+
+description: |
+ This SGPIO controller is for NUVOTON NPCM7xx and NPCM8xx SoC and detailed
+ information is in the NPCM7XX/8XX SERIAL I/O EXPANSION INTERFACE section.
+ Nuvoton NPCM7xx SGPIO module is combines a serial to parallel IC (HC595)
+ and a parallel to serial IC (HC165).
+ Clock is a division of the APB3 clock.
+ This interface has 4 pins (D_out , D_in, S_CLK, LDSH).
+ NPCM7xx/NPCM8xx have two sgpio modules. Each module can support up
+ to 64 output pins, and up to 64 input pins, the pin is only for GPI or GPO.
+ GPIO pins can be programmed to support the following options
+ - Support interrupt option for each input port and various interrupt
+ sensitivity options (level-high, level-low, edge-high, edge-low)
+ - ngpios is number of nuvoton,input-ngpios GPIO lines and nuvoton,output-ngpios GPIO lines.
+ nuvoton,input-ngpios GPIO lines is only for GPI.
+ nuvoton,output-ngpios GPIO lines is only for GPO.
