-Subject: [PATCH] ARM: dts: BCM5301X: Add DT for Meraki MR26
-
-Meraki MR26 is an EOL wireless access point featuring a
-PoE ethernet port and two dual-band 3x3 MIMO 802.11n
-radios and 1x1 dual-band WIFI dedicated to scanning.
-
-Thank you Amir for the unit and PSU.
-
-Hardware info:
-SOC : Broadcom BCM53015A1KFEBG (dual-core Cortex-A9 CPU at 800 MHz)
-RAM : SK Hynix Inc. H5TQ1G63EFR, 1 GBit DDR3 SDRAM = 128 MiB
-NAND : Spansion S34ML01G100TF100, 1 GBit SLC NAND Flash = 128 MiB
-ETH : 1 GBit Ethernet Port - PoE (TPS23754 PoE Interface)
-WIFI0 : Broadcom BCM43431KMLG, BCM43431 802.11 abgn (3x3:3)
-WIFI1 : Broadcom BCM43431KMLG, BCM43431 802.11 abgn (3x3:3)
-WIFI2 : Broadcom BCM43428 "Air Marshal" 802.11 abgn (1x1:1)
-BUTTON: One reset key behind a small hole next to the Ethernet Port
-LEDS : One amber (fault), one white (indicator) LED, separate RGB-LED
-MISC : Atmel AT24C64 8KiB EEPROM i2c
- : Ti INA219 26V, 12-bit, i2c output current/voltage/power monitor
-
-SERIAL:
- WARNING: The serial port needs a TTL/RS-232 3V3 level converter!
- The Serial setting is 115200-8-N-1. The board has a populated
- right angle 1x4 0.1" pinheader.
- The pinout is: VCC (next to J3, has the pin 1 indicator), RX, TX, GND.
-
-Odd stuff:
-
-- uboot does not support lzma compression, but gzip'd uImage/DTB work.
-- uboot claims to support FIT, but fails to pass the DTB to the kernel.
- Appending the dtb after the kernel image works.
-- RGB-controller is supported through an external userspace program.
-- The ubi partition contains a "board-config" volume. It stores the
- MAC Address (0x66 in binary) and Serial No. (0x7c alpha-numerical).
-- SoC's temperature sensor always reports that it is on fire.
- This causes the system to immediately shutdown! Looking at reported
- "418 degree Celsius" suggests that this sensor is not working.
-
-WIFI:
-b43 is able to initialize all three WIFIs @ 802.11bg.
