"usb_types" is very similar in that: 1. It is an enum 2. The list of available values is stored in power_supply_desc 3. When shown it shows all available values, with the active one surrounded by square brackets. But "usb_types" uses an array with valid enum values instead of a bitmask. This uses more memory then the bitmap approach and it makes it impossible to have a shared generic show() function for properties which show available values, with the active one surrounded by square brackets. This patch-set moves "usb_types" over to a bitmask in power_supply_desc to indicate the available values. Patches 1 - 3: It turns out that the ucs1002-power driver contained a surprise in that it supports writing to "usb_type" even though the ABI doc says it is read-only. Since we cannot break shipped userspace API, the ship has sailed on this one. The first patch documents that writing "usb_type" is allowed, but only for power-supply devices which provide USB power rather then consume it. Enum properties accept writing the FOO_TEXT[] string values, passing the enum value matching the FOO_TEXT entry to set_property(), the second patch adjusts ucs1002_set_usb_type() to directly accept enum values. The rt9467 driver was another driver which allowed writing to "usb_type" but there the use made no sense, so it is simply dropped. Patches 4 - 6: These patches implement the actual moving of usb_types to a bitmask. Patch 6 is a bit of a bigbang patch moving all drivers over in one go, touching a couple of drivers outside drivers/power/supply: 1 in drivers/extcon/ 1 in drivers/phy/ and 5 in drivers/usb/typec/ since the changes outside of drivers/power/supply are small I've chosen to make all the changes in one go rather then have some sort of intermediate state where both ways are supported. For merging this I believe it would be best for an immutable branch / tag to be created on the linux-power-supply tree and then send a pull-request to the extcon, phy and usb-typec maintainers to merge the tag. extcon, phy and typec maintainers can you please give your Acked-by for patch 6/6 for merging these changes through the linux-power-supply tree? This set is based on top of the latest linux-power-supply/for-next.
