[PATCH 0/2] iio: adc: Add Nuvoton MA35D1 EADC support

[Chi-Wen Weng]

From: Chi-Wen Weng <cwweng at nuvoton.com>

This series adds devicetree binding and IIO driver support for the
Nuvoton MA35D1 Enhanced ADC controller.

The MA35D1 EADC controller supports multiple ADC input channels. This
initial upstream driver supports direct raw reads and triggered buffered
capture using the controller end-of-conversion interrupt as the IIO
device trigger.

ADC channels are described using standard firmware child nodes. Both
single-ended and differential channels are supported. Since the
differential enable bit is global in the controller, mixed single-ended
and differential buffered scans are rejected.

DMA support is intentionally not included in this initial version. The
driver uses the interrupt-driven conversion path to keep the first
upstream submission small and easier to review.

Patch 1 adds the devicetree binding.
Patch 2 adds the MA35D1 EADC IIO driver.
