Subject: [PATCH 2/4] arm64: dts: qcom: sdm632-fairphone-fp3: Wire up PMI632 LCDB
Date: Fri, 13 Nov 2026 09:16:36 +0100	[thread overview]
Message-ID: <20261113-lcdb-enablement-v1-2-1dc40b49ed82@fairphone.com> (raw)
In-Reply-To: <20261113-lcdb-enablement-v1-0-1dc40b49ed82@fairphone.com>

Since Linux has gained LCDB support now, wire up the LCDB regulators so
we can turn them off and on as desired.
