When adding more than one IIO buffer per IIO device, we will need to create
a buffer & scan_elements directory for each buffer.
We also want to move the 'scan_elements' to be a sub-directory of the
'buffer' folder.
The format we want to reach is, for a iio:device0 folder, for 2 buffers
[for exampl
This change makes it so that the first buffer directory is named 'buffer0'
and moves the 'scan_elements' under it.
For backwards compatibility these folders are symlinked back to the
original folders.

The __iio_device_attr_init() function initializes a device_attribute

We will want to re-use this logic for name-creation, so this change

Updates to the cpupower command to add support for AMD family 0x19
and cleanup the code to remove many of the family checks to hopefully
make any future family updates easier.
The first couple of patches are simple updates to rename the structs
in the msr_pstate union to better reflect current sup
The msr_pstate union struct named fam17h_bits is misleading since
this is the struct to use for all families >= 0x17, not just
for family 0x17. Rename the bits structs to be 'pstate' (for pre
family 17h CPUs) and 'pstatedef' (for CPUs since fam 17h) to align
closer with PPR/BDKG naming.

Add a check in get_cpu_info() for the ability to read frequencies
from hardware and set the CPUPOWER_CAP_AMD_HW_PSTATE cpuid flag.
The cpuid flag is set when CPUID_8007_EDX[7] is set,
which is all families >= 10h. The check excludes family 14h
because HW pstate reporting was not implemented on
The family checks in get_cof() and get_did() need to use the
correct MSR format depending on the family. Add a cpupower
capability for using the pstatedef (family 17h and newer) to
control this instead of direct family checks.

Define fwnode_phy_find_device() to iterate an mdiobus and find the
phy device of the provided phy fwnode. Additionally define
device_phy_find_device() to find phy device of provided device.
Define fwnode_get_phy_node() to get phy_node using named reference.

commit 4d163ad79b155c71bf30366dc38f8d2502f78844 upstream.
The issue is that using SPI from a callback under the CCF lock will
deadlock, since this code uses clk_get_rate().

Since the original mtu is not used when the mtu is updated,
the mtu is aligned with cache, this will get an incorrect.
For example, if you want to configure the mtu to be 1500,

BFQ heuristics try to detect interactive I/O, and raise the weight of

associated with that queue), then it is most likely better to prevent
