| * | hatch_fp/board_rw: Set DIVIDER_HIGHSIDE to 1 during board init | Patryk Duda | 2021-07-26 | 1 | -1/+5 |
| | | | | | | | | | | | | | | | | | | | | | | On dragonclaw, setting GPIO_DIVIDER_HIGHSIDE to 1 is necessary to enable communication with FP sensor. Until now it was enabled during fp_sensor_init() which was called from fp_task() only in private build (when HAVE_FP_PRIVATE_DRIVER is defined). This was causing problems with fpsensor_hw hardware unittest, which is public build. The problem was solved by enabling GPIO_DIVIDER_HIGHSIDE in configure_fp_sensor_spi(). This approach also required to change get_fp_sensor_type() function to leave GPIO pin enabled.

| * | bloonchipper: Refactor GPIOs to keep RO minimal | Tom Hughes | 2021-02-12 | 1 | -0/+34 |
| We want the amount of code and number of things defined in RO to be as minimal as possible since RO is frozen forever. By keeping RO minimal, we can reduce surface area for attacks and also confusion when GPIOs are removed or renamed. The fingerprint-related code only runs in RW, so move all fingerprint-related GPIOs and associated code into separate files that are only included in RW.
