From 59f96cf6ba88c64278c35d11957a36faaca33de7 Mon Sep 17 00:00:00 2001 From: Frieder Schrempf Date: Tue, 1 Dec 2020 12:39:09 +0100 Subject: NFC: nxp-nci: Make firmware GPIO pin optional There are other NXP NCI compatible NFC controllers such as the PN7150 that use an integrated firmware and therefore do not have a GPIO to select firmware downloading mode. To support this kind of controller, let's make the firmware GPIO optional.
