From 8ee4ffcd0bf684ade6eccffec796a49ee15b3333 Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Fri, 19 Aug 2022 13:02:53 +0200 Subject: [PATCH] ARM: imx: Update DDR frequency on i.MX8M Plus DHCOM Commit 99c7cc58e12 ("ddr: imx: Add i.MX9 DDR controller driver") contains an inobvious side-effect which renders all systems using DRAM controller at 3732 MT/s unbootable. The change is located in ddrphy_init_set_dfi_clk(), where the switch case statement entry 3732 changed to entry 3733, so any board with DDR calibration data for 3732 MT/s operations needs to be updated to 3733 MT/s to match the change. Since there is currently only one such board, update the board instead of handling both 3732 and 3733 options in the driver. It is likely the NXP MX8MP RPA update will follow and use the later value too.
