Subject: [PATCH v7 10/11] riscv: dts: microchip: add new peripherals to icicle kit device tree
Date: Mon, 14 Feb 2022 13:58:40 +0000	[thread overview]
Message-ID: <20220214135840.168236-11-conor.dooley@microchip.com> (raw)
In-Reply-To: <20220214135840.168236-1-conor.dooley@microchip.com>

From: Conor Dooley <conor.dooley@microchip.com>

Add new peripherals to the MPFS, and enable them in the Icicle kit
device tree:

2x SPI, QSPI, 3x GPIO, 2x I2C, Real Time Counter, PCIE controller,
USB host & system controller.
