From 6a11d3a00dc1f152e8cdf97171128c4186695a9d Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Mon, 31 Oct 2022 21:48:38 +0100 Subject: [PATCH] clk: imx: pll14xx: Add 320 MHz and 640 MHz entries for PLL146x The PLL146x is used to implement SYS_PLL3 on i.MX8MP and can be used to drive UARTn_ROOT clock. By setting the PLL3 to 320 MHz or 640 MHz, the PLL3 output can be divided down to supply UARTn_ROOT clock with precise 64 MHz, which divided down further by 16x oversampling factor used by the i.MX UART core yields 4 Mbdps baud base for the UART IP. This is useful e.g. for BCM bluetooth chips, which can operate up to 4 Mbdps. Add 320 MHz and 640 MHz entries so the PLL can be configured accordingly.
