Hi Lukasz,
Subject: [PATCH v3 04/11] clk: Extend struct clk to provide information regarding clock rate
This commit extends the struct clk to provide information regarding the clock rate. As a result the clock tree traversal is performed at most once, and further reads are using the cached value.
I am thinking recalc is needed for some platforms, for clks without CLK_GET_RATE_NOCACHE, It is to use cached value. Since your test mostly on i.MX6Q, so it should be fine for now.
