Still looks pretty nice, just thought of some things if
you're anyway working on the code:

+       return regmap_update_bits(gpio->lp873->regmap, LP873X_REG_GPO_CTRL,
+                                 BIT(offset * 4), value ? BIT(offset * 4) : 0);

(...)
(...)

+       return val & BIT(offset * 4);

(...)

+       regmap_update_bits(gpio->lp873->regmap, LP873X_REG_GPO_CTRL,
+                          BIT(offset * 4), value ? BIT(offset * 4) : 0);

(...)

+               return regmap_update_bits(gpio->lp873->regmap,
+                                         LP873X_REG_GPO_CTRL,
+                                         BIT(offset * 4 + 2),
+                                         BIT(offset * 4 + 2));
+       case LINE_MODE_PUSH_PULL:
+               return regmap_update_bits(gpio->lp873->regmap,
+                                         LP873X_REG_GPO_CTRL,
+                                         BIT(offset * 4 + 2), 0);

This 4 +2 etc business is a bit hard to understand, could you create
a macro with a clever name that makes it more understandable?

Yours,
