* ARM: dts: exynos: Use interrupt for BCM4330 host wakeup in I9100Paul Cercueil2021-11-151-1/+4
| | | | | | | | | | Switch away from using the deprecated 'host-wakeup-gpios' property, and use a 'host-wakeup' interrupt instead, as suggested by the binding documentation.

* ARM: dts: exynos: Fix BCM4330 Bluetooth reset polarity in I9100Paul Cercueil2021-11-151-1/+1
| | | | | | | | | | | | The reset GPIO was marked active-high, which is against what's specified in the documentation. Mark the reset GPIO as active-low. With this change, Bluetooth can now be used on the i9100.

* ARM: dts: exynos: Disable unused camera input for I9100Timon Baetz2021-05-311-2/+4
| | | | | | | | | | As the back camera is not implemented disable the second pair of fimc child nodes as they are not functional. This prevents creating the associated /dev/videoX devices.

* ARM: dts: exynos: correct fuel gauge interrupt trigger level on GT-I9100Krzysztof Kozlowski2021-03-071-1/+1
| | | | | | | | | | The Maxim fuel gauge datasheets describe the interrupt line as active low with a requirement of acknowledge from the CPU. The falling edge interrupt will mostly work but it's not correct.

* ARM: dts: exynos: adjust node names to DT spec in Exynos4210 boardsKrzysztof Kozlowski2020-10-281-3/+3
| | | | | | | | | | | The Devicetree specification expects device node names to have a generic name, representing the class of a device.

* ARM: dts: exynos: Override thermal by label in Galaxy I9000Krzysztof Kozlowski2020-09-021-15/+13
| | | | | | | | | | | | | Using full paths to extend or override a device tree node is error prone since if there was a typo error, a new node will be created instead of extending the node as it was desired. This will lead to run-time errors that could be hard to detect. A mistyped label on the other hand, will cause a dtc compile error (during build time).

* ARM: dts: exynos: Correct S3C RTC bindings and enable it in Galaxy I9100Krzysztof Kozlowski2020-09-021-0/+18
| | | | | | | | | | | | | | | | | The S3C RTC requires 32768 Hz clock as input which is provided by PMIC (Maxim MAX8997). However there is no clock provided for the PMIC and the driver registers the clock as regulator. This is an old driver which will not be updated so add a workaround: 1. Enable the "clock" regulator in PMIC, 2. Add a fixed-clock to fill missing clock phandle reference in S3C RTC. This allows to enable the S3C RTC and fixes dtbs_check warnings: arch/arm/boot/dts/exynos4210-i9100.dt.yaml: rtc@10070000: clocks: [[5, 346]] is too short arch/arm/boot/dts/exynos4210-i9100.dt.yaml: rtc@10070000: clock-names: ['rtc'] is too short Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org> Link: https://lore.kernel.org/r/20200830135200.24304-3-krzk@kernel.org

* ARM: dts: exynos: Silence i2c-gpio dtschema warning in Galaxy I9100Krzysztof Kozlowski2020-09-021-1/+1
| | | | | | | | | | | | | | | The name of I2C controller over GPIO lines node ends with '-gpio' which confuses dtschema: /arch/arm/boot/dts/exynos4210-i9100.dt.yaml: /: i2c-gpio: {'compatible': ['i2c-gpio'], ... 'maxim,over-volt': [[4500]]}} is not of type 'array' From schema: lib/python3.6/site-packages/dtschema/schemas/gpio/gpio-consumer.yaml Add a '-0' suffix to silence it. This pattern on naming i2c-gpio is already present in many other dts. No functional change.
