Subject: [PATCH 0/2] clk: meson: MPLL fixes for Meson8b
Date: Sat, 1 Apr 2017 15:02:23 +0200 [thread overview]
Message-ID: <20170401130225.8811-1-martin.blumenstingl@googlemail.com> (raw)
Jerome recently added the MPLL clocks to the Meson8b clock driver: [0]
On my board this unfortunatley causes a division by zero error which
is fixed by patch #1 in this series.
While investigating this I found that there also seems to be a 32bit
overflow in the calculation in rate_from_params(), which is fixed by
patch #2 in this series.
If the review of patch #2 reveals problems then patch #1 should still
be applied.
This series is based to the "clk-meson" branch (e65ae3fb97b4
"dt-bindings: clock: gxbb-clkc: Add GXL compatible variant").
