Message-ID: <20240105-topic-venus_reset-v2-14-c37eba13b5ce@linaro.org> (raw)
In-Reply-To: <20240105-topic-venus_reset-v2-0-c37eba13b5ce@linaro.org>

Some Venus resets may require more time when toggling. Describe that.

The value was obtained by referencing the msm-4.14/19 driver, which uses a
single value for all platforms [1].
