Subject: [PATCH V2 5/6] clk: imx8mn: Improve ARM PLL table to support CPU frequency scaling
Date:   Sat, 17 Aug 2019 18:28:19 -0400
Message-Id: <1566080900-2539-5-git-send-email-Anson.Huang@nxp.com>
In-Reply-To: <1566080900-2539-1-git-send-email-Anson.Huang@nxp.com>
References: <1566080900-2539-1-git-send-email-Anson.Huang@nxp.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

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.
