git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux Pull i2c updates from Wolfram Sang: "This pull request contains: - i2c core reorganization. One source file became too monolithic. It is now split up, yet we still have the same named object as the final output. This should ease maintenance. - new drivers: ZTE ZX2967 family, ASPEED 24XX/25XX - designware driver gained slave mode support - xgene-slimpro driver gained ACPI support - bigger overhaul for pca-platform driver - the algo-bit module now supports messages with enforced STOP - slightly bigger than usual set of driver updates and improvements and with much appreciated quality assurance from Andy Shevchenko" * 'i2c/for-4.13' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux: (51 commits) i2c: Provide a stub for i2c_detect_slave_mode() i2c: designware: Let slave adapter support be optional i2c: designware: Make HW init functions static i2c: designware: fix spelling mistakes i2c: pca-platform: propagate error from i2c_pca_add_numbered_bus i2c: pca-platform: correctly set algo_data.reset_chip i2c: acpi: Do not create i2c-clients for LNXVIDEO ACPI devices i2c: designware: enable SLAVE in platform module i2c: designware: add SLAVE mode functions i2c: zx2967: drop COMPILE_TEST dependency i2c: zx2967: always use the same device when printing errors i2c: pca-platform: use dev_warn/dev_info instead of printk i2c: pca-platform: use device managed allocations i2c: pca-platform: add devicetree awareness i2c: pca-platform: switch to struct gpio_desc dt-bindings: add bindings for i2c-pca-platform i2c: cadance: fix ctrl/addr reg write order i2c: zx2967: add i2c controller driver for ZTE's zx2967 family dt: bindings: add documentation for zx2967 family i2c controller i2c: algo-bit: add support for I2C_M_STOP ...

2017-05-31i2c: break out smbus support into separate fileWolfram Sang1-0/+3
Break out the exported SMBus functions and the emulation layer into a separate file. This also involved splitting up the tracing header into an I2C and an SMBus part. Reviewed-by: Andy Shevchenko <andy.shevchenko@gmail.com> Signed-off-by: Wolfram Sang <wsa@the-dreams.de>
2017-05-31i2c: rename core source file to allow refactorizationWolfram Sang1-1/+1
The I2C core became quite huge and its monolithic structure makes maintenance hard. So, prepare to break out some functionality into separate files by renaming the source file. Note that we keep the resulting object name constant to avoid regressions.

It never made sense to keep these documents together; move each into its own file. Drop the section numbering on hsi.txt on its way to its own file. Suggested-by: Sebastian Reichel <sre@kernel.org> Signed-off-by: Jonathan Corbet <corbet@lwn.net>
