Re: [U-Boot] [linux-sunxi] [PATCH 6/8] power: axp209: Add support for voltage rate control on LDO3

Hi Oliver,

2017-03-01 13:52 GMT+01:00 Olliver Schinagl oliver@schinagl.nl:

+#define AXP209_VRC_LDO3_EN BIT(3) +#define AXP209_VRC_DCDC2_EN BIT(2) +#define AXP209_VRC_LDO3_800uV_uS (BIT(1) | AXP209_VRC_LDO3_EN) +#define AXP209_VRC_LDO3_1600uV_uS AXP209_VRC_LDO3_EN

Does that mean that the description of the LDO3/DCDC2 VRC control on the linux-sunxi wiki [1] and the PDF datasheet [2] are wrong? They say that VRC for LDO3 is enabled if the bit is 0, disabled when the bit is 1. And that the default value is enabled.
