STRUCT RZA1_PINCTRL(9)
π struct rza1_pinctrl(9) β the RZ pincontroller device, explained π
okay so this is a page from the Kernel API Manual, and bestie, it's literally all about struct rza1_pinctrl β the RZ pincontroller device. yes, that one. let's get into it β¨
πΈ SYNOPSIS πΈ
here's the whole struct, copied exactly, no cap:
struct rza1_pinctrl {
struct device *dev;
struct mutex mutex;
void __iomem *base;
unsigned int nport;
struct rza1_port *ports;
struct pinctrl_pin_desc *pins;
struct pinctrl_desc desc;
struct pinctrl_dev *pctl;
const void *data;
};
like, look at her. main character struct energy fr fr π«Ά
β¨ Members β¨ (aka the whole cast)
devβ the parent device structure. the mom of the group chat πmutexβ protects the[pinctrl|pinmux]_genericfunctions. she's the bouncer at the door, keep her happy π€baseβ logical address base. the literal home address of the whole operation πnportβ number of pin controller ports. counting era π’portsβ pin controller banks. the whole crew π«pinsβ pin array for the pinctrl core. iconic lineup βdescβ pincontroller desc for the pinctrl core. the vibe check sheet πpctlβ pinctrl device. the actual device herself πdataβ device specific data. her personal lore, iykyk π₯
π SEE ALSO π
first up, the kernel file itself: ./drivers/pinctrl/renesas/pinctrl-rza1.c β go read her, she's the source of truth π
and then the whole friend group, all of them linked from here:

no gatekeeping here, she tags everyone π
ngl this one's short and sweet β but every single field matters, so don't skip the mutex. she's protecting the [pinctrl|pinmux]_generic functions and that's not a joke π«‘
and that's the whole page, bestie! this lil' cutie comes from ./drivers/pinctrl/renesas, dated October 2026 β so like, from the future, slay πβ¨π
