[PATCH 02/11] dt-bindings: pwm: renesas,pwm-rcar: Add support for R-Car X5H

[Geert Uytterhoeven]

Document support for the Pulse Width Modulation (PWM) module in the
Renesas R-Car X5H (R8A78000) SoC.

R-Car Gen5 enlarged the PWM output cycle and high-level period fields
from 10 to 24 bits.  While the added register bits have initial states
of all-zeroes, and thus look compatible with previous generations, the
register bits may have been modified before Linux boots.  Hence no
fallback to renesas,pwm-rcar is included.
