└─>LED support for LGM SoC series
In linux kernel since version 5.2 (release Date: 2019-07-07)  
This option enables support for LEDs connected to GPIO lines on
Lightning Mountain (LGM) SoC. Lightning Mountain is a AnyWAN
gateway-on-a-chip SoC to be shipped on mid and high end home
gateways and routers.

These LEDs are driven by a Serial Shift Output (SSO) controller.
The driver supports hardware blinking and the LEDs can be configured
to be triggered by software/CPU or by hardware.

Say 'Y' here if you are working on LGM SoC based platform. Otherwise,
say 'N'. To compile this driver as a module, choose M here: the module
will be called leds-lgm-sso.
