In earlier tests, it was still enabled from a previous boot into the vendor system. Changes in V4: - use dev_err_probe in clk probe() - R-by Changes in V3: - maintainer change in binding doc - fix references to binding doc - additionalProperties: false - remove subdevices also from examples until subdevices are referenced/added Changes in V2: - no separate device node for the clock - converted toplevel node of TWL Andreas Kemnade (5): dt-bindings: mfd: convert twl-family.txt to json-schema dt-bindings: mfd: ti,twl: Add clock provider properties mfd: twl-core: Add a clock subdevice for the TWL6032 clk: twl: add clock driver for TWL6032 ARM: dts: omap4-embt2ws: enable 32K clock on WLAN .../bindings/input/twl4030-pwrbutton.txt | 2 +- .../devicetree/bindings/mfd/ti,twl.yaml | 67 ++++++ .../devicetree/bindings/mfd/twl-family.txt | 46 ---- .../boot/dts/ti/omap/omap4-epson-embt2ws.dts | 8 + drivers/clk/Kconfig | 9 + drivers/clk/Makefile | 1 + drivers/clk/clk-twl.c | 197 ++++++++++++++++++ drivers/mfd/twl-core.c | 16 ++ 8 files changed, 299 insertions(+), 47 deletions(-) create mode 100644 Documentation/devicetree/bindings/mfd/ti,twl.yaml delete mode 100644 Documentation/devicetree/bindings/mfd/twl-family.txt create mode 100644 drivers/clk/clk-twl.c
