The DM6467 and DM6467T EVMs use different reference clock
frequencies. This difference is currently supported by having
the SoC code call a public board routine which sets up the reference
clock frequency. This does not scale as more boards are added.
Instead, use the clk_set_rate() API to setup the reference clock
frequency to a different value from the board file.

The ux500 machine was actually defining platform data for the
staging driver ste_rmi4, which is not OK. Let us instead define
some __weak platform data in the machine so that the staging
driver can override it at compile-time and we can thus have the
driver self-contained in staging.

Consumers of the table pointers in struct efi check for
EFI_INVALID_TABLE_ADDR to determine validity, hence these
pointers should all be pre-initialized to this value (rather
than zero).
Noticed by the discrepancy between efivars' systab sysfs entry
showing all tables (and their pointers) despite the code
intending to only display the valid ones. No other bad effects
known, but having the various table parsing routines bogusly
access physical address zero is certainly not very desirable
(even though they're unlikely to find anything useful there).

armpmu_enable can be called in situations where no events are present
(for example, from the event rotation tick after a profiled task has

leave it active inevitably without any events being monitored.
This patch adds a simple check to the enabling code so that we avoid

The vaux2 (VCSI) regulator is left on by the bootloader
in rx-51. Since there the product has shipped and there
won't be any bootloader updates to fix this issue, we
need to define all the regulators and declare full
constraints for the regulator FW. This will allow the
regulator FW to disable unused regulators.
Also this helps in adding more fine grain regulator
support for rx-51 in the future.

* 'at91/fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/linux-2.6-arm-soc:
AT91: Change nand buswidth logic to match hardware default configuration
at91: Use "pclk" as con_id on at91cap9 and at91rm9200
at91: fix udc, ehci and mmc clock device name for cap9/9g45/9rl
atmel_serial: fix internal port num
at91: fix at91_set_serial_console: use platform device id
The recently modified nand buswitth configuration is not aligned with
board reality: the double footprint on boards is always populated with 8bits
buswidth nand flashes.
So we have to consider that without particular configuration the 8bits
buswidth is selected by default.
Moreover, the previous logic was always using !board_have_nand_8bit(), we
change it to a simpler: board_have_nand_16bit().

can be accessed by I2C and PDM interface.
