[PATCH v3 01/19] iio: adc: at91-sama5d2_adc: fix AT91_SAMA5D2_MR_TRACKTIM_MAX

From: Claudiu Beznea <hidden>
Date: 2022-08-03 10:27:35
Also in: linux-devicetree, linux-iio, lkml
Subsystem: iio subsystem and drivers, microchip sama5d2-compatible adc driver, the rest · Maintainers: Jonathan Cameron, Eugen Hristev, Linus Torvalds

All ADC HW versions handled by this driver (SAMA5D2, SAM9X60, SAMA7G5)
have MR.TRACKTIM on 4 bits. Fix AT91_SAMA5D2_MR_TRACKTIM_MAX to reflect
this.

Fixes: 27e177190891 ("iio:adc:at91_adc8xx: introduce new atmel adc driver")
