I will ack the patch that removes the mach-virt directory altogether!

So Marc's plan has actually happened. Neat. In that case is there even
any point in listing explicit compatiblity strings (except perhaps as a
historical note) -- I can just say that this is the fallback/default
machine?
I'll leave the virt_init change to a separate patch if that's ok.

This isn't particularly scientific, but maybe a practical criteria could be
that it's mentioned in this thread? I think if we word the introduction to the
list clearly, readers will know that that these are just a few examples known
to be in use when the binding was written and by no means required. I think
that providing more information is more likely to fix the incorrect assumption
than providing less information.

Yes, I assumed you would include Xen. I'm not aware of any others*, but
perhaps those who do could speak up about them?
(*I do use Angel semihosting and DCC from time to time, but I've never seen
devicetree bindings for these facilities. I'm not sure whether they count in
this context.)

Rob,
Do you agree on increasing MAX_PHANDLE_ARGS to 32?
Or should this be done when someone (e.g. Suravee) submits a DTS
update with an SMMU node description containing more than 16 stream
IDs for a master device?

I better think about a 'normal' DT definition:
- in the DT, define the tda998x in a i2c subnode:
&i2c0 {
tda998x: hdmi-encoder {
compatible = "nxp,tda998x";
reg = <0x70>;
/* the video ports are OK by default */
/* define the interrupt if you want to use it */
};
};
- in tilcdc_slave.c, in the function slave_encoder_create(), instead of
using drm_i2c_encoder_init(), do quite the same, but without calling
request_module() nor i2c_new_device().
This can be done as follows (the code is not compiled):
--------------------8<---------------------
static struct drm_encoder *slave_encoder_create(struct drm_device *dev,
struct slave_module *mod)
{
struct slave_encoder *slave_encoder;
struct drm_encoder *encoder;
int ret;
/* ------ added ------ */
struct device_node *np;
static const struct of_device_id tda_dt[] = {
{ .compatible = "nxp,tda998x" },
{ },
};
/* ------ end added ------ */
... no change ...
drm_encoder_helper_add(encoder, &slave_encoder_helper_funcs);
/* ------ added ------ */
/* search the tda998x device */
np = of_find_matching_node_and_match(NULL, tda_dt, NULL);
if (np && of_device_is_available(np)) {
struct i2c_client *i2c_client;
struct drm_i2c_encoder_driver *encoder_drv;
struct module *module;
/* the tda998x is in the DT */
i2c_client = of_find_i2c_device_by_node(np);
of_node_put(np);
if (!i2c_client) {
dev_err(dev->dev, "no tda998x i2c client\n");
goto fail;
}
to_encoder_slave(encoder)->bus_priv = i2c_client;
encoder_drv = to_drm_i2c_encoder_driver(
to_i2c_driver(i2c_client->dev.driver));
/* lock the tda998x module in memory */
module = to_i2c_driver(i2c_client->dev.driver)->driver.owner;
if (!module || !try_module_get(module)) {
dev_err(dev->dev, "cannot get module %s\n", module->name);
goto fail;
}
ret = encoder_drv->encoder_init(i2c_client, dev, encoder_slave);
if (ret < 0) {
dev_err(dev->dev, "slave encoder init failed\n");
module_put(module);
goto fail;
}
/* set_config is useless */
return encoder;
}
/* ------ end added ------ */
ret = drm_i2c_encoder_init(dev, to_encoder_slave(encoder), mod->i2c, &info);
if (ret)
goto fail;
return encoder;
fail:
slave_encoder_destroy(encoder);
return NULL;
}
--------------------8<---------------------
When the tda998x is in the DT, the i2c_client is already created.
It must not be freed, and so, the function drm_i2c_encoder_destroy()
must not be called. But, the module must be explicitly unlocked in
slave_encoder_destroy(), and then, there must be some flag in the
structures for this job to be done...

* [PATCH v2] clk: keystone: gate: fix clk_init_data initialization
From: Ivan Khoronzhuk @ 2014-01-30 18:03 UTC (permalink / raw)
To: linux-arm-kernel
The clk_init_data struct is allocated in the stack. All members of
this struct should be initialized before using otherwise it will
lead to unpredictable situation as it can contain garbage.
Ultimately the clk->flag field contains garbage. In my case it leads
that flag CLK_IGNORE_UNUSED is set for most of clocks. As result a
bunch of unused clocks cannot be disabled.
So initialize flags in this structure too.

Yeah, but those are driver problems, right? 1400 suspends is very
nice, and it shows that the core is working. That should be enough for
merge; driver problems can be solved later.

The clobbers. For example:
arch/arm64/kvm/sys_regs.c:
/* Make sure noone else changes CSSELR during this! */
local_irq_disable();
/* Put value into CSSELR */
asm volatile("msr csselr_el1, %x0" : : "r" (csselr));
isb();
/* Read result out of CCSIDR */
asm volatile("mrs %0, ccsidr_el1" : "=r" (ccsidr));
local_irq_enable();
Just about everything can be re-ordered in that block, because the asm
volatile statements don't have "memory" clobbers.
I think it's worth checking the rest of the kernel, too.

Ah, I missed the other __NR_* uses in the generic audit_*.h files. Below
is an attempt to add compat __NR_* definitions to arm64 unistd32.h.
There are other ways of doing this and still avoid collision with the
native ones but I thought that's the easiest. Note that these are not
uapi headers, so they are just for the kernel. Compile-tested only (and
please check, maybe my vim macros and regexp got something wrong):
(and in the process I found two new AArch32 syscalls which I'll add to
the compat layer)

Subject: [PATCH] arm64: Add __NR_* definitions for compat syscalls
This patch adds __NR_* definitions to asm/unistd32.h, moves the
__NR_compat_* definitions to asm/unistd.h and removes all the explicit
unistd32.h includes apart from the one building the compat syscall
table. The aim is to have the compat __NR_* definitions available but
without colliding with the native syscall definitions.

* [PATCH] ARM: dts: msm: split out msm8660 and msm8960 soc into dts include
From: Kumar Gala @ 2014-01-30 18:08 UTC (permalink / raw)
To: linux-arm-kernel
Pull the SoC device tree bits into their own files so other boards based
on these SoCs can include them and reduce duplication across a number of
boards.

* [PATCH v2] ARM: keystone: dts: drop "msmcsram" clock node
From: Ivan Khoronzhuk @ 2014-01-30 18:10 UTC (permalink / raw)
To: linux-arm-kernel
At late init all unused clocks are disabled. So clocks that were not
get before will be gated. In Keysone 2 SoC we have at least one
necessary clock that is not used by any driver - "msmcsram". This
clock is necessary, because it supplies the Multicore Shared Memory
Controller (MSMC). MSMC is the coherency interconnect and all the
coherent masters are connected to it including devices which are not
under Linux OS control. MSMC clock should not be touched even in low
power states.
So drop the clock node, otherwise 'clk_ignore_unused' parameter will
disable the clock leading to system stall.

* [PATCH 0/6] iommu/arm-smmu: Misc modifications to support SMMUs on Calxeda ECX-2000
From: Andreas Herrmann @ 2014-01-30 18:18 UTC (permalink / raw)
To: linux-arm-kernel
Hi,
This is v5 of my arm-smmu changes (to support SMMUs on Calxeda ECX-2000).
Patches are based on v3.13.
Changes to previous version are
- use iommu_group notifier instead of bus notifier
- remove superfluous call to arm_smmu_add_device in
notifier function
- free bitmap that's used for checking of duplicate stream IDs
- hopefully addressed all issues for the "SMR allocator" patch
(see http://marc.info/?l=linux-arm-kernel&m=139040446813960)
- reorder patches to put the notifier change last (in case there are
still objections to this the rest could be merged I think)
I omitted the patches that are device-tree related (of, dts,
documentation) or ARM dma-mapping.c related. I'll work on an update of
the dma-mapping change (to automatically increase the mapping size)
separately.
Changelog:
v4:
http://marc.info/?l=linux-arm-kernel&m=138988209913055

* [PATCH 1/6] iommu/arm-smmu: Introduce driver option handling
From: Andreas Herrmann @ 2014-01-30 18:18 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <1391105889-32718-1-git-send-email-andreas.herrmann@calxeda.com>
Introduce handling of driver options. Options are set based on DT
information when probing an SMMU device. The first option introduced
is "arm,smmu-isolate-devices". (It will be used in the iommu_group
notifier block.)

In such a case we have to use secure aliases of some non-secure
registers.
This handling is switched on by DT property
"calxeda,smmu-secure-config-access" for an SMMU node.

* [PATCH 3/6] iommu/arm-smmu: Check for duplicate stream IDs when registering master devices
From: Andreas Herrmann @ 2014-01-30 18:18 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <1391105889-32718-1-git-send-email-andreas.herrmann@calxeda.com>
If DT information lists one stream ID twice for the master devices of
an SMMU this can cause a multi match when stream ID matching is used.
For stream ID indexing this might trigger an overwrite of an S2CR that
is already in use.
So better check for duplicates when DT information is parsed.

* [PATCH 4/6] iommu/arm-smmu: Introduce automatic stream-id-masking

To: linux-arm-kernel
In-Reply-To: <1391105889-32718-1-git-send-email-andreas.herrmann@calxeda.com>
Try to determine mask/id values that match several stream IDs of a
master device when doing Stream ID matching. Thus the number of used
SMR groups that are required to map all stream IDs of a master device
to a context should be less than the number of SMR groups used so far
(currently one SMR group is used for one stream ID).

* [PATCH 5/6] iommu/arm-smmu: Set MAX_MASTER_STREAMIDS to MAX_PHANDLE_ARGS
From: Andreas Herrmann @ 2014-01-30 18:18 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <1391105889-32718-1-git-send-email-andreas.herrmann@calxeda.com>
The DT parsing code that determines stream IDs uses
of_parse_phandle_with_args and thus MAX_MASTER_STREAMIDS
is always bound by MAX_PHANDLE_ARGS.

* [PATCH 6/6] iommu/arm-smmu: Introduce iommu_group notifier block
From: Andreas Herrmann @ 2014-01-30 18:18 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <1391105889-32718-1-git-send-email-andreas.herrmann@calxeda.com>
At the moment just handle IOMMU_GROUP_NOTIFY_BIND_DRIVER to
conditionally isolate all master devices for an SMMU.
Depending on DT information each device is put into its own protection
domain (if possible). For configuration with one or just a few
masters per SMMU that is easy to achieve.
In case of many devices per SMMU (e.g. MMU-500 with it's distributed
translation support) isolation of each device might not be possible --
depending on number of available SMR groups and/or context banks.
Default is that device isolation is contolled per SMMU with SMMU node
property "arm,smmu-isolate-devices" in a DT. If this property is set
for an SMMU node, device isolation is performed.
W/o device isolation the driver detects SMMUs but no translation is
configured (transactions just bypass translation process).
Note that for device isolation dma_base and size are fixed as 0 and
SZ_128M at the moment. Additional patches will address this
restriction and allow automatic growth of mapping size.

Hi Pavel,
I spoke to Russ, and he's ok with me sending this on his behalf.
Let me prepare it for review and I'll send it out.

Hi Sebastian
I think there might be something wrong here....
/debug/pinctrl/f1010000.pinctrl/pinconf-groups used to contain:
Pin config settings per pin group
Format: group (name): configs
0 (mpp0):current: spi(cs), available = [ gpio(io) nand(io2) ]
1 (mpp1):current: spi(mosi), available = [ gpo(o) nand(io3) ]
2 (mpp2):current: spi(sck), available = [ gpo(o) nand(io4) ]
3 (mpp3):current: spi(miso), available = [ gpo(o) nand(io5) ]
4 (mpp4):current: sata1(act), available = [ gpio(io) nand(io6) uart0(rxd) lcd(hsync) ]
5 (mpp5):current: sata0(act), available = [ gpo(o) nand(io7) uart0(txd) lcd(vsync) ]
6 (mpp6):current: sysrst(out), available = [ spi(mosi) ]
...
It now has:
Pin config settings per pin group
Format: group (name): configs
0 (mpp0):current: gpio(io), available = [ nand(io2) spi(cs) ]
1 (mpp1):current: gpo(o), available = [ nand(io3) spi(mosi) ]
2 (mpp2):current: gpo(o), available = [ nand(io4) spi(sck) ]
3 (mpp3):current: gpo(o), available = [ nand(io5) spi(miso) ]
4 (mpp4):current: gpio(io), available = [ nand(io6) uart0(rxd) sata1(act) lcd(hsync) ]
5 (mpp5):current: gpo(o), available = [ nand(io7) uart0(txd) sata0(act) lcd(vsync) ]
6 (mpp6):current: UNKNOWN, available = [ sysrst(out) spi(mosi) ]
The device i'm testing on does use spi and sata, so i would say the
old contents was correct and the new is wrong.

Wouldn't it be better to read this value from the l2 cache
controller node? I'd assume there might be more SoCs that
will need a similar change, so it's better to come up with
a solution that doesn't involve changing the kernel every
time.

* [PATCH 0/4] Split mach-msm into legacy and mach-qcom (multiplatform)
From: Kumar Gala @ 2014-01-30 18:36 UTC (permalink / raw)
To: linux-arm-kernel
This is the starts of splitting the Qualcomm MSM platform into legacy support
that we will not try and convert to multiplatform and multiplatform support.
These patches are based on the 'CPU enable method based SMP' patches.
I wanted to get these out for review, will add a few more patches for defconfig
updates/additions, as well as some additional driver being enabled for ARCH_QCOM.
