[1/1] ARM: dts: Add RDA8810PL GPIO controllers

Commit Message

Manivannan Sadhasivam Oct. 30, 2019, 10:11 a.m. UTC

Add GPIO controllers for RDA8810PL SoC. There are 4 GPIO controllers
in this SoC with maximum of 32 gpios. Except GPIOC, all controllers
are capable of generating edge/level interrupts from first 8 lines.
