Lots of different types of driver things in here, as this tree seems to be the "collection of various driver subsystems not big enough to have their own git tree" lately. Anyway, some highlights of the changes in here: - binderfs: is it a rule that all driver subsystems will eventually grow to have their own filesystem? Binder now has one to handle the use of it in containerized systems. This was discussed at the Plumbers conference a few months ago and knocked into mergable shape very fast by Christian Brauner. Who also has signed up to be another binder maintainer, showing a distinct lack of good judgement :) - binder updates and fixes - mei driver updates - fpga driver updates and additions - thunderbolt driver updates - soundwire driver updates - extcon driver updates - nvmem driver updates - hyper-v driver updates - coresight driver updates - pvpanic driver additions and reworking for more device support - lp driver updates. Yes really, it's _finally_ moved to the proper parallal port driver model, something I never thought I would see happen. Good stuff. - other tiny driver updates and fixes.

* mtd: part: Create the master device node when partitionedDan Ehrenberg2015-04-061-0/+13
| | | | | | | | | | | | | | | | | | | For many use cases, it helps to have a device node for the entire MTD device as well as device nodes for the individual partitions. For example, this allows querying the entire device's properties. A common idiom is to create an additional partition which spans over the whole device. This patch makes a config option, CONFIG_MTD_PARTITIONED_MASTER, which makes the master partition present even when the device is partitioned. This isn't turned on by default since it presents a backwards-incompatible device numbering. The patch also makes the parent of a partition device be the master, if the config flag is set, now that the master is a full device.

* mtd: merge mtdchar module with mtdcoreArtem Bityutskiy2013-04-051-13/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The MTD subsystem has historically tried to be as configurable as possible. The side-effect of this is that its configuration menu is rather large, and we are gradually shrinking it. For example, we recently merged partitions support with the mtdcore. This patch does the next step - it merges the mtdchar module to mtdcore. And in this case this is not only about eliminating too fine-grained separation and simplifying the configuration menu. This is also about eliminating seemingly useless kernel module. Indeed, mtdchar is a module that allows user-space making use of MTD devices via /dev/mtd* character devices. If users do not enable it, they simply cannot use MTD devices at all. They cannot read or write the flash contents. Is it a sane and useful setup? I believe not. And everyone just enables mtdchar. Having mtdchar separate is also a little bit harmful. People sometimes miss the fact that they need to enable an additional configuration option to have user-space MTD interfaces, and then they wonder why on earth the kernel does not allow using the flash? They spend time asking around. Thus, let's just get rid of this module and make it part of mtd core. Note, mtdchar had additional configuration option to enable OTP interfaces, which are present on some flashes. I removed that option as well - it saves a really tiny amount space. [dwmw2: Strictly speaking, you can mount file systems on MTD devices just fine without the mtdchar (or mtdblock) devices; you just can't do other manipulations directly on the underlying device. But still I agree that it makes sense to make this unconditional. And Yay! we get to kill off an instance of checking CONFIG_foo_MODULE, which is an abomination that should never happen.] Signed-off-by: Artem Bityutskiy <artem.bityutskiy@linux.intel.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | There are very few situations where MTD partitioning is not required, and the benefit in code size reduction by making this configurable does not warrant the level of ifdeffery needed. Artem: this patch is not final - we just make sure that mtd partitions are always compiled in, and at the end of the series we'll kill MTD_PARTITIONS altogether.

* mtd: make MTD_CONCAT support mandatoryDmitry Eremin-Solenikov2011-03-111-1/+2
| | | | | | | | | | | | | | | | | Move mtdconcat to be an integral part of the mtd core. It's a tiny bit of code, which bears 'say Y if you don't know what to do' note in the Kconfig. OTOH there are several ugly ifdefs depending on the MTD_CONCAT. So, making MTD_CONCAT support mandatory will allow us to clean up code a lot. Kconfig entry is changed to be a bool defaulting to Y, so all code pieces depending on it, will have MTD_CONCAT Kconfig symbol and CONFIG_MTD_CONCAT define. This will be removed in one of next patches.

| | | | | | | | | | | | | MTD_OF_PARTS should be possible on all architectures, not just powerpc and microblaze, and it probably should not be a user selectable option. Neither does it need to be in a separate module. Also, rework MTD Kconfig to group options dependant on MTD_PARTITIONS into a if/endif block. Do the same for MTD_REDBOOT_PARTS.

| | | | | | | | | | | | | | | | | | | Randy Dunlap observed a build problem with the following config: CONFIG_SM_FTL=y CONFIG_SM_FTL_MUSEUM=y CONFIG_MTD_NAND=m The ECC calculation routines are then built as a module, but referenced by the sm_ftl code in the kernel, resulting in a build failure. The simple fix is to make CONFIG_SM_FTL depend on MTD_NAND unconditionally -- it's pointless without hardware support anyway. Fix some typos which Randy pointed out, too.
