2021-10-15arm64: dts: imx8mq-librem5: add power sequencing for M.2 cardsAngus Ainslie
Some wifi cards need reset asserted until after the power supplies have been enabled. So wire up the W_DISABLE signal for the SDIO port (WIFI_REG_ON net) and the BT_REG_ON net to use it for power sequencing.

2020-09-22arm64: dts: imx8mq: correct interrupt flagsKrzysztof Kozlowski
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>
2020-09-13arm64: dts: imx8mq-librem5: Add interrupt-names to ti,tps6598xKrzysztof Kozlowski
The ti,tps6598x binding requires interrupt-names property. The driver does not really use it but the hardware could have more interrupt lines connected.

The 'interrupt-names' property is not described in dtschema, not used by the driver and does not really make sense as its value is simple 'irq'. Drop it to fix dtbs_check warnings like: arch/arm64/boot/dts/freescale/imx8mq-librem5-devkit.dt.yaml: pmic@4b: 'interrupt-names' does not match any of the regexes: 'pinctrl-[0-9]+' Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org> Signed-off-by: Shawn Guo <shawnguo@kernel.org>

2020-08-23arm64: dts: Add a device tree for the Librem 5 phoneAngus Ainslie (Purism)
Add a devicetree description for the Librem 5 phone. 4 hardware revisions have been available. Some revisions include changes that need different software to be run. So far, r3 ("Dogwood") is one such example, see: "Aspen" r0 not supported (very few devices exist) "Birch" r1 supported by r2 "Chestnut" r2 added by this patch "Dogwood" r3 added by this patch "Evergreen" r4 tba / most likely supported by r3 See https://puri.sm/products/librem-5/ for more information. This boots to a working console with working WWAN modem, wifi usdhc, IMU sensor device, proximity sensor, haptic motor, gpio keys, GNSS and LEDs.
