ath79: GL-AR750S: Add I2C Support
The GL-AR750S has an internal header for I2C.
Provide DTS definitions for the i2c-gpio driver.
The I2C drivers; kmod-i2c-core, kmod-i2c-gpio
consume ~20 kB of flash and can be loaded as modules,
Default clock measured ~11.2 ms period, ~89 kHz
The board has well-labeled (unpopulated) headers for serial and I2C
along the front edge of the board (the edge with the LEDs). Looking
from the top, rear of the unit (behind Ethernet jacks)
