The data pins of some peripheral are different if connecting to different devices in one pinmux function. In the PPI case, data pins can be used in 8, 16 and 24 pin groups individually. Add these groups into one ppi function. Signed-off-by: Sonic Zhang <sonic.zhang@analog.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
