iio: frequency: adf4377: Fix duplicated soft reset mask

2026-03-25T10:08:39+00:00

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: frequency: adf4350: Fix prescaler usage.

2025-10-19T14:33:50+00:00

commit 33d7ecbf69aa7dd4145e3b77962bcb8759eede3d upstream. 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.

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

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

2024-08-03T09:13:45+00:00

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: adf4350: add clk provider

2024-06-25T20:04:49+00:00

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.
