-Subject: [PATCH 086/146] clk: sunxi-ng: Use u64 for calculation of NM rate
-
-Allwinner H6 SoC has multiplier N range between 1 and 254. Since parent
-rate is 24MHz, intermediate result when calculating final rate easily
-overflows 32 bit variable.
-
-Because of that, introduce function for calculating clock rate which
-uses 64 bit variable for intermediate result.
-
-Fixes: 6174a1e24b0d ("clk: sunxi-ng: Add N-M-factor clock support")
-Fixes: ee28648cb2b4 ("clk: sunxi-ng: Remove the use of rational computations")
-
-CC: <stable@vger.kernel.org>
-Signed-off-by: Jernej Skrabec <jernej.skrabec@siol.net>
