From: Marek Szyprowski Date: Fri, 3 Nov 2017 08:30:30 +0000 (+0100) Subject: ARM: Samsung: Add Exynos5422-based Odroid HC1 support X-Git-Tag: v2018.01-rc2~14^2 X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=7090ead3f2a821c6f043ecbb5f7cecf6ffecdebb;p=oweals%2Fu-boot.git ARM: Samsung: Add Exynos5422-based Odroid HC1 support 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.
