For now we guard charger-based VBUS voltage measurement behind CONFIG_USB_PD_VBUS_DETECT_CHARGER. But we should be able to measure VBUS voltage by charger while detecting VBUS presence by other methods. BUG=b:67991345 BRANCH=none TEST=plug in guppy on Scarlet rev2, 'ectool usbpdpower' on console, and see VBUS is measured as 4975mV Change-Id: I94cada81159ea4b097001997e2444873ec2d8763 Signed-off-by: Philip Chen <philipchen@google.com> Reviewed-on: https://chromium-review.googlesource.com/789910 Commit-Ready: Philip Chen <philipchen@chromium.org> Tested-by: Philip Chen <philipchen@chromium.org> Reviewed-by: Aseda Aboagye <aaboagye@chromium.org>
