Subject: [U-Boot] [PATCH 2/2] sun50i: a64: A64-Teres-I board detect builtin keyboard
Date: Sun, 18 Aug 2019 17:16:07 +0200	[thread overview]
Message-ID: <20190818151607.9711-2-dr@jones.dk> (raw)
In-Reply-To: <20190818151607.9711-1-dr@jones.dk>

A64-Teres-I board is a laptop which comes with a builtin keyboard.
The keyboard+trackpad controller pauses for 2 seconds at a firmware
prompt before loading its HID interface.

U-Boot needs to wait equally long to reliably enable the keyboard.
