[PATCH V2 5/6] clk: imx8mn: Improve ARM PLL table to support CPU frequency scaling
From: Anson Huang
Date: Sat Aug 17 2019 - 18:47:11 EST
i.MX8MN supports CPU running at 1.5GHz/1.4GHz/1.2GHz, add missing
frequency for ARM PLL table, also add .rate_count assignment which
is necessary for searching required PLL rate from the table.
