[PATCH v2 1/3] dt-bindings: net: ti,cc1352p7: Add bootloader-backdoor-gpios

From: Ayush Singh
Date: Wed Jul 31 2024 - 14:54:01 EST


bootloader-backdoor-gpio (along with reset-gpio) is used to enable
bootloader backdoor for flashing new firmware.

The pin and pin level to enable bootloader backdoor is configured using
the following CCFG variables in cc1352p7:
- SET_CCFG_BL_CONFIG_BL_PIN_NO
- SET_CCFG_BL_CONFIG_BL_LEVEL
