Subject: [PATCH v2 1/2] dt-bindings: nfc: nxp-nci: document pvdd-supply
Date: Fri, 09 Jun 2023 15:42:04 +0000 [thread overview]
Message-ID: <20230609154139.3566-1-raymondhackley@protonmail.com> (raw)
In-Reply-To: <20230609154033.3511-1-raymondhackley@protonmail.com>
PN547/553, QN310/330 chips on some devices require a pad supply voltage
(PVDD). Otherwise, the NFC won't power up.
Document support for pad supply voltage pvdd-supply that is enabled by
the nxp-nci driver so that the regulator gets enabled when needed.
