Subject: [U-Boot] [PATCH 2/4] i2c: meson: reduce timeout
Date: Sun, 26 Nov 2017 17:40:55 +0100 [thread overview]
Message-ID: <20171126164057.27728-3-b.galvani@gmail.com> (raw)
In-Reply-To: <20171126164057.27728-1-b.galvani@gmail.com>
The datasheet doesn't specify a suggested timeout and 500ms seems very
long: reduce it to 100ms.
