[PATCH AUTOSEL 5.13 033/189] net: mdio: provide shim implementation of devm_of_mdiobus_register

[Sasha Levin]

From: Vladimir Oltean <olteanv@gmail.com>

[ Upstream commit 86544c3de6a2185409c5a3d02f674ea223a14217 ]

Similar to the way in which of_mdiobus_register() has a fallback to the
non-DT based mdiobus_register() when CONFIG_OF is not set, we can create
a shim for the device-managed devm_of_mdiobus_register() which calls
devm_mdiobus_register() and discards the struct device_node *.

In particular, this solves a build issue with the qca8k DSA driver which
uses devm_of_mdiobus_register and can be compiled without CONFIG_OF.

[PATCH AUTOSEL 5.13 189/189] MIPS: CI20: Reduce clocksource to 750 kHz.

[Sasha Levin]

From: 周琰杰 (Zhou Yanjie) <zhouyanjie@wanyeetech.com>

[ Upstream commit 23c64447b3538a6f34cb38aae3bc19dc1ec53436 ]

The original clock (3 MHz) is too fast for the clocksource,
there will be a chance that the system may get stuck.
