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 #1-2 are cleanups. Patches #3-10 are forward-ports of Octeon features and bugfixes. Patch #11-12 prepare for the driver split Patches #13-14 add the ThunderX driver. Patches are on top of 4.5 + i2c-octeon-kerneldoc-patch and were tested on OCTEON, OCTEON-78 and ThunderX. 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 (4): i2c-octeon: Support I2C_M_RECV_LEN i2c-octeon: Enable high-level controller and improve on bus contention i2c-octeon: Add support for cn78xx chips i2c-octeon: Add workaround for broken irqs on CN3860 Jan Glauber (8): i2c-octeon: Cleanup i2c-octeon driver i2c-octeon: Cleanup resource allocation code i2c-octeon: Change adapter timeout and retry default values dt-bindings: i2c: Add Octeon cn78xx TWSI 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 (2): 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 | 622 ---------------- drivers/i2c/busses/i2c-thunderx-core.c | 303 ++++++++ 8 files changed, 1639 insertions(+), 622 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
