We only want to modify these arrays inside the parser "drivers", so the
drivers should construct them however they like, then return them as
immutable arrays.
This will make other refactorings easier.

It's easier to refactor these parsers if the return value gets assigned
only once, just like every other MTD partition parser.
This prepares for making the second arg to the parse_fn() const. This is
OK if we construct the partitions completely first, and assign them to
the return pointer only after we're done modifying them.

A few MAINTAINERS updates, and some DT binding/documentation fixups.
Signed-off-by: Brian Norris <computersforpeace@gmail.com>
|

As noted here [1], there are potentially future conflicts if we try to
use MTD's "partitions" subnode to describe anything besides just the
fixed-in-the-device-tree partitions currently described in this
document. Particularly, there was a proposal to use this node for the
AFS parser too.
It can pose a (small) problem to try to differentiate the following
nodes:
// using binding as currently specified
partitions {
#address-cells = <x>;
#size-cells = <y>;
partition@0 {
...;
};
};
and
// proposed future binding
partitions {
compatible = "arm,arm-flash-structure";
};
It's especially difficult if other uses of this node start having
subnodes.
So, since the "partitions" node is new in v4.4, let's fixup the binding
before release so that it requires a compatible property, so it's much
clearer to distinguish. e.g.:
// proposed
partitions {
compatible = "fixed-partitions";
#address-cells = <x>;
#size-cells = <y>;
partition@0 {
...;
};
};

Calling synchronize_irq() right before free_irq() is quite useless. On one
hand the IRQ can easily fire again before free_irq() is entered, on the
other hand free_irq() itself calls synchronize_irq() internally (in a race
condition free way), before any state associated with the IRQ is freed.
Patch was generated using the following semantic patch:

-synchronize_irq(irq);

The ofpart partition parser might be run on DT-enabled systems that
don't have any "ofpart" partition subnodes at all, since "ofpart" is in
the default parser list. So don't complain loudly on every boot.
Example: using m25p80.c with no intent to use ofpart:
&spi2 {
status = "okay";
flash@0 {
compatible = "jedec,spi-nor";
reg = <0>;
};
};
I see this warning:

MTD allows compile-time configuration of the possible CFI geometry
settings that are allowed by the kernel, but that includes a couple of
invalid configurations, where no bank width or no interleave setting
is allowed. These are then caught with a compile-time warning:
include/linux/mtd/cfi.h:76:2: warning: #warning No CONFIG_MTD_CFI_Ix selected. No NOR chip support can work.
include/linux/mtd/map.h:145:2: warning: #warning "No CONFIG_MTD_MAP_BANK_WIDTH_xx selected. No NOR chip support can work"
This is a bit annoying for randconfig tests, and can be avoided if
we change the Kconfig logic to always select the simplest configuration
when no other one is enabled.

Commit 43163022927b ("mtd: m25p80: allow arbitrary OF matching for
"jedec,spi-nor"") moved the "jedec,spi-nor" handling from the
spi_device_id table to the of_match_table, to better handle matching
complex device tree compatible strings. With that patch, device tree
support works as expected when m25p80.c is built into the kernel.
However, that commit ignored the fact that:
(1) (non-DT) platform devices might want to use the "spi-nor" string
for matching with this driver, rather than picking an arbitrary one
like "m25p80"
(2) the core SPI uevent/modalias code doesn't yet support kernel module
autoloading via of_match_table strings; so for DT-based devices, it
will only report (part of) the first compatible string used
Problem (1) has been reported previously, and I forgot to patch it up
afterward.
Problem (2) was noticed recently here:
http://lists.infradead.org/pipermail/linux-mtd/2015-October/062369.html
https://lkml.org/lkml/2015/11/12/574
Specifically, this patch fixes m25p80.ko module autoloading for cases
like this:
flash@xxx {
compatible = "jedec,spi-nor";
...
};
because modalias of "spi:spi-nor" (the only module loading info provided
by the SPI core for this device) will now be listed as an alias in
m25p80.ko.
Notably, it does *not* help cases like this:
flash@xxx {
compatible = "vendor,shiny-new-device", "jedec,spi-nor";
...
};
unless we also list "shiny-new-device" in m25p_ids[]. There has been
discussion on future work for this issue here:

The ->priv field of the mtd_info object attached to a nand_chip device
should point to the nand_chip device. The pxa and cafe drivers are
assigning this field their own private structure, which works fine as long
as the nand_chip field is the first one in the driver private struct but
seems a bit fragile.
Fix that by setting mtd->priv to point the nand_chip field and assigning
chip->priv to the private structure head.

The Data Flash Control Register (NDCR) contains two types
of parameters: those that are needed for device identification,
and those that can only be set after device identification.
Therefore, the driver can't set them all at once and instead
needs to configure the first group before nand_scan_ident()
and the second group later.
Let's split pxa3xx_nand_config in two halves, and set the
parameters that depend on the device geometry once this is known.

The chunk size represents the size of the data chunks, which
is used by the controllers that allow to split transfered data.
However, the initial chunk size is used in a non-splitted way,
during device identification. Therefore, it must be large enough
for all the NAND commands issued during device identification.
This includes NAND_CMD_PARAM which was recently changed to
transfer up to 2048 bytes (for the redundant parameter pages).
Thus, the initial chunk size should be 2048 as well.
On Armada 370/XP platforms (NFCv2) booted without the keep-config
devicetree property, this commit fixes a timeout on the NAND_CMD_PARAM

If multiple NAND chips are registered to the same controller, then when
rebooting the system, the first one will grab the controller lock, while
the second will wait forever for the first one to release it. i.e., a
classic deadlock.
This problem was solved for a similar case (suspend/resume) back in
commit 6b0d9a841249 ("mtd: nand: fix multi-chip suspend problem"), and
the shutdown state really isn't much different for us, so rather than
adding a new special case to nand_get_device(), we can just overload the
FL_PM_SUSPENDED state.
Now, multiple chips can "get" the same controller lock (preventing
further I/O), while we still allow other chips to pass through
nand_shutdown().

Pull final round of SCSI updates from James Bottomley:
"Sorry for the delay in this patch which was mostly caused by getting
the merger of the mpt2/mpt3sas driver, which was seen as an essential
item of maintenance work to do before the drivers diverge too much.
Unfortunately, this caused a compile failure (detected by linux-next),
which then had to be fixed up and incubated.
In addition to the mpt2/3sas rework, there are updates from pm80xx,
lpfc, bnx2fc, hpsa, ipr, aacraid, megaraid_sas, storvsc and ufs plus
an assortment of changes including some year 2038 issues, a fix for a
remove before detach issue in some drivers and a couple of other minor
issues"

Pull SCSI target updates from Nicholas Bellinger:
"This series contains HCH's changes to absorb configfs attribute
->show() + ->store() function pointer usage from it's original
tree-wide consumers, into common configfs code.
It includes usb-gadget, target w/ drivers, netconsole and ocfs2
changes to realize the improved simplicity, that now renders the
original include/target/configfs_macros.h CPP magic for fabric drivers
and others, unnecessary and obsolete.
And with common code in place, new configfs attributes can be added
easier than ever before.
Note, there are further improvements in-flight from other folks for
v4.5 code in configfs land, plus number of target fixes for post -rc1
code"
In the meantime, a new user of the now-removed old configfs API came in
through the char/misc tree in commit 7bd1d4093c2f ("stm class: Introduce
an abstraction for System Trace Module devices").
This merge resolution comes from Alexander Shishkin, who updated his stm
class tracing abstraction to account for the removal of the old
show_attribute and store_attribute methods in commit 517982229f78
("configfs: remove old API") from this pull. As Alexander says about
that patch:
"There's no need to keep an extra wrapper structure per item and the
awkward show_attribute/store_attribute item ops are no longer needed.
This patch converts policy code to the new api, all the while making
the code quite a bit smaller and easier on the eyes.
Signed-off-by: Alexander Shishkin <alexander.shishkin@linux.intel.com>"
That patch was folded into the merge so that the tree should be fully
bisectable.
