[PATCH 2/7] ARM: dts: lpc32xx: Set motor PWM #pwm-cells property value to 3 cells

[Vladimir Zapolskiy]

Since commit 4cd2f417a0ac ("dt-bindings: pwm: Convert lpc32xx-pwm.txt
to yaml format") both types of PWM controlles on NXP LPC32xx SoC
fairly gained 3 cells, reflect it in the platform dtsi file.

The change removes a dt binding checker warning:

    mpwm@400e8000: #pwm-cells:0:0: 3 was expected

[PATCH 3/7] ARM: dts: lpc32xx: Correct motor PWM device tree node name

[Vladimir Zapolskiy]

Change once a customly selected 'mpwm' node name in favour of
the expected 'pwm' one.

The change eliminates a reported warning:

    mpwm@400e8000: $nodename:0: 'mpwm@400e8000' does not match '^pwm(@.*|-([0-9]|[1-9][0-9]+))?$'

[PATCH 6/7] ARM: dts: lpc32xx: Specify #dma-cells property of PL080 DMA controller

[Vladimir Zapolskiy]
