      NTB: Add IDT 89HPESxNTx PCIe-switches support · bf2a952d
      Serge Semin authored 
      
IDT 89HPESxNTx device series is PCIe-switches, which support
Non-Transparent bridging between domains connected to the device ports.
Since new NTB API exposes multi-port interface and messaging API, the
IDT NT-functions can be now supported in the kernel. This driver adds
the following functionality:
1) Multi-port NTB API to have information of possible NT-functions
activated in compliance with available device ports.
2) Memory windows of direct and look up table based address translation
with all possible combinations of BARs setup.
3) Traditional doorbell NTB API.
4) One-on-one messaging NTB API.

There are some IDT PCIe-switch setups, which must be done before any of
the NTB peers started. It can be performed either by system BIOS via
IDT SMBus-slave interface or by pre-initialized IDT PCIe-switch EEPROM:
1) NT-functions of corresponding ports must be activated using
SWPARTxCTL and SWPORTxCTL registers.
2) BAR0 must be configured to expose NT-function configuration
registers map.
3) The rest of the BARs must have at least one memory window
configured, otherwise the driver will just return an error.
Temperature sensor of IDT PCIe-switches can be also optionally
activated by BIOS or EEPROM.
(See IDT documentations for details of how the pre-initialization can
be done)

      MAINTAINERS: Update ocrdma module status · 2c15b73a
      Selvin Xavier authored 
      
Since ocrdma driver is not going to be updated with any
new development activity, except for critical bug fixes
reported by partners or customers, changing the module status
to "Odd Fixes". Also, updating the web page info and the
maintainers email addresses.

      regulator: arizona-micsupp: Move pdata into a separate structure · 22161f3e
      Richard Fitzgerald authored 
      
In preparation for sharing this driver with Madera, move the pdata
for the micsupp regulator out of struct arizona_pdata into a dedicated
pdata struct for this driver. As a result the code in
arizona_micsupp_of_get_pdata() can be made independent of struct arizona.

This patch also updates the definition of struct arizona_pdata and
the use of this pdata in mach-crag6410-module.c

      mtd: nand: Cleanup/rework the atmel_nand driver · f88fc122
      Boris Brezillon authored 
      
This is a complete rewrite of the driver whose main purpose is to
support the new DT representation where the NAND controller node is now
really visible in the DT and appears under the EBI bus. With this new
representation, we can add other devices under the EBI bus without
risking pinmuxing conflicts (the NAND controller is under the EBI
bus logic and as such, share some of its pins with other devices
connected on this bus).

Even though the goal of this rework was not necessarily to add new
features, the new driver has been designed with this in mind. With a
clearer separation between the different blocks and different IP
revisions, adding new functionalities should be easier (we already
have plans to support SMC timing configuration so that we no longer
have to rely on the configuration done by the bootloader/bootstrap).

Also note that we no longer have a custom ->cmdfunc() implementation,
which means we can now benefit from new features added in the core
implementation for free (support for new NAND operations for example).

The last thing that we gain with this rework is support for multi-chips
and multi-dies chips, thanks to the clean NAND controller <-> NAND
devices representation.

During this transition we also dropped support for AVR32 SoCs which
should soon disappear from mainline (removal of the AVR32 arch is
planned for 4.12).

This new driver has been tested on several platforms (at91sam9261,
at91sam9g45, at91sam9x5, sama5d3 and sama5d4) to make sure it did not
introduce regressions, and it's worth mentioning that old bindings are
still supported (which partly explain the positive diffstat).
