Subject: [PATCH 01/15] clk: rockchip: pll: Fix double use of postdiv1
Date: Thu, 30 Jul 2026 14:12:50 +0000 [thread overview]
Message-ID: <20260730141308.1218014-2-jonas@kwiboo.se> (raw)
In-Reply-To: <20260730141308.1218014-1-jonas@kwiboo.se>
The possible frac_rate part of rk3036_pll plls is divided two times by
postdiv1 instead of both postdiv1 and postdiv2 as the integer part. Fix
this by using postdiv2 in the second do_div() call.
