Subject: [PATCH v3 2/9] net: arc_emac: add phy reset is optional for device tree
Date: Mon, 14 Mar 2016 16:01:53 +0800 [thread overview]
Message-ID: <1457942520-12859-3-git-send-email-wxt@rock-chips.com> (raw)
In-Reply-To: <1457942520-12859-1-git-send-email-wxt-TNX95d0MmH7DzftRWevZcw@public.gmane.org>
This patch adds the following property for arc_emac.
1) phy-reset-gpios:
The phy-reset-gpio is an optional property for arc emac device tree boot.
Change the binding document to match the driver code.
2) phy-reset-duration:
Different boards may require different phy reset duration. Add property
phy-reset-duration for device tree probe, so that the boards that need
a longer reset duration can specify it in their device tree.
Anyway, we can add the above property for arc emac.
