c2cf7e25eb mtd: rawnand: brcmnand: Add support for getting ecc setting from strap 
BCMBCA broadband SoC based board design does not specify ecc setting in
dts but rather use the SoC NAND strap info to obtain the ecc strength
and spare area size setting. Add brcm,nand-ecc-use-strap dts propety for
this purpose and update driver to support this option. However these two
options can not be used at the same time.

1c60e027ff mtd: nand: raw: atmel: Fix comment in timings preparation 
Looks like a copy'n'paste mistake introduced when initially adding the
dynamic timings feature with commit f9ce2eddf1 ("mtd: nand: atmel: Add
->setup_data_interface() hooks").  The context around this and
especially the code itself suggests 'read' is meant instead of write.

6fb075fca6 mtd: rawnand: Ensure all continuous terms are always in sync 
While crossing a LUN boundary, it is probably safer (and clearer) to
keep all members of the continuous read structure aligned, including the
pause page (which is the last page of the lun or the last page of the
continuous read). Once these members properly in sync, we can use the
rawnand_cap_cont_reads() helper everywhere to "prepare" the next
continuous read if there is one.

e395036504 mtd: rawnand: Prefer struct_size over open coded arithmetic 
This is an effort to get rid of all multiplications from allocation
functions in order to prevent integer overflows [1].

As the "chip" variable is a pointer to "struct mtk_nfc_nand_chip" and
this structure ends in a flexible array:

struct mtk_nfc_nand_chip {
	[...]
	u8 sels[] __counted_by(nsels);
};

the preferred way in the kernel is to use the struct_size() helper to
do the arithmetic instead of the argument "size + count * size" in the
devm_kzalloc() function.

This way, the code is more readable and safer.

According to the datasheets, the ESMT chips in question will return a 5
byte long identification code where the last 3 bytes are the JEDEC
continuation codes (7Fh). Although, I would have expected 4 continuation
codes as Powerchip Semiconductor (C8h, corresponding to the parameter
page data) is located in bank 5 of the JEDEC database.

By matching the full 5 bytes we can avoid clashes with GigaDevice NAND
flashes.

This fix allows the MT7688-based GARDENA smart Gateway to boot again.

E.g. ESMT chips will return an identification code with a length of 5
bytes. In order to prevent ambiguity, flash chips would actually need to
return IDs that are up to 17 or more bytes long due to JEDEC's
continuation scheme. I understand that if a manufacturer ID is located
in bank N of JEDEC's database (there are currently 16 banks), N - 1
continuation codes (7Fh) need to be added to the identification code
(comprising of manufacturer ID and device ID). However, most flash chip
manufacturers don't seem to implement this (correctly).

fsl_lbc driver didn't bind yet. So return -EPROBE_DEFER in this case to
make the driver core retry probing later.

Pull more bcachefs updates from Kent Overstreet:
 "Some fixes, Some refactoring, some minor features:

   - Assorted prep work for disk space accounting rewrite

   - BTREE_TRIGGER_ATOMIC: after combining our trigger callbacks, this
     makes our trigger context more explicit

   - A few fixes to avoid excessive transaction restarts on
     multithreaded workloads: fstests (in addition to ktest tests) are
     now checking slowpath counters, and that's shaking out a few bugs

   - Assorted tracepoint improvements

   - Starting to break up bcachefs_format.h and move on disk types so
     they're with the code they belong to; this will make room to start
     documenting the on disk format better.

   - A few minor fixes"

Pull timer updates from Thomas Gleixner:
 "Updates for time and clocksources:

   - A fix for the idle and iowait time accounting vs CPU hotplug.

     The time is reset on CPU hotplug which makes the accumulated
     systemwide time jump backwards.

   - Assorted fixes and improvements for clocksource/event drivers"
