Subject: [PATCH v2 06/17] clk: imx: pll14xx: use rate_table for audio plls
Date: Fri, 10 May 2024 17:19:01 +0800 [thread overview]
Message-ID: <20240510-imx-clk-v2-6-c998f315d29c@nxp.com> (raw)
In-Reply-To: <20240510-imx-clk-v2-0-c998f315d29c@nxp.com>
From: Shengjiu Wang <shengjiu.wang@nxp.com>
The generated clock frequency may not accurate, for example
the expected rate is 361267200U, but result is 361267199U.
Add rate_table for audio clocks to avoid such issue.
