So, use the data in dt ids table to distinguish them. Signed-off-by: Alexander Morozov [voice.shen@atmel.com: add code to distinguish device type] Signed-off-by: Bo Shen --- Changes in v3: - Get the device type from match data in probe function. Changes in v2: - Add driver data for distinguish the device capability. sound/soc/codecs/wm8904.c | 31 ++++++++++++++++++++++++++++++- 1 file changed, 30 insertions(+), 1 deletion(-) diff --git a/sound/soc/codecs/wm8904.c b/sound/soc/codecs/wm8904.c index 4d2d2b1..a80bc52 100644 --- a/sound/soc/codecs/wm8904.c +++ b/sound/soc/codecs/wm8904.c @@ -2098,6 +2098,24 @@ static const struct regmap_config wm8904_regmap = { .num_reg_defaults = ARRAY_SIZE(wm8904_reg_defaults), }; +#ifdef CONFIG_OF +static enum wm8904_type wm8904_data = WM8904; +static enum wm8904_type wm8912_data = WM8912; + +static const struct of_device_id wm8904_of_match[] = { + { + .compatible = "wlf,wm8904", + .data = &wm8904_data, + }, { + .compatible = "wlf,wm8912", + .data = &wm8912_data, + }, { + /* sentinel */ + } +}; +MODULE_DEVICE_TABLE(of, wm8904_of_match); +#endif + static int wm8904_i2c_probe(struct i2c_client *i2c, const struct i2c_device_id *id) { @@ -2125,7 +2143,17 @@ static int wm8904_i2c_probe(struct i2c_client *i2c, return ret; } - wm8904->devtype = id->driver_data; + if (i2c->dev.of_node) { + const struct of_device_id *match; + + match = of_match_node(wm8904_of_match, i2c->dev.of_node); + if (match == NULL) + return -EINVAL; + wm8904->devtype = *((enum wm8904_type *)match->data); + } else { + wm8904->devtype = id->driver_data; + } + i2c_set_clientdata(i2c, wm8904); wm8904->pdata = i2c->dev.platform_data; @@ -2259,6 +2287,7 @@ static struct i2c_driver wm8904_i2c_driver = { .driver = { .name = "wm8904", .owner = THIS_MODULE, + .of_match_table = of_match_ptr(wm8904_of_match), }, .probe = wm8904_i2c_probe, .remove = wm8904_i2c_remove, -- 2.3.0.rc0
