It can be turned off when unused to save power. This series introduces the driver for it and lets the DSI driver consume it. Signed-off-by: Konrad Dybcio Reviewed-by: Rob Herring --- Changes in v2: - Remove "|" from bindings description - fix 'renegator' typo - define number of 'reg' - adjust reg= to size/address-cells = 1 - fix regmap usage - use C++ comments for the header - remove now-unused struct qcom_refgen - use common helpers for sm8250 refgen (simple bit ops) - add missing FIELD_PREPs (small brain forgot regmap_update_bits doesn't do shifting) - pick up tags - Link to v1: https://lore.kernel.org/r/20230628-topic-refgen-v1-0-126e59573eeb@linaro.org --- Konrad Dybcio (4): dt-bindings: regulator: Describe Qualcomm REFGEN regulator regulator: Introduce Qualcomm REFGEN regulator driver dt-bindings: display/msm: dsi-controller-main: Allow refgen-supply drm/msm/dsi: Hook up refgen regulator .../bindings/display/msm/dsi-controller-main.yaml | 4 + .../regulator/qcom,sdm845-refgen-regulator.yaml | 57 ++++++++ drivers/gpu/drm/msm/dsi/dsi_cfg.c | 2 + drivers/regulator/Kconfig | 10 ++ drivers/regulator/Makefile | 1 + drivers/regulator/qcom-refgen-regulator.c | 154 +++++++++++++++++++++ 6 files changed, 228 insertions(+) --- base-commit: 5c875096d59010cee4e00da1f9c7bdb07a025dc2 change-id: 20230628-topic-refgen-14fb0b762115 Best regards,
