The LDB is either part of the IOMUX_GPR (i.MX6SX) or the BLKCTRL (i.MX8MP, i.MX93) register space. Both IOMUX_GPR and BLKCTRL are register ranges with loose register definitions. E.g. - On the i.MX8MP there is one register which controls the AXI threshold for two different IPs (BIT(31:16) - IP1, BIT(15:0) - IP2). - On the i.MX6SX IOMUXC_GPR5 controlls: CSI2 mux, WDOG3 settings, PXP handshake, ... In conclusion: it can't be ensured that one register belongs to one dedicated IP and the LDB is rather an exception than the rule. Therefore remove the 'reg' and 'reg-names' property requirement.
