2013-08-23i2c: move ACPI helpers into the coreMika Westerberg
This follows what has already been done for the DeviceTree helpers. Move the ACPI helpers from drivers/acpi/acpi_i2c.c to the I2C core and update documentation accordingly. This also solves a problem reported by Jerry Snitselaar that we can't build the ACPI I2C helpers as a module. Signed-off-by: Mika Westerberg <mika.westerberg@linux.intel.com> Acked-by: Rafael J.

2013-08-23i2c: move OF helpers into the coreWolfram Sang
I2C of helpers used to live in of_i2c.c but experience (from SPI) shows that it is much cleaner to have this in the core. This also removes a circular dependency between the helpers and the core, and so we can finally register child nodes in the core instead of doing this manually in each driver. So, fix the drivers and documentation, too. Signed-off-by: Wolfram Sang <wsa@the-dreams.de>
2013-08-23i2c: mv64xxx: Fix timing issue on Armada XP (errata FE-8471889)Gregory CLEMENT
All the Armada XP (mv78230, mv78260 and mv78460) have a silicon issue in the I2C controller which violate the i2c repeated start timing. The I2C standard requires a minimum of 4.7us for the repeated start condition whereas the I2C controller of the Armada XP this time is 2.9us. So this patch adds a 5us delay for the start case only if the the compatible i2c-mv78230 is set.

2013-08-19i2c: omap: query STP always when NACK is receivedGrygorii Strashko
According to I2C specification the NACK should be handled as folowing: "When SDA remains HIGH during this ninth clock pulse, this is defined as the Not Acknowledge signal. The master can then gene rate either a STOP condition to abort the transfer, or a repeated START condition to start a new transfer." [http://www.nxp.com/documents/user_manual/UM10204.pdf] The same is recomened by TI I2C wiki: http://processors.wiki.ti.com/index.php/I2C_Tips Currently, the OMAP I2C driver interrupts I2C trunsfer in case of NACK, but It queries Stop condition OMAP_I2C_CON_REG.STP=1 only if NACK has been received during the last message transmitting/recieving. This may lead to stuck Bus in "Bus Busy" until I2C IP reset (idle/enable). Hence, fix it by querying Stop condition (STP) always when NACK is received.

2013-08-16i2c: mxs: fix broken timing calculationLothar Waßmann
The timing calculation is rather bogus and gives extremely wrong results for higher frequencies (on an i.MX28). E.g. instead of 400 kHz I measured 770 kHz. Implement a calculation that adheres to the I2C spec and gives exact results for I2C frequencies from 12.56 kHz to 960 kHz. Also the bus_free and leadin parameters are programmed according to the I2C spec for standard and fast mode. This was tested on a Ka-Ro TX28 module with a DS1339, TSC2007, PCA9554 and SGTL5000 client.

2013-08-07i2c: mpc: Define unique I2C adapter namesGuenter Roeck
The I2C adapters on Freescale MPC107/824x/85xx/512x/52xx/83xx/86xx all have the same name "MPC adapter". Since I2C adapter numbers can change across reboots and even after loading/unloading an I2C bus master driver, adapter names have to be used to identify adapters and thus should be unique and well defined. Since this is not the case with this driver, it is difficult if not impossible to identify a specific adapter from user space on affected platforms. To remedy the problem, use the adapter memory address as part of the adapter name. With this patch, adapter names are: On P2020: MPC adapter at 0xfff703000 MPC adapter at 0xfff703100 On P5040: MPC adapter at 0xffe118000 MPC adapter at 0xffe118100 MPC adapter at 0xffe119000 MPC adapter at 0xffe119100 Signed-off-by: Guenter Roeck <linux@roeck-us.net> Acked-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Wolfram Sang <wsa@the-dreams.de>
