[PATCH v2 3/8] dt-bindings: nfc: nxp,pn532: convert to dtschema
From: Krzysztof Kozlowski <hidden>
Date: 2021-10-11 07:40:02
Also in:
linux-devicetree, lkml, netdev, oe-linux-nfc
Subsystem:
networking drivers, nfc subsystem, open firmware and flattened device tree bindings, the rest · Maintainers:

Convert the NXP PN532 NFC controller to DT schema format. Drop the "clock-frequency" property during conversion because it is a property of I2C bus controller, not I2C slave device. It was also never used by the driver.
