   4 Subject: [PATCH] ARM: dts: BCM5301X: Add DT for Meraki MR26
   5
   6 Meraki MR26 is an EOL wireless access point featuring a
   7 PoE ethernet port and two dual-band 3x3 MIMO 802.11n
   8 radios and 1x1 dual-band WIFI dedicated to scanning.

  10 Thank you Amir for the unit and PSU.

  12 Hardware info:
  13 SOC   : Broadcom BCM53015A1KFEBG (dual-core Cortex-A9 CPU at 800 MHz)
  14 RAM   : SK Hynix Inc. H5TQ1G63EFR, 1 GBit DDR3 SDRAM = 128 MiB
  15 NAND  : Spansion S34ML01G100TF100, 1 GBit SLC NAND Flash = 128 MiB
  16 ETH   : 1 GBit Ethernet Port - PoE (TPS23754 PoE Interface)
  17 WIFI0 : Broadcom BCM43431KMLG, BCM43431 802.11 abgn (3x3:3)
  18 WIFI1 : Broadcom BCM43431KMLG, BCM43431 802.11 abgn (3x3:3)
  19 WIFI2 : Broadcom BCM43428 "Air Marshal" 802.11 abgn (1x1:1)
  20 BUTTON: One reset key behind a small hole next to the Ethernet Port
  21 LEDS  : One amber (fault), one white (indicator) LED, separate RGB-LED
  22 MISC  : Atmel AT24C64 8KiB EEPROM i2c
  23       : Ti INA219 26V, 12-bit, i2c output current/voltage/power monitor
  24
  25 SERIAL:
  26       WARNING: The serial port needs a TTL/RS-232 3V3 level converter!
  27       The Serial setting is 115200-8-N-1. The board has a populated
  28       right angle 1x4 0.1" pinheader.
  29       The pinout is: VCC (next to J3, has the pin 1 indicator), RX, TX, GND.
  30
  31 Odd stuff:
  32
  33 - uboot does not support lzma compression, but gzip'd uImage/DTB work.
  34 - uboot claims to support FIT, but fails to pass the DTB to the kernel.
  35   Appending the dtb after the kernel image works.
  36 - RGB-controller is supported through an external userspace program.
  37 - The ubi partition contains a "board-config" volume. It stores the
  38   MAC Address (0x66 in binary) and Serial No. (0x7c alpha-numerical).
  39 - SoC's temperature sensor always reports that it is on fire.
  40   This causes the system to immediately shutdown! Looking at reported
  41   "418 degree Celsius" suggests that this sensor is not working.
  42
  43 WIFI:
  44 b43 is able to initialize all three WIFIs @ 802.11bg.
