regulator: max77857: Constify struct regmap_config

2024-07-04T18:15:55+00:00

`max77857_remgap_config` is not modified and can be declared as const to
move its data to a read-only section.

regulator: max77857: Fix Wvoid-pointer-to-enum-cast warning

2023-08-10T14:44:45+00:00

'id' is an enum, thus cast of pointer on 64-bit compile test with W=1
causes:

  max77857-regulator.c:56:24: error: cast to smaller integer type 'enum max77857_id' from 'void *' [-Werror,-Wvoid-pointer-to-enum-cast]

regulator: max77857: fix build error in max77857-regulator.c

2023-08-03T14:57:36+00:00

When using low verion gcc(7.5) to build the max77857-regulator driver,
got the following error:

drivers/regulator/max77857-regulator.c:312:16: error: initializer element is not constant
  .ramp_delay = max77857_ramp_table[0][0],

To fix this by introducing a macro RAMAP_DELAY_INIT_VAL to define the
value of max77857_ramp_table[0[0].

regulator: max77857: change some variables to static

2023-08-01T15:02:22+00:00

max77857_regmap_config and max77857_driver are only used
in max77857-regulator.c now, change them to static.

regulator: max77857: mark more functions static

2023-07-19T13:00:47+00:00

A few functions in the new driver are global but only used in this file:

drivers/regulator/max77857-regulator.c:209:5: error: no previous prototype for 'max77859_get_voltage_sel' [-Werror=missing-prototypes]
drivers/regulator/max77857-regulator.c:221:5: error: no previous prototype for 'max77859_set_current_limit' [-Werror=missing-prototypes]
drivers/regulator/max77857-regulator.c:235:5: error: no previous prototype for 'max77859_get_current_limit' [-Werror=missing-prototypes]

Mark them static, which produces potentially better code and avoids the warning.

regulator: max77857: Switch back to use struct i2c_driver's .probe()

2023-07-19T13:00:46+00:00

After commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new()
call-back type"), all drivers being converted to .probe_new() and then
commit 03c835f498b5 ("i2c: Switch .probe() to not take an id parameter")
convert back to (the new) .probe() to be able to eventually drop
.probe_new() from struct i2c_driver.

regulator: max77857: Add ADI MAX77857/59/MAX77831 Regulator Support

2023-07-17T05:40:32+00:00

Regulator driver for  MAX77857/59 and MAX77831.
The MAX77857 is a high-efficiency, high-performance
buck-boost converter targeted for systems requiring
a wide input voltage range (2.5V to 16V).

The MAX77859 is high-Efficiency Buck-Boost Converter
for USB-PD/PPS Applications. It has wide input range
(2.5V to 22V)

The MAX77831 is a high-efficiency, high-performance
buck-boost converter targeted for systems requiring
wide input voltage range (2.5V to 16V).
