Mark Brown f4e8db31a8 i2c: Encourage move to dev_pm_ops by warning on use of legacy methods
Since the PM core wishes to transition away from the legacy suspend
and resume methods and since removing them makes using PM core features
like runtime PM much easier start warning when a driver is registered
using the legacy methods.

Mark Brown d529de2994 i2c: Factor out runtime suspend checks from PM operations
When devices use dev_pm_ops the I2C API is implementing standard functionality
for integration with runtime PM and for checking for the presence of a per
device op. The PM core provides pm_generic_ functions implementing this
behaviour - use them to reduce coupling with future PM updates.

Andres Salomon de8255ccd2 i2c: Convert SCx200 driver from using raw PCI to platform device
The SCx200 ACB driver supports ISA hardware as well as PCI.  The PCI
hardware is CS5535/CS5536 based, and the device that it grabs is handled by
the cs5535-mfd driver. This converts the SCx200 driver to use a
platform_driver rather than the previous PCI hackery.

The driver used to manually track the iface list (via linked list); now it
only does this for ISA devices.  PCI ifaces are handled through standard
driver model lists.

It's unclear what happens in case of errors in the old ISA code; rather than
pretending the code actually cares, I've dropped the (implicit) ignorance
of return values and marked it with a comment.

Michael Hennerich 74f56c4ad4 i2c-bfin-twi: move setup to the earlier subsys initcall
Some systems using this bus sometimes have very basic devices such as
regulators on the bus, so the I2C bus master needs to be loaded early.
This also matches the behavior of many other I2C bus master drivers.
Therefore initialize via subsys_initcall().

Jean Delvare af5a60baae i2c-algo-bit: Complain about masters which can't read SCL
The I2C specification explicitly describes both SDA and SCL as
bidirectional lines. An I2C master with a read-only SCL is thus not
compliant. If a slow slave stretches the clock, errors will happen,
so the bus can't be considered as reliable.

hardware MUX sitting on a master bus and controlled through gpio pins.

E.G. something like:

  ----------              ----------  Bus segment 1   - - - - -
 |          | SCL/SDA    |          |-------------- |           |

 |          |            |          | Bus segment 2 |           |
 |  Linux   | GPIO 1..N  |   MUX    |---------------   Devices
 |          |------------|          |               |           |

SCL/SDA of the master I2C bus is multiplexed to bus segment 1..M
according to the settings of the GPIO pins 1..N.

Rodolfo Giometti eda6bee6c7 i2c-mv64xxx: send repeated START between messages in xfer
As stated into file include/linux/i2c.h we must send a repeated START
between messages in the same xfer groupset:

 * Except when I2C "protocol mangling" is used, all I2C adapters implement
 * the standard rules for I2C transactions.  Each transaction begins with a
 * START.  That is followed by the slave address, and a bit encoding read
 * versus write.  Then follow all the data bytes, possibly including a byte
 * with SMBus PEC.  The transfer terminates with a NAK, or when all those
 * bytes have been transferred and ACKed.  If this is the last message in a
 * group, it is followed by a STOP.  Otherwise it is followed by the next
 * @i2c_msg transaction segment, beginning with a (repeated) START.

This puts some documentation for the device tree configuration at the head
of the driver file.  Hopefully this can get moved to a common area for this
type of documentation at a later date; unfortunately, there isn't really
such a place in the kernel tree at this time.

Furthermore, the regstep and clock-frequency parameters are really bus
parameters and should probably be passed to the driver in a better way.

Alan Cox aa62f85d0c i2c-intel-mid: support for Moorestown and Medfield platform
(Updated to address Ben's comments. With regard to the message segment
 restriction it's not something we hit on the actual platform so while
 I will investigate that further I don't think its a blocker to submission.
 At worst its a spot over-restrictive)

From: Wen Wang <wen.w.wang@intel.com>

Initial release of the driver. Updated and verified on hardware.

Cleaned up as follows

Alan Cox:
   Squash down the switches into tables, and use the PCI ident field. We
   could perhaps take this further and put the platform and port number into
   this.
   uint32t -> u32
   bracketing of case statements
   spacing and '!' usage
   Check the speed (which is now 0/1/2) is valid and ignore otherwise.
   Fix remaining problems/suggestions from Jean's review
   Fix items from Ben's review

Arjan van de Ven:
   Initial power management hooks

Yong Wang <youg.y.wang@intel.com>:
   Shared IRQ support

Wen Wang <wen.w.wang@intel.com>:
   D3 support
   Fixes for OCT test runs
   Interrupt optimisations

Hong Liu <hong.liu@intel.com>
   The runtime PM code is working on the wrong device (i2c_adapter->dev).
   The correct one should be pci_dev->dev. This breaks attached i2c
   slave devices with runtime PM enabled. Slave device needs to runtime
   resume parent device before runtime resuming itself, but we always get
   error since we don't have pm_runtime callback for i2c_adapter->dev.

Bin Yang <bin.yang@intel.com>:
   Update speed table

Saadi Maalem <saadi.maalem@intel.com>:
   Clear all interrupts in the hardware init

Celine Chotard <celinex.chotard@intel.com>:
   Correct ordering of clear/disable of IRQs
