Note A: External IO voltage (DVDD_GPIO) can be 1.8~3.3V.
Note B: QCA4004 need 3.3V and 1.2V supply. For 1.2V supply there are 2 methods: Switching and LDO.
Inside the QCA4004, there is embedded a switching regulator to convert 3.3V to 1.2V for its chip core
voltage supply. Also it has a LDO driver to act as 3.3V->1.2V LDO driver (might need external transistor). In
