Subject: [PATCH v2 0/3] Support Nuvoton NPCM750 SGPIO
Date:   Tue,  8 Nov 2022 17:28:37 +0800
Message-Id: <20221108092840.14945-1-JJLIU0@nuvoton.com>
Precedence: bulk

NPCM750 include two SGPIO modules.
Each module supports up eight output ports and eight input ports.
And each port have eight pins, so each module supports up to 64 input and 64 output pins.
the output pin must be serial to parallel device(such as the hc595)
the input in must be parallel to serial device(such as the hc165).
