Hello, This patchset adds initial RDA8810PL SoC and Orange Pi boards (2G IoT and i96) support. 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 v3: As per Marc's review: * Removed unused header and defines from irqchip driver. * Removed setting flow handlers from set_type callback. * Minor code cleanups. As per Arnd's review: * Modified the UART indexes to start from 1 to match the SoC numbering * Enabled exposed UARTs (all 3 on both boards) * Modified the serial aliases as per board numbering * Added Greg's Reviewed-by tag for serial driver. 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.
