2023-06-21ARM: dts: Move .dts files to vendor sub-directoriesRob Herring1-923/+0
The arm dts directory has grown to 1559 boards which makes it a bit unwieldy to maintain and use. Past attempts stalled out due to plans to move .dts files out of the kernel tree. Doing that is no longer planned (any time soon at least), so let's go ahead and group .dts files by vendors. This move aligns arm with arm64 .dts file structure. There's no change to dtbs_install as the flat structure is maintained on install. The naming of vendor directories is roughly in this order of preference: - Matching original and current SoC vendor prefix/name (e.g. ti, qcom) - Current vendor prefix/name if still actively sold (SoCs which have been aquired) (e.g. nxp/imx) - Existing platform name for older platforms not sold/maintained by any company (e.g. gemini, nspire) The whole move was scripted with the exception of MAINTAINERS and a few makefile fixups.

2020-08-30ARM: dts: imx: Fix the SPI chipselect polarityFabio Estevam1-1/+1
The conversion of the spi-imx driver to use GPIO descriptors in commit 8cdcd8aeee28 ("spi: imx/fsl-lpspi: Convert to GPIO descriptors") helped to detect the following SPI chipselect polarity mismatch on an imx6q-sabresd: [ 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.

Since commit 4664179fe679 ("ARM: dts: imx7s: Enable SNVS power key according to board design") snvs_pwrkey is disabled by default, so there is no need for disabling it explicitly in the board dts anymore.
