Changes in v3: - Change the compatible description for more precise. Changes in v2: - Add compatible to support forcibly suspend the ports. - Add soc/at91/at91_sfr.h to accommodate the defines. - Add error checking for .sfr_regmap. - Remove unnecessary regmap_read() statement. - Use the new compatible for ohci-node.
