From d87daa18535d38385f1da460c557c004e0b66347 Mon Sep 17 00:00:00 2001 From: Claudiu Beznea Date: Mon, 26 Aug 2024 20:31:14 +0300 Subject: [PATCH 1/5] dt-bindings: clk: at91: Add clock IDs for the slow clock controller Add clock IDs for the slow clock controller. Previously, raw numbers were used (0 or 1) for clocks generated by the slow clock controller. This leads to confusion and wrong IDs were used on few device trees. To avoid this add macros.
