2025-05-21tools/nolibc: include nolibc.h early from all header filesThomas Weißschuh20-63/+60
Inclusion of any nolibc header file should also bring all other headers. On the other hand it should also be possible to include any nolibc header files in any order. Currently this is implemented by including the catch-all nolibc.h after the headers own definitions. This is problematic if one nolibc header depends on another one. The first header has to include the other one before defining any symbols. That in turn will include the rest of nolibc while the current header has not defined anything yet. If any other part of nolibc depends on definitions from the current header, errors are encountered. This is already the case today. Effectively nolibc can only be included in the order of nolibc.h. Restructure the way "nolibc.h" is included. Move it to the beginning of the header files and before the include guards. Now any header will behave exactly like "nolibc.h" while the include guards prevent any duplicate definitions.

2025-05-21tools/nolibc: add target to check header usabilityThomas Weißschuh1-0/+9
Each nolibc header should be valid for inclusion irrespective of any special ordering requirements. Add a new make target, based on the old kbuild "make header_check" target to validate this requirement. For now the check fails, but the following commits will fix the issues.

2025-05-21efi: zboot specific mechanism for embedding SBAT sectionVitaly Kuznetsov4-2/+59
SBAT is a mechanism which improves SecureBoot revocations of UEFI binaries by introducing a generation-based technique. Compromised or vulnerable UEFI binaries can be prevented from booting by bumping the minimal required generation for the specific component in the bootloader. More information on the SBAT can be obtained here: https://github.com/rhboot/shim/blob/main/SBAT.md Upstream Linux kernel does not currently participate in any way in SBAT as there's no existing policy in how SBAT generation number should be defined. Keep the status quo and provide a mechanism for distro vendors and anyone else who signs their kernel for SecureBoot to include their own SBAT data. This leaves the decision on the policy to the vendor. Basically, each distro implementing SecureBoot today, will have an option to inject their own SBAT data during kernel build and before it gets signed by their SecureBoot CA. Different distro do not need to agree on the common SBAT component names or generation numbers as each distro ships its own 'shim' with their own 'vendor_cert'/'vendor_db' Implement support for embedding SBAT data for architectures using zboot (arm64, loongarch, riscv). Put '.sbat' section in between '.data' and '.text' as the former also covers '.bss' and thus must be the last one.

2025-05-21dt-bindings: iio: adc: Add ROHM BD79100GMatti Vaittinen1-29/+34
The ROHM BD79100G is a 12-bit ADC which can be read over SPI. Device has no MOSI pin. ADC results can be read from MISO by clocking in 16 bits. The 4 leading bits will be zero, last 12 containig the data. Device has only VCC supply pin, which acts also as a VFS, determining the voltage for full 12-bits. Specifying it is mandatory. This seems identical to the ti,ads7866. Support ROHM BU79100G using ti,ads7866 as a fallback.

2025-05-21iio: adc: ad4695: use IIO_DECLARE_DMA_BUFFER_WITH_TSDavid Lechner1-2/+1
Use IIO_DECLARE_DMA_BUFFER_WITH_TS() to declare the buffer that gets used with iio_push_to_buffers_with_ts(). This makes the code a bit easier to read and understand.

2025-05-21iio: introduce IIO_DECLARE_BUFFER_WITH_TS macrosDavid Lechner1-0/+32
Add new macros to help with the common case of declaring a buffer that is safe to use with iio_push_to_buffers_with_ts(). This is not trivial to do correctly because of the alignment requirements of the timestamp. This will make it easier for both authors and reviewers. To avoid double __align() attributes in cases where we also need DMA alignment, add a 2nd variant IIO_DECLARE_DMA_BUFFER_WITH_TS().

2025-05-21iio: make IIO_DMA_MINALIGN minimum of 8 bytesDavid Lechner1-1/+8
Add a condition to ensure that IIO_DMA_MINALIGN is at least 8 bytes. On some 32-bit architectures, IIO_DMA_MINALIGN is 4. In many cases, drivers are using this alignment for buffers that include a 64-bit timestamp that is used with iio_push_to_buffers_with_ts(), which expects the timestamp to be aligned to 8 bytes. To handle this, we can just make IIO_DMA_MINALIGN at least 8 bytes.
