If anyone has any objections, please let me know. ------------------ From: Rob Herring (Arm) [ Upstream commit 4910aa198d25e5d1067236560ba34ab12bccc677 ] The generic "ngpios" property is encoded as a normal uint32 cell. The pisosr driver stores it in the gpio_chip field, but reading it with a u16 helper does not match the DT property encoding. Read "ngpios" as u32 and keep the existing assignment to the chip field.
