ARM: dts: socfpga: Add a 3.3V fixed regulator node
Without the 3.3V regulator node, the SDMMC driver will give these warnings: dw_mmc ff704000.dwmmc0: No vmmc regulator found dw_mmc ff704000.dwmmc0: No vqmmc regulator found This patch adds the regulator node, and points the SD/MMC to the regulator. Signed-off-by: Dinh Nguyen <dinguyen@opensource.altera.com> Reviewed-by: Doug Anderson <dianders@chromium.org> --- v3: Rename nodes to have schematic-name_regulator and remove "boot-on" and "always-on" v2: Move the regulator nodes to their respective board dts file and correctly rename them to match the schematic
