Hi, This patchset add devm_pm_opp_set_clkname, devm_pm_opp_put_clkname, devm_pm_opp_set_regulators, devm_pm_opp_put_regulators, devm_pm_opp_set_supported_hw, devm_pm_opp_of_add_table and devm_pm_opp_register_notifier. Yangtao Li (31): opp: Add devres wrapper for dev_pm_opp_set_clkname and dev_pm_opp_put_clkname opp: Add devres wrapper for dev_pm_opp_set_regulators and dev_pm_opp_put_regulators opp: Add devres wrapper for dev_pm_opp_set_supported_hw opp: Add devres wrapper for dev_pm_opp_of_add_table opp: Add devres wrapper for dev_pm_opp_register_notifier serial: qcom_geni_serial: fix potential mem leak in qcom_geni_serial_probe() serial: qcom_geni_serial: convert to use devm_pm_opp_* API spi: spi-qcom-qspi: fix potential mem leak in spi_geni_probe() spi: spi-qcom-qspi: fix potential mem leak in spi_geni_probe() qcom-geni-se: remove opp_table mmc: sdhci-msm: fix potential mem leak in sdhci_msm_probe() mmc: sdhci-msm: convert to use devm_pm_opp_* API spi: spi-qcom-qspi: fix potential mem leak in qcom_qspi_probe() spi: spi-qcom-qspi: convert to use devm_pm_opp_* API drm/msm: fix potential mem leak drm/msm: convert to use devm_pm_opp_* API and remove dp_ctrl_put drm/lima: convert to use devm_pm_opp_* API drm/lima: remove unneeded devm_devfreq_remove_device() drm/panfrost: convert to use devm_pm_opp_* API media: venus: fix error check in core_get_v4() media: venus: convert to use devm_pm_opp_* API memory: samsung: exynos5422-dmc: fix return error in exynos5_init_freq_table memory: samsung: exynos5422-dmc: convert to use devm_pm_opp_* API memory: tegra20: convert to use devm_pm_opp_* API memory: tegra30: convert to use devm_pm_opp_* API PM / devfreq: tegra30: convert to use devm_pm_opp_* API PM / devfreq: rk3399_dmc: convert to use devm_pm_opp_* API PM / devfreq: imx8m-ddrc: convert to use devm_pm_opp_* API PM / devfreq: imx-bus: convert to use devm_pm_opp_* API PM / devfreq: exynos: convert to use devm_pm_opp_* API PM / devfreq: convert to devm_pm_opp_register_notifier and remove unused API drivers/devfreq/devfreq.c | 66 +------ drivers/devfreq/exynos-bus.c | 42 +---- drivers/devfreq/imx-bus.c | 14 +- drivers/devfreq/imx8m-ddrc.c | 15 +- drivers/devfreq/rk3399_dmc.c | 22 +-- drivers/devfreq/tegra30-devfreq.c | 21 +-- drivers/gpu/drm/lima/lima_devfreq.c | 45 +---- drivers/gpu/drm/lima/lima_devfreq.h | 2 - drivers/gpu/drm/msm/adreno/a5xx_gpu.c | 2 +- drivers/gpu/drm/msm/adreno/a6xx_gmu.c | 2 +- drivers/gpu/drm/msm/adreno/adreno_gpu.c | 2 +- drivers/gpu/drm/msm/disp/dpu1/dpu_kms.c | 31 ++-- drivers/gpu/drm/msm/disp/dpu1/dpu_kms.h | 2 - drivers/gpu/drm/msm/dp/dp_ctrl.c | 29 +-- drivers/gpu/drm/msm/dp/dp_ctrl.h | 1 - drivers/gpu/drm/msm/dp/dp_display.c | 5 +- drivers/gpu/drm/msm/dsi/dsi_host.c | 23 ++- drivers/gpu/drm/panfrost/panfrost_devfreq.c | 34 +--- drivers/gpu/drm/panfrost/panfrost_devfreq.h | 1 - .../media/platform/qcom/venus/pm_helpers.c | 22 +-- drivers/memory/samsung/exynos5422-dmc.c | 13 +- drivers/memory/tegra/tegra20-emc.c | 29 +-- drivers/memory/tegra/tegra30-emc.c | 29 +-- drivers/mmc/host/sdhci-msm.c | 27 ++- drivers/opp/core.c | 173 ++++++++++++++++++ drivers/opp/of.c | 36 ++++ drivers/spi/spi-geni-qcom.c | 23 ++- drivers/spi/spi-qcom-qspi.c | 25 ++- drivers/tty/serial/qcom_geni_serial.c | 31 ++-- include/linux/devfreq.h | 23 --- include/linux/pm_opp.h | 38 ++++ include/linux/qcom-geni-se.h | 2 - 32 files changed, 402 insertions(+), 428 deletions(-)
