From mboxrd@z Thu Jan 1 00:00:00 1970 Content-Type: multipart/mixed; boundary="===============4523284250159401170==" MIME-Version: 1.0 From: Krzysztof Kozlowski To: linux-nfc@lists.01.org Subject: [PATCH 3/7] dt-bindings: nfc: st, st21nfca: convert to dtschema Date: Sun, 10 Oct 2021 16:23:13 +0200 Message-ID: <20211010142317.168259-3-krzysztof.kozlowski@canonical.com> In-Reply-To: <20211010142317.168259-1-krzysztof.kozlowski@canonical.com> List-Id: --===============4523284250159401170== Content-Type: text/plain; charset="utf-8" MIME-Version: 1.0 Content-Transfer-Encoding: quoted-printable Convert the ST ST21NFCA NFC controller to DT schema format. The conversion also adds a new required property - interrupts - because it was missing in the old bindings by mistake.
