From a079ff858cc0831f5bbad205016bfd88bf992bb1 Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Fri, 6 Mar 2020 09:50:37 +0100 Subject: spi: dt-bindings: spi-controller: Fix #address-cells for slave mode Currently, the DT bindings for an SPI controller specify that "#address-cells" must be fixed to one. However, that applies to an SPI controller in master mode only. When running in SPI slave mode, "#address-cells" should not be specified. Fix this making "#address-cells" mutually-exclusive with "spi-slave".
