From 80874d8c9e9cbfa195572dfea46f2314098b3869 Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Mon, 26 May 2014 14:05:25 +0200 Subject: [PATCH] spi: core: Ignore unsupported spi-[tr]x-bus-width property values Rejecting unsupported values of spi-tx-bus-width and spi-rx-bus-width may break compatibility with future DTs. Just ignore them, falling back to Single SPI Transfers.
