1b0b323c70 omap3: nand: configurable transfer type per board
nand transfer type (sDMA, Polled, prefetch) can be select from board file,
enabling all transfer type in driver, by default.

this helps in multi-omap build and to select different transfer type for
different board.

1a5d81905a OMAP: devices: Modify McSPI device to adapt to hwmod framework
Cleans up all base address definitions for omap_mcspi
and adapts the device registration and driver to hwmod framework.
Changes involves:
1) Removing all base address macro defines.
2) Using omap-device layer to register device and utilizing data from
   hwmod data file for base address, dma channel number, Irq_number,
   device attribute(number of chipselect).
3) Appending base address with pdata reg_offset for omap4 boards.
   For omap4 all regs used in driver deviate with reg_offset_macros
   defined with an value of 0x100. So pass this offset through pdata
   and append the same to base address retrieved from hwmod data file
   and we are not mapping *_HL_* regs which are not used in driver.

Although only OMAP4 supports the hardware spinlock module (for now),

5844c4ead2 OMAP4: hwmod data: Add USBOTG
OMAP4 hwmod data structures are populated with base address, L3 and L4
interface clocks, IRQs and sysconfig register details.

As per OMAP USBOTG specification, need to configure the USBOTG
to smart idle/standby or no idle/standby during data transfer and
force idle/standby when not in use to support retention and offmode.
By setting HWMOD_SWSUP_SIDLE and HWMOD_SWSUP_MSTANDBY flags,framework
will take care of configuring to no idle/standby when module is enabled
and force idle/standby when idled.

In the case of the DSS, both L3 direct path and L4 CFG path can be

the two address spaces.

35d1a66a9c OMAP4: hwmod data: Add timer
Add the data for the 11 timers IPs.
OMAP4 contains two differents IP variants for the timers:
- 8 x regular timer (3, 4, 5, 6, 7, 8, 9 & 11)
- 3 x 1ms timer (1, 2 & 10)

The regular timers registers programming model was changed due to the
adaptation to the new IP interface. Unfortunately the 1ms version
still use the previous programming model. The driver will have
to take care of theses differences.

Please note that the capability and the partitioning is also
different depending of the instance.
- timer 1 is inside the wakeup domain
- timers 5, 6, 7 & 8 are inside in the ABE (audio backend)
- timers 2, 3, 4, 9, 10 & 11 are inside the PER power domain

The timer was previously named gptimerX or dmtimerX, it is
now simply named timerX.

The approach taken in this patch is to add TI816X as part of OMAP3 variant where
the cpu class is considered as OMAP34XX and the type is TI816X. This means, both
cpu_is_omap34xx() and cpu_is_ti816x() checks return success on TI816X.

support for TI816X build.

All callers of these functions live in .init.text, so these can go there,
too.  There they must not be exported anymore, this is no problem though,
as all callers are always built-in.

These are only called from omap_nokia770_init which is in .init.text, too.

15490ef8ff ARM: Avoid building unsafe kernels on OMAP2 and MX3
OMAP2 (armv6) and MX3 turn off support for the V6K instructions, which
when they include support for SMP kernels means that the resulting
kernel is unsafe on SMP and can result in corrupted filesystems as we
end up using unsafe bitops.

Re-enable the use of V6K instructions on such kernels, and let such
kernels running on V6 CPUs eat undefined instruction faults which will
be much safer than filesystem corruption.  Next merge window we can fix
this properly (as it requires a much bigger set of changes.)
