* Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linusLinus Torvalds2012-08-0114-72/+108
|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Pull MIPS updates from Ralf Baechle: "The lion share of this pull request are fixes for clk-related breakage caused by other changes during this merge window. For some platforms the fix was as simple as selecting HAVE_CLK, for others like the Loongson 2 significant restructuring was required. The remainder are changes required to get the Lantiq code to work again." * 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus: MIPS: Loongson 2: Sort out clock managment.

| | | | | | | | | | | | | | For unexplainable reasons the Loongson 2 clock API was implemented in a module so fixing this involved shifting large amounts of code around. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

If the counters are not initialized, the corresponding pin (typically connected to the power button) has to be asserted for two seconds before the device wakes up. Most users expect a shorter wakeup time. I took the timing values of 100 ms and 60 ms from BouKiCHi's patch for the Dingoo A320 kernel.

To this end several properties that are not part of the declared bindings are added to aid in trimming off unwanted nodes. Since the device tree and the code that trims it are bound into the kernel binary, these 'marker' properties never escape into the wild, and are purely an implementation detail of the kernel early boot process. This is done for backwards compatibility with existing boards (identified by a board type enumeration value by their bootloaders). New boards will always pass a device tree from the bootloader, the built-in trees are ignored in this case.
