Hi,
I try to use USB HSIC port C of sama5d2 to communicate with USB3503 USB HUB. I have enabled ehci layer in device tree and init USB3503 chip with driver. HSIC communication is not enabled (HSIC_EN of UHPHS_INSNREG08 register equal to 0).
I try to force this bit in EHCI driver (there are communication on HSIC but lot of errors protocol error)
Does Atmel EHCI driver supports HSIC communication ? Are there any information about HSIC integration in driver or a patch to apply to kernel ?
Thanks,
Sébastien Corbeau
