Can you please fix or remove. What exactly do you have in mind? The s5m8767-clk is already documented as part of clk-s2mps11.c driver: Documentation/devicetree/bindings/mfd/s2mps11.txt The main s5m8767 MFD driver is documented as part of regulator driver: Documentation/devicetree/bindings/regulator/s5m8767-regulator.txt Yes, this may be confusing... They S2M and S5M family devices share: - main mfd driver, - rtc driver, - clk driver. but regulator drivers are separate.
