48b77cdca5 leds: ns2: remove unneeded variable
No need to use variable found, we can determine whether the mode was
found by comparing iterator variable to its limit.

01d0b14d0e leds: ns2: support OF probing only, forget platdata
Move forward from platform data to device tree only.

Since commit c7896490dd ("leds: ns2: Absorb platform data") the
platform data structure is absorbed into the driver, because nothing
else in the source tree uses it. Since nobody complained and all usage
of this driver is via device tree, change the code to work with device
tree only. As Linus Walleij wrote, the device tree should be the
preferred way forward anyway.

de73f275a0 leds: pwm: Allow automatic labels for DT based devices
If LEDs are configured through device tree and the property 'label' is
omitted, the label is supposed to be generated from the properties
'function' and 'color' if present.  While this works fine for e.g. the
'leds-gpio' driver, it did not for 'leds-pwm'.

The reason is, you get this label naming magic only if you add a LED
device through 'devm_led_classdev_register_ext()' and pass a pointer to
the current device tree node.

For the following node from dts the LED appeared as 'led-5' in sysfs
before and as 'red:debug' after this change.

        pwm_leds {
                compatible = "pwm-leds";

                led-5 {
                        function = LED_FUNCTION_DEBUG;
                        color = <LED_COLOR_ID_RED>;
                        pwms = <&pwm0 2 10000000 0>;
                        max-brightness = <127>;

                        linux,default-trigger = "heartbeat";

drm/ingenic: Add support for 30-bit modes
Starting from the JZ4760 SoC, the primary and overlay planes support
30-bit pixel modes (10 bits per color component). Add support for these
in the ingenic-drm driver.

drm/ingenic: Support handling different pixel formats in F0/F1 planes
Until now the ingenic-drm driver supported the same pixel formats on the
F0 and F1 planes, and across all SoCs. However, the F0 plane does support
paletted 8bpp, while the F1 plane doesn't.

Furthermore, the three SoCs currently supported all have different pixel
formats available; 24bpp was added in JZ4725B, 30bpp was added in
JZ4770.

Prepare the inclusion of paletted 8bpp, 24bpp and 30bpp support by
having separate pixel format lists for F0 and F1 planes.

drm/ingenic: Alloc F0 and F1 DMA descriptors at once
Instead of calling dmam_alloc_coherent() once for each 4-bit DMA
hardware descriptor, we can have them both in a physical memory page, as
long as they are aligned to 16 bytes. This reduces memory consumption,
and will make it easier to add more DMA descriptors in the future.

Note that the old code would not create the F0 descriptor on SoCs that
don't support multiple planes. We don't care, because:
- we don't use more memory by allocating two descriptors instead of a
  single one;
- the only SoC that does not support multiple planes (JZ4740) still has
  two independent DMA channels, for an unknown reason.

drm/ingenic: Add support for reserved memory
Add support for static memory reserved from Device Tree. Since we're
using GEM buffers backed by CMA, it is interesting to have an option to
specify the CMA area where the GEM buffers will be allocated.

v2: Don't abort probe if reserved memory cannot be obtained. The driver
    will still work fine provided the kernel configuration is sane.

drm/ingenic: Reset pixclock rate when parent clock rate changes
Old Ingenic SoCs can overclock very well, up to +50% of their nominal
clock rate, whithout requiring overvolting or anything like that, just
by changing the rate of the main PLL. Unfortunately, all clocks on the
system are derived from that PLL, and when the PLL rate is updated, so
is our pixel clock.

To counter that issue, we make sure that the panel is in VBLANK before
the rate change happens, and we will then re-set the pixel clock rate
afterwards, once the PLL has been changed, to be as close as possible to
the pixel rate requested by the encoder.

v2: Add comment about mutex usage

435be28b07 Revert "vxlan: move encapsulation warning"
This reverts commit 546c044c96.

Nothing prevents user from sending frames to "external" VxLAN devices.
In fact kernel itself may generate icmp chatter.

This is fine, such frames should be dropped.

The point of the "missing encapsulation" warning was that
frames with missing encap should not make it into vxlan_xmit_one().
And vxlan_xmit() drops them cleanly, so let it just do that.

Without this revert the warning is triggered by the udp_tunnel_nic.sh
test, but the minimal repro is:

$ ip link add vxlan0 type vxlan \
     	      	     group 239.1.1.1 \
		     dev lo \
		     dstport 1234 \
		     external
$ ip li set dev vxlan0 up

[  419.165981] vxlan0: Missing encapsulation instructions
[  419.166551] WARNING: CPU: 0 PID: 1041 at drivers/net/vxlan.c:2889 vxlan_xmit+0x15c0/0x1fc0 [vxlan]

a1bffa4874 SCSI fixes on 20200926
Three fixes: one in drivers (lpfc) and two for zoned block devices.
 The latter also impinges on the block layer but only to introduce a
 new block API for setting the zone model rather than fiddling with the
 queue directly in the zoned block driver.
