Subject: [PATCH 1/7] dt-bindings: pwm: renesas,rzg2l-gpt: Document RZ/G3E support
From: Biju Das <biju.das.jz@...renesas.com>
Document support for the GPT found on the Renesas RZ/G3E (R9A09G047)
SoC.
The GPT IP on these parts is similar to that on RZ/G2L but supports
only 8 interrupts per channel and has multiple clocks and resets.
Introduce a new compatible string `renesas,r9a09g047-gpt` for RZ/G3E.
