The binary content of nvmem devices is available to the user so in the
easiest cases, finding the content of a cell is rather easy as it is
just a matter of looking at a known and fixed offset. However, nvmem
layouts have been recently introduced to cope with more advanced
situations, where the offset and size of the cells is not known in
advance or is dynamic. When using layouts, more advanced parsers are
used by the kernel in order to give direct access to the content of each
cell regardless of their position/size in the underlying device, but
these information were not accessible to the user.
By exposing the nvmem cells to the user through a dedicated cell/ folder
containing one file per cell, we provide a straightforward access to
useful user information without the need for re-writing a userland
parser. Content of nvmem cells is usually: product names, manufacturing
date, MAC addresses, etc,

Pull ARM SoC fixes from Arnd Bergmann:
"Most of the changes are devicetree fixes for NXP, Mediatek, Rockchips

build-time warnings for spec violations and other minor issues. One of
the Mediatek warnings was enabled by default and prevented a clean
build.
The ones that address serious runtime issues are all on the i.MX
platform:
- a boot time panic on imx8qm
- USB hanging under load on imx8
- regressions on the imx93 ethernet phy
Code fixes include a minor error handling for the i.MX PMU driver, and
a number of firmware driver fixes:
- OP-TEE fix for supplicant based device enumeration, and a new sysfs
attribute to needed to fix a race against userspace
- Arm SCMI fix for possible truncation/overflow in the frequency

There has been more than a few threads which went idle before
the merge window and now people came back to them and started
asking about next steps.
We currently tell people to be patient and not to repost too
often. Our "not too often", however, is still a few orders of
magnitude faster than other subsystems. Or so I feel after
hearing people talk about review rates at LPC.
Clarify in the doc that if the discussion went idle for a week
on netdev, 95% of the time there's no point waiting longer.

The sd fix is so large because it changes a struct pointer to a struct
but otherwise is fairly simple"

n(n<7) TPR registers to configure value for timestamp request
based on input pattern match. Eight 32 bit registers providing
DSB interface timestamp request pattern match comparison. And

Add the nodes to set value for DSB edge control and DSB edge
control mask. Each DSB subunit TPDM has maximum of n(n<16) EDCR
resgisters to configure edge control. DSB edge detection control
00: Rising edge detection

edge detection mask control.
Add the nodes to configure DSB edge control and DSB edge control
mask. Each DSB subunit TPDM maximum of 256 edge detections can be
configured. The index and value sysfs files need to be paired and
written to order. The index sysfs file is to set the index number
of the edge detection which needs to be configured. And the value
sysfs file is to set the control or mask for the edge detection.
DSB edge detection control should be set as the following values.
00: Rising edge detection
01: Falling edge detection
10: Rising and falling edge detection (toggle detection)
And DSB edge mask should be set as 0 or 1.
Each DSB subunit TPDM has maximum of n(n<16) EDCR resgisters to
configure edge control. And each DSB subunit TPDM has maximum of
m(m<8) ECDMR registers to configure mask.
Add the nodes to read a set of the edge control value and mask
of the DSB in TPDM.

Currently TMC-ETR automatically selects the buffer mode from all available
methods in the following sequentially fallback manner - also in that order.
1. FLAT mode with or without IOMMU
2. TMC-ETR-SG (scatter gather) mode when available
3. CATU mode when available
But this order might not be ideal for all situations. For example if there
is a CATU connected to ETR, it may be better to use TMC-ETR scatter gather
method, rather than CATU. But hard coding such order changes will prevent
us from testing or using a particular mode. This change provides following
new sysfs tunables for the user to control TMC-ETR buffer mode explicitly,
if required. This adds following new sysfs files for buffer mode selection
purpose explicitly in the user space.
/sys/bus/coresight/devices/tmc_etr<N>/buf_modes_available
/sys/bus/coresight/devices/tmc_etr<N>/buf_mode_preferred
$ cat buf_modes_available
auto flat tmc-sg catu ------------------> Supported TMC-ETR buffer modes
$ echo catu > buf_mode_preferred -------> Explicit buffer mode request
But explicit user request has to be within supported ETR buffer modes only.
These sysfs interface files are exclussive to ETR, and hence these are not
available for other TMC devices such as ETB or ETF etc.
A new auto' mode (i.e ETR_MODE_AUTO) has been added to help fallback to the
existing default behaviour, when user provided preferred buffer mode fails.
ETR_MODE_FLAT and ETR_MODE_AUTO are always available as preferred modes.
