193b40aeb5 kconfig: sort found symbols by relevance
When searching for symbols, return the symbols sorted by relevance.

Sorting is done as thus:
  - first, symbols that match exactly
  - then, alphabetical sort

Since the search can be a regexp, it is possible that more than one symbol
matches exactly. In this case, we can't decide which to sort first, so we
fallback to alphabeticall sort.

Explain this (new!) sorting heuristic in the documentation.

Changes v1->v2:
  - drop the previous, complex heuristic in favour of a simpler heuristic

b58f0273f0 pinctrl-tz1090-pdc: add TZ1090 PDC pinctrl driver
Add a pin control driver for the TZ1090's low power pins via the
powerdown controller SOC_GPIO_CONTROL registers.

These pins have individually controlled pull-up, and group controlled
schmitt, slew-rate, drive-strength, and power-on-start (pos).

The pdc_gpio0 and pdc_gpio1 pins can also be muxed onto the
ir_mod_stable_out and ir_mod_power_out functions respectively. If no
function is set they remain in GPIO mode. These muxes can be overridden
by requesting them as GPIOs.

42dc30231b regulator: max8973: initial DT support
This patch adds primitive DT support to the max8973 regulator driver. None
of the configuration parameters, supported in the platform data are yet
available in DT, therefore no configuration is performed if booting with
no platform data. This means, that DT instantiation can only be used on
boards, where no run-time configuration of the chip is required. In such
cases the driver can be used to scale its output voltage. In the future
support for configuration parameters should be added.

0c4df02d73 x86: Add NMI duration tracepoints
This patch has been invaluable in my adventures finding
issues in the perf NMI handler.  I'm as big a fan of
printk() as anybody is, but using printk() in NMIs is
deadly when they're happening frequently.

Even hacking in trace_printk() ended up eating enough
CPU to throw off some of the measurements I was making.

14c63f17b1 perf: Drop sample rate when sampling is too slow
This patch keeps track of how long perf's NMI handler is taking,
and also calculates how many samples perf can take a second.  If
the sample length times the expected max number of samples
exceeds a configurable threshold, it drops the sample rate.

This way, we don't have a runaway sampling process eating up the
CPU.

This patch can tend to drop the sample rate down to level where
perf doesn't work very well.  *BUT* the alternative is that my
system hangs because it spends all of its time handling NMIs.

I'll take a busted performance tool over an entire system that's
busted and undebuggable any day.

BTW, my suspicion is that there's still an underlying bug here.
Using the HPET instead of the TSC is definitely a contributing
factor, but I suspect there are some other things going on.
But, I can't go dig down on a bug like that with my machine
hanging all the time.

The driver and documentation are updated.

2dac912809 leds: lp55xx: support dynamic channel settings in the device tree structure
Currently, the LP55xx DT structure supports max 3 channels.
However, LP5523 has max 9 channels and LP5562 has 4 channels.
To enhance this constraint, the DT structure has been changed.

 (a) Use the child node for various channel settings instead of fixed array
 (b) Remove 'num_channel' property.
     This value can be retrieved by counting the children node.
 (c) 'chan-name' property supported
 (d) Documentation updates for LP5521 and LP5523

646572c77d clk: add support for Rockchip gate clocks
This adds basic support for gate-clocks on Rockchip SoCs.
There are 16 gates in each register and use the HIWORD_MASK
mechanism for changing gate settings.

The gate registers form a continuos block which makes the dt node
structure a matter of taste, as either all 160 gates can be put into
one gate clock spanning all registers or they can be divided into
the 10 individual gates containing 16 clocks each.
The code supports both approaches.
