Subject: [PATCH net-next v3 0/2] nfc: s3fwrn5: Add optional pvdd-supply
Date: Thu, 12 Nov 2026 19:25:48 +0200 [thread overview]
Message-ID: <20261112-m52xq-nfc-netdev-v3-0-725a61ce4148@gmail.com> (raw)
The Samsung S3FWRN5 NFC chip has a PVDD supply pin. On the Samsung
Galaxy M52 5G (sm7325) it is fed by a PMIC regulator that is not
always-on, so the driver has to enable it. These two patches add the
optional supply to the binding and make the driver enable it before the
enable GPIO is driven.
They were part of the series "arm64: dts: qcom: Add Samsung Galaxy M52
5G" (v2). As suggested by Krzysztof, they are split out and resent for
net-next. The DTS patches stay in the Qualcomm series; the DTS node uses
pvdd-supply only after this binding is merged.
Changes since v2 (as part of the DTS series):
- sent as a separate series with the net-next prefix
- no code changes, Reviewed-by from Krzysztof kept
