Merge branch 'i2c/for-4.13' of 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 ...
