[PATCH linux dev-5.3 06/15] pinctrl: aspeed-g6: Add AST2600 I3C1 and I3C2 pinmux config

Andrew Jeffery andrew at aj.id.au
Thu Sep 26 23:35:59 AEST 2019


From: Johnny Huang <johnny_huang at aspeedtech.com>

These pins only expose a single function but are not fixed-function as
their I3C capability can be disabled.
