Subject: [PATCH v2] clk: sunxi: fix sun6i PLL1 .recalc_rate() result
Date: Sat, 24 Jan 2015 16:42:39 +0800 [thread overview]
Message-ID: <1422088959-23365-1-git-send-email-wens@csie.org> (raw)
PLL1 on sun6i has its N factor start from 1 (N = register value + 1).
Make the factors clk driver aware of this so clk_factors_recalc_rate()
gives the correct result.

Somehow I remember doing this during the A23 bring-up, but never sent it,
and the patch was lost.
Changes in v2:
Added better commit message.
