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 Signed-off-by: Ayush Singh <redacted> --- Documentation/devicetree/bindings/net/ti,cc1352p7.yaml | 7 +++++++ 1 file changed, 7 insertions(+)
