Merge tag 'imx-weim-3.12' of git://git.linaro.org/people/shawnguo/linux-2.6 into next/soc

2013-08-23T18:37:18+00:00

From Shawn Guo:
This is a patch series that updates imx-weim bus driver to have it
support more i.MX SoCs.  Because there is no maintainer for
drivers/bus so far, I'm forwarding it through IMX tree for 3.12 merge
window.

bus: mvebu-mbus: Add devicetree binding

2013-08-06T14:12:37+00:00

Introduce the devicetree binding for the mvebu MBus driver
avaiable in the mvebu SoCs (Armada 370/XP, Kirkwood, Dove, ...).

This binding provides an accurate model of the SoC address space,
and allows to declare the address and size of the decoding windows the MBus
needs to access the peripherals, together with the target ID and attribute
for those windows.

The binding is composed of two required nodes: one for the MBus bus
and one for the MBus controller.

Merge tag 'drivers-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

2013-07-02T21:33:21+00:00

Pull ARM SoC driver specific changes from Arnd Bergmann:
 "These changes are all driver specific and cross over between arm-soc
  contents and some other subsystem, in these cases cpufreq, crypto,
  dma, pinctrl, mailbox and usb, and the subsystem owners agreed to have
  these changes merged through arm-soc.

  As we proceed to untangle the dependencies between platform code and
  driver code, the amount of changes in this category is fortunately
  shrinking, for 3.11 we have 16 branches here and 101 non-merge
  changesets, the majority of which are for the stedma40 dma engine
  driver used in the ux500 platform.  Cleaning up that code touches
  multiple subsystems, but gets rid of the dependency in the end.

  The mailbox code moved out from mach-omap2 to drivers/mailbox is an
  intermediate step and is still omap specific at the moment.  Patches
  exist to generalize the subsystem and add other drivers with the same
  API, but those did not make it for 3.11."

drivers: bus: add a new driver for WEIM

2013-06-17T08:04:28+00:00

The WEIM(Wireless External Interface Module) works like a bus.
You can attach many different devices on it, such as NOR, onenand.

In the case of i.MX6q-sabreauto, the NOR is connected to WEIM.

This patch also adds the devicetree binding document.
The driver only works when the devicetree is enabled.

ARM: dts: OMAP2+: Simplify NAND support

2013-05-16T16:21:19+00:00

Commit 8c8a777 (ARM: OMAP2+: Add function to read GPMC settings from
device-tree) added a device-tree property "gpmc,device-nand" to indicate
is the GPMC child device is NAND. This commit should have updated the
GPMC NAND documentation (Documentation/devicetree/bindings/mtd/gpmc-nand.txt)
to list the property "gpmc,device-nand" as a required property and also
updated the example. However, this property is redundant and not needed
because the GPMC child device node for NAND is called "nand". Therefore,
remove this property.

ARM: OMAP2+: Add additional GPMC timing parameters

2013-04-04T01:12:18+00:00

Some of the GPMC timings parameters are currently missing from the GPMC
device-tree binding. Add these parameters to the binding documentation
as well as code to read them. Also add either "-ps" or "-ns" suffix to
the GPMC timing properties to indicate whether the timing is in
picoseconds or nanoseconds.

The existing code in gpmc_read_timings_dt() is checking the value of
of_property_read_u32() and only is successful storing the value read
in the gpmc_timings structure. Checking the return value in this case
is not necessary and we can simply read the value, if present, and
store directly in the gpmc_timings structure. Therefore, simplify the
code by removing these checks.

The comment in the gpmc_read_timings_dt() function, "only for OMAP3430"
is also incorrect as it is applicable to all OMAP3+ devices. So correct
this too.

ARM: OMAP2+: Add function to read GPMC settings from device-tree

2013-04-01T19:53:45+00:00

Adds a function to read the various GPMC chip-select settings from
device-tree and store them in the gpmc_settings structure.

Update the GPMC device-tree binding documentation to describe these
options.

ARM: OMAP: gpmc: add DT bindings for GPMC timings and NAND

2013-01-15T22:50:15+00:00

This patch adds basic DT bindings for OMAP GPMC.

The actual peripherals are instantiated from child nodes within the GPMC
node, and the only type of device that is currently supported is NAND.

Code was added to parse the generic GPMC timing parameters and some
documentation with examples on how to use them.

Successfully tested on an AM33xx board.

2012-10-29T15:56:30+00:00

*reg* property for ocp2scp was previously obtained from ti,hwmods property.
But that is now explicitly added to the dt node.
Also updated the documentation with *reg* info.
