RevisionDateAuthorComments
 1.11  17-Sep-2025  thorpej Don't consult i2c_attach_args::ia_cookietype or ia_cookie when looking
for an FDT / OF phandle; get the information from self's devhandle.
 1.10  16-Sep-2025  thorpej Now that the common I2C code hides many of the FDT vs ACPI differences,
perform the reductions currently possible in the I2C mux layer. Note
some additional enhancements necessary for further reductions.
 1.9  20-Jul-2022  thorpej Improve error reporting.
 1.8  27-Jan-2021  thorpej branches: 1.8.4; 1.8.14;
Use DEVICE_COMPAT_EOL.
 1.7  26-Jan-2021  thorpej Don't map ACPI _HID / _CID strings to "compatible" strings from the
Device Tree bindings. Just pass those strings in the standard
most-specific-to-least-specific order to the drivers and let them
deal.
 1.6  25-Jan-2021  jmcneill Add support for ACPI-based I2C mux attachment.
 1.5  24-Jan-2021  jmcneill remove part of previous that was committed by mistake
 1.4  24-Jan-2021  jmcneill trailing whitespace
 1.3  18-Jan-2021  thorpej Change the device_compatible_match() function to only perform the match.
Introduce a device_compatible_lookup() function to return an entry based
on the same matching criteria (a'la of_search_compatible()).

Update iic_compatible_match() to reflect the above change, and introduce
iic_compatible_lookup(). This pattern is less awkward to use.
 1.2  17-Jan-2021  thorpej Change the device_compatible_entry struct to have a union of
a scalar value (uintptr_t value) and a pointer value (const void *data),
rather than just "uintptr_t data". This eliminates the need for drivers
to cast this value, and doesn't lose const'ness of pointers assigned
to the field.

Update all of the users of this field to use the correct set of
designated initialisers for each specific case.
 1.1  29-Dec-2020  thorpej branches: 1.1.2;
Add a driver for NXP PCA954x / PCA984x I2C switch / mux controllers.
 1.1.2.3  03-Apr-2021  thorpej Sync with HEAD.
 1.1.2.2  03-Jan-2021  thorpej Sync w/ HEAD.
 1.1.2.1  29-Dec-2020  thorpej file pcai2cmux.c was added on branch thorpej-futex on 2021-01-03 16:34:58 +0000
 1.8.14.1  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.
 1.8.4.3  14-May-2021  thorpej No need to device_set_handle(); it's done for us by the i2c enumeration
code.
 1.8.4.2  09-May-2021  thorpej Don't include fdtvar.h directly here.
 1.8.4.1  08-May-2021  thorpej Update the i2c mux code for the new enumeration methods.
