2021-11-27iio: expose shared parameter in IIO_ENUM_AVAILABLEAntoniu Miclaus21-38/+31
The shared parameter should be configurable based on its usage, and not constrained to IIO_SHARED_BY_TYPE. This patch aims to improve the flexibility in using the IIO_ENUM_AVAILABLE define and avoid redefining custom iio enums that expose the shared parameter. An example is the ad5766.c driver where IIO_ENUM_AVAILABLE_SHARED was defined in order to achieve `shared` parameter customization. The current state of the IIO_ENUM_AVAILABLE implementation will imply similar redefinitions each time a driver will require access to the `shared` parameter. An example would be admv1013 driver which will require custom device attribute for the frequency translation modes: Quadrature I/Q mode and Intermediate Frequency mode.

Using `dev_get_drvdata()` in IIO sysfs callbacks to get a pointer to the IIO device is a relic from the very early days of IIO. The IIO core as well as most other drivers have switched over to using `dev_to_iio_dev()` instead. This driver is one of the last few drivers remaining that uses the outdated idiom, update it. This will allow to eventually update the IIO core to no longer set the drvdata for the IIO device and free it up for driver usage.

2021-11-17iio: at91-sama5d2: Fix incorrect cast to platform_deviceLars-Peter Clausen1-18/+16
The at91-sama5d2 driver calls `to_platform_device()` on a struct device that is part of a IIO device. This is incorrect since `to_platform_device()` must only be called on a struct device that is part of a platform device. The code still works by accident because non of the struct platform_device specific fields are accessed. Refactor the code a bit so that it behaves identically, but does not use the incorrect cast. This avoids accidentally adding undefined behavior in the future by assuming the `struct platform_device` is actually valid.

2021-11-17iio: imx7d_adc: Don't pass IIO device to imx7d_adc_{enable,disable}()Lars-Peter Clausen1-3/+2
The `imx7d_adc_enable()` and `imx7d_adc_disable()` functions are used as the suspend and resume callbacks for the device. When called as suspend/resume functions they are called with the platform_device's device as their parameter. In addition the functions are called on device probe and remove. In this case they are passed the struct device of the IIO device that the driver registers. This works because in the `imx7d_adc_{enable,disable}()` functions the passed struct device is only ever used as a parameter to `dev_get_drvdata()` and `dev_get_drvdata()` returns the same value for the platform device and the IIO device. But for consistency we should pass the same struct device to the `imx7d_adc_{enable,disable}()` in all cases. This will avoid accidental breakage if the device is ever used for something more than `dev_get_drvdata()`. Another motivation is that `dev_get_drvdata()` on the IIO device relies on the IIO core calling `dev_set_drvdata()`. Something we want to remove.

2021-11-17iio: xilinx-xadc: Make IRQ optionalLars-Peter Clausen1-22/+40
In some setups the IRQ signal of the XADC might not be wired to the host system. The driver currently requires that an interrupt is specified. Make the interrupt optional so the driver can be used in such setups where the interrupt is not connected. Since both the internal triggers as well as events depend on the interrupt being connected both are not available when the interrupt is not connected. Buffered access is still supported even without an interrupt since an external trigger can be used. The IRQ is only optional when using the AXI interface, since the PCAP interface needs the IRQ for reading and writing registers.

Special thanks to Nathan Chancellor who fixed the Clang bug[1][2]. This bugfix only appears in Clang 14.0.0, so older versions still contain the bug and -Wimplicit-fallthrough won't be enabled for them, for now. This concludes a long journey and now we are finally getting rid of the unintentional fallthrough bug-class in the kernel, entirely. :) Link: https://github.com/llvm/llvm-project/commit/9ed4a94d6451046a51ef393cd62f00710820a7e8 [1] Link: https://bugs.llvm.org/show_bug.cgi?id=51094 [2] Link: https://github.com/KSPP/linux/issues/115 Link: https://github.com/ClangBuiltLinux/linux/issues/236 Co-developed-by: Kees Cook <keescook@chromium.org> Signed-off-by: Kees Cook <keescook@chromium.org> Co-developed-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Gustavo A.

Pull xfs cleanups from Darrick Wong: "The most 'exciting' aspect of this branch is that the xfsprogs maintainer and I have worked through the last of the code discrepancies between kernel and userspace libxfs such that there are no code differences between the two except for #includes. IOWs, diff suffices to demonstrate that the userspace tools behave the same as the kernel, and kernel-only bits are clearly marked in the /kernel/ source code instead of just the userspace source. Summary: - Clean up open-coded swap() calls. - A little bit of #ifdef golf to complete the reunification of the kernel and userspace libxfs source code" * tag 'xfs-5.16-merge-5' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux: xfs: sync xfs_btree_split macros with userspace libxfs xfs: #ifdef out perag code for userspace xfs: use swap() to make dabtree code cleaner
