2026-03-14iio: frequency: admv1013: fix NULL pointer dereference on strAntoniu Miclaus
When device_property_read_string() fails, str is left uninitialized but the code falls through to strcmp(str, ...), dereferencing a garbage pointer. Replace manual read/strcmp with device_property_match_property_string() and consolidate the SE mode enums into a single sequential enum, mapping to hardware register values via a switch consistent with other bitfields in the driver. Several cleanup patches have been applied to this driver recently so this will need a manual backport.

2026-02-23iio: frequency: adf4377: Fix duplicated soft reset maskSeungJu Cheon
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.

2025-08-31iio: frequency: adf4350: Fix prescaler usage.Michael Hennerich
The ADF4350/1 features a programmable dual-modulus prescaler of 4/5 or 8/9. When set to 4/5, the maximum RF frequency allowed is 3 GHz. Therefore, when operating the ADF4351 above 3 GHz, this must be set to 8/9. In this context not the RF output frequency is meant - it's the VCO frequency. Therefore move the prescaler selection after we derived the VCO frequency from the desired RF output frequency. This BUG may have caused PLL lock instabilities when operating the VCO at the very high range close to 4.4 GHz.

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.

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

2024-08-03iio: frequency: adf4377: add adf4378 supportAntoniu Miclaus
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.

2024-06-25iio: frequency: adf4350: add clk providerAntoniu Miclaus
Add clk provider feature for the adf4350. Even though the driver was sent as an IIO driver in most cases the device is actually seen as a clock provider. This patch aims to cover actual usecases requested by users in order to completely control the output frequencies from userspace.

We can reduce boilerplate code by using devm_regulator_get_enable_read_voltage(). The common mode voltage is now passed as a parameter in the init functions so we can avoid adding a state member that is only used during init.
