From: Felipe Balbi Date: Wed, 11 Sep 2019 06:16:22 +0000 (+0300) Subject: PTP: add support for one-shot output X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=823eb2a3c4c7;p=linux.git PTP: add support for one-shot output Some controllers allow for a one-shot output pulse, in contrast to periodic output. Now that we have extensible versions of our IOCTLs, we can finally make use of the 'flags' field to pass a bit telling driver that if we want one-shot pulse output.
