But the SoCs being targeted with this patch are the ARM + DSP variants. Using 66AK2x is more appropriate. http://www.ti.com/lsds/ti/processors/dsp/c6000_dsp-arm/66ak2x/overview.page Also, DA8xx includes DA830 which is pin-compatible with AM17x. So you can shorten the list of supported processors to DA8xx/66AK2x. > These SoCs have standard 8250 registers plus some extra non-standard > registers. > > The UART will not function unless the non-standard Power and Emulation > Management Register (PWREMU_MGMT) is configured correctly.
