IO Resources are always expressed in the kernel's view, so they are in
the range from 0 to IO_SPACE_LIMIT. The idea is that you can have multiple
buses that each have their own address space start at 0, but can put
them into the kernel address space at a different address.
Each device on any bus can still use I/O addresses starting at zero,
and you could have e.g. a VGA card on two buses each respond to I/O cycles
on port 0x3c0, but the PCI core will translate the resources to appear
in the kernel space at 0x103c0 for the second one.

We'd have to change pci_ioremap_io to allow mapping less than 64k, but
yes, that would work, too. I don't see an advantage to it though,
other than having io_offset always be zero.

Right, so it also uses io_offset = 0 all the time, which means the
bus I/O port numbers are identical to the Linux I/O port numbers,
but they go beyond 64K on the bus on the second and later links.

I agree.

Now since we are moving the code under common place, probably we should
update this a function a bit so that it invalidates the CPU cache till
line of unification. Just to be consistent with other flush API.
Lorenzo,
Does that make sense ?

Is this required for safety, or is it more a sanity feature?
The architected timer counters are supposed to be monotonic time sources
only, so applying a random offset shouldn't really change anything.
The main thing I can think of is that it is easier for the host to
manage guests' virtual counter offsets if the host's offset is 0 (and
we don't really want to be changing the host offset after the host kernel
boots).

Hmm, in previous years, for arm7xx platforms, boot up was not done by
typical bootloaders.
I've read the code and seems good to me to add "Acked-by".

Subject: [PATCH 3/6] ARM: mm: fix numerous hideous errors in proc-arm740.S
The setup code in proc-arm740.S is completely broken and, as far as I can
tell, always has been. I was >this< close to ripping it out, when a 740t
core-tile materialised in the office, so I've had a crack at fixing things
up:
- Fix the ram/flash area calculations so that we actually set
the condition flags before testing them...
- Fix the proc_info structure so that __cpu_io_mmu_flags are
defined as 0, placing the __cpu_flush pointer at the correct
offset
- Re-number the registers used during __arm740_setup so that
we don't clobber the machine ID et al
- Advertise Thumb support via the hwcaps, since 740T is the only
740 implementation.

Rob, Grant, do either of you know if there's a reason for this that we've
missed?
The gic doesn't have any direct children, and this doesn't seem to be
some decvicetree interrupt-controller magic.
If this is superfluous, how about the patch below?
I took a quick look at arch/arm/boot/dts/. Some gic nodes don't have
#address-cells, some have it but not #size-cells, and some have both. These
should probably be cleaned up too.
[...]
Thanks,
Mark.

Subject: [PATCH] Docs: gic: remove #address-cells from example
The gic has no child nodes, and so doesn't need #address-cells. Having
the property defined in the example only serves as a source of
confusion.

I actually thought about that... but could not think of non-ugly way
of doing that. I hope dts will normally be "right" for any production
system...

* [PATCH] arm: mvebu: enable the SD card slot on Armada 370 Reference Design board
From: Florian Fainelli @ 2013-02-01 10:38 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <20130131175743.GF7717@titan.lakedaemon.net>
The Armada 370 Reference Design board has one SD card slot, directly
connected to the SDIO IP of the SoC, so we enable this IP. there are no
GPIOs for card-detect and write-protect so we do not specify any.

* [PATCH] ARM: OMAP2: AM33XX: id: Add support for AM335x PG2.0
From: AnilKumar Ch @ 2013-02-01 10:28 UTC (permalink / raw)
To: linux-arm-kernel
Add support for chip id recognition of AM335x PG2.0 silicon. By default
omap3xxx_check_revision() recognizes PG1.0, which is extended by adding
PG2.0 support

+NVIDIA Tegra114 Clock And Reset Controller
+
+This binding uses the common clock binding:
+Documentation/devicetree/bindings/clock/clock-bindings.txt
+
+The CAR (Clock And Reset) Controller on Tegra is the HW module responsible
+for muxing and gating Tegra's clocks, and setting their rates.
+
+Required properties :
+- compatible : Should be "nvidia,tegra114-car"
+- reg : Should contain CAR registers location and length
+- clocks : Should contain phandle and clock specifiers for two clocks:
+ the 32 KHz "32k_in", and the board-specific oscillator "osc".
+- #clock-cells : Should be 1.
+ In clock consumers, this cell represents the clock ID exposed by the CAR.
+
+ The first 160 clocks are numbered to match the bits in the CAR's CLK_OUT_ENB
+ registers. These IDs often match those in the CAR's RST_DEVICES registers,
+ but not in all cases. Some bits in CLK_OUT_ENB affect multiple clocks. In
+ this case, those clocks are assigned IDs above 160 in order to highlight
+ this issue. Implementations that interpret these clock IDs as bit values
+ within the CLK_OUT_ENB or RST_DEVICES registers should be careful to
+ explicitly handle these special cases.
+
+ The balance of the clocks controlled by the CAR are assigned IDs of 160 and
+ above.

* [PATCH v5 04/10] clk: tegra: Add new fields and PLL types for Tegra114
From: Peter De Schrijver @ 2013-02-01 10:18 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <1359713962-16822-1-git-send-email-pdeschrijver@nvidia.com>
Tegra114 introduces new PLL types. This requires new clocktypes as well
as some new fields in the pll structure.
Signed-off-by: Peter De Schrijver <pdeschrijver@nvidia.com>

* [PATCH v5 03/10] clk: tegra: Add PLL post divider table
From: Peter De Schrijver @ 2013-02-01 10:18 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <1359713962-16822-1-git-send-email-pdeschrijver@nvidia.com>
Some PLLs in Tegra114 don't use a power of 2 mapping for the post divider.
Introduce a table based approach and switch PLLU to it.

this bit when available.

From: Peter De Schrijver @ 2013-02-01 10:18 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <1359713962-16822-1-git-send-email-pdeschrijver@nvidia.com>
Refactor the PLL programming code to make it useable by the new PLL types
introduced by Tegra114.
The following changes were done:
* Split programming the PLL into updating m,n,p and updating cpcon
* Move locking from _update_pll_cpcon() to clk_pll_set_rate()
* Introduce _get_pll_mnp() helper
* Move check for identical m,n,p values to clk_pll_set_rate()
* struct tegra_clk_pll_freq_table will always contain the values as defined
by the hardware.
* Simplify the arguments to clk_pll_wait_for_lock()
