Hi, Charles. Thanks for your review.

Some boards need to set the INn_MODE[1:0] register to change the input signal patch. This wlf,inmode property is optional. If present values must be specified by the number of ARIZONA_MAX_INPUT. Example: - wlf,inmode = <2 0 2 0>; /* IN1, IN3 use DMIC */ Signed-off-by: Inha Song <ideal.song@samsung.com> --- drivers/mfd/arizona-core.c | 4 ++++ 1 file changed, 4 insertions(+)
