[PATCH 5/5] arm64: dts: k3-j721e-proc-board: Add wait time for sampling Type-C DIR line
From: Roger Quadros
Date: Wed Jan 08 2020 - 06:19:05 EST
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.
