Date: Mon, 26 May 2014 14:05:25 +0200 From: Geert Uytterhoeven <geert+renesas@...der.be> To: Mark Brown <broonie@...nel.org> Cc: linux-spi@...r.kernel.org, linux-kernel@...r.kernel.org, Geert Uytterhoeven <geert+renesas@...der.be> 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.
