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

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