Subject: [PATCH 0/2] USB: serial: cp210x: provide gpio valid mask
Date: Fri,  9 Apr 2021 17:52:14 +0200	[thread overview]
Message-ID: <20210409155216.31867-1-johan@kernel.org> (raw)

Use the new GPIO valid-mask feature to inform gpiolib which pins are
available for use instead of handling that in a request callback.
    
This also allows user space to figure out which pins are available
through the chardev interface without having to request each pin in
turn.
