This patch implements a workaround for erratum 764369 affecting
Cortex-A9 MPCore with two or more processors (all current revisions).
Under certain timing circumstances, a data cache line maintenance
operation by MVA targeting an Inner Shareable memory region may fail to
proceed up to either the Point of Coherency or to the Point of
Unification of the system. This workaround adds a DSB instruction before
the relevant cache maintenance functions and sets a specific bit in the
diagnostic control register of the SCU.

This patch adds common DMA operations which are used for Samsung DMA
drivers. Currently there are two types of DMA driver for Samsung SoCs.
The one is S3C-DMA for S3C SoCs and the other is PL330-DMA for S5P SoCs.
This patch provides funcion pointers for common DMA operations to DMA
client driver like SPI and Audio. It makes DMA client drivers support
multi-platform.
In addition, this common DMA operations implement the shared actions
that are needed for DMA client driver. For example shared actions are
filter() function for dma_request_channel() and parameter passing for
device_prep_slave_sg().

The TNET variant of DaVinci compiles some code that it shares
with other DaVinci variants, however it has a V6 CPU rather than
an ARM926T, thus the hardcoded call to arm926_flush_kern_cache_all()
in sleep.S will obviously fail, and we need to build with the
v6_flush_kern_cache_all() call instead. This was triggered by
manually altering the DaVinci config to build the TNET version.

DA850/OMAP-L138 EMAC driver uses random mac address instead of
a fixed one because the mac address is not stuffed into EMAC
platform data.
This patch provides a function which reads the mac address
stored in SPI flash (registered as MTD device) and populates the
EMAC platform data. The function which reads the mac address is
registered as a callback which gets called upon addition of MTD
device.
NOTE: In case the MAC address stored in SPI flash is erased, follow
the instructions at [1] to restore it.
[1] http://processors.wiki.ti.com/index.php/GSG:_OMAP-L138_DVEVM_Additional_Procedures#Restoring_MAC_address_on_SPI_Flash
Modifications in v2:
Guarded registering the mtd_notifier only when MTD is enabled.
Earlier this was handled using mtd_has_partitions() call, but
this has been removed in Linux v3.0.
Modifications in v3:
a. Guarded da850_evm_m25p80_notify_add() function and
da850evm_spi_notifier structure with CONFIG_MTD macros.
b. Renamed da850_evm_register_mtd_user() function to
da850_evm_setup_mac_addr() and removed the struct mtd_notifier
argument to this function.
c. Passed the da850evm_spi_notifier structure to register_mtd_user()
function.
Modifications in v4:
Moved the da850_evm_setup_mac_addr() function within the first
CONFIG_MTD ifdef construct.

When ARCH_HAS_HOLES_MEMORYMODEL is selected, pfn_valid calls
memblock_is_memory to test validity of a pfn:
> memblock_is_memory(pfn << PAGE_SHIFT);
On LPAE systems this cuts off the top bits, as the shift occurs before
the value is promoted to a phys_addr_t.
This patch replaces the shift with a call to __pfn_to_phys (which casts
pfn to phys_addr_t before shifting), preventing the loss of significant
bits.

This patch removes support for the SGX interrupt source in
the sh7372 INTCS controller.
The SGX hardware block included in sh7372 is already hooked
up to the ARM Cortex-A8 core using the INTCA controller,
so SGX users are encouraged to make use of that interrupt
source instead.
Removing support for the SGX interrupt source in INTCS
simplifies the sh7372 power management code by allowing
us to assume that only INTCA needs to be powered on to
operate the SGX hardware.
If the INTCS interrupt source would be kept then the kernel
would be forced to deal with additional dependencies that does
not follow the regular power domain hiearachy. With this
patch in place we can safely power down INTCS while the
SGX is operating.

Commit c03f007a8b (OMAP: PM:
omap_device: add system PM methods for PM domain handling) mistakenly
used SET_SYSTEM_SLEEP_PM_OPS() when trying to configure custom methods
for the PM domains noirq methods. Fix that by setting only the
suspend_noirq and resume_noirq methods with custom versions.
Note that all other PM domain methods (including the "normal"
suspend/resume methods) are populated using USE_PLATFORM_PM_SLEEP_OPS,
which configures them all to the default subsystem (platform_bus)
methods.

Associate the HDMI clock together with LCDC1 on sh7372.
Without this patch Suspend-to-RAM hangs on the boards
AP4EVB and Mackerel. The code hangs in the LCDC driver
where the software is waiting forever for the hardware to
power down. By explicitly associating the HDMI clock with
LCDC1 we can make sure the HDMI clock is enabled using
Runtime PM whenever the driver is accessing the hardware.
This HDMI and LCDC1 dependency is documented in the sh7372
data sheet. Older kernels did work as expected but the
recently merged (3.1-rc)
794d78f drivers: sh: late disabling of clocks V2
introduced code to turn off clocks lacking software reference
which happens to include the HDMI clock that is needed by
LCDC1 to operate as expected.

While not obviously stated in the hardware docs, the onboard SP810's
"REFCLK" is connected to a 32.768KHz crystal, and this drives the
watchdog. Add a struct clk and corresponding lookup entry for it.

After commit 665d001338 ("OMAP2+: hwmod:
Follow the recommended PRCM module enable sequence"), device drivers
for OMAP IP blocks that do not use runtime PM can cause oopses or
kernel instability[1][2].
This is because those non-runtime PM drivers do not use the hwmod
code, which implements the correct IP block enable and disable
sequence.
Several options for dealing with this problem have been proposed:
1. Add a new field to the OMAP struct clk to mark clocks that are
currently used by non-runtime PM drivers. Modify the clock code to
use the old clockdomain sequence for these marked clocks. As
drivers are converted to use runtime PM, remove the annotation from
the clocks.
2. Similar to #1, but associate the flag with the struct omap_clk
instead.
3. Add IDLEST wait support to the OMAP4 clock code, similar to the way
it is implemented for OMAP2/3, and enable it in each struct clk
currently used by non-runtime PM drivers. As drivers are converted
to use runtime PM, remove the annotation from the clocks.
4. Do nothing; leave the problem to those responsible for the
unconverted drivers.
5. Re-enable clock-based clockdomain control in the OMAP4 clock code.
This would revert back to the behavior of Linux 3.0, simply with a
slightly longer module enable/disable latency.
Unfortunately, no approach seemed particularly good. Options 1
through 3 seemed unwise due to the following reasons:
A. The OMAP struct clks are intended primarily to describe hardware
clock nodes, and the intention is that no driver-specific data
should be stored there (applies to #1)
B. The resulting patch would have been quite large for the -rc series
(applies to #1, #2, #3)
C. The patch would have been a new, yet temporary hack; and similar fixes
have drawn negative comments in the recent past (see for example [3])
Option 4 is undesirable because commit
665d001338 ("OMAP2+: hwmod: Follow the
recommended PRCM module enable sequence") has resulted in a less
stable kernel; and kernel stability is more important than OMAP4 power
management.
Option 5 is the approach taken in this patch. This seemed to be the
least intrusive approach for 3.1-rc.
The approach in this patch was originally proposed by Ohad Ben-Cohen
<ohad@wizery.com>. I'm simply writing the commit message and passing
it along.

Program all powerdomain target state as ON; this is to prevent domains
from hitting low power states (if bootloader has target states set to
something other than ON) and potentially even losing context while PM
is not fully initialized, which can cause the system to crash. The PM
late init code can then program the desired target state for all the
power domains.

This patch fixes L2 Cache size calculations for L2C-210, L2C-310 and
PL310, by changing the L2X0_AUX_CTRL_WAY_SIZE_MASK from 2 bits to 3
bits.
The Auxiliary Control Register for L2C-210, L2C-310 and PL310 has 3bits
[19:17] for Way size, however the existing code only uses 2 bits to
get this value. This results in incorrect cachesize calculations.
It also results in performing operations on the whole cache when we
erroneously decide that the range is big enough (due to l2x0_size being
too small) and also prints incorrect cachesize.
