The Allwinner F1C100s series of SoCs shares many peripherals with other Allwinner SoCs. Since they are compatible, we can use the existing drivers, and just need to enable the devices in the DT. This series adds the I2C controllers, the PWM device, the CIR (infrared) device and the LRADC (aka. KEYADC, low res ADC) to the F1C100s .dtsi, so boards can just use them by setting 'status = "okay";'. The only thing missing driver-wise is the IR mod clock, which was not modeled in our CCU driver. Patch 5/9 fixes that. For every device there is one patch that adds the new compatible string to the DT binding, and another patch to add the DT node. This has been tested with a Lctech Pi F1C200s board, by: - Connecting an LED to PE6, and configuring this as the PWM pin in the DT. Doing a sweep on /sys/class/pwm/pwm1/duty_cycle made the LED fade out. - Configuring PD0/PD12 as I2C0, and letting i2c-detect find the on-board NS2009 I2C chip. - Connecting two resistors to the "ADC" pin, and configuring them as two buttons in the DT. /dev/input/event0 properly reported button presses. - Connecting an infrared receiver to PE11, configured as CIR. ir-keytable reported key presses on a remote control. All those (basic) tests were successful, and prove that the peripherals do work and are compatible. Please have a look and test on your hardware, if possible.
