Subject: [PATCH v4 16/20] crypto: qce: core: Make clocks optional
Date: Wed, 13 Oct 2021 16:25:37 +0530 [thread overview]
Message-ID: <20211013105541.68045-17-bhupesh.sharma@linaro.org> (raw)
In-Reply-To: <20211013105541.68045-1-bhupesh.sharma@linaro.org>
From: Thara Gopinath <thara.gopinath@linaro.org>
On certain Snapdragon processors, the crypto engine clocks are enabled by
default by security firmware and the driver need not/ should not handle the
clocks. Make acquiring of all the clocks optional in crypto enginer driver
so that the driver intializes properly even if no clocks are specified in
the dt.
