History log of /src/sys/dev/i2c/i2c_subr.c
Revision	Date	Author	Comments
1.7	23-Sep-2025	thorpej	Move iic_{acquire,release}_bus_lock() into i2c_exec.c from i2c_subr.c to deal with MODULARization / attribute entanglements. Fixes e.g. alpha INSTALL kernel build issue after recent i2c work.
1.6	21-Sep-2025	thorpej	...and make sure the bus # is printed in the not-not-configured case, too.
1.5	21-Sep-2025	thorpej	Fix brain-o in last commit (that'll teach me to make last minute changes).
1.4	21-Sep-2025	thorpej	iicbus_print(): report the bus number, if set in the tag.
1.3	20-Sep-2025	thorpej	Put the "acquire i2c bus lock" logic (sleep vs try) into a helper function so it can shared.
1.2	01-Apr-2022	pgoyette	Split i2c_subr.c into a separate module rather than including it in the iic module. There are valid configurations where i2c_subr code can be both built-in and part of a loaded module (eg, piixpm is in the kernel, but the iic module is loaded later). This causes the in-kernel linker to detect a duplicate symbol.
1.1	03-Oct-2011	jmcneill	branches: 1.1.72; 1.1.82; fix build for kernels with i2c host controller drivers but no iic(4) driver present
1.1.82.1	09-Aug-2021	thorpej	Port over the changes from thorpej-i2c-spi-conf to thorpej-i2c-spi-conf2, which is based on a newer HEAD revision.
1.1.72.2	14-May-2021	thorpej	Move the bus/channel number for multi-channel / mux controllers out of i2cbus_attach_args and stash it in the i2c_tag_t instead. This makes it accessible to platform device tree code when enumerating devices.
1.1.72.1	08-May-2021	thorpej	- Add an optional bus number to i2cbus_attach_args, and a corresponding optional "bus" locator to the i2cbus interface attribute. - Add a iicbus_print_multi() routine, which is like iicbus_print(), but also prints the bus number. - Use these new features in the iicmux driver rather than winging it.
