1fcd625c0a ipq40xx: Remove phy reset gpio from Cisco Meraki MR33
There is currently no code to read the phy reset gpios for the ethernet
PHY. It would also have been better to use the more common name
"phy-reset-gpios" for this property.

9ca81646b9 ipq40xx: Use constant to set gpio active low/high
The GPIO configuration in the DTS have as third parameter the active
low/high configuration. This parameter is not easy to parse by humans when
it is only set to 0/1. It is better to use the predefined constants
GPIO_ACTIVE_HIGH and GPIO_ACTIVE_LOW.

4943afd781 ipq40xx: add Cisco Meraki MR33 Support
This patch adds support for Cisco Meraki MR33

hardware highlights:

SOC:	IPQ4029 Quad-Core ARMv7 Processor rev 5 (v7l) Cortex-A7
DRAM:	256 MiB DDR3L-1600 @ 627 MHz Micron MT41K128M16JT-125IT
NAND:	128 MiB SLC NAND Spansion S34ML01G200TFV00 (106 MiB usable)
ETH:	Qualcomm Atheros AR8035 Gigabit PHY (1 x LAN/WAN) + PoE
WLAN1:	QCA9887 (168c:0050) PCIe 1x1:1 802.11abgn ac Dualband VHT80
WLAN2:	Qualcomm Atheros QCA4029 2.4GHz 802.11bgn 2:2x2
WLAN3:	Qualcomm Atheros QCA4029 5GHz 802.11a/n/ac 2:2x2 VHT80
LEDS:	1 x Programmable RGB+White Status LED (driven by Ti LP5562 on i2c-1)
	1 x Orange LED Fault Indicator (shared with LP5562)
	2 x LAN Activity / Speed LEDs (On the RJ45 Port)
BUTTON:	one Reset button
MISC:	Bluetooth LE Ti cc2650 PG2.3 4x4mm - BL_CONFIG at 0x0001FFD8
	AT24C64 8KiB EEPROM
	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
	1x4 0.1" header with half-height/low profile pins.
	The pinout is: VCC (little white arrow), RX, TX, GND.

Flashing needs a serial adaptor, as well as patched ubootwrite utility
(needs Little-Endian support). And a modified u-boot (enabled Ethernet).
Meraki's original u-boot source can be found in:
<https://github.com/riptidewave93/meraki-uboot/tree/mr33-20170427>

Add images to do an installation via bootloader:
 0. open up the MR33 and connect the serial console.

 1. start the 2nd stage bootloader transfer from client pc:

  # ubootwrite.py --write=mr33-uboot.bin
  (The ubootwrite tool will interrupt the boot-process and hence
   it needs to listen for cues. If the connection is bad (due to
   the low-profile pins), the tool can fail multiple times and in
   weird ways. If you are not sure, just use a terminal program
   and see what the device is doing there.

 2. power on the MR33 (with ethernet + serial cables attached)
    Warning: Make sure you do this in a private LAN that has
    no connection to the internet.

 - let it upload the u-boot this can take 250-300 seconds -

 3. use a tftp client (in binary mode!) on your PC to upload the sysupgrade.bin
    (the u-boot is listening on 192.168.1.1)
    # tftp 192.168.1.1
    binary
    put openwrt-ipq40xx-meraki_mr33-squashfs-sysupgrade.bin

 4. wait for it to reboot

 5. connect to your MR33 via ssh on 192.168.1.1

For more detailed instructions, please take a look at the:
"Flashing Instructions for the MR33" PDF. This can be found
on the wiki: <https://openwrt.org/toh/meraki/mr33>
(A link to the mr33-uboot.bin + the modified ubootwrite is
also there)

Thanks to Jerome C. for sending an MR33 to Chris.
