      i2c-rpx: Remove · 0a85e9a2
      由 Jean Delvare 提交于 
      This driver has been broken forever. It depends on i2c-algo-8xx which
has never been in the mainline kernel.

      i2c-i801: Use the internal 32-byte buffer on ICH4+ · 7edcb9ab
      由 Oleg Ryjkov 提交于 
      Add an ability to utilize the internal SRAM buffer on ICH4
and newer host controllers to speed up execution of block operations.

I've split the code so that it is more clear which block transaction is
performed.

First of all the host controller's type is identified. isich4 is set when
we think that the controller has the internal buffer. Then, before every
block transaction, if isich4 is set, we attempt to enable the E32B bit in
SMBAUXCTL register.

      i2c: Fix the i2c_smbus_read_i2c_block_data() prototype · 4b2643d7
      由 Jean Delvare 提交于 
      Let the drivers specify how many bytes they want to read with
i2c_smbus_read_i2c_block_data(). So far, the block count was
hard-coded to I2C_SMBUS_BLOCK_MAX (32), which did not make much sense.
Many driver authors complained about this before, and I believe it's
about time to fix it. Right now, authors have to do technically stupid
things, such as individual byte reads or full-fledged I2C messaging,
to work around the problem. We do not want to encourage that.

I even found that some bus drivers (e.g. i2c-amd8111) already
implemented I2C block read the "right" way, that is, they didn't
follow the old, broken standard. The fact that it was never noticed
before just shows how little i2c_smbus_read_i2c_block_data() was used,
which isn't that surprising given how broken its prototype was so far.

There are some obvious compatiblity considerations:
* This changes the i2c_smbus_read_i2c_block_data() prototype. Users
  outside the kernel tree will notice at compilation time, and will
  have to update their code.
* User-space has access to i2c_smbus_xfer() directly using i2c-dev, so
  the changed expectations would affect tools such as i2cdump. In order
  to preserve binary compatibility, we give I2C_SMBUS_I2C_BLOCK_DATA
  a new numeric value, and define I2C_SMBUS_I2C_BLOCK_BROKEN with the
  old numeric value. When i2c-dev receives a transaction with the
  old value, it can convert it to the new format on the fly.

      i2c: Delete outdated x1205 driver documentation · 890e0375

      The x1205 driver moved to the RTC subsystem and was significantly
modified since then, so just delete the outdated documentation.
