Add the max8997 controller for Driver model. Exynos4210 is using max8997 pmic controller. (pmic_max8997.c should be deprecated.)
Signed-off-by: Jaehoon Chung jh80.chung@samsung.com Reviewed-by: Simon Glass sjg@chromium.org
Applied on pmic branch of u-boot-mmc. Thanks!
Best Regards, Jaehoon Chung
Changelog on V2:
- Add the descirption in more detail
- Change from DM_PMIC_MAX8997 to PMIC_MAX8997
- Fixes header file ordering
