Subject: [PATCH] iio: adc: stm32: fix maximum clock rate for stm32mp15x
Date: Thu, 9 Jun 2022 11:52:34 +0200	[thread overview]
Message-ID: <20220609095234.375925-1-olivier.moysan@foss.st.com> (raw)

Change maximum STM32 ADC input clock rate to 36MHz, as specified
in STM32MP15x datasheets.

Fixes: d58c67d1d851 ("iio: adc: stm32-adc: add support for STM32MP1")
