[PATCH RFT net-next 03/10] soc: sunxi: sram: add entry for a523
From: Chen-Yu Tsai
Date: Tue Jul 01 2025 - 13:12:39 EST
From: Chen-Yu Tsai <wens@xxxxxxxx>
The A523 has two Ethernet controllers. So in the system controller
address space, there are two registers for Ethernet clock delays,
one for each controller.
Add a new entry for the A523 system controller that allows access to
the second register.
