The RK8602 and RK8603 voltage regulators on the Rock 5B board provide
the power lines vdd_cpu_big0 and vdd_cpu_big1, respectively.
Add the necessary device tree nodes and bind them to the corresponding
CPU big core nodes.

Edgeble NCM6A SOM has on-module M.2 1216-compatible WiFi modules.
Currently, AW-XM548NF WiFi6 and Intel 8260D2W WiFi5 modules are supported.
WiFi modules are fixed on SoM, not pluggable M.2 slots, so different SoM's
for each type of WiFi module.

Two pmuio domains on ringneck are not defined:
1- PMUIO1: supplied by vcc_3v3 regulator(PMIC RK809)
2- PMUIO2: supplied by vcc_3v3 regulator(PMIC RK809)
The reason why no functional effect was observed is because of that
the above mentionned PMUIO domains were supplied by a regulator
which is always on.
So let's add their definition in the dtsi.

Add support for the Anbernic RG-ARC S and RG-ARC D devices. These
devices feature the following:
- Rockchip RK3566 SoC
- 4 inch 480x640 display (rotated)
- Goodix multi-touch (ARC D only, untested as I lack the device)
- 1GB (ARC S) or 2GB (ARC D) of RAM
- 2 SDMMC slots
- eMMC (ARC D only)
- Realtek 8821CS WiFi/Bluetooth
- External stereo speakers
- 6 face buttons (A, B, C, X, Y, Z) along with a D-Pad and start and
select buttons.
- A PWM vibrator.
Note that the Goodix touchscreen on I2C2 is not defined, as I lack
the necessary hardware to confirm it works correctly with the mainline
driver.

The "apply this compression method in the background" paths now use the
compression option if background_compression is not set; this means that
setting or changing the compression option will cause existing data to
be compressed accordingly in the background.

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.

Factor out bch2_journal_bufs_to_text(), and use it in the
journal_entry_full() tracepoint; when we can't get a journal reservation
we need to know the outstanding journal entry sizes to know if the
problem is due to excessive flushing.
Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
When issuing discards, we may need to flush the journal if there's too
many buckets that can't be discarded until a journal flush.
But the heuristic was bad; we should be comparing the number of buckets
that need to flushes against the number of free buckets, not the number
of buckets we saw.

Drop t he loop in bch2_kthread_io_clock_wait(): this allows the code
that uses it to be woken up for other reasons, and fixes a bug where
rebalance wouldn't wake up when a scan was requested.
This raises the possibility of spurious wakeups, but callers should
always be able to handle that reasonably well.
