Subject: [PATCH 4.4 39/64] pinctrl: amd: use higher precision for 512 RtcClk
Date: Tue, 17 Nov 2020 14:05:02 +0100 [thread overview]
Message-ID: <20201117122108.094251071@linuxfoundation.org> (raw)
In-Reply-To: <20201117122106.144800239@linuxfoundation.org>
From: Coiby Xu <coiby.xu@gmail.com>
commit c64a6a0d4a928c63e5bc3b485552a8903a506c36 upstream.
RTC is 32.768kHz thus 512 RtcClk equals 15625 usec. The documentation
likely has dropped precision and that's why the driver mistakenly took
the slightly deviated value.
