Subject: [RFC PATCH v2 2/4] arm64: dts: sdm845: add Inline Crypto Engine registers and clock
Date: Tue, 3 Mar 2020 22:49:40 -0800 [thread overview]
Message-ID: <20200304064942.371978-3-ebiggers@kernel.org> (raw)
In-Reply-To: <20200304064942.371978-1-ebiggers@kernel.org>
From: Eric Biggers <ebiggers@google.com>
Add the vendor-specific registers and clock for Qualcomm ICE (Inline
Crypto Engine) to the device tree node for the UFS host controller on
sdm845, so that the ufs-qcom driver will be able to use inline crypto.
Use a separate register range rather than extending the main UFS range
because there's a gap between the two, and the ICE registers are
vendor-specific. (Actually, the hardware claims that the ICE range also
includes the array of standard crypto configuration registers; however,
on this SoC the Linux kernel isn't permitted to access them directly.)
