Those driver are not DM drivers per se (not using the PMIC/regulator framework) and are using the legacy I2C API. Make them compatible with the DM_I2C API. This impacts the following drivers: - palmas (used by am57xx/dra7xx evms) - tps65218 (used by am43xx evms) - tps65217 and tps65910 (used by am335x evms and am335x boneblack vboot) - twl4030 (used by omap3_logicpd) - tps65217 (used by brppt1) - twl6030 Signed-off-by: Jean-Jacques Hiblot <jjhiblot@ti.com> Reviewed-by: Tom Rini <trini@konsulko.com> Reviewed-by: Heiko Schocher <hs@denx.de>
