Hi,
I wanted to know the part number

What is part number?

for the leds-gpio.c in the driver/leds folder and the device tree bindings for this driver .Can some one point out to me where in Linux kernel it is?

Also why below line has been used.Is it mandatory?
...
.of_match_table = of_gpio_leds_match,

This is needed when you are using device tree for getting the board settings but you can also do the same without this as well. Read up on device tree in kernel Documentation folder.
