The Avago APDS9930 has the same register set as the TAOS/AMS TSL2772 so this patch adds the correct device tree bindings and the appropriate LUX table values based on the values in the datasheet. Driver was tested on a LG Nexus 5 (hammerhead) phone. avago,apds9930 datasheet: https://www.mouser.com/datasheet/2/678/avago_AV02-3190EN_DS_APDS-9930_2014-03-25[1]-1217273.pdf tsl2772 datasheet: https://ams.com/eng/content/download/291503/1066377/file/TSL2772_DS000181_2-00.pdf Signed-off-by: Brian Masney <masneyb@xxxxxxxxxxxxx> --- .../devicetree/bindings/iio/light/tsl2772.txt | 1 + drivers/iio/light/tsl2772.c | 18 ++++++++++++++++-- 2 files changed, 17 insertions(+), 2 deletions(-) diff --git a/Documentation/devicetree/bindings/iio/light/tsl2772.txt b/Documentation/devicetree/bindings/iio/light/tsl2772.txt index bfde8b2c8790..e842db749ab2 100644 --- a/Documentation/devicetree/bindings/iio/light/tsl2772.txt +++ b/Documentation/devicetree/bindings/iio/light/tsl2772.txt @@ -13,6 +13,7 @@ Required properties: "amstaos,tmd2672" "amstaos,tsl2772" "amstaos,tmd2772" + "avago,apds9930" - reg: the I2C address of the device Optional properties: diff --git a/drivers/iio/light/tsl2772.c b/drivers/iio/light/tsl2772.c index f6a27f8b3ca7..e5b449aec20c 100644 --- a/drivers/iio/light/tsl2772.c +++ b/drivers/iio/light/tsl2772.c @@ -119,7 +119,8 @@ enum { tsl2672, tmd2672, tsl2772, - tmd2772 + tmd2772, + apds9930, }; enum { @@ -201,6 +202,12 @@ static const struct tsl2772_lux tmd2x72_lux_table[TSL2772_DEF_LUX_TABLE_SZ] = { { 0, 0 }, }; +static const struct tsl2772_lux apds9930_lux_table[TSL2772_DEF_LUX_TABLE_SZ] = { + { 52000, 96824 }, + { 38792, 67132 }, + { 0, 0 }, +}; + static const struct tsl2772_lux *tsl2772_default_lux_table_group[] = { [tsl2571] = tsl2x71_lux_table, [tsl2671] = tsl2x71_lux_table, @@ -212,6 +219,7 @@ static const struct tsl2772_lux *tsl2772_default_lux_table_group[] = { [tmd2672] = tmd2x72_lux_table, [tsl2772] = tsl2x72_lux_table, [tmd2772] = tmd2x72_lux_table, + [apds9930] = apds9930_lux_table, }; static const struct tsl2772_settings tsl2772_default_settings = { @@ -262,6 +270,7 @@ static const int tsl2772_int_time_avail[][6] = { [tmd2672] = { 0, 2730, 0, 2730, 0, 699000 }, [tsl2772] = { 0, 2730, 0, 2730, 0, 699000 }, [tmd2772] = { 0, 2730, 0, 2730, 0, 699000 }, + [apds9930] = { 0, 2730, 0, 2730, 0, 699000 }, }; static int tsl2772_int_calibscale_avail[] = { 1, 8, 16, 120 }; @@ -287,7 +296,8 @@ static const u8 device_channel_config[] = { [tsl2672] = PRX2, [tmd2672] = PRX2, [tsl2772] = ALSPRX2, - [tmd2772] = ALSPRX2 + [tmd2772] = ALSPRX2, + [apds9930] = ALSPRX2, }; static int tsl2772_read_status(struct tsl2772_chip *chip) @@ -501,6 +511,7 @@ static int tsl2772_get_prox(struct iio_dev *indio_dev) case tmd2672: case tsl2772: case tmd2772: + case apds9930: if (!(ret & TSL2772_STA_PRX_VALID)) { ret = -EINVAL; goto prox_poll_err; @@ -1325,6 +1336,7 @@ static int tsl2772_device_id_verif(int id, int target) case tmd2672: case tsl2772: case tmd2772: + case apds9930: return (id & 0xf0) == SWORDFISH_ID; } @@ -1852,6 +1864,7 @@ static const struct i2c_device_id tsl2772_idtable[] = { { "tmd2672", tmd2672 }, { "tsl2772", tsl2772 }, { "tmd2772", tmd2772 }, + { "apds9930", apds9930}, {} }; @@ -1868,6 +1881,7 @@ static const struct of_device_id tsl2772_of_match[] = { { .compatible = "amstaos,tmd2672" }, { .compatible = "amstaos,tsl2772" }, { .compatible = "amstaos,tmd2772" }, + { .compatible = "avago,apds9930" }, {} }; MODULE_DEVICE_TABLE(of, tsl2772_of_match); -- 2.17.1 -- To unsubscribe from this list: send the line "unsubscribe linux-iio" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
