Nothing outside mach-tegra uses this file, so there's no need for it to
be in <mach/>.
Since uncompress.h and debug-macro.S remain in include/mach, they need
to include "../../irammap.h" becaue of this change. Both these usages
will be removed shortly, when Tegra's DEBUG_LL implementation is updated
not to pass information through IRAM.

Since uncompress.h and debug-macro.S remain in include/mach, they need
to include "../../iomap.h" becaue of this change. uncompress.h will soon
be deleted in later multi-platform/single-zImage patches. debug-macro.S
will need to continue to include this header using an explicit relative
path, to avoid duplicating the physical->virtual address mapping that
iomap.h dictates.

Remove includes of <mach/dma.h> from sound/soc; nothing from it is used.
Remove include of <mach/dma.h> from mach-tegra/apbio.c; since the DMA
transfers made by this file don't need flow-control with any peripheral,
there's no need to set any slave ID.
Once those changes are made, there are no remaining users of <mach/dma.h>
so remove it. Drivers should get this information from device tree. This
removal is necessary for single zImage.

We wish to empty arch/arm/mach-tegra/include/mach/ as much as possible

In https://bugzilla.kernel.org/show_bug.cgi?id=48981
Peter reported that /proc/bus/pci/??/??.? does not work for 3.6.
This is because the device configuration space registers are
not accessible if the corresponding parent bridge is suspended or
the device is put into D3cold state.
This is the same as /sys/bus/pci/devices/0000:??:??.?/config access
issue. So the function used to solve sysfs issue is used to solve
this issue.
This patch moves pci_config_pm_runtime_get()/_put() from pci/pci-sysfs.c
to pci/pci.c and makes them extern so they can be used by both the
sysfs and proc paths.

When using DEBUG_LL, the UART's (or other HW's) registers are mapped
into early page tables based on the results of assembly macro addruart.
Later, when the page tables are replaced, the same virtual address must
remain valid. Historically, this has been ensured by using defines from
<mach/iomap.h> in both the implementation of addruart, and the machine's
.map_io() function. However, with the move to single zImage, we wish to
remove <mach/iomap.h>. To enable this, the macro addruart may be used
when constructing the late page tables too; addruart is exposed as a
C function debug_ll_addr(), and used to set up the required mapping in
debug_ll_io_init(), which may called on an opt-in basis from a machine's
.map_io() function.

This patch starts using all the configuration infrastructure.
- generic GPIO library is forced now
- sysreg GPIOs are used as MMC CD and WP information sources;
thanks to this MMCI auxiliary data is not longer necessary
- DVI muxer and mode control is removed from non-DT V2P-CA9 code
as this is now handled by the vexpress-dvi driver
- clock generators control is removed as is being handled by the
common clock driver now
- the sysreg and sysctl control is now delegated to the
appropriate drivers and all related code was removed
- NOR Flash set_vpp function has been removed as the control
bit used does _not_ control its VPP line, but the #WP signal
instead (which is de facto unusable in case of Linux MTD
drivers); this also allowed the remove its DT auxiliary
data
The non-DT code defines only minimal required number of
the config devices. Device Trees are updated to make use
of all new features.

Add description of all functions provided by Versatile Express
motherboard and daughterboards configuration controllers and
clock dependencies between devices.
Signed-off-by: Pawel Moll <pawel.moll@arm.com>
|

This is a platform driver for Versatile Express' "system
register" block. It's a random collection of registers providing
the following functionality:
- low level platform functions like board ID access; in order to
use those, the driver must be initialized early, either statically
or based on the DT
- config bus bridge via "system control" interface; as the response
from the controller does not generate interrupt (yet), the status
register is periodically polled using a timer
- pseudo GPIO lines providing MMC card status and Flash WP#
signal control
- LED interface for a set of 8 LEDs on the motherboard, with
"heartbeat", "mmc0" and "cpu0" to "cpu5" as default triggers

Versatile Express platform has an elaborated configuration system,
consisting of microcontrollers residing on the mother- and
daughterboards known as Motherboard/Daughterboard Configuration
Controller (MCC and DCC). The controllers are responsible for
the platform initialization (reset generation, flash programming,
FPGA bitfiles loading etc.) but also control clock generators,
voltage regulators, gather environmental data like temperature,
power consumption etc. Even the video output switch (FPGA) is
controlled that way.
Those devices are _not_ visible in the main address space and
the usual communication channel uses some kind of a bridge in
the peripheral block sending commands (requests) to the
controllers and receiving responses. It can take up to
500 microseconds for a transaction to be completed, therefore
it is important to provide a non-blocking interface to it.
This patch adds an abstraction of this infrastructure. Bridge
drivers can register themselves with the framework. Then,
a driver of a device can request an abstract "function" - the
request will be redirected to a bridge referred by thedd
"arm,vexpress,config-bridge" property of the device tree node.

While copying the argument structures in HYPERVISOR_event_channel_op()
and HYPERVISOR_physdev_op() into the local variable is sufficiently
safe even if the actual structure is smaller than the container one,
copying back eventual output values the same way isn't: This may
collide with on-stack variables (particularly "rc") which may change
between the first and second memcpy() (i.e. the second memcpy() could
discard that change).
Move the fallback code into out-of-line functions, and handle all of
the operations known by this old a hypervisor individually: Some don't
require copying back anything at all, and for the rest use the
individual argument structures' sizes rather than the container's.
