Comment: The struct is called system_control_registers only because the mxc_nand.c uses that name. For i.MX31 these registers are called "Clock Control Registers" so the struct name should be clock_control_registers, while for i.MX27 they are called "System Control Registers". --- include/asm-arm/arch-mx31/mx31-regs.h | 41 +++++++++++++++++++++++++++++++++ 1 files changed, 41 insertions(+), 0 deletions(-)
