Revert "i2c: boardinfo: Annotate code used in init phase only"

This reverts commit 1a2b423be6a89dd07d5fc27ea042be68697a6a49 because we got a regression report and need time to find out the details. Reported-by: Konrad Dybcio Closes: https://lore.kernel.org/r/29ec0082-4dd4-4120-acd2-44b35b4b9487@oss.qualcomm.com Signed-off-by: Wolfram Sang

i2c: boardinfo: Annotate code used in init phase only

2025-09-25T21:14:50+00:00

Annotate two places in boardinfo code: - __i2c_first_dynamic_bus_num is set in init phase. Annotate it as __ro_after_init to prevent later changes. - i2c_register_board_info() is used in init phase only, so annotate it as __init, allowing to free the memory after init phase. This is safe, see comment: "done in board-specific init code near arch_initcall() time" Signed-off-by: Heiner Kallweit Signed-off-by: Wolfram Sang

i2c: remove 'of_node' member from i2c_boardinfo

There is no user of this member anymore. We can remove it. Reviewed-by: Andi Shyti Reviewed-by: Andy Shevchenko Signed-off-by: Wolfram Sang

i2c: core: Deprecate of_node in struct i2c_board_info

2025-04-16T16:08:47+00:00

Two members of the same or quite similar semantics is quite confusing to begin with. Moreover, fwnode covers all possible firmware descriptions that Linux kernel supports. Deprecate of_node in struct i2c_board_info, so users will be warned and in the future there is a plan to convert the users and remove it completely.

i2c: Introduce i2c_10bit_addr_*_from_msg() helpers

2025-03-18T20:53:53+00:00

There are already a lot of drivers that have been using i2c_8bit_addr_from_msg() for 7-bit addresses, now it's time to have the similar for 10-bit addresses.
