By using platform_get_irq instead of platform_get_resource the driver works for sparc. The GRLIB port of the ocores i2c controller needs custom getreg and setreg functions to allow for big endian register access and to deal with the fact that the PRELOW and PREHIGH registers have been merged into one register. Signed-off-by: Andreas Larsson Changes since v3: - Use a separate entry in the of match table for the grlib variant and trigger grlib function usage on type put in the data field of that table entry Andreas Larsson (2): i2c: i2c-ocores: Add irq support for sparc i2c: i2c-ocores: Add support for the GRLIB port of the controller and custom getreg and setreg functions .../devicetree/bindings/i2c/i2c-ocores.txt | 2 +- drivers/i2c/busses/i2c-ocores.c | 90 ++++++++++++++++++-- 2 files changed, 83 insertions(+), 9 deletions(-)
