• a56ec9835   x86: dt: Correct local apic documentation in device tree bindings ... Browse Code »

  Until "x86: dt: Cleanup local apic setup" we read the local apic
  address from the MSR and ignored the entry in DT. Reflect this change
  in the documentation.

• df2634f43   x86: dtb: Add a device tree for CE4100 ... Browse Code »

  History:
  v1..v2:
  - dropped device_type except for cpu & pci. I have the compatible string
  for pci so I can drop the device_type once it is possible
  - I lowercased all compatible types. I will need to resend some patches
  which have upper case intel
  - The cpu had the same compatible string as the soc node. So I added to
  the soc node -immr for internel memory mapped registers.
  - I added generic names for all parts.
  - I reworked the i2c bars matching the way you suggested. I added a
  compatible node for the PCI device which only the PCI ids in its
  compatible string. The bars (each represents a complete i2c
  controller) have a "intel,ce4100-i2c-controller" compatible node. It
  is not used by the driver.
  The driver is probed via PCI ids (by the pci subsystem not OF) and
  matches the bar address against the ressource in the child node. Once
  there is a hit the node is attached.
  - The SPI driver is also probed via pci. However I also attached a
  compatible property based on PCI ids

  v2..v3:
  - intel,ce4100-immr become intel,ce4100-cp. cp stands for core
  peripherals. The Atom data sheet talks here about ACPI devices. Since
  we don't have ACPI this does not apply here.
  - The interrupt map is gone. There are now plenty of device nodes.
  - The "unit address string" got fixed, it uses not DD,V format.

  v3..v4:
  - added descriptions for compatible nodes introduced here:
  - intel,ce4100-ioapic
  - intel,ce4100-lapic
  - intel,ce4100-hpet
  - intel,ce4100
  - intel,ce4100-cp
  - intel,ce4100-pci
  - added a description about I2C controller magic.
  - Added gpio-controller and gpio-cells property to gpio devices. Those
  properties are not (yet) used.
