2c757fd5d1 arm-soc: cleanups, part 2
More cleanups, continuing an earlier set with omap and samsung specific
 cleanups. These could not go into the first set because they have
 dependencies on various other series that in turn depend on the first
 cleanups.

Merge tag 'cleanup2' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull arm-soc cleanups (part 2) from Olof Johansson:
 "More cleanups, continuing an earlier set with omap and samsung
  specific cleanups.  These could not go into the first set because they
  have dependencies on various other series that in turn depend on the
  first cleanups."

Fixed up conflicts in arch/arm/plat-omap/counter_32k.c due to commit
bd0493eaaf: "move read_{boot,persistent}_clock to the architecture
level" that changed how the persistent clocks were handled.  And trivial
conflicts in arch/arm/mach-omap1/common.h due to just independent
changes close to each other.

08ca7444f5 ARM: OMAP: Revert "ARM: OMAP: ctrl: Fix CONTROL_DSIPHY register fields"
This reverts commit 46f8c3c7e9.

The commit above swapped the DSI1_PPID and DSI2_PPID register fields in
CONTROL_DSIPHY to be in sync with the newer public OMAP TRMs(after version V).

With this commit, contention errors were reported on DSI lanes some OMAP4 SDPs.
After probing the DSI lanes on OMAP4 SDP, it was seen that setting bits in the
DSI2_PPID field was pulling up voltage on DSI1 lanes, and DSI1_PPID field was
pulling up voltage on DSI2 lanes.

This proves that the current version of OMAP4 TRM is incorrect, swap the
position of register fields according to the older TRM versions as they were
correct.

This patch updates existing macros, functions used for TI816X, to enable
addition of other SoCs belonging to TI81XX family (e.g., TI814X).

The approach taken is to use TI81XX/ti81xx for code/data going to be common
across all TI81XX devices.

cpu_is_ti81xx() is introduced to handle code common across TI81XX devices.

In addition, ti8168_evm_map_io() is now replaced with ti81xx_map_io() and moved
in mach-omap2/common.c as same will be used for TI814X and is not board
specific.

137d105d50 ARM: OMAP4: Fix errata i688 with MPU interconnect barriers.
On OMAP4 SOC, intecronnects has many write buffers in the async bridges
and they need to be drained before CPU enters into standby state.

Patch 'OMAP4: PM: Add CPUX OFF mode support' added CPU PM support
but OMAP errata i688 (Async Bridge Corruption) needs to be taken
care to avoid issues like system freeze, CPU deadlocks, random
crashes with register accesses, synchronisation loss on initiators
operating on both interconnect port simultaneously.

As per the errata, if a data is stalled inside asynchronous bridge
because of back pressure, it may be accepted multiple times, creating
pointer misalignment that will corrupt next transfers on that data
path until next reset of the system (No recovery procedure once
the issue is hit, the path remains consistently broken).
Async bridge can be found on path between MPU to EMIF and
MPU to L3 interconnect. This situation can happen only when the
idle is initiated by a Master Request Disconnection (which is
trigged by software when executing WFI on CPU).

The work-around for this errata needs all the initiators
connected through async bridge must ensure that data path
is properly drained before issuing WFI. This condition will be
met if one Strongly ordered access is performed to the
target right before executing the WFI. In MPU case, L3 T2ASYNC
FIFO and DDR T2ASYNC FIFO needs to be drained. IO barrier ensure
that there is no synchronisation loss on initiators operating
on both interconnect port simultaneously.

Thanks to Russell for a tip to conver assembly function to
C fuction there by reducing 40 odd lines of code from the patch.

fcf6efa3ff ARM: OMAP4: PM: Add WakeupGen module as OMAP gic_arch_extn
OMAP WakeupGen is the interrupt controller extension used along
with ARM GIC to wake the CPU out from low power states on
external interrupts.

The WakeupGen unit is responsible for generating the wakeup event
from the incoming interrupts and enable bits. It is implemented
in the MPU always ON power domain. During normal operation,
WakeupGen delivers the external interrupts directly to the GIC.

WakeupGen specification has one restriction as per Veyron version 1.6.
It is SW responsibility to program interrupt enabling/disabling
coherently in the GIC and in the WakeupGen enable registers. That is, a
given interrupt for a given CPU is either enable at both GIC and WakeupGen,
or disable at both, but no mix. That's the reason the WakeupGen is
implemented as an extension of GIC.

PPI handling is a bit of an odd beast. It uses its own low level

Instead, switch the low handling to the normal SPI handling code.
PPIs are handled by the handle_percpu_devid_irq flow.

This also allows the removal of some duplicated code.

fa808a1ba5 ARM: mach-omap2: clean up debug-macro.S
This achieves two goals:

1) Get rid of omap_uart_v2p() and omap_uart_p2v() which were the last users
   of PLAT_PHYS_OFFSET.

2) Remove the probing of the M bit in the CP15 control reg and make
   the access to the .data variables completely position independent.

There is a catch though: the busyuart macro needs to know where the LSR
register is which might be at a different offset depending on the hardware.
Given that this macro is given only two registers and that one of them
must be preserved, the trick is to always pass the LSR register address
around, and deduce the base address for the THR register by masking out
the LSR offset in senduart instead.

43b3e18982 ARM: 6860/1: OMAP4: Move the privately used SMP boot functions to OMAP specific header.
Header files in arch/arm/*/include/mach included from
arch/arm/include/asm/*.h are there to provide necessary definitions for
either the rest of the kernel or the ARM specific parts.  They shouldn't
be polluted with *any* platform private stuff which is not absolutely
necessary to satisfy the rest of the kernel.

Hence move the OMAP specific SMP boot functions to different header
instead of keeping them in 'plat/smp.h' which gets included indirectly
by linux/smp.h

The patch is outcome of the discussion in below thread:

For CONFIG_THUMB2_KERNEL, the existing definition of do_wfi() will
insert invalid code into the instruction stream.

Any assembler which can assemble Thumb-2 is guaranteed to accept
the "wfi" mnemonic, so for the Thumb-2 case, just use the mnemonic.

The ARM case is left as-is.

9f9605c2ed omap2+: Fix unused variable warning for omap_irq_base
Commit 5d190c4010
(omap2+: Initialize omap_irq_base for entry-macro.S from
platform code) simplified the handling of omap_irq_base
for multi-omap builds. However, this patch also introduced
a build warning for !MULTI_OMAP2 builds:

arch/arm/mach-omap2/io.c: In function 'omap_irq_base_init':
arch/arm/mach-omap2/io.c:322: warning: unused variable 'omap_irq_base'

Fix this by removing the ifdef. Also simplify things further
by moving omap_irq_base out of entry-macro.S.
