Subject: [PATCH v2 01/15] dt-bindings: ufs: common: add OPP table
Date: Thu, 20 Jul 2023 11:10:46 +0530 [thread overview]
Message-ID: <20230720054100.9940-2-manivannan.sadhasivam@linaro.org> (raw)
In-Reply-To: <20230720054100.9940-1-manivannan.sadhasivam@linaro.org>
From: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>
Except scaling UFS and bus clocks, it's necessary to scale also the
voltages of regulators or power domain performance state levels. Adding
Operating Performance Points table allows to adjust power domain
performance state, depending on the UFS clock speed.
OPPv2 deprecates previous property limited to clock scaling:
freq-table-hz.
