From 6212e5bc6979c17da1d54fb0841e99a967101d11 Mon Sep 17 00:00:00 2001 From: Dario Binacchi Date: Mon, 11 Dec 2023 23:05:52 +0100 Subject: [PATCH] ARM: dts: stm32: make the LTDC clock usable by the clock driver As described in [1], the "clocks" property contains "a phandle to the clock device node, an index selecting between gated clocks (0) and other clocks (1), and an index specifying the clock to use." The current version of the clock driver, unlike the kernel, is currently able to properly handle nodes with "clocks" properties with an index set to 0. This patch is preparatory for future developments that require the use of the LTDC clock.
