7 title: Nuvoton SGPIO controller
10   - Jim LIU <JJLIU0@nuvoton.com>
13   This SGPIO controller is for NUVOTON NPCM7xx and NPCM8xx SoC and detailed
15   Nuvoton NPCM7xx SGPIO module is combines a serial to parallel IC (HC595)
19   NPCM7xx/NPCM8xx have two sgpio modules. Each module can support up
21   GPIO pins can be programmed to support the following options
22   - Support interrupt option for each input port and various interrupt
23     sensitivity options (level-high, level-low, edge-high, edge-low)
24   - ngpios is number of nuvoton,input-ngpios GPIO lines and nuvoton,output-ngpios GPIO lines.
25     nuvoton,input-ngpios GPIO lines is only for GPI.
26     nuvoton,output-ngpios GPIO lines is only for GPO.
