Subject: usb: typec: tcpci_rt1711h: Add rxdz_sel variable to struct rt1711h_chip_info
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=0f9df9662097c1ea3a9aa20aad5a818e6532de19;p=linux.git

usb: typec: tcpci_rt1711h: Add rxdz_sel variable to struct rt1711h_chip_info

The RT1715 needs 0.35V/0.75V rx threshold for rd/rp whereas it is 0.4V/0.7V
for RT1711H. Add rxdz_sel variable to struct rt1711h_chip_info for
handling this difference.
