Hi Quentin,

Just a couple of small things in this patch.

Please use drv_get_regmap(pdev->dev.parent, NULL) instead (and drop
axp20x).

+	psy_cfg.of_node = pdev->dev.of_node;
+
+	axp20x_batt->axp_id = (int)of_device_get_match_data(&pdev->dev);

use (uintptr_t) to avoid compiler warnings on systems with sizeof
int != sizeof ptr.
