From 14448e9c97f06717cac95888329ab7cf31929050 Mon Sep 17 00:00:00 2001 From: Marcel Ziswiler Date: Mon, 31 Jan 2022 23:08:31 +0100 Subject: [PATCH] mmc: fsl_esdhc_imx: fix watermark level in dma Seems that we need the waterlevel setting not only for PIO mode as without this at least the i.MX 8M Mini won't boot anymore when being written by such a U-Boot. Corruption has also been observed both on the i.MX 6 as well as i.MX 8M Mini when using ums on the eMMC. Fix this by setting the watermark level again regardless of whether in DMA or PIO mode.
