Subject: [PATCH 2/2] gpio: of: Check for "spi-cs-high" in child instead of parent node
Date: Mon, 25 Mar 2019 23:32:09 -0700 [thread overview]
Message-ID: <20190326063209.6421-2-andrew.smirnov@gmail.com> (raw)
In-Reply-To: <20190326063209.6421-1-andrew.smirnov@gmail.com>
"spi-cs-high" is going to be specified in child node of an SPI
controller's representing attached SPI device, so change the code to
look for it there, instead of checking parent node.
