Marek Behún bf991fa357 kernel: 5.10: Backport pending Armada 3720 comphy patches
Backport 5 pending patches [1] for Armada 3720 comphy driver and one
patch for device tree, applied to mvebu-dt64, but pending to appear in
Linus' tree [2].

These patches makes the driver work correctly even with older, buggy
versions of TF-A firmware.

Subject: [PATCH] arm64: dts: marvell: armada-37xx: Add xtal clock to comphy
node
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Kernel driver phy-mvebu-a3700-comphy.c needs to know the rate of the
reference xtal clock. So add missing xtal clock source into comphy device
tree node. If the property is not present, the driver defaults to 25 MHz
xtal rate (which, as far as we know, is used by all the existing boards).
