[PATCH 0/4] iio: proximity: vl53l0x: power sequencing, optional VDDIO, raw I2C ID read

Posted by Petr Hodina via B4 Relay 2 weeks, 5 days ago

Hi,

this series improves robustness and hardware compatibility of the
VL53L0X IIO proximity driver.

Patch 1 and 2 adds support for an optional VDDIO (vio) regulator and documents
it in the device tree binding.

Patch 3 fixes the reset and power-up sequencing. The previous logic drove
the reset GPIO in a way that does not match the datasheet timing and
level requirements.

Patch 4 switches the initial device identification from SMBus helpers to
raw I2C transfers and reads the full 16-bit model and revision IDs.

The series has been tested on hardware - Sony Xperia XZ3 (akatsuki).
