Subject: [PATCH 5/5] arm64: dts: k3-j721e-proc-board: Add wait time for sampling Type-C DIR line
Date: Wed, 8 Jan 2020 13:18:30 +0200 [thread overview]
Message-ID: <20200108111830.8482-6-rogerq@ti.com> (raw)
In-Reply-To: <20200108111830.8482-1-rogerq@ti.com>
The Type-C compainon chip on the board needs ~133ms (tCCB_DEFAULT)
to debounce the CC lines in order to detect attach and plug orientation
and reflect the correct DIR status. [1]
Let's wait for 300ms before sampling the Type-C DIR line.
