Subject: [PATCH 1/3] mfd: cros: add charger port count command definition
Date:   Tue, 29 May 2018 20:17:02 -0700
Message-Id: <20180530031704.18597-2-fparent@baylibre.com>
In-Reply-To: <20180530031704.18597-1-fparent@baylibre.com>
References: <20180530031704.18597-1-fparent@baylibre.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

A new more command has been added to the ChromeOS embedded controller
that allows to get the number of charger port count. Unlike
EC_CMD_USB_PD_PORTS, this new command also includes the dedicated
port if present.

This command will be used to expose the dedicated charger port
in the ChromeOS charger driver.
