Subject: [PATCH v6 3/3] pinctrl: bcm2835: Add support for output-low output-high properties
Date: Sun, 29 Apr 2018 15:28:12 -0400 [thread overview]
Message-ID: <1525030092-3643-3-git-send-email-matheus@castello.eng.br> (raw)
In-Reply-To: <1525030092-3643-1-git-send-email-matheus@castello.eng.br>
Properties to set initial value of pin output buffer.
This can be useful for configure hardware in overlay files, and in early
boot for checking it states in QA sanity tests.
