ARM: dts: meson8b: Add support for the Endless Mini (EC-100)
The Endless Mini (EC-100) is a grapefruit-sized computer based on the Amlogic Meson8b (S805) SoC which comes in two variants. Both variants have in common: - Amlogic Meson8b (S805) SoC - two USB 2.0 ports on the rear, one one the front (connected to the SoC through an internal hub) - 3.5mm Stereo out and MIC combo port - HDMI and CVBS output - 5V power supply (rated at 3A / 15W) - an internal embedded micro-controller (called "EC") which implements a "breathing" effect for the LED and allows shutting down (powering off) the whole device - 10/100 Mbit/s Ethernet using an IC Plus IP101A/G PHY (note: the website incorrectly lists a Gigabit Ethernet port) - the CPU voltage is regulated using a PWM regulator. The GPL sources of the EC-100 are using a PWM value of 0x1c0000 for 0.86V and a PWM value of 0x00001c for 1.14V. When using the XTAL (24MHz) as input this translates into a PWM period of 1148ns with 0.86V using a duty cycle of 100% and 1.14V using a duty cycle of 0%. The main differences are: - the main indicator for the variant is the RAM size: the "cheaper" variant has 1 GB of RAM, while the more expensive one comes with 2GB - the storage size differs: 24 GB vs 32 GB - the "1 GB RAM" variant has Ethernet connectivity only, while the "2 GB" variant has a Realtek RTL8723BS SDIO chip which adds 802.11b/g/n wifi and Bluetooth 4.0 support Signed-off-by: Martin Blumenstingl <martin.blumenstingl@googlemail.com> Signed-off-by: Kevin Hilman <khilman@baylibre.com>
