I was using the name `boot-gpios` since cc1352-flasher uses the name boot-line. Anyway, would `bsl-gpios` be better? Or for more descriptive names, I guess it can be `bootloader-config-gpios` or `bootloader-backdoor-gpios`. Ayush Singh

This is the most descriptive and therefore, IMO, best.

boot-gpio (along with reset-gpio) is used to enable bootloader backdoor for flashing new firmware. The pin and pin level to enabel bootloader backdoor is configed 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 <ayush@beagleboard.org> --- Documentation/devicetree/bindings/net/ti,cc1352p7.yaml | 4 ++++ 1 file changed, 4 insertions(+)
