Subject: [PATCH v2 1/4] pinctrl: qcom: spmi-gpio: add support for LV_VIN2 and MV_VIN3 subtypes
From: David Collins <quic_collinsd@...cinc.com>
Add support for SPMI PMIC GPIO subtypes GPIO_LV_VIN2 and
GPIO_MV_VIN3.
GPIO_LV_VIN2 GPIOs support two input reference voltages: VIN0 and
VIN1. These are typically connected to 1.8 V and 1.2 V supplies
respectively.
GPIO_MV_VIN3 GPIOs support three input reference voltages: VIN0,
VIN1, and VIN2. These are typically connected to Vph, 1.8 V, and
1.2 V supplies respectively.
