misc: eeprom: at24: clean up at24_bin_write()

2015-07-31T11:32:31Z

The change removes redundant sysfs binary file boundary check, since this task is already done on caller side in fs/sysfs/file.c Signed-off-by: Vladimir Zapolskiy Signed-off-by: Wolfram Sang

eeprom: at24: extend driver to allow writing via i2c_smbus_write_byte_data

2014-11-17T18:54:22Z

I have a at24 EEPROM connected via i2c bus provided by ISCH i2c bus driver. This bus driver does not support I2C_FUNC_SMBUS_WRITE_I2C_BLOCK and so I was looking for a way to be able to write the eeprom. This patch adds support for I2C_SMBUS_BYTE_DATA writing via i2c_smbus_write_byte_data. It is quite slow, but it works.

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 ...

misc/at24: avoid infinite loop on write()

2013-10-29T23:24:33Z

This change fixes a problem of infinite zero byte write() without an error status, if there is an attempt to write a file bigger than EEPROM size over sysfs interface. Signed-off-by: Vladimir Zapolskiy Cc: Wolfram Sang Cc: Greg Kroah-Hartman Signed-off-by: Greg Kroah-Hartman

misc: (at24) move header to linux/platform_data/

2013-09-30T04:02:34Z

This patch moves the at24.h header from include/linux/i2c to include/linux/platform_data and updates existing support accordingly. It also fixes the following checkpatch warning: WARNING: please, no space before tabs #436: FILE: include/linux/platform_data/at24.h:31: + * ^Iu8 *mac_addr = ethernet_pdata->mac_addr;$ Signed-off-by: Vivien Didelot Signed-off-by: Wolfram Sang

misc/at24: add more sanity checks for parameters

2010-12-24T09:14:17Z

Side-effects happen when passing 0 to either io_limit or page_size. Give an error in case of this misconfiguration. Signed-off-by: Wolfram Sang Signed-off-by: Grant Likely

misc/at24: parse device tree data

2010-12-24T09:13:36Z

Information about the pagesize and read-only-status may also come from the devicetree. Parse this data, too, and act accordingly. While we are here, change the initialization printout a bit. write_max is useful to know to detect performance bottlenecks, the rest is superfluous.
