Subject: [PATCH v2 3/7] dt-bindings: adc: axi-adc: add clocks property
Date: Fri, 26 Apr 2024 17:42:12 +0200 [thread overview]
Message-ID: <20240426-ad9467-new-features-v2-3-6361fc3ba1cc@analog.com> (raw)
In-Reply-To: <20240426-ad9467-new-features-v2-0-6361fc3ba1cc@analog.com>
From: Nuno Sa <nuno.sa@analog.com>
Add a required clock property as we can't access the device registers if
the AXI bus clock is not properly enabled.
Note this clock is a very fundamental one that is typically enabled
pretty early during boot. Independently of that, we should really rely on
it to be enabled.
Reviewed-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>
Fixes: 96553a44e96d ("dt-bindings: iio: adc: add bindings doc for AXI ADC driver")
