[PATCH v2 0/3] iio: flow: Sensirion SLF3S liquid flow sensor

[Wadim Mueller <wafgo01@gmail.com>]

Hi all,

v2 addresses the inline review feedback from Jonathan and Guenter on v1
(see https://lore.kernel.org/linux-iio/20260524205112.26638-1-wafgo01@gmail.com/).
Per-patch replies have been sent in the v1 thread.

The series is dropped from RFC: subsystem placement (iio/flow/),
channel type (IIO_VOLUMEFLOW) and the new subdirectory have all been
ACKed in v1.

Changes since v1:

  * rename driver/binding from slf3x to slf3s (Jonathan -- the
    marketing family name is SLF3S)
  * fold MAINTAINERS entry into the dt-binding patch instead of a
    separate 4/4 patch (Jonathan)
  * add SLF3S-1300F support (Guenter)
  * dt-binding: split the single "sensirion,slf3s" compatible into
    per-variant compatibles (-0600F, -1300F, -4000B) with a generic
    fallback (Jonathan)
  * dt-binding: add optional interrupts property (Guenter -- bindings
    describe the hardware, not the current driver)
  * driver: seed the variant from DT via i2c_get_match_data() instead
    of probing the sensor first (Jonathan)
  * driver: detect_variant() now trusts the DT-supplied variant and
    only emits dev_dbg() on a sub_type/family mismatch (Jonathan)
  * driver: per-instance crc8_populate_msb() rather than a global
    crc table (Jonathan)
  * driver: declare cmd as const u8 [static 2] in slf3s_send_cmd()
    (Jonathan)
  * driver: switch to fsleep() and sign_extend32() helpers (Jonathan)
  * driver: use named initialisers for slf3s_variants[] entries
    (Jonathan)
  * driver: unsigned int loop counters (Jonathan)
  * Kconfig: tab-indented bulleted list of supported parts (Jonathan)
  * ABI sysfs doc: _scale entry folded into the shared block,
    _raw block kept with its own KernelVersion (Guenter)
  * re-checked all scale factors against the SLF3S datasheets
    (Table 16 for -0600F, Table 15 for -1300F and -4000B)

Patches:

  1/3  iio: types: add IIO_VOLUMEFLOW channel type
  2/3  dt-bindings: iio: flow: add sensirion,slf3s binding
  3/3  iio: flow: add Sensirion SLF3S liquid flow sensor driver

Tested with an SLF3S-0600F on a TI AM64x platform; W=1 build clean,
checkpatch --strict clean, dt_binding_check clean.

Thanks,
Wadim
