It works with Type-C Port Controller Manager to provide USB PD and USB Type-C functionalities. v1 to v2 1. Add fix to Prevent the race condition from interrupt and tcpci port unregister during module remove. v2 to v3 1. Change comment style for the head of source code. 2. No need to print error for platform_get_irq_byname. 3. Fix tcpci_register_port check from IS_ERR_OR_NULL to IS_ERR. 4. Rename driver/Kconfig/Makefile form mt6360 to mt636x. 5. Rename DT binding documents from mt6360 to mt636x.
