From: Esben Haabendal <eha@deif.com> This patch series fixes two race conditions and minor issues with tracking the stopped state when something goes wrong. With that in place, DMA support works with NXP LS1021A, so it is enabled in the last patch. Changes in v2: * Fixed speling mistake in commit message * Rebased to v4.18-rc4 Esben Haabendal (4): i2c: imx: Fix reinit_completion() use i2c: imx: Fix race condition in dma read i2c: imx: Simplify stopped state tracking arm: dts: ls1021a: Enable I2C DMA support arch/arm/boot/dts/ls1021a.dtsi | 6 ++++++ drivers/i2c/busses/i2c-imx.c | 23 ++++++++++++----------- 2 files changed, 18 insertions(+), 11 deletions(-)
