Subject: [PATCH 2/2] dt-bindings: i2c: sun6i-p2wi: Fix the binding example
Date: Wed, 3 Jul 2019 11:53:38 +0200 [thread overview]
Message-ID: <20190703095338.11266-2-maxime.ripard@bootlin.com> (raw)
In-Reply-To: <20190703095338.11266-1-maxime.ripard@bootlin.com>
Even though the binding claims that the frequency can go up to 6MHz, the
common i2c binding sets a limit at 3MHz, which then triggers a warning.
Since the only SoC that uses that bus uses a frequency of 100kHz, and that
this bus hasn't been found in an SoC for something like 5 years, let's just
fix the example to have a frequency within the acceptable range for i2c.
