Krzysztof Kozlowski 84e85359f4 dt-bindings: drop redundant part of title (end, part three)
The Devicetree bindings document does not have to say in the title that
it is a "binding", but instead just describe the hardware.

Drop trailing "bindings" in various forms (also with trailing full
stop):

  find Documentation/devicetree/bindings/ -type f -name '*.yaml' \
    -not -name 'trivial-devices.yaml' \
    -exec sed -i -e 's/^title: \(.*\) [bB]indings\?\.\?$/title: \1/' {} \;

title: Simple MMC power sequence provider
maintainers:
- Ulf Hansson <ulf.hansson@linaro.org>
description:
The purpose of the simple MMC power sequence provider is to supports a set
of common properties between various SOC designs. It thus enables us to use
the same provider for several SOC designs.
properties:
compatible:
const: mmc-pwrseq-simple
reset-gpios:
minItems: 1
# Put some limit to avoid false warnings
maxItems: 32
description:
contains a list of GPIO specifiers. The reset GPIOs are asserted
at initialization and prior we start the power up procedure of the card.
They will be de-asserted right after the power has been provided to the
card.
clocks:
minItems: 1
description: Handle for the entry in clock-names.
clock-names:
items:
- const: ext_clock
description: External clock provided to the card.
post-power-on-delay-ms:
description:
Delay in ms after powering the card and de-asserting the
reset-gpios (if any).
power-off-delay-us:
description:
Delay in us after asserting the reset-gpios (if any)
during power off of the card.
