From: Uwe Kleine-König <u.kleine-koenig@xxxxxxxxxxxxxx> [ Upstream commit ce1dac560a74220f2e53845ec0723b562288aed4 ] While in commit 2dd33f9cec90 ("spi: imx: support DMA for imx35") it was claimed that DMA works on i.MX25, i.MX31 and i.MX35 the respective device trees don't add DMA channels. The Reference manuals of i.MX31 and i.MX25 also don't mention the CSPI core being DMA capable. (I didn't check the others.) Since commit e267a5b3ec59 ("spi: spi-imx: Use dev_err_probe for failed DMA channel requests") this results in an error message spi_imx 43fa4000.spi: error -ENODEV: can't get the TX DMA channel! during boot. However that isn't fatal and the driver gets loaded just fine, just without using DMA.
