regulator: qcom_spmi-regulator: Clean-up by using managed work init

2021-03-23T14:22:40+00:00

Few drivers implement remove call-back only for ensuring a delayed
work gets cancelled prior driver removal. Clean-up these by switching
to use devm_delayed_work_autocancel() instead.

Additionally, this helps avoiding mixing devm and manual resource
management and cleans up a (theoretical?) bug where devm managed
over-current IRQ might schedule a new work item after wq was cleaned
at remove().

This change is compile-tested only. All testing is appreciated.

regulator: spmi: Add support for ULT LV_P50 and ULT P300

2021-03-10T12:47:45+00:00

The ULT LV_P50 shares the same configuration as the other ULT LV_Pxxx
and the ULT P300 shares the same as the other ULT Pxxx.

These two regulator types are found on PM8950 and its variants.

regulator: qcom_spmi: Add PM660/PM660L regulators

2020-10-01T20:25:23+00:00

The PM660 PMIC is very often paired with the PM660L option on
SDM630/663/660 (and SDA variants) boards.

The PM660 has 11 "660" LDOs (2 NMOS, 9 PMOS) and 7 HT LDOs (4 NMOS,
3 PMOS) and a quirk: the L4 regulator is unaccessible or does not
exist on the PMIC.
The PM660L has 8 "660" LDOs (1 NMOS, 7 PMOS) and 2 HT NMOS LDOs.

regulator: qcom_spmi: Add support for new regulator types

2020-10-01T20:25:22+00:00

This commit adds the support for some regulator types that are
missing in this driver, such as the ht nmos-ldo, ht-lv nmos-ldo
and new gen n/pmos-ldo, all belonging to the FTSMPS426 register
layout.
This is done in preparation for adding support for the PM660 and
PM660L PMICs.

These are never modified, so make them const to allow the compiler to

regulator: qcom_spmi: Add support for PM8004 regulators

2019-10-01T11:30:03+00:00

This Power IC is used in combination with various PMIC combos,
generally found on boards with MSM8992, MSM8994, MSM8996,
MSM8956, MSM8976 and others, usually at address 0x5 on the SPMI
bus, and its usual usage is to provide power to the GPU and/or
to the CPU clusters (APC0/APC1).
