Signed-off-by: Lukasz Majewski l.majewski@samsung.com Signed-off-by: Kyungmin Park kyungmin.park@samsung.com Cc: Minkyu Kang mk7.kang@samsung.com --- Changes for v2: - Define separate *p_{} pointer instances for each power device available at Trats - Only basic checks performed - Core responsible for battery charging moved to separate file - ./drivers/power/bat_trats.c
Changes for v3: - None Changes for v3: - change code according to struct pmic redesign --- board/samsung/trats/trats.c | 29 +++++++++++++++++++++++++++++ 1 files changed, 29 insertions(+), 0 deletions(-)
