From 7034d8b711398d5627fab5fe787fc33e24d76c48 Mon Sep 17 00:00:00 2001 From: Fabien Parent Date: Sat, 5 May 2018 13:59:00 +0200 Subject: charge_manager: add host cmd to get port count The kernel is only able to know the number of USB PD port through EC_CMD_USB_PD_PORTS, but the kernel needs also to be able to know that there is a dedicated port. Add a host command that will return the total number of charge port (USB PD + BJ). BRANCH=None BUG=chromium:841944 TEST=Called command from kernel driver and checked that the port count was the expected value.
