Fabio Estevam e40d0706bf ARM: dts: imx6qdl-tqma6: Fix the SPI chipselect polarity ... The conversion of the spi-imx driver to use GPIO descriptors in commit 8cdcd8aeee ("spi: imx/fsl-lpspi: Convert to GPIO descriptors") helped to detect the following SPI chipselect polarity mismatch on an imx6q-sabresd for example: [ 4.854337] m25p80@0 enforce active low on chipselect handle Prior to the above commit, the chipselect polarity passed via cs-gpios property was ignored and considered active-low. The reason for such mismatch is clearly explained in the comments inside drivers/gpio/gpiolib-of.c: * SPI children have active low chip selects * by default. This can be specified negatively * by just omitting "spi-cs-high" in the * device node, or actively by tagging on * GPIO_ACTIVE_LOW as flag in the device * tree. If the line is simultaneously * tagged as active low in the device tree * and has the "spi-cs-high" set, we get a * conflict and the "spi-cs-high" flag will * take precedence. To properly represent the SPI chipselect polarity, change it to active-low when the "spi-cs-high" property is absent.
