Since commit 8208181fe536 ("clk: imx: composite-8m:

arm64: dts: imx8mn: Slow default video_pll clock rate

Since commit 8208181fe536 ("clk: imx: composite-8m:
Add imx8m_divider_determine_rate") the lcdif controller has
had the ability to set the disp_pixel_clk rate which propagates
up the tree and sets the video_pll rate automatically.

By setting this value low, it will force the recalculation of
video_pll to the lowest rate needed by lcdif instead of
dividing a larger clock down to the desired clock speed. This
has the  advantage of being able to lower the video_pll rate
from 594MHz to 148.5MHz when operating at 1080p. It can go even
lower when operating at lower resolutions and refresh rates.

The SGTL5000 is attached to SAI3, however the SGTL5000 codec MCLK

To provide such flexible MCLK control, use PWM4 with period 1 and

to route MX8MP CCM clock to the MCLK pin. Use codec as bitclock

arm64: dts: imx: add imx8dxp support

i.MX 8DualXPlus is a dual (2x) Cortex-A35 processor with powerful
graphic and multimedia features. This patch adds the SoC dtsi, based on
imx8qxp removing the additional CPU cores. Peripherals are identical.

arm64: dts: imx8mm-kontron: Refactor devicetree for OSM-S module and board

The OSM spec defines dedicated functions for all pads of the SoM.
Therefore we can assume that carrier board designs stick to these
definitions and extend the SoM devicetree include with matching
default nodes and pinmux settings.

This way we can reduce the overhead and redundancy in the carrier
board devicetrees while still sticking to the policy of separating
board and module description.

Even if the carrier board design deviates slightly from the spec it
can define its own pinmux definitions and use them as necessary or
even disable unused nodes from the SoM devicetree.

The current state of the devicetree for the i.MX8MM OSM-S and the BL

bcachefs: Prep work for variable size btree node buffers

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.

======================================================

In __bch2_ioctl_subvolume_create(), we grab s_umount unconditionally
and unlock it at the end of the function. There is a comment
"why do we need this lock?" about the lock coming from
commit 42d237320e98 ("bcachefs: Snapshot creation, deletion")
The reason is that __bch2_ioctl_subvolume_create() calls
sync_inodes_sb() which enforce locked s_umount to writeback all dirty
nodes before doing snapshot works.

Fix it by read locking s_umount for snapshotting only and unlocking
s_umount after sync_inodes_sb().
