   4 Subject: [PATCH 023/117] soc: sunxi: sram: Only iterate over SRAM children
   5
   6 Now that a "regulators" child is accepted by the controller binding, the
   7 debugfs show routine must be explicitly limited to "sram" children.

  22 regulator: Add support for Allwinner D1 LDOs
  23 This series adds bindings and a driver for the two pairs of LDOs
  24 inside the Allwinner D1 SoC.
  25
  26 A binding and driver change is required for the SRAM controller, to
  27 accept the regulators device as its child node. The new example in the
  28 SRAM controller binding uses the compatible string added in this series:
