From cd1fb46e02de3c70d6379b00c0e860ca44954574 Mon Sep 17 00:00:00 2001 From: Claudiu Beznea Date: Fri, 2 Feb 2024 10:41:32 +0200 Subject: [PATCH] net: ravb: Move DBAT configuration to the driver's ndo_open API DBAT setup was done in the driver's probe API. As some IP variants switch to reset mode (and thus registers content is lost) when setting clocks (due to module standby functionality) to be able to implement runtime PM move the DBAT configuration in the driver's ndo_open API. This commit prepares the code for the addition of runtime PM.
