I thing this makes the code easier to follow. I've also cleaned up some other aspects, like the register access and fixed some bugs I found while going over the code again. 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 are on top of 4.6-rc3 and were tested on OCTEON, OCTEON-78 and ThunderX. Changes to v5: - Switch to i2c recovery framework - Clean-up register access, introduce new helper functions - Fixed ready bit check in combined write - Fixed IFLG clear in hlc_enable - Removed complicated last phase logic, not needed when we send START for every message part 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 (14): i2c: octeon: Increase retry default and use fixed timeout value i2c: octeon: Move set-clock and init-lowlevel upward i2c: octeon: Rename [read|write]_sw to reg_[read|write] i2c: octeon: Introduce helper functions for register access i2c: octeon: Remove superfluous check in octeon_i2c_test_iflg i2c: octeon: Improve error status checking i2c: octeon: Use i2c recovery framework 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: octeon,thunderx: Move register offsets to struct 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 | 805 +++++++++++++++++++++ drivers/i2c/busses/i2c-cavium.h | 218 ++++++ drivers/i2c/busses/i2c-octeon-core.c | 288 ++++++++ drivers/i2c/busses/i2c-octeon.c | 600 --------------- drivers/i2c/busses/i2c-thunderx-core.c | 308 ++++++++ 8 files changed, 1638 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
