[PATCH v10 09/10] crypto: qce: core: Make clocks optional

From: Vladimir Zapolskiy <vladimir.zapolskiy@linaro.org>
Date: 2023-02-16 13:15:41
Also in: linux-arm-msm, linux-crypto
Subsystem: crypto api, qualcomm crypto drivers, the rest · Maintainers: Herbert Xu, "David S. Miller", Bartosz Golaszewski, Linus Torvalds

From: Thara Gopinath <thara.gopinath@gmail.com>

On certain Snapdragon processors, the crypto engine clocks are enabled by
default by security firmware and the driver should not handle the clocks.
Make acquiring of all the clocks optional in crypto engine driver, so that
the driver initializes properly even if no clocks are specified in the dt.
