This avoids a build warning due to the use of ACPI_PTR(). Given the driver already has APCI specific code under CONFIG_ACPI move the table rather than removing the ACPI_PTR() call as we already have the complexity of CONFIG_ACPI. Dropped a pointless comma after {} terminator whilst moving the code. Cc: Hans de Goede <hdegoede@redhat.com> Reviewed-by:Hans de Goede <hdegoede@redhat.com> Reviewed-by:

In general using ACPI_PTR() leads to more fragile code for a very minor saving in storage in the case of !CONFIG_ACPI so in IIO we prefer not to use it if the only ACPI specific code is the acpi_device_id table. In this case will also suppress a unused variable warning. Reported-by:

This driver supports 32*3 combinations of fixed ranges and transfer functions, plus custom ranges. So statistically a user has more than 99% chance that the provided default configuration will generate invalid pressure readings if the bindings are not initialized and the driver is instantiated via sysfs. The current patch removes this loophole making sure the driver loads only if the firmware properties are present. Co-developed-by:

Improve driver error resilience by ignoring the measurement if any of the 3 error flags gets set while interacting with the sensor. Based on the datasheet, in table 14 on page 14, the status byte contains: bit 5 busy flag - 1 if device is busy bit 2 memory integrity/error flag - 1 if integrity test failed bit 0 math saturation - 1 if internal math saturation has occurred Co-developed-by: -

Change order of properties in order for the end user to hopefully ignore pmin-pascal and pmax-pascal which are superseded by pressure-triplet. Add pressure-triplet property which automatically initializes pmin-pascal and pmax-pascal inside the driver. Rework honeywell,pmXX-pascal requirements based on feedback from Jonathan and Conor.

da280_match_acpi_device() is a DIY version of acpi_device_get_match_data(), so it can be dropped. And things can be simplified further by using i2c_get_match_data() which will also check i2c_client_id style ids. Signed-off-by:

The AMS AS7331 is a UV light sensor with three channels: UVA, UVB and UVC (also known as deep UV and referenced as DUV in the iio core). Its internal structure and forming blocks are practically identical to the ones the AS73211 contains: API, internal DAC, I2C interface and registers, measurement modes, number of channels and pinout. The only difference between them is the photodiodes used to acquire light, which means that only some modifications are required to add support for the AS7331 in the existing driver. The temperature channel is identical for both devices and only the channel modifiers of the IIO_INTENSITY channels need to account for the device type. The scale values have been obtained from the chapter "7.5 Transfer Function" of the official datasheet[1] for the configuration chosen as basis (Nclk = 1024 and GAIN = 1). Those values keep the units from the datasheet (nW/cm^2), as opposed to the units used for the AS73211 (nW/m^2). Add a new device-specific data structure to account for the device differences: channel types and scale of LSB per channel.

This device has the same properties and I2C addresses as the as73211. The only difference between them is the photodiodes they use internally, which in this case is irrelevant for the bindings. Acked-by:

The scale values associated to the light channels are calculated as a division that can be better expressed as an IIO_VAL_FRACTIONAL type instead of the current IIO_VAL_INT. Note that the constant values used for the calculation were scaled up to work with integers, turning the nW/cm^2 units from the datasheet into nW/m^2, which would not be necessary with the IIO_VAL_FRACTIONAL type. But to avoid issues from current users of the driver, the units must be kept. Signed-off-by:

bcachefs btree nodes are big - typically 256k - and btree roots are pinned in memory. As we're now up to 18 btrees, we now have significant memory overhead in mostly empty btree roots. And in the future we're going to start enforcing that certain btree node boundaries exist, to solve lock contention issues - analagous to XFS's AGIs. Thus, we need to start allocating smaller btree node buffers when we can. This patch changes code that refers to the filesystem constant c->opts.btree_node_size to refer to the btree node buffer size - btree_buf_bytes() - where appropriate. Signed-off-by:
