From cc47aed9a1ef8eadd7bf14e32117896777b5cc41 Mon Sep 17 00:00:00 2001 From: Inha Song Date: Sat, 30 Aug 2014 11:27:18 +0900 Subject: mfd: arizona: Add support for INn_Mode register control 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 less than or equal to the number of input singals. If values less than the number of input signals, elements that has not been specifed are set to 0 by default. Example: - wlf,inmode = <2 0 2>; /* IN1, IN3 use DMIC */ Signed-off-by: Inha Song Reviewed-by: Charles Keepax Signed-off-by: Lee Jones --- drivers/mfd/arizona-core.c | 13 +++++++++++++ 1 file changed, 13 insertions(+) diff --git a/drivers/mfd/arizona-core.c b/drivers/mfd/arizona-core.c index 7eabc36b97c1..4afb232b5cde 100644 --- a/drivers/mfd/arizona-core.c +++ b/drivers/mfd/arizona-core.c @@ -534,7 +534,11 @@ EXPORT_SYMBOL_GPL(arizona_of_get_named_gpio); static int arizona_of_get_core_pdata(struct arizona *arizona) { struct arizona_pdata *pdata = &arizona->pdata; + struct property *prop; + const __be32 *cur; + u32 val; int ret, i; + int count = 0; pdata->reset = arizona_of_get_named_gpio(arizona, "wlf,reset", true); @@ -560,6 +564,15 @@ static int arizona_of_get_core_pdata(struct arizona *arizona) ret); } + of_property_for_each_u32(arizona->dev->of_node, "wlf,inmode", prop, + cur, val) { + if (count == ARRAY_SIZE(arizona->pdata.inmode)) + break; + + arizona->pdata.inmode[count] = val; + count++; + } + return 0; } -- cgit v1.2.3
