Merge branch 'i2c/for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux
Pull i2c changes from Wolfram Sang: - new drivers for exynos5, bcm kona, and st micro - bigger overhauls for drivers mxs and rcar - typical driver bugfixes, cleanups, improvements - got rid of the superfluous 'driver' member in i2c_client struct This touches a few drivers in other subsystems. All acked. * 'i2c/for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux: (38 commits) i2c: bcm-kona: fix error return code in bcm_kona_i2c_probe() i2c: i2c-eg20t: do not print error message in syslog if no ACK received i2c: bcm-kona: Introduce Broadcom I2C Driver i2c: cbus-gpio: Fix device tree binding i2c: wmt: add missing clk_disable_unprepare() on error i2c: designware: add new ACPI IDs i2c: i801: Add Device IDs for Intel Wildcat Point-LP PCH i2c: exynos5: Remove incorrect clk_disable_unprepare i2c: i2c-st: Add ST I2C controller i2c: exynos5: add High Speed I2C controller driver i2c: rcar: fixup rcar type naming i2c: scmi: remove some bogus NULL checks i2c: sh_mobile & rcar: Enable the driver on all ARM platforms i2c: sh_mobile: Convert to clk_prepare/unprepare i2c: mux: gpio: use reg value for i2c_add_mux_adapter i2c: mux: gpio: use gpio_set_value_cansleep() i2c: Include linux/of.h header i2c: mxs: Fix PIO mode on i.MX23 i2c: mxs: Rework the PIO mode operation i2c: mxs: distinguish i.MX23 and i.MX28 based I2C controller ...

-/**
- * struct at24_platform_data - data to set up at24 (generic eeprom) driver
- * @byte_len: size of eeprom in byte
- * @page_size: number of byte which can be written in one go
- * @flags: tunable options, check AT24_FLAG_* defines
- * @setup: an optional callback invoked after eeprom is probed; enables kernel
- code to access eeprom via memory_accessor, see example
- * @context: optional parameter passed to setup()
- *
- * If you set up a custom eeprom type, please double-check the parameters.
- * Especially page_size needs extra care, as you risk data loss if your value
- * is bigger than what the chip actually supports!
- *
- * An example in pseudo code for a setup() callback:
- *
- * void get_mac_addr(struct memory_accessor *mem_acc, void *context)
- * {
- * u8 *mac_addr = ethernet_pdata->mac_addr;
- * off_t offset = context;
- *
- * // Read MAC addr from EEPROM
- * if (mem_acc->read(mem_acc, mac_addr, offset, ETH_ALEN) == ETH_ALEN)
- * pr_info("Read MAC addr from EEPROM: %pM\n", mac_addr);
- * }
- *
- * This function pointer and context can now be set up in at24_platform_data.
