From 12f3467b0d28369d3add7a0deb65fdac9b503c90 Mon Sep 17 00:00:00 2001 From: Amelie Delaunay Date: Thu, 24 Sep 2020 11:00:45 +0200 Subject: usb: typec: add typec_find_pwr_opmode This patch adds a function that converts power operation mode string into power operation mode value. It is useful to configure power operation mode through device tree property, as power capabilities may be linked to hardware design.
