2018-09-26ARM: dts: meson8b: odroidc1: add stdout-path propertyMartin Blumenstingl1-0/+4
To use the "earlycon" kernel command line parameter (without arguments) we need a stdout-path property under the /chosen node. Add this to make it easier to spot errors early in the boot process when looking for them.

2018-09-26ARM: dts: meson8b: odroidc1: enable the SAR ADCMartin Blumenstingl1-0/+5
Odroid-C1 exposes ADC channels 0 and 1 on the GPIO headers. NOTE: Due to the SoC design these are limited to 1.8V (instead of 3.3V like all other pins). Enable the SAR ADC to enable voltage measurements on these pins. Signed-off-by: Martin Blumenstingl <martin.blumenstingl@googlemail.com> Signed-off-by: Kevin Hilman <khilman@baylibre.com>
2018-09-26ARM: dts: meson8b: odroidc1: add the fixed voltage regulatorsMartin Blumenstingl1-0/+73
There are multiple fixed regulators on the Odroid-C1 board. Add them so they can be used when we add the devices that need them (SAR ADC needs the 1.8V IOREF, RTC needs VDD_RTC). These are: - P5V0 is the main 5V power input - VCC3V3 / VDDIO_AO3V3 / VDD3V3: fixed regulator with 3.3V output which is supplied by P5V0 - IOREF_1V8 / VCC1V8 / VDD1V8: fixed regulator with 1.8V output which is supplied by P5V0 - VDD_RTC: fixed voltage regulator with 0.9V output which is supplied by VDDIO_AO3V3 - DDR_VDDC / DDR3_1V5: fixed voltage regulator with 1.5V output which is supplied by P5V0 - the existing TF_IO and RFLASH_VDD_EN regulators are supplied by VDDIO_AO3V3 - the existing VCCK regulator is supplied by P5V0 This does not add the missing VDDEE regulator (controlled by PWM_D) because it's not clear yet how to configure the voltage of that regulator.

2018-09-26ARM: dts: meson8b: odroidc1: add the CPU voltage regulatorMartin Blumenstingl1-0/+27
The CPU voltage regulator is a "Monolithic Power Systems MP2161" (according to the Odroid-C1+'s schematics). It is driven by PWM_C on GPIODV_9. Hardkernel's 3.10 kernel (based on the Amlogic GPL kernel sources) defines a PWM voltage table with the following values: - 0.86 volts = PWM register value 0x10f001b - (more values in 0.1 volt increments) - 1.14 volts = PWM register value 0x000012a When using the XTAL (24MHz) as input this translates into a PWM period of 12218ns with 0.86V using a duty cycle of 91% and 1.14V using a duty cycle of 0%.

2018-05-09ARM: dts: meson8b: odroid-c1: enable the IR receiverMartin Blumenstingl1-0/+6
The Odroid-C1 comes with an IR receiver. It is connected to the GPIOAO_7 pin and thus using the SoC's internal IR decoder. Signed-off-by: Martin Blumenstingl <martin.blumenstingl@googlemail.com> Signed-off-by: Kevin Hilman <khilman@baylibre.com>

2018-03-20ARM: dts: meson8b-odroidc1: add microSD supportLinus Lüssing1-0/+58
The Odroid C1 features a microSD slot. This patch adds the necessary DT bindings to support it. Signed-off-by: Linus Lüssing <linus.luessing@c0d3.blue> Signed-off-by: Kevin Hilman <khilman@baylibre.com>
2018-02-12ARM: dts: meson8b-odroidc1: ethernet supportEmiliano Ingrassia1-0/+30
The Odroid-C1+ board is equipped with an RTL8211F ethernet PHY which supports 10/100/1000 Mbps ethernet. The PHY reset and interrupt lines are controlled by the SoC via two GPIO lines (GPIOH_4 and GPIOH_3 respectively). The PHY energy efficient ethernet (eee) mode is marked as broken using "eee-broken-1000t" because, during tests, high packet losses were experienced without it.
