Merge branch 'i2c/for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux
Pull i2c updates from Wolfram Sang: "Most notable: - introducing the i2c_quirk infrastructure. Now, flaws of I2C controllers can be described and the core will check if the flaws collide with the messages to be sent - wait_for_completion return type cleanup series - new drivers for Digicolor, Netlogic XLP, Ingenic JZ4780 - updates to the I2C slave framework which include API changes. Its only user was updated, too. Documentation was finally added - changed dynamic bus numbering for the DT case. This could change bus numbers for users. However, it fixes a collision where dynamic and static busses request the same id. - driver bugfixes, cleanups" * 'i2c/for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux: (52 commits) i2c: xlp9xx: Driver for Netlogic XLP9XX/5XX I2C controller of: Add vendor prefix 'netlogic' i2c: davinci: use ICPFUNC to toggle I2C as gpio for bus recovery i2c: davinci: use bus recovery infrastructure i2c: change input parameter to i2c_adapter for prepare/unprepare_recovery i2c: i2c-mux-gpio: remove error messages for probe deferrals i2c: jz4780: Add i2c bus controller driver for Ingenic JZ4780 i2c: dln2: set the device tree node of the adapter i2c: davinci: fixup wait_for_completion_timeout handling i2c: mpc: Fix ISR return value i2c: slave-eeprom: add more info when to increase the pointer i2c: slave: add documentation for i2c-slave-eeprom Documentation: i2c: describe the new slave mode i2c: slave: rework the slave API i2c: add support for the Digicolor I2C controller i2c: busses with dynamic ids should start after fixed ids for DT of: base: add function to get highest id of an alias stem i2c: designware: Suppress error message if platform_get_irq() < 0 i2c: mpc: assign the correct prescaler from SVR i2c: img-scb: fixup of wait_for_completion_timeout return handling ...
