gcc 10 will default to -fno-common, which causes this error at link
time:
(.text+0x0): multiple definition of `yylloc'; dtc-lexer.lex.o (symbol from plugin):(.text+0x0): first defined here
This is because both dtc-lexer as well as dtc-parser define the same
global symbol yyloc. Before with -fcommon those were merged into one
defintion. The proper solution would be to to mark this as "extern",
however that leads to:
dtc-lexer.l:26:16: error: redundant redeclaration of 'yylloc' [-Werror=redundant-decls]

cc1: all warnings being treated as errors
which means the declaration is completely redundant and can just be

Add MIPI DSI pipeline for Allwinner A64.
- dsi node, with A64 compatible since it doesn't support
DSI_SCLK gating unlike A33
- dphy node, with A64 compatible with A33 fallback since
DPHY on A64 and A33 is similar
- finally, attach the dsi_in to tcon0 for complete MIPI DSI

Usage of clocks are varies between different Allwinner
DSI controllers. Clocking in A33 would need bus and
mod clocks where as A64 would need only bus clock.
To support this kind of clocking structure variants
in the same dsi driver, explicit handling of common
clock would require since the A64 doesn't need to
mention the clock-names explicitly in dts since it
support only one bus clock.
Also pass clk_id NULL instead "bus" to regmap clock
init function since the single clock variants no need
to mention clock-names explicitly.

As per the user manual, look like mod clock is not mandatory
for all Allwinner MIPI DSI controllers, it is connected to
CLK_DSI_SCLK for A31 and not available in A64.
So add has_mod_clk quirk and process the mod clk accordingly.

The MIPI DSI controller in Allwinner A64 is similar to A33.
But unlike A33, A64 doesn't have DSI_SCLK gating so it is valid
to have separate compatible for A64 on the same driver.
DSI_SCLK uses mod clock-names on dt-bindings, so the same
is not required for A64.
On that note
- A64 require minimum of 1 clock like the bus clock
- A33 require minimum of 2 clocks like both bus, mod clocks
So, update dt-bindings so-that it can document both A33,
A64 bindings requirements.

If we're sharing the ring across forks, then one process exiting means
that we cancel ALL work and prevent future work. This is overly
restrictive. As long as we cancel the work associated with the files
from the current task, it's safe to let others persist. Normal fd close
on exit will still wait (and cancel) pending work.

Host-aware SMR drives can be used with the commands to explicitly manage
zone state, but they can also be used as normal disks. In the former
case it makes perfect sense to allow partitions on them, in the latter
it does not, just like for host managed devices. Add a check to
add_partition to allow partitions on host aware devices, but give
up any zone management capabilities in that case, which also catches
the previously missed case of adding a partition vs just scanning it.
Because sd can rescan the attribute at runtime it needs to check if
a disk has partitions, for which a new helper is added to genhd.h.

The afs filesystem needs to prohibit certain characters from cell names,

Fix afs_alloc_cell() to disallow nonprintable characters, '/', '@' and
names that begin with a dot.
Remove the check for "@cell" as that is then redundant.
This can be tested by running:
echo add foo/.bar 1.2.3.4 >/proc/fs/afs/cells
Note that we will also need to deal with:
- Names ending in ".invalid" shouldn't be passed to the DNS.
- Names that contain non-valid domainname chars shouldn't be passed to
the DNS.
- DNS replies that say "your-dns-needs-immediate-attention.<gTLD>" and
replies containing A records that say 127.0.53.53 should be
considered invalid.
