Subject: [PATCH AUTOSEL 4.19 148/252] ARM: dts: at91: sama5d3: fix maximum peripheral clock rates
Date: Fri, 14 Feb 2020 11:10:03 -0500 [thread overview]
Message-ID: <20200214161147.15842-148-sashal@kernel.org> (raw)
In-Reply-To: <20200214161147.15842-1-sashal@kernel.org>
From: Alexandre Belloni <alexandre.belloni@bootlin.com>
[ Upstream commit ee0aa926ddb0bd8ba59e33e3803b3b5804e3f5da ]
Currently the maximum rate for peripheral clock is calculated based on a
typical 133MHz MCK. The maximum frequency is defined in the datasheet as a
ratio to MCK. Some sama5d3 platforms are using a 166MHz MCK. Update the
device trees to match the maximum rate based on 166MHz.
Reported-by: Karl Rudbæk Olsen <karl@micro-technic.com>
