    Subject[PATCH AUTOSEL 4.19 066/167] iio: adc: exynos-adc: Add S5PV210 variant
    Date
    From: Jonathan Bakker <xc-racer2@live.ca>

    [ Upstream commit 882bf52fdeab47dbe991cc0e564b0b51c571d0a3 ]

    S5PV210's ADC variant is almost the same as v1 except that it has 10
    channels and doesn't require the pmu register
