imx: add Aqara Gateway ZHWG11LM support
Aqara ZHWG11LM is a is a wall-mounted zigbee-to-internet gateway. It is almost a twin of Xiaomi DGNWG05LM with another wifi chip. Device specifications: * SoC: Freescale iMX6ULL * RAM: 256MiB * Flash: 256MiB NAND flash * Wireless 2.4GHz (RTL8189ES): b/g/n * Zigbee Chip: NXP jn5169 * Ring of RGB leds * BTN0 button * Sound chip TFA9882 + speaker Flashing instructions: Flashing requires a flashing tool from NXP: https://github.com/NXPmicro/mfgtools * solder wires and attach to system UART and usb connector * stop uboot by pressing any key * enter `bmode usb` to enable flashing over USB * run `mfgtoolcli` on the main computer to write kernel, dtb and rootfs to the device Known issues: - RTL8189ES driver is buggy and may cause freezes and kernel panics - Removing wdev disables the device until reboot. Patch is required. Signed-off-by: Ivan Belokobylskiy <[email protected]>
