iio: frequency: adf4377: Fix duplicated soft reset mask

2026-03-19T15:15:29Z

commit 6c8bf4b604a8a6346ca71f1c027fa01c2c2e04cb upstream. The regmap_read_poll_timeout() uses ADF4377_0000_SOFT_RESET_R_MSK twice instead of checking both SOFT_RESET_MSK (bit 0) and SOFT_RESET_R_MSK (bit 7). This causes an incomplete reset status check. The code first sets both SOFT_RESET and SOFT_RESET_R bits to 1 via regmap_update_bits(), then polls for them to be cleared. Since we set both bits before polling, we should be waiting for both to clear. Fix by using both masks as done in regmap_update_bits() above.

iio: normalize array sentinel style

2025-04-22T18:10:04Z

Use `\t(\{ ?\},|\{\}|\{\s*/\*.*\*/\s*\},?)$` regex to find and replace the array sentinel in all IIO drivers to the same style. For some time, we've been trying to consistently use `{ }` (no trailing comma, no comment, one space between braces) for array sentinels in the IIO subsystem. Still nearly 50% of existing code uses a different style. To save reviewers from having to request this trivial change as frequently, let's normalize the style in all existing IIO drivers. At least when code is copy/pasted to new drivers, the style will be consistent.

move asm/unaligned.h to linux/unaligned.h

2024-10-02T21:23:23Z

asm/unaligned.h is always an include of asm-generic/unaligned.h; might as well move that thing to linux/unaligned.h and include that - there's nothing arch-specific in that header. auto-generated by the following: for i in `git grep -l -w asm/unaligned.h`; do sed -i -e "s/asm\/unaligned.h/linux\/unaligned.h/" $i done for i in `git grep -l -w asm-generic/unaligned.h`; do sed -i -e "s/asm-generic\/unaligned.h/linux\/unaligned.h/" $i done git mv include/asm-generic/unaligned.h include/linux/unaligned.h git mv tools/include/asm-generic/unaligned.h tools/include/linux/unaligned.h sed -i -e "/unaligned.h/d" include/asm-generic/Kbuild sed -i -e "s/__ASM_GENERIC/__LINUX/" include/linux/unaligned.h tools/include/linux/unaligned.h

iio: frequency: adf4377: add adf4378 support

2024-08-03T09:13:45Z

Add separate handling for adf4378 within the driver. The main difference between adf4377 and adf4378 is that adf4378 has only one output which is handled by only one gpio.

iio: frequency: adf4377: add support for ADF4377

2022-11-23T21:05:51Z

The ADF4377 is a high performance, ultralow jitter, dual output integer-N phased locked loop (PLL) with integrated voltage controlled oscillator (VCO) ideally suited for data converter and mixed signal front end (MxFE) clock applications.
