So far we used an internal linux-imx@nxp.com email address to
gather all patches related to NXP i.MX development.
Let's switch to an open mailing list that provides ability
for people from the community to subscribe and also have
a proper archive.

This fixes the display not working on colibri imx7, the driver fails to
load with the following error:
mxsfb 30730000.lcdif: error -ENODEV: Cannot connect bridge
NXP i.MX7 LCDIF is connected to both the Parallel LCD Display and to a
MIPI DSI IP block, currently it's not possible to describe the
connection to both.
Remove the port endpoint from the SOC dtsi to prevent regressions, this
would need to be defined on the board DTS.

Since commit bfac19e239 ("fbdev: mx3fb: Remove the driver") backlight
is no longer functional.
The fbdev mx3fb driver used to automatically select
CONFIG_BACKLIGHT_CLASS_DEVICE.
Now that the mx3fb driver has been removed, enable the
CONFIG_BACKLIGHT_CLASS_DEVICE option so that backlight can still work
by default.
Tested on a imx6dl-sabresd board.

When the range parsing was open-coded the number of u32 entries to
parse had to be a multiple of 4 and the driver checks this. With
the range parsing converted to the range parser the counting changes
from individual u32 entries to a complete range, so the check must
not reject counts not divisible by 4.

UART4 is used as CM7 coprocessor debug UART and may not be accessible from

platform firmware. UART4 is not used on this platform by Linux. Disable

is in place.

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.

drop_locks_do() should not be used in a fastpath without first trying

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.

Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
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.
