Subject: [PATCH] ARM: dts: vf610-zii-dev-rev-c: fix polarity of at86rf233
 reset line
Message-ID: <Yzc0B6jNsZyQZizj@google.com>
MIME-Version: 1.0
Content-Type: text/plain; charset=us-ascii
Content-Disposition: inline
Precedence: bulk

at86rf230 driver starts with having reset line high, and then drives it
low and then high again, and even calls it "rstn" internally, therefore
it needs to be annotated as "active low" in the DTS.

This will make difference when at86rf230 driver will be converted to
gpiod API that respects declared line polarity.
