Subject: [PATCH 0/3] arm64: mx93: etherrnet: set TX_CLK in RMII mode

This series adds support for setting the TX_CLK direction in the eQOS
ethernet core on the i.MX93 when RMII mode is used.

According to AN14149, when the i.MX93 ethernet controller is used in
RMII mode, the TX_CLK *must* be set to output mode. 

Add a devicetree property with the register to set this bit and parse it
in the dwmac-imx driver.
