Hi Marek,
> Odroid HC1 board is based on Odroid XU4 board, but it has no HDMI,
> no eMMC, no build-in USB3.0 hub, no extension port pins, and no GPIO
> button. USB3.0 ports are used for build-in JMicron USB to SATA bridge
> and Gigabit R8152 ethernet chips. HC1 uses only passive cooling.
>
> This patch also updates Odroid's ADCmax array and reduces ADC
> tolerance to 1% to ensure that XU4 and HC1 revisions are properly
> detected.
>
> I've tested this with XU3, XU3-lite, XU4 and HC1 boards. In case of
> my test boards I got following values from ADC register: 372, 370,
> 1281 and 1313.
