Merge tag 'v7.2-rc2' into togreg

2026-07-06T15:59:47+00:00

Linux 7.2-rc2 Done to resolve conflicts with header reorg around mod_devicetable.h and provide a base for other inflight series that touch the includes.

Replace by more specific (c files)

2026-07-03T05:38:17+00:00

Replace the #include of by the more specific where applicable. For most cases the include can be dropped completely, only a few drivers need one or two headers added.

iio: Initialize spi_device_id arrays using member names

2026-06-29T23:15:56+00:00

While being less compact, using named initializers allows to more easily see which members of the structs are assigned which value without having to lookup the declaration of the struct. And it's also more robust against changes to the struct definition. The mentioned robustness is relevant for a planned change to struct spi_device_id that replaces .driver_data by an anonymous union. This patch doesn't modify the compiled arrays, only their representation in source form benefits. The former was confirmed with x86 and arm64 builds.

iio: Drop unused assignment of spi_device_id driver data

2026-06-29T23:15:56+00:00

The drivers explicitly set the .driver_data member of struct spi_device_id to zero without relying on that value. Drop these unused assignments. While touching these arrays unify spacing and use named initializers for .name. This patch doesn't modify the compiled arrays, only their representation in source form benefits. The former was confirmed with x86 and arm64 builds. Signed-off-by: Uwe Kleine-König (The Capable Hub) Reviewed-by: Nuno Sá Signed-off-by: Jonathan Cameron

iio: amplifiers: ad8366: prepare for device-tree support

2026-02-23T21:00:58+00:00

Drop switch case on the enum ID in favor of extended chip info table, containing: - gain_step, indicating with sign the start of the code range; - num_channels, to indicate the number IIO channels; - pack_code() function to describe how SPI buffer is populated; Which allowed for a simplified read_raw() and write_raw() callbacks. The probe() function was adjusted accordingly. The linux/array_size.h include is removed as number of channels is provided by chip info table.
