Merge tag 'staging-4.21-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging
Pull staging/IIO driver updates from Greg KH: "Here is the big staging and iio driver pull request for 4.21-rc1. Lots and lots of tiny patches here, nothing major at all. Which is good, tiny cleanups is nice to see. No new huge driver removal or addition, this release cycle, although there are lots of good IIO driver changes, addtions, and movement from staging into the "real" part of the kernel, which is always great. Full details are in the shortlog, and all of these have been in linux-next for a while with no reported issues" * tag 'staging-4.21-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging: (553 commits) staging: mt7621-mmc: Correct spelling mistakes in comments staging: wilc1000: fix missing read_write setting when reading data mt7621-mmc: char * array declaration might be better as static const mt7621-mmc: return statement in void function unnecessary mt7621-mmc: Alignment should match open parenthesis mt7621-mmc: Removed unnecessary blank lines mt7621-mmc: Fix some coding style issues staging: android: ashmem: doc: Fix spelling staging: rtl8188eu: cleanup brace coding style issues staging: rtl8188eu: add spaces around '&' in rtw_mlme_ext.c staging: rtl8188eu: change return type of is_basicrate() to bool staging: rtl8188eu: simplify null array initializations staging: rtl8188eu: change order of declarations to improve readability staging: rtl8188eu: make some arrays static in rtw_mlme_ext.c staging: rtl8188eu: constify some arrays staging: rtl8188eu: convert unsigned char arrays to u8 staging: rtl8188eu: remove redundant declaration in rtw_mlme_ext.c staging: rtl8188eu: remove unused arrays WFD_OUI and WMM_INFO_OUI staging: rtl8188eu: remove unnecessary parentheses in rtw_mlme_ext.c staging: rtl8188eu: remove unnecessary comments in rtw_mlme_ext.c ...

+MediaTek MT7621 PCIe controller
+
+Required properties:
+- compatible: "mediatek,mt7621-pci"
+- device_type: Must be "pci"
+- reg: Base addresses and lengths of the PCIe subsys and root ports.
+- bus-range: Range of bus numbers associated with this controller.
+- #address-cells: Address representation for root ports (must be 3)
+- pinctrl-names : The pin control state names.
+- pinctrl-0: The "default" pinctrl state.
+- #size-cells: Size representation for root ports (must be 2)
+- ranges: Ranges for the PCI memory and I/O regions.
+- #interrupt-cells: Must be 1
+- interrupt-map-mask and interrupt-map: Standard PCI IRQ mapping properties.
+ Please refer to the standard PCI bus binding document for a more detailed
+ explanation.
+- status: either "disabled" or "okay".
+- resets: Must contain an entry for each entry in reset-names.
+ See ../reset/reset.txt for details.
+- reset-names: Must be "pcie0", "pcie1", "pcieN"... based on the number of
+ root ports.
+- clocks: Must contain an entry for each entry in clock-names.
+ See ../clocks/clock-bindings.txt for details.
+- clock-names: Must be "pcie0", "pcie1", "pcieN"... based on the number of
+ root ports.
+
+In addition, the device tree node must have sub-nodes describing each PCIe port
+interface, having the following mandatory properties:
+
+Required properties:
+- reg: Only the first four bytes are used to refer to the correct bus number
+ and device number.
+- #address-cells: Must be 3
+- #size-cells: Must be 2
+- ranges: Sub-ranges distributed from the PCIe controller node. An empty

+1) Revisit multi-cards options and PCM route mixer control (as per comment

-1) Document the device tree node
-
-The downstream tree(the tree that the driver was imported from) at
-http://www.github.com/raspberrypi/linux uses this node:
-
-audio: audio {
- compatible = "brcm,bcm2835-audio";
- brcm,pwm-channels = <8>;
-};
-
-Since the driver requires the use of VCHIQ, it may be useful to have a link
-in the device tree to the VCHIQ driver.
-
-2) Gracefully handle the case where VCHIQ is missing from the device tree or
-it has not been initialized yet.
-
-3) Review error handling and remove duplicate code.
-
-4) Cleanup the logging mechanism. The driver should probably be using the
-standard kernel logging mechanisms such as dev_info, dev_dbg, and friends.
-
-5) Fix the remaining checkpatch.pl errors and warnings.

A short top-down description of this driver's architecture (function of
kthreads, userspace, limitations) could be very helpful for reviewers.
+
+7) Review and comment memory barriers
+
+There is a heavy use of memory barriers in this driver, it would be very
+beneficial to go over all of them and, if correct, comment on their merits.
+Extra points to whomever confidently reviews the remote_event_*() family of
+functions.
+
+8) Get rid of custom function return values
+
+Most functions use a custom set of return values, we should force proper Linux
+error numbers. Special care is needed for VCHIQ_RETRY.
+
+9) Reformat core code with more sane indentations
+
+The code follows the 80 characters limitation yet tends to go 3 or 4 levels of
+indentation deep making it very unpleasant to read. This is specially relevant
+in the character driver ioctl code and in the core thread functions.
+
+10) Reorganize file structure: Move char driver to it's own file and join both
+platform files
+
+The cdev is defined alongside with the platform code in vchiq_arm.c. It would
+be nice to completely decouple it from the actual core code. For instance to be
+able to use bcm2835-audio without having /dev/vchiq created. One could argue
+it's better for security reasons or general cleanliness. It could even be
+interesting to create two different kernel modules, something the likes of
+vchiq-core.ko and vchiq-dev.ko. This would also ease the upstreaming process.
+
+The code in vchiq_bcm2835_arm.c should fit in the generic platform file.
+
+12) Get rid of all the struct typedefs
+
+Most structs are typedefd, it's not encouraged in the kernel.
+
+13) Get rid of all non essential global structures and create a proper per
+device structure
+
+The first thing one generally sees in a probe function is a memory allocation
+for all the device specific data. This structure is then passed all over the
+driver. This is good practice since it makes the driver work regardless of the
+number of devices probed.
