From mboxrd@z Thu Jan 1 00:00:00 1970 Content-Type: multipart/mixed; boundary="===============4851317162857814390==" MIME-Version: 1.0 From: Krzysztof Kozlowski To: linux-nfc@lists.01.org Subject: [PATCH v2 3/8] dt-bindings: nfc: nxp, pn532: convert to dtschema Date: Mon, 11 Oct 2021 09:39:29 +0200 Message-ID: <20211011073934.34340-4-krzysztof.kozlowski@canonical.com> In-Reply-To: <20211011073934.34340-1-krzysztof.kozlowski@canonical.com> List-Id: --===============4851317162857814390== Content-Type: text/plain; charset="utf-8" MIME-Version: 1.0 Content-Transfer-Encoding: quoted-printable 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.
