Have you regenerated this list lately? The pinmux tool usually puts the
comment after the PADCONF entry. It also now also shows the pin number
in the comment which is nice:
AM33XX_IOPAD(0x88c, PIN_OUTPUT, MUX_MODE5) /* (V12) gpmc_clk.pr1_mdio_mdclk */
AM33XX_IOPAD(0x888, PIN_INPUT, MUX_MODE5) /* (T13) gpmc_csn3.pr1_mdio_data */
I'd recommend regenerating these nodes to match the latest pinmux tool output.

Is this needed? If you disable the CPSW MDIO node the pinmux should be unset,
so not sure why you are muxing these to GPIO pins.
Also, this patch is a bit busy, might be easier to review if you split it
into one for AM335x and one for AM437x changes.
