There is no need to keep iomuxc_base_regs structure as it serves the exact same purpose of the iomuxc structure, which is to provide access to the GPR registers. The additional fields of iomuxc_base_regs are not used. Other advantage of 'iomuxc' is that it has a shorter name and the variable declarations can fit into a single line. So remove iomuxc_base_regs structure and use iomuxc instead. Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com> Acked-by: Stefano Babic <sbabic@denx.de>
