From 054320b25520ff3c2440f5d56233c8f672293b3c Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Mon, 7 Jan 2019 16:51:54 +0100 Subject: spi: clps711x: Convert to use CS GPIO descriptors This converts the CLPS711x SPI master driver to use GPIO descriptors for chip select handling. The CLPS711x driver was merely requesting the GPIO and setting the CS line non-asserted so this was a pretty straight-forward conversion. The setup callback goes away.
