Subject: [PATCH RFC net-next 0/7] net: stmmac: cleanup transmit clock setting
Date: Tue, 18 Feb 2025 11:14:39 +0000	[thread overview]
Message-ID: <Z7RrnyER5ewy0f3T@shell.armlinux.org.uk> (raw)

Hi,

A lot of stmmac platform code which sets the transmit clock is very
similar - they decode the speed to the clock rate (125, 25 or 2.5 MHz)
and then set a clock to that rate.

The DWMAC core appears to have a clock input for the transmit section
called clk_tx_i which requires this rate.

This series moves the code which sets this clock into the core stmmac
code.

Patch 1 adds a hook that platforms can use to configure the clock rate.
Patch 2 adds a generic implementation.
Patches 3 through 7 convert the easy-to-convert platforms to use this
new infrastructure.
