issues will be fixed at TO1.1 for i.mx6, software will
add these support after receiving TO1.1 chip.
