Re: [RESEND][PATCH] clk: at91: generated: Truncate divisor to GENERATED_MAX_DIV + 1
From: Stephen Boyd <sboyd@kernel.org>
Date: 2019-07-22 21:32:17
Also in:
linux-clk, lkml
Quoting Codrin Ciubotariu (2019-06-25 02:10:02)
In clk_generated_determine_rate(), if the divisor is greater than
GENERATED_MAX_DIV + 1, then the wrong best_rate will be returned.
If clk_generated_set_rate() will be called later with this wrong
rate, it will return -EINVAL, so the generated clock won't change
its value. Do no let the divisor be greater than GENERATED_MAX_DIV + 1.
