Configures the required pdata and registers the pruss_uio platform device on the DA850 EVM. Tested on AM180x-EVM using the PRU_memAccessPRUDataRam and PRU_memAccessL3andDDR examples from the PRU userspace tools available from http://www.ti.com/tool/sprc940 Signed-off-by: Matt Porter <redacted> --- arch/arm/mach-davinci/board-da850-evm.c | 12 ++++++++++++ 1 file changed, 12 insertions(+)
