      [POWERPC] Add of_register_i2c_devices() · d13ae862
      由 Guennadi Liakhovetski 提交于 
      Scan the device tree for i2c devices, check their "compatible" property
against a hard-coded table, and, if found, register with i2c boardinfo.
This provides the infrastructure needed to find i2c devices in the
device tree and register them with the i2c subsystem.

This and the following commit let the linkstation work with the new i2c
API and thus fix a regression.

      [POWERPC] MPIC protected sources · 7fd72186
      由 Benjamin Herrenschmidt 提交于 
      Some HW platforms, such as the new cell blades, requires some MPIC sources
to be left alone by the operating system. This implements support for
a "protected-sources" property in the mpic controller node containing a list
of source numbers to be protected against operating system interference.

For those interested in the gory details, the MPIC on the southbridge of
those blades has some of the processor outputs routed to the cell, and
at least one routed as a GPIO to the service processor. It will be used
in the GA product for routing some of the southbridge error interrupts
to the service processor which implements some of the RAS stuff, such
as checkstopping when fatal errors occurs before they can propagate.

      [CELL] driver for DDR2 memory on AXON · dbdf04c4
      由 Maxim Shchetynin 提交于 
      The Axon bridge chip used on new Cell/B.E. based blade servers
comes with a DDR2 memory controller that can be used to
attach cheap memory modules, as opposed to the high-speed
XDR memory that is used by the CPU itself.

Since the memory controller does not participate in the
cache coherency protocol, we can not use the memory direcly
for Linux applications, but by providing a block device
it can be used for swap space, temporary file storage and
through the use of the direct_access block device operation
for mapping into user addresses, when it is mounted with
an appropriate file system.

      [CELL] pmi: remove support for mutiple devices. · 813f9072
      由 Christian Krafft 提交于 
      The pmi driver got simplified by removing support for multiple devices.
As there is no more than one pmi device per maschine, there is no need to
specify the device for listening and sending messages.

This way the caller (cbe_cpufreq) doesn't need to scan the device tree.
When registering the handler on a board without a pmi
interface, pmi.c will just return -ENODEV.

The patch that fixed the breakage of cell_defconfig has been
broken out of the earlier version of this patch. So this is
the version that applies cleanly on top of it.

      Fix RGMII-ID handling in gianfar · 7132ab7f
      由 Andy Fleming 提交于 
      The TSEC/eTSEC can detect the interface to the PHY automatically,
but it isn't able to detect whether the RGMII connection needs internal
delay.  So we need to detect that change in the device tree, propagate
it to the platform data, and then check it if we're in RGMII.  This fixes
a bug on the 8641D HPCN board where the Vitesse PHY doesn't use the delay
for RGMII.
