Subject: [PATCH v1 1/2] doc: dt-binding: mxs-usb-phy: fix fsl,tx-cal-45-dn-ohms max and min value
Date: Mon, 29 Aug 2022 10:31:23 -0500 [thread overview]
Message-ID: <20220829153124.2791210-1-Frank.Li@nxp.com> (raw)
According to spec:
0000 +19.95%
....
1111 -21.68%
45 * (1 + 19.95%) = 53.9775
45 * (1 - 21.68%) = 35.244
Chanege fsl,tx-cal-45-dn-ohms and fsl,tx-cal-45-dp-ohms range to [35-54]
from [30-55]
