MIPS: DTS: img: add device tree for Marduk board
Add support for Imagination Technologies' Marduk board which is based on Pistachio SoC. It is also known as Creator Ci40. Marduk is legacy name and will be there for decades. Documentation for this board can be found on https://docs.creatordev.io/ci40/ This patch adds initial support for board with following peripherals: * PWM based heartbeat LED * GPIO based buttons * SPI NOR flash on SPI1 * UART0 and UART1 * SD card * Ethernet * USB * PWM * ADC * I2C Signed-off-by: Rahul Bedarkar <rahul.bedarkar@imgtec.com> Acked-by: Rob Herring <robh@kernel.org> Acked-by: James Hartley <james.hartley@imgtec.com> Cc: Mark Rutland <mark.rutland@arm.com> Cc: linux-mips@linux-mips.org Cc: devicetree@vger.kernel.org Cc: linux-kernel@vger.kernel.org Patchwork: https://patchwork.linux-mips.org/patch/14394/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>hifive-unleashed-5.1
