From mboxrd@z Thu Jan 1 00:00:00 1970 From: Ilia Lin Subject: [PATCH 0/2] Add SAW support to QCOM SPMI driver Date: Sun, 4 Mar 2018 14:31:47 +0200 Message-ID: <1520166709-554-1-git-send-email-ilialin@codeaurora.org> Mime-Version: 1.0 Content-Type: text/plain; charset=y Content-Transfer-Encoding: 8bit Return-path: Sender: linux-kernel-owner@vger.kernel.org To: linux-kernel@vger.kernel.org, devicetree@vger.kernel.org, lgirdwood@gmail.com, broonie@kernel.org, robh@kernel.org, mark.rutland@arm.com Cc: ilialin@codeaurora.org, amit.kucheria@linaro.org, nicolas.dechesne@linaro.org, celster@codeaurora.org, tfinkel@codeaurora.org List-Id: devicetree@vger.kernel.org The SAW is the “Subsystem Power Manager (SPM), Adaptive Voltage Scaling (AVS) and Dynamic Current Management (DCM) Wrapper”, that is, a core that contains logic to implement the SPM, AVS, and DCM functions. The SAW manages power controls for a client core such as a CPU. The PMIC regulators supplying power to the CPU cores should not be controlled by the SPMI accesses directly, but through the SAW interface. The patch series adds SAW support to the SPMI regulator driver. The special SAW controlled regulators should be configured by device tree handle. The SPI driver will handle those regulators separately through the SAW interface, instead of SPMI.
