Some sunxi SoCs have in-package regulators controlled by a register in the system control MMIO block. Allow a child node for these regulators in addition to SRAM child nodes. Signed-off-by: Samuel Holland <samuel@sholland.org> --- Changes in v3: - Require the regulators node to have a unit address - Reference the regulator schema from the SRAM controller schema - Move the system LDOs example to the SRAM controller schema - Reorder the patches so the example passes validation Changes in v2: - New patch for v2 .../allwinner,sun4i-a10-system-control.yaml | 29 +++++++++++++++++++ 1 file changed, 29 insertions(+)
