From addd062beaccc028fccdc90500d5d17647461da6 Mon Sep 17 00:00:00 2001 From: Elaine Zhang Date: Thu, 26 Sep 2019 15:43:54 +0800 Subject: [PATCH] power: pmic: rk816: support rk816 pmic The RK816 is a Power Management IC (PMIC) for multimedia and handheld devices. They contains the following components: - Regulators(4*BUCKs, 1*BOOST, 6*LDOs, 1*SWITCH) - RTC - Clocking Signed-off-by: Elaine Zhang Reviewed-by: Kever Yang --- drivers/power/pmic/rk8xx.c | 1 + drivers/power/regulator/rk8xx.c | 129 ++++++++++++++++++++++++++++++-- include/power/rk8xx_pmic.h | 11 ++- 3 files changed, 135 insertions(+), 6 deletions(-) diff --git a/drivers/power/pmic/rk8xx.c b/drivers/power/pmic/rk8xx.c index 25c339ab12..1900de9d1c 100644 --- a/drivers/power/pmic/rk8xx.c +++ b/drivers/power/pmic/rk8xx.c @@ -95,6 +95,7 @@ static struct dm_pmic_ops rk8xx_ops = { static const struct udevice_id rk8xx_ids[] = { { .compatible = "rockchip,rk808" }, + { .compatible = "rockchip,rk816" }, { .compatible = "rockchip,rk818" }, { } };
