* write protect: extract checking write protectDawid Niedzwiecki2022-02-111-5/+3
| | | | | | | | | | | | | | | | | | | | | | The write-protect state can be checked on 2 pins GPIO_WP or GPIO_WP_L. The CONFIG_WP_ACTIVE_HIGH config is used to distinguish these two cases. Move the checking the config and pin state to a separate header file. For Zephyr, start using the gpio_get_level function that takes into account the GPIO_ACTIVE_LOW flag. Also, use 'gpio-wp' alias to the WP pin instead of the legacy enum-name property and 'int-wp' alias to the WP GPIO interrupt.

* cbi: Add CONFIG_EEPROM_CBI_WPAseda Aboagye2021-07-291-0/+9
| | | | | | | | | | | | | | | | | | | | | This commit adds the config option, CONFIG_EEPROM_CBI_WP. It is to be defined when the EC directly controls the CBI EEPROM WP signal. The EC will set the WP according to the result of `system_is_locked()`. Note that once the WP is set, the EC must be reset via EC_RST_ODL in order for the WP to become unset. This is enabled by the accompanying hardware.
