For SD host controller version 4.00 or later ones, there're two
modes of implementation - Version 3.00 compatible mode or
Version 4 mode. This patch introduced an interface to enable

ADMA2 64-bit addressing support is divided into V3 mode and V4 mode.
So there are two kinds of descriptors for ADMA2 64-bit addressing
i.e. 96-bit Descriptor for V3 mode, and 128-bit Descriptor for V4

For V4 mode, ADMA2 64-bit addressing is enabled vi
As SD Host Controller Specification v4.10 documents:
Host Controller Version 4.10 defines this "Auto CMD Auto Select" mode.
Selection of Auto CMD depends on setting of CMD23 Enable in the Host
Control 2 register which indicates whether card supports CMD23. If CMD23
Enable =1, Auto CMD23 is used and
Host Controller Version 4.10 re-defines SDMA System Address register
as 32-bit Block Count for v4 mode, and SDMA uses ADMA System
Address register (05Fh-058h) instead if v4 mode is enabled. Also
when using 32-bit block count, 16-bit block count register need
to be set to zero.

According to the SD host controller specification version 4.10, when

R11 is a variant based on SD v4.0 specification.

The headset device will use channel 20 of ADC controller to detect events,
but it needs the raw ADC data to do conversion according to its own formula.
Thus we should configure the channel mask separately and configure channel
20 as IIO_CHAN_INFO_RAW, as well as adding raw data read support.
Sign
This patch adds support to read calibration values from the eFuse
controller to calibrate the ADC channel scales, which can make ADC
sample data more accurate.

Hi folks,
ARM have some upcoming CPU features that are similar to Intel RDT. Resctrl
is the defacto ABI for this sort of thing, but it lives under arch/x86.
To get existing software working, we need to make resctrl work with arm64.
This series is the first chunk of that. The aim is to move the fi
Now that the closid is present in the staged configuration,
update_domains() can learn which low/high values it should update.
Remove the single passed in closid, and update msr_param as we
apply each staged config.

num_closid is different for the illusionary CODE/DATA caches, and
these resource's ctrlval is sized on this parameter. When it comes
to writing the configuration values into hardware, a correction is
applied.
The next step in moving this behaviour into the resctrl code is
to make the arch code alw
Today we switch between different alloc_enabled resources which
have differing preset num_closid to account for CDP.
We want to merge these illusionary caches together, at which
point something needs to change the resctrl's view of num_closid.
The arch code now has its own idea of how many closids
Now that CDP enable/disable is global, and the closid offset correction
is based on the configuration being applied, we can use the same
Lx resource twice for CDP's CODE/DATA schema. This keeps the illusion
of separate caches in the resctrl code.
When CDP is enabled for a cache, create two schema
Move the names used for the schemata file out of the resource and
into struct resctrl_schema. This lets us give one resource two
different names, based on the other schema properties.
For now we copy the name, once we merge the L2/L2CODE/L2DATA
resources resctrl will generate it.
Remove the arch
Now that resctrl has a list of resources it is using, walk that list
instead of the architectures list. This lets us keep schema properties
with the resource that is using them.

Once we merge the L2/L2CODE/L2DATA resources, we still want to have

These two configurations would have different closid as far as the
