I will think of that, but I believe this is also up to me. These are driver-local structures, so comments for each structure are not the requirement. Moreover, most of them have clear names.

Indeed.

That might be because Linux is allergic to comments. Everyone is supposed to know already (presumably from birth) how things work :-) Some of them I can guess, but others are not clear - e.g. mux_bits, reg_stride, load_pinctrl... I think it is better that our coding standard requires comments. > > > >>> + unsigned pin; >>> + unsigned muxval; >>> +}; >>> + >>> +struct uniphier_pinctrl_group { >>> + const char *name; >>> + const struct uniphier_pmx_data *pmx_data; >>> + unsigned num_pmx_data; >>> +}; >>> + >>> +struct uniphier_pinctrl_socdata { >>> + const struct uniphier_pinctrl_group *groups; >>> + int groups_count; >>> + const char * const *functions; >>> + int functions_count; >>> + unsigned mux_bits; >>> + unsigned reg_stride; >>> + bool load_pinctrl; >>> +}; >>> + >>> +#define UNIPHIER_PINCTRL_GROUP(grp) \ >>> + { \ >>> + .name = #grp, \ >>> + .pmx_data = grp##_pmx, \ >>> + .num_pmx_data = ARRAY_SIZE(grp##_pmx), \ >>> + } >>> + >>> +struct uniphier_pinctrl_priv { >>> + void __iomem *base; >>> + struct uniphier_pinctrl_socdata *socdata; >>> +}; >>> + >>> +extern const struct pinctrl_ops uniphier_pinctrl_ops; >> >> It's a shame this cannot be static... > > > Indeed.
