Subject: [PATCH RESEND v4 4/4] ARM: tegra: acer-a500: Add Embedded Controller
Date: Mon, 26 Oct 2020 02:01:53 +0300 [thread overview]
Message-ID: <20201025230153.11729-5-digetx@gmail.com> (raw)
In-Reply-To: <20201025230153.11729-1-digetx@gmail.com>
This patch adds device-tree node for the Embedded Controller which is
found on the Picasso board. The Embedded Controller itself is ENE KB930,
it provides functions like battery-gauge/LED/GPIO/etc and it uses firmware
that is specifically customized for the Acer A500 device.
