Hi, on #maemo IRC channel we have found some accelerometer regulators and I wrote this patch which is working fine with 3.8: @@ -728,12 +730,16 @@ static struct regulator_consumer_supply rx51_vio_supplies[] = { REGULATOR_SUPPLY("DVDD", "2-0019"), /* Si4713 IO supply */ REGULATOR_SUPPLY("vio", "2-0063"), + /* lis3lv02d IO supply */ + REGULATOR_SUPPLY("Vdd_IO", "3-001d"), }; static struct regulator_consumer_supply rx51_vaux1_consumers[] = { REGULATOR_SUPPLY("vdds_sdi", "omapdss"), /* Si4713 supply */ REGULATOR_SUPPLY("vdd", "2-0063"), + /* lis3lv02d supply */ + REGULATOR_SUPPLY("Vdd", "3-001d"), }; static struct regulator_init_data rx51_vaux1 = { Now I see that patch is same as Aaro's :-) so please include it. -- Pali Rohár pali.ro...@gmail.com
