Grant Likely 3f07af494d of: adapt of_find_i2c_driver() to be usable by SPI also
SPI has a similar problem as I2C in that it needs to determine an
appropriate modalias value for each device node.  This patch adapts
the of_i2c of_find_i2c_driver() function to be usable by of_spi also.

Wolfram Sang 11d579ee0a powerpc/mpc5200: Fix wrong 'no interrupt' handling in of_i2c
If an I2C device node does not specify an interrupt, the .irq member of the
board_info struct was set to -1. This caused crashes on following
irq_dispose_mappings. Leave it NO_IRQ as returned from irq_of_parse_and_map.
(Suggesting -1 as 'i2c-no-irq' used to be a bug in linux/i2c.h.)

Robert P. J. Day f40987b64d OpenFirmware: Include <linux/of_i2c.h> from of_i2c.c.
drivers/of/of_i2c.c should include <linux/of_i2c.h> for the prototype
for of_register_i2c_devices().

Jean Delvare f2eb432715 rtc-ds1374: rename device to just "ds1374"
Change the name of the device from "rtc-ds1374" to just "ds1374", to match
what all other RTC drivers do.  I seem to remember that this name was
chosen to avoid possible confusion with an older ds1374 driver, but that
driver was removed 3 months ago.

Jochen Friedrich 585468e5d5 [POWERPC] i2c: Fix build breakage introduced by OF helpers
Fix build breakage introduced in commit "[POWERPC] i2c: OF helpers for
the i2c API".  If i2c-core is compiled as a module, the helper needs
to be compiled as a module, as well.  Rename i2c.c to of_i2c.c to
avoid name space conflict.

sparc{32,64} allmodconfig breakage.]
