Subject: [PATCH v3] meson saradc: fix clock divider mask length
Date: Tue, 6 Jun 2023 19:53:57 +0300 [thread overview]
Message-ID: <20230606165357.42417-1-gnstark@sberdevices.ru> (raw)
According to datasheets of supported meson SOCs length of ADC_CLK_DIV
field is 6 bits long. Although all supported SOCs have the register
with that field documented later SOCs use external clock rather than
ADC internal clock so this patch affects only meson8 family (S8* SOCs)
Fixes: 3adbf3427330 ("iio: adc: add a driver for the SAR ADC found in Amlogic Meson SoCs")
Signed-off-by: George Stark <GNStark@sberdevices.ru>
