2023-08-12arm64: dts: imx8mq-librem5-devkit: Drop power-supplyGuido Günther
It's not a valid binding. Instead move the sdio_rst line to the power sequence and use w_disable1 as the vmmc-supply bringing it more in line with other SDIO M2 cards. Resolves following warning: arch/arm64/boot/dts/freescale/imx8mq-librem5-devkit.dtb: mmc@30b50000: Unevaluated properties are not allowed ('power-supply' was unexpected) from schema $id: http://devicetree.org/schemas/mmc/fsl-imx-esdhc.yaml# Reported-by: David Heidelberg <david@ixit.cz> Signed-off-by: Guido Günther <agx@sigxcpu.org> Signed-off-by: Shawn Guo <shawnguo@kernel.org>

2021-01-10arm64: dts: imx8mq-librem5-devkit: Tweak pmic regulatorsGuido Günther
BUCK3 needs a regulator-enable-ramp-delay since otherwise the board freezes on etnaviv probe. With this pgc_gpu suspends and resumes as expected. This must have been always broken since gpcv2 support was enabled. We also enable all the regulators needed for Deep Sleep Mode (DSM) as always-on: - VDD_SOC supplied by BUCK1 - VDDA_1P8 supplied by BUCK7 - VDDA_0P9 supplied by LDO4 - VDDA_DRAM supplied by LDO3 - NVCC_DRAM supplied by BUCK8 - VDD_DRAM supplied by BUCK5 Finally LDO5 and LDO6 provide VDD_PHY_1V8 and VDD_PHY_0V9 used by the SOCs MIPI, HDMI and USB IP cores. While we would in theory be able to turn these off (and I've tested that or LDO6 and mipi with USB disabled) it is of little practical use atm since USB doesn't runtime suspend so let's revisit this at a later point.

GPIO_ACTIVE_x flags are not correct in the context of interrupt flags. These are simple defines so they could be used in DTS but they will not have the same meaning: 1. GPIO_ACTIVE_HIGH = 0 = IRQ_TYPE_NONE 2. GPIO_ACTIVE_LOW = 1 = IRQ_TYPE_EDGE_RISING Correct the interrupt flags, assuming the author of the code wanted same logical behavior behind the name "ACTIVE_xxx", this is: ACTIVE_LOW => IRQ_TYPE_LEVEL_LOW Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org> Acked-By: Tim Harvey <tharvey@gateworks.com> Signed-off-by: Shawn Guo <shawnguo@kernel.org>

The IMU chip on the librem5-devkit is not mounted at the "natural" place that would match normal phone orientation (see the documentation for the details about what that is). Since the lsm9ds1 driver supports providing a mount matrix, we can describe the orientation on the board in the dts: Create a right-handed coordinate system (x * -1; see the datasheet for the axis) and rotate 180 degrees around the y axis because the device sits on the back side from the display.
