a6a355ede5 arm64: dts: imx8mm-evk: Add 32.768 kHz clock to PMIC
The ROHM BD71847 PMIC has a 32.768 kHz clock.  Adding necessary parent
allows to probe the bd718x7 clock driver fixing boot errors:

    bd718xx-clk bd71847-clk.1.auto: No parent clk found
    bd718xx-clk: probe of bd71847-clk.1.auto failed with error -22

Device tree schema expects pin configuration groups to end with 'grp'
suffix.  This fixes dtbs_check warnings like:

    do not match any of the regexes: 'grp$', 'pinctrl-[0-9]+'

aa71d06483 arm64: dts: imx8mm: Split the imx8mm evk board dts to a common dtsi
There are two type of i.MX8MM EVK board, one is populated with
LPDDR4(default dts), and one is populated with DDR4. these two
boards share most of the board design, but still have some difference.
imx8mm-evk has emmc support, imx8mm-ddr4-evk has gpmi nand support.
And also, the BT/WIFI module is different. So move the common dts
part into imx8mm-evk.dtsi for reuse.

The PMIC node can be a clock provider (for its 32 kHz clock) and authors

f2dc2359b7 arm64: dts: freescale: Fix SP805 clock-names
The SP805 binding sets the order of the clock-names to be: "wdog_clk",
"apb_pclk" (in exactly that order).

Change the order in the DTs for Freescale platforms to match that. The
two clocks given in all nodes are actually the same, so that does not
change any behaviour.

843b993c2d arm64: dts: imx8m: Fix the SPI chipselect polarity
The conversion of the spi-imx driver to use GPIO descriptors
in commit 8cdcd8aeee ("spi: imx/fsl-lpspi: Convert to GPIO descriptors")
helped to detect the following SPI chipselect polarity mismatch on an
imx6q-sabresd for example:

[    4.854337] m25p80@0 enforce active low on chipselect handle

Prior to the above commit, the chipselect polarity passed via cs-gpios
property was ignored and considered active-low.

The reason for such mismatch is clearly explained in the comments inside
drivers/gpio/gpiolib-of.c:

 * SPI children have active low chip selects
 * by default. This can be specified negatively
 * by just omitting "spi-cs-high" in the
 * device node, or actively by tagging on
 * GPIO_ACTIVE_LOW as flag in the device
 * tree. If the line is simultaneously
 * tagged as active low in the device tree
 * and has the "spi-cs-high" set, we get a
 * conflict and the "spi-cs-high" flag will
 * take precedence.

To properly represent the SPI chipselect polarity, change it to active-low
when the "spi-cs-high" property is absent.

	"Birch"		r1	supported by r2
	"Chestnut"	r2	added by this patch

f91daf565b io_uring: short circuit -EAGAIN for blocking read attempt
One case was missed in the short IO retry handling, and that's hitting
-EAGAIN on a blocking attempt read (eg from io-wq context). This is a
problem on sockets that are marked as non-blocking when created, they
don't carry any REQ_F_NOWAIT information to help us terminate them
instead of perpetually retrying.

d4e7cd36a9 io_uring: sanitize double poll handling
There's a bit of confusion on the matching pairs of poll vs double poll,
depending on if the request is a pure poll (IORING_OP_POLL_ADD) or
poll driven retry.

Add io_poll_get_double() that returns the double poll waitqueue, if any,
and io_poll_get_single() that returns the original poll waitqueue. With
that, remove the argument to io_poll_remove_double().

Finally ensure that wait->private is cleared once the double poll handler
has run, so that remove knows it's already been seen.

Pull more perf tools updates from Arnaldo Carvalho de Melo:
 "Fixes:
   - Fixes for 'perf bench numa'.

   - Always memset source before memcpy in 'perf bench mem'.

   - Quote CC and CXX for their arguments to fix build in environments
     using those variables to pass more than just the compiler names.

   - Fix module symbol processing, addressing regression detected via
     "perf test".

   - Allow multiple probes in record+script_probe_vfs_getname.sh 'perf
     test' entry.

  Improvements:
   - Add script to autogenerate socket family name id->string table from
     copy of kernel header, used so far in 'perf trace'.

   - 'perf ftrace' improvements to provide similar options for this
     utility so that one can go from 'perf record', 'perf trace', etc to
     'perf ftrace' just by changing the name of the subcommand.

   - Prefer new "sched:sched_waking" trace event when it exists in 'perf
     sched' post processing.

   - Update POWER9 metrics to utilize other metrics.

   - Fall back to querying debuginfod if debuginfo not found locally.

  Miscellaneous:
   - Sync various kvm headers with kernel sources"
