Subject: [PATCH 5.10 05/21] net: stmmac: add clocks management for gmac driver
Date: Fri, 19 Nov 2021 18:37:40 +0100	[thread overview]
Message-ID: <20211119171444.062394939@linuxfoundation.org> (raw)
In-Reply-To: <20211119171443.892729043@linuxfoundation.org>

From: Joakim Zhang <qiangqing.zhang@nxp.com>

commit 5ec55823438e850c91c6b92aec93fb04ebde29e2 upstream.

This patch intends to add clocks management for stmmac driver:

If CONFIG_PM enabled:
1. Keep clocks disabled after driver probed.
2. Enable clocks when up the net device, and disable clocks when down
the net device.

If CONFIG_PM disabled:
Keep clocks always enabled after driver probed.

Note:
1. It is fine for ethtool, since the way of implementing ethtool_ops::begin
in stmmac is only can be accessed when interface is enabled, so the clocks
are ticked.
2. The MDIO bus has a different life cycle to the MAC, need ensure
clocks are enabled when _mdio_read/write() need clocks, because these
functions can be called while the interface it not opened.

Stable backport notes:
When run below command to remove ethernet driver on
stratix10 platform, there will be warning trace as below:

$ cd /sys/class/net/eth0/device/driver/
$ echo ff800000.ethernet > unbind

This issue is introduced by introducing upstream commit 8f269102baf7
("net: stmmac: disable clocks in stmmac_remove_config_dt()")

But in latest mainline kernel, there is no this issue. Because this
patch improved clocks management for stmmac driver.
Therefore, backport it and its fixing patches to stable kernel v5.10.
