Add support for LDO_510 and FTSMPS3 regulators, all belonging to register layout HFSMPS. This is done in preparation for adding support for the PM6125 PMIC. For FTSMPS3 and LDO_510, only IDLE and NORMAL modes are selectable (no FAST). The inspiration for the magic constants was taken from [1] [1]: https://source.codeaurora.org/quic/la/kernel/msm-5.4/commit/?h=kernel.lnx.5.4.r1-rel&id=d1220daeffaa440ffff0a8c47322eb0033bf54f5 Signed-off-by: Adam Skladowski <a39.skl@xxxxxxxxx> Signed-off-by: Iskren Chernev <iskren.chernev@xxxxxxxxx> --- drivers/regulator/qcom_spmi-regulator.c | 38 ++++++++++++++++++++++++- 1 file changed, 37 insertions(+), 1 deletion(-) diff --git a/drivers/regulator/qcom_spmi-regulator.c b/drivers/regulator/qcom_spmi-regulator.c index 04e9845a9300..0763a5b7a2ce 100644 --- a/drivers/regulator/qcom_spmi-regulator.c +++ b/drivers/regulator/qcom_spmi-regulator.c @@ -99,6 +99,8 @@ enum spmi_regulator_logical_type { SPMI_REGULATOR_LOGICAL_TYPE_ULT_LDO, SPMI_REGULATOR_LOGICAL_TYPE_FTSMPS426, SPMI_REGULATOR_LOGICAL_TYPE_HFS430, + SPMI_REGULATOR_LOGICAL_TYPE_FTSMPS3, + SPMI_REGULATOR_LOGICAL_TYPE_LDO_510, SPMI_REGULATOR_LOGICAL_TYPE_HFSMPS, }; @@ -168,6 +170,16 @@ enum spmi_regulator_subtype { SPMI_REGULATOR_SUBTYPE_HT_P150 = 0x35, SPMI_REGULATOR_SUBTYPE_HT_P600 = 0x3d, SPMI_REGULATOR_SUBTYPE_HFSMPS_510 = 0x0a, + SPMI_REGULATOR_SUBTYPE_FTSMPS_510 = 0x0b, + SPMI_REGULATOR_SUBTYPE_LV_P150_510 = 0x71, + SPMI_REGULATOR_SUBTYPE_LV_P300_510 = 0x72, + SPMI_REGULATOR_SUBTYPE_LV_P600_510 = 0x73, + SPMI_REGULATOR_SUBTYPE_N300_510 = 0x6a, + SPMI_REGULATOR_SUBTYPE_N600_510 = 0x6b, + SPMI_REGULATOR_SUBTYPE_N1200_510 = 0x6c, + SPMI_REGULATOR_SUBTYPE_MV_P50_510 = 0x7a, + SPMI_REGULATOR_SUBTYPE_MV_P150_510 = 0x7b, + SPMI_REGULATOR_SUBTYPE_MV_P600_510 = 0x7d, }; enum spmi_common_regulator_registers { @@ -576,6 +588,14 @@ static struct spmi_voltage_range ht_p600_ranges[] = { SPMI_VOLTAGE_RANGE(0, 1704000, 1704000, 1896000, 1896000, 8000), }; +static struct spmi_voltage_range nldo_510_ranges[] = { + SPMI_VOLTAGE_RANGE(0, 320000, 320000, 1304000, 1304000, 8000), +}; + +static struct spmi_voltage_range ftsmps510_ranges[] = { + SPMI_VOLTAGE_RANGE(0, 300000, 300000, 1372000, 1372000, 4000), +}; + static DEFINE_SPMI_SET_POINTS(pldo); static DEFINE_SPMI_SET_POINTS(nldo1); static DEFINE_SPMI_SET_POINTS(nldo2); @@ -598,6 +618,8 @@ static DEFINE_SPMI_SET_POINTS(ht_nldo); static DEFINE_SPMI_SET_POINTS(hfs430); static DEFINE_SPMI_SET_POINTS(ht_p150); static DEFINE_SPMI_SET_POINTS(ht_p600); +static DEFINE_SPMI_SET_POINTS(nldo_510); +static DEFINE_SPMI_SET_POINTS(ftsmps510); static inline int spmi_vreg_read(struct spmi_regulator *vreg, u16 addr, u8 *buf, int len) @@ -1162,7 +1184,10 @@ spmi_regulator_hfsmps_set_mode(struct regulator_dev *rdev, unsigned int mode) val = SPMI_HFSMPS_MODE_AUTO_MASK; break; case REGULATOR_MODE_IDLE: - val = SPMI_HFSMPS_MODE_LPM_MASK; + val = vreg->logical_type == + SPMI_REGULATOR_LOGICAL_TYPE_FTSMPS3 ? + SPMI_HFSMPS_MODE_RETENTION_MASK : + SPMI_HFSMPS_MODE_LPM_MASK; break; default: return -EINVAL; @@ -1637,6 +1662,16 @@ static const struct spmi_regulator_mapping supported_regulators[] = { SPMI_VREG(ULT_LDO, P300, 0, INF, ULT_LDO, ult_ldo, ult_pldo, 10000), SPMI_VREG(ULT_LDO, P150, 0, INF, ULT_LDO, ult_ldo, ult_pldo, 10000), SPMI_VREG(ULT_LDO, P50, 0, INF, ULT_LDO, ult_ldo, ult_pldo, 5000), + SPMI_VREG(LDO, LV_P150_510, 0, INF, LDO_510, hfsmps, ht_lvpldo, 10000), + SPMI_VREG(LDO, LV_P300_510, 0, INF, LDO_510, hfsmps, ht_lvpldo, 10000), + SPMI_VREG(LDO, LV_P600_510, 0, INF, LDO_510, hfsmps, ht_lvpldo, 10000), + SPMI_VREG(LDO, MV_P50_510, 0, INF, LDO_510, hfsmps, pldo660, 10000), + SPMI_VREG(LDO, MV_P150_510, 0, INF, LDO_510, hfsmps, pldo660, 10000), + SPMI_VREG(LDO, MV_P600_510, 0, INF, LDO_510, hfsmps, pldo660, 10000), + SPMI_VREG(LDO, N300_510, 0, INF, LDO_510, hfsmps, nldo_510, 10000), + SPMI_VREG(LDO, N600_510, 0, INF, LDO_510, hfsmps, nldo_510, 10000), + SPMI_VREG(LDO, N1200_510, 0, INF, LDO_510, hfsmps, nldo_510, 10000), + SPMI_VREG(FTS, FTSMPS_510, 0, INF, FTSMPS3, hfsmps, ftsmps510, 100000), }; static void spmi_calculate_num_voltages(struct spmi_voltage_set_points *points) @@ -1955,6 +1990,7 @@ static int spmi_regulator_of_parse(struct device_node *node, return ret; break; case SPMI_REGULATOR_LOGICAL_TYPE_HFSMPS: + case SPMI_REGULATOR_LOGICAL_TYPE_FTSMPS3: ret = spmi_regulator_init_slew_rate_hfsmps(vreg); if (ret) return ret; -- 2.37.1
