These devices are designed for implementing local oscillators (LOs) in high-frequency applications. The ADF41513 covers frequencies from 1 GHz to 26.5 GHz, while the ADF41510 operates from 1 GHz to 10 GHz. Key features supported by this driver: - Integer-N and fractional-N operation modes - High maximum PFD frequency (250 MHz integer-N, 125 MHz fractional-N) - 25-bit fixed modulus or 49-bit variable modulus fractional modes - Digital lock detect functionality - Phase resync capability for consistent output phase - Load Enable vs Reference signal syncronization The series includes: 1. PLL driver implementation 2. Device tree bindings documentation 3. IIO ABI documentation Signed-off-by: Rodrigo Alencar --- Changes in v5: - Drop local parsing of 64-bit plus fractional parts - Add iio_str_to_fixpoint64() to iio core with parsing tests - Add DT property dependency for adi,charge-pump-resistor-ohms - Add local definition for ADF41513_HZ_PER_GHZ and drop units.h patch - Link to v4: https://lore.kernel.org/r/20260116-adf41513-iio-driver-v4-0-dbb7d6782217@analog.com Changes in v4: - Proper usage of units.h macros - Simplifications to DT property parsing - Adjustments to return value handling - Drop of simple DT property node example - Link to v3: https://lore.kernel.org/r/20260108-adf41513-iio-driver-v3-0-23d1371aef48@analog.com Changes in v3: - Use FIELD_MODIFY macro in driver implementation - Drop refin_frequency iio attribute - Drop muxout-select property from dt-bindings (and rename logic-level property) - Use -mhz suffix in power-up frequency property - Address documentation issues - Link to v2: https://lore.kernel.org/r/20251219-adf41513-iio-driver-v2-0-be29a83d5793@analog.com Changes in v2: - separate driver implementation from extra features and improve commit messages - use macros from units.h - explanation of custom parse function: adf41513_parse_uhz - reorganize driver data structures - drop clock framework support for now - reorganize documentation - Link to v1: https://lore.kernel.org/r/20251110-adf41513-iio-driver-v1-0-2df8be0fdc6e@analog.com --- Rodrigo Alencar (8): dt-bindings: iio: frequency: add adf41513 iio: core: add fixed point parsing with 64-bit parts iio: test: add kunit test for fixed-point parsing iio: frequency: adf41513: driver implementation iio: frequency: adf41513: handle LE synchronization feature iio: frequency: adf41513: features on frequency change docs: iio: add documentation for adf41513 driver Documentation: ABI: testing: add common ABI file for iio/frequency Documentation/ABI/testing/sysfs-bus-iio-frequency | 11 + .../bindings/iio/frequency/adi,adf41513.yaml | 215 ++++ Documentation/iio/adf41513.rst | 199 ++++ Documentation/iio/index.rst | 1 + MAINTAINERS | 11 + drivers/iio/frequency/Kconfig | 10 + drivers/iio/frequency/Makefile | 1 + drivers/iio/frequency/adf41513.c | 1244 ++++++++++++++++++++ drivers/iio/industrialio-core.c | 151 ++- drivers/iio/test/Kconfig | 12 + drivers/iio/test/Makefile | 1 + drivers/iio/test/iio-test-fixpoint-parse.c | 437 +++++++ include/linux/iio/iio.h | 2 + 13 files changed, 2245 insertions(+), 50 deletions(-) --- base-commit: c30e80d68a7afb334fde7147ee0106f25dd58d3a change-id: 20251110-adf41513-iio-driver-aaca8a7f808e Best regards, -- Rodrigo Alencar
