This makes the topology clearer.

2014-11-18i2c: mux: create symlink to actual mux deviceWolfram Sang1-0/+4
The current implementation creates muxed i2c-<n> busses as immediate children of their i2c-<n> parent bus. In case of multiple muxes on one bus, it is impossible to determine which muxed bus comes from which mux. It could be argued that the parent device should be changed from the parent adapter to the mux device. This has pros and cons. To improve the topology, simply add a "mux_device" symlink pointing to the actual muxing device, so we can distinguish muxed busses. Doing it this way, we don't break the ABI.

2014-11-17i2c: core: Fix probing of i2c slaves without interruptsGeert Uytterhoeven1-1/+3
Since commit 2fd36c55264926e2 ("i2c: core: Map OF IRQ at probe time"), i2c slaves without interrupts (e.g. da9210 and at24 on r8a7791/koelsch) fail to probe: at24: probe of 2-0050 failed with error -22 da9210: probe of 6-0068 failed with error -22 This happens because the call to of_irq_get() in i2c_device_probe() returns -EINVAL. If a device node does not have an "interrupts" property, of_irq_parse_one() fails. Unlike irq_of_parse_and_map(), of_irq_get() does not ignore errors from of_irq_parse_one(), but forwards them. Make i2c_device_probe() ignore all errors but -EPROBE_DEFER to fix this, just like platform_get_irq() and platform_get_irq_byname() already do.

2014-11-17i2c: xiic: Fix big-endian register accessThomas Gessler1-5/+53
The driver tried to access device registers with the (little-endian) iowrite/ioread functions. While this worked on little-endian machines (e.g. Microblaze with AXI bus), it made the driver unusable on big-endian machines (e.g. PPC405 with PLB). During the probe function, the driver tried to write a 32-bit reset mask into the reset register. This caused an error interrupt on big-endian systems, because the device detected an invalid (byte-swapped) reset mask. The result was an Oops. The patch implements an endianness detection similar to the one used in other Xilinx drivers like drivers/spi/spi-xilinx.c. It was tested on a PPC405/PLB system.

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.

2014-11-10i2c: davinci: don't use interruptible completionMike Looijmans1-3/+1
When a signal is caught while the i2c-davinci bus driver is transferring, the driver just "abandons" the transfer and leaves the controller to fend for itself. The next I2C transaction will find the controller in an undefined state and often results in a stream of "initiating i2c bus recovery" messages until the controller arrives in a defined state. This behaviour also sends out "half" or possibly even mixed messages to I2C client devices which may put them in an undesired state as well. So, let's get simply uninterruptible.

2014-11-10i2c: core: Map OF IRQ at probe timeLaurent Pinchart1-2/+9
I2C clients instantiated from OF get their IRQ mapped at device registration time. This leads to the IRQ being silently ignored if the related irqchip hasn't been proved yet. Fix this by moving IRQ mapping at probe time using of_get_irq(). The function operates as irq_of_parse_and_map() but additionally returns -EPROBE_DEFER if the irqchip isn't available, allowing us to defer I2C client probing.
