If anyone has any objections, please let me know. ------------------ From: Josua Mayer [ Upstream commit 600f01dc4bd0c736b3ffea9f7976136d8bf1b136 ] Currently, the binding requires 'spi-cpha' for SJA1105 and 'spi-cpol' for SJA1110. However, the SJA1110 supports both SPI modes 0 and 2. Mode 2 (cpha=0, cpol=1) is used by the NXP LX2160 Bluebox 3. On the SolidRun i.MX8DXL HummingBoard Telematics, mode 0 is stable, while forcing mode 2 introduces CRC errors especially during bursts. Drop the requirement on spi-cpol for SJA1110.
