Subject: [PATCH v4 5/5] ARM: dts: omap4-embt2ws: enable 32K clock on WLAN
Date: Sat, 16 Sep 2023 12:05:15 +0200	[thread overview]
Message-ID: <20230916100515.1650336-6-andreas@kemnade.info> (raw)
In-Reply-To: <20230916100515.1650336-1-andreas@kemnade.info>

WLAN did only work if clock was left enabled by the original system,
so make it fully enable the needed resources itself.
