RDA8810PL is an ARM Cortex A5 based SoC with Vivante's GC860 GPU. The SoC has been added as a new ARM sub architecture with myself and Andreas as the maintainers. More information about the boards can be found in below links: 1. Orange Pi 2G-IoT - http://www.orangepi.org/OrangePi2GIOT/ 2. Orange Pi i96 - https://www.96boards.org/product/orangepi-i96/ This patchset is based on the initial revision sent out by Andreas long back (http://lists.infradead.org/pipermail/linux-arm-kernel/2017-June/515951.html). I have extended his patchset with proper irqchip and UART drivers. Now, boards can boot into initramfs with console at UART2. Thanks, Mani Changes in v2: * Used readl/writel_relaxed calls for both irqchip and timer drivers as per Marc's review. * Implemented the logic to prevent counter wrapping during read as suggested by Marc. * Used the timer-of API as per Daniel's suggestion. * Added description about the timer in both commit log and driver. * Changed the Vendor name for RDA to Unisoc Communications Inc. * Removed the soc node level and cleaned up devicetrees as per Rob's review. * Merged interrupt controller DT patch to SoC. * Moved aliases to board dts as per Arnd's suggestion. * Removed RDA Micro support mail address and used Unisoc one and added my missing signed off by tag as per Andreas's comments.
