I currently don't have HW to test this driver. Then leave that if as-is and only add a comment detailing what needs to be done (rather than just "FIXME"). This "if (1)" is just too odd and will likely trigger code checker warnings. > >> >>> WR(0x4c,0x38); >>> WR(0x4d,0x88); >> [...] >> >> MBR, Sergey >> > >
