[PATCH v3 1/3] gpio: tps65215: Add TPS65215 to platform_device_id table

Shree Ramamoorthy
2025-01-13T22:56:00Z

Add platform_device_id struct and use the platform_get_device_id() output
to match which PMIC device is in use. With new name options, the gpio_chip
.label field is now assigned to the platform_device name match.

Remove MODULE_ALIAS since it is now generated by MODULE_DEVICE_TABLE.
