From: Stephen Boyd Date: Tue, 3 May 2022 19:39:36 +0000 (-0700) Subject: dt-bindings: iio: sx9324: Add CS idle/sleep mode X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=f24333103e844d479161f8d58d59afa2ceac729b;p=linux.git dt-bindings: iio: sx9324: Add CS idle/sleep mode We need to configure the sleep and idle mode of the CS pins for this device. Add a DT property to do this so pins are in a proper state during sleep (either hi-z, grounded, or pulled up to vdd).
