68		 * Utilization of "Hold Register" is already implemented via
69		 * dw_mci_pltfm_prepare_command() which in its turn gets
70		 * used through dw_mci_drv_data->prepare_command call-back.
71		 * This call-back is used in Altera Socfpga platform and so
72		 * we may reuse it saying that we're compatible with their
73		 * "altr,socfpga-dw-mshc".
74		 *
75		 * Most probably "Hold Register" utilization is platform-
76		 * independent requirement which means that single unified
77		 * "snps,dw-mshc" should be enough for all users of DW MMC once
78		 * dw_mci_pltfm_prepare_command() is used in generic platform
