add support for the Cisco Meraki MR32.
This is a dual-band enterprise class 802.11ac access point.
The unit was donated by Chris Blake. Thank you!
SoC: Broadcom BCM53016A1 (1 GHz, 2 cores)
RAM: 128 MiB
NAND: 128 MiB Spansion S34ML01G2 (~114 MiB useable)
ETH: 1GBit Ethernet Port - PoE
WIFI1: Broadcom BCM43520 an+ac (2x2:2 - id: 0x4352)
WIFI2: Broadcom BCM43520 bgn (2x2:2 - id: 0x4352)
WIFI3: Broadcom BCM43428 abgn (1x1:1 - id: 43428)
BLE: Broadcom BCM20732 (ttyS1)
LEDS: 1 x Programmable RGB Status LED (driven by a PWM)
1 x White LED (GPIO)
1 x Orange LED Fault Indicator (GPIO)
2 x LAN Activity / Speed LEDs (On the RJ45 Port)
BUTTON: one Reset button
MISC: AT24C64 8KiB EEPROM (i2c - stores Ethernet MAC)
ina219 hardware monitor (i2c)
Kensington Lock
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, RX, TX, GND.
Odd stuff:
- uart0 clock frequency is 62.5 MHz.
- The LEDs are labeled as SYS-LED1 through SYS-LED3
because of the silkscreen on the PCB.
- the original u-boot has been compiled with most functions
and commands disabled. The u-boot env isn't setup properly
either and as a result, the bcm47xxpart probing is not
working. Hence, the nand partitions are specified through a
"fixed-partition" binding.
- The "WICED SMART(TM)" Bluetooth LE 4.0 BCM20732 chip is
connected to uart2 of the SoC. The BCM20732 does not
provide a HCI. So the linux' bluetooth stack is useless.
The mock-up node with the compatible binding and
enable-gpios property is provided solely as documentation.
