power: supply: rt9471: Simplify definition of some struct linear_range

2025-05-03T17:17:02+00:00

Use LINEAR_RANGE() instead of hand-writing it. It is less verbose. Signed-off-by: Christophe JAILLET Link: https://lore.kernel.org/r/0da94193c5f8b35fa98f25a852d74b841670bd6e.1746197233.git.christophe.jaillet@wanadoo.fr Signed-off-by: Sebastian Reichel

power: supply: all: switch psy_cfg from of_node to fwnode

2025-03-08T00:42:34+00:00

When registering a power-supply device, either a of_node or the more recent fwnode can be supplied. Since fwnode can also contain an of_node, let's try to get rid of it.

power: supply: rt9471: Use IC status regfield to report real charger status

2024-10-16T21:32:51+00:00

Use IC status regfield to rewrite the 'get_staus' function. The original one cannot cover some special scenario like as charger OTG or JEITA case.

power: supply: Change usb_types from an array into a bitmask

2024-09-03T21:20:28+00:00

The bit_types array just hold a list of valid enum power_supply_usb_type values which map to 0 - 9. This can easily be represented as a bitmap. This reduces the size of struct power_supply_desc and further reduces the data section size by drivers no longer needing to store the array. This also unifies how usb_types are handled with charge_behaviours, which allows power_supply_show_usb_type() to be removed.

power: supply: Switch i2c drivers back to use .probe()

2023-06-04T20:33:22+00:00

After commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new() call-back type"), all drivers being converted to .probe_new() and then 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.

power: supply: rt9471: fix using wrong ce_gpio in rt9471_probe()

2023-02-13T20:28:56+00:00

Pass the correct 'ce_gpio' to IS_ERR(), and remove the ce_gpio in chip data, make it all by SW control only, not to control by HW pin.
