Subject: [PATCH v4 1/2] mfd: google,cros-ec: add DT bindings for a baseboard's switch device
Date: Mon, 12 Apr 2021 19:30:19 +0800 [thread overview]
Message-ID: <20210412113020.2724134-2-ikjn@chromium.org> (raw)
In-Reply-To: <20210412113020.2724134-1-ikjn@chromium.org>
This is for ChromeOS tablets which have a 'cros_cbas' switch device
in the "Whiskers" base board. This device can be instantiated only by
device tree on ARM platforms. ChromeOS EC doesn't provide a way to
probe the device.
Signed-off-by: Ikjoon Jang <ikjn@chromium.org>

Changes in v4:
Define cros-cbase bindings inside google,cros-ec.yaml instead of
a seperated binding document.
