This series for the Octeon i2c driver is an attempt to upstream some bug fixes and features that accumulated for some time. On top of the Octeon changes a i2c driver for the ThunderX SOC is added which uses the same functional block as the Octeon driver. Patches #1-9 are forward-ports of Octeon features and bugfixes. Patches #10-12 prepare for the driver split. Patches #13-14 add the ThunderX driver. Patches are on top of 4.6-rc1 and were tested on OCTEON, OCTEON-78 and ThunderX. Changes to v4: - Splitted the High-Level Controller patch into several patches - Reworded some commit messages Changes to v3: - Added more functionality flags for SMBUS - Removed both module parameters - Make xfer return also other errors than EGAIN - Return EPROTO on invalid SMBUS block length - Use devm_ioremap_resource - Added rename-only patch - Removed kerneldoc patch from series - Improved defines Changes to v2: - Split clenaup patch into several patches - Strictly moved functional changes to later patches - Fixed do-while checkpatch errors - Moved defines to the patches that use them - Use BIT_ULL macro - Split ThunderX patch into 2 patches Changes to v1: - Fixed compile error on x86_64 - Disabled thunderx driver on MIPS - Re-ordered some thunderx probe functions for readability - Fix missing of_irq.h and i2c-smbus.h includes - Use IS_ENABLED for CONFIG options Jan ------------------------------------------------- David Daney (3): i2c: octeon: Enable High-Level Controller i2c: octeon: Add support for cn78xx chips i2c: octeon: Add workaround for broken irqs on CN3860 Jan Glauber (8): i2c: octeon: Increase retry default and use fixed timeout value i2c: octeon: Move set-clock and init-lowlevel upward dt-bindings: i2c: Add Octeon cn78xx TWSI i2c: octeon: Move read function before write i2c: octeon: Rename driver to prepare for split i2c: octeon: Split the driver into two parts i2c: thunderx: Add i2c driver for ThunderX SOC i2c: thunderx: Add smbus alert support Peter Swain (3): i2c: octeon: Improve error handling i2c: octeon: Flush TWSI writes with readback i2c: octeon: Faster operation when IFLG signals late .../devicetree/bindings/i2c/i2c-octeon.txt | 6 + drivers/i2c/busses/Kconfig | 10 + drivers/i2c/busses/Makefile | 3 + drivers/i2c/busses/i2c-cavium.c | 822 +++++++++++++++++++++ drivers/i2c/busses/i2c-cavium.h | 212 ++++++ drivers/i2c/busses/i2c-octeon-core.c | 283 +++++++ drivers/i2c/busses/i2c-octeon.c | 600 --------------- drivers/i2c/busses/i2c-thunderx-core.c | 303 ++++++++ 8 files changed, 1639 insertions(+), 600 deletions(-) create mode 100644 drivers/i2c/busses/i2c-cavium.c create mode 100644 drivers/i2c/busses/i2c-cavium.h create mode 100644 drivers/i2c/busses/i2c-octeon-core.c delete mode 100644 drivers/i2c/busses/i2c-octeon.c create mode 100644 drivers/i2c/busses/i2c-thunderx-core.c -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe linux-i2c" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
