drivers: stm32_tamp: add tamper events detection support The anti-tamper detection circuit is used to protect sensitive data from external attacks. The backup registers, as well as other secrets in the device, are protected by this anti-tamper detection circuit with some tamper pins and internal tampers. The external tamper pins can be configured for edge detection, or level detection with or without filtering, or active tamper which increases the security level by auto checking that the tamper pins are not externally opened or shorted. Add support for the device-tree configuration of internal and external tamper events as well as the list hardware mapped pins with their associated tamper ID for external tampers. While there, fix the license for this driver. Signed-off-by: Gatien Chevallier <gatien.chevallier@foss.st.com> Acked-by: Etienne Carriere <etienne.carriere@foss.st.com>
