Subject: [PATCH v3 11/16] hw/net: cadence_gem: Add a new 'phy-addr' property
Date: Tue, 1 Sep 2020 09:39:06 +0800 [thread overview]
Message-ID: <1598924352-89526-12-git-send-email-bmeng.cn@gmail.com> (raw)
In-Reply-To: <1598924352-89526-1-git-send-email-bmeng.cn@gmail.com>
From: Bin Meng <bin.meng@windriver.com>
At present the PHY address of the PHY connected to GEM is hard-coded
to either 23 (BOARD_PHY_ADDRESS) or 0. This might not be the case for
all boards. Add a new 'phy-addr' property so that board can specify
the PHY address for each GEM instance.
Signed-off-by: Bin Meng <bin.meng@windriver.com>

(no changes since v2)
Changes in v2:
- change "phy-addr" default value to BOARD_PHY_ADDRESS
