> Subject: [PATCH v5 0/7] Microchip PolarFire SoC support
>
> This patch set adds Microchip PolarFire SoC Icicle Kit support
> to RISC-V U-Boot.
>
> The patches are based upon latest U-Boot tree
> (https://gitlab.denx.de/u-boot/u-boot.git) at commit id
> 80cbd731df50b9ab646940ea862b70bcaff37225
>
> All drivers namely: NS16550 Serial, Microchip clock,
> Cadence eMMC and Cadence MACB Ethernet work fine on actual
> Microchip PolarFire SoC Icicle Kit.
>
> Changes in v5:
> - Replace compatible string "microchip,polarfire-soc" with
>   "microchip,mpfs-icicle-kit" in the device tree
> - Use "mpfs" as identifier in place of "polarfire-soc", "pfsoc"
> - Fix some typos in doc
> - Rename the clock driver files clk_pfsoc_* to mpfs_clk_*
> - Rename pfsoc-clock.h to mpfs-clock.h
>
> Changes in v4:
> - Add dual-license GPL or MIT in the device tree
> - Replace microsemi compatible strings with microchip
> - Add MACB compatible string for Microchip PolarFire SoC ethernet
> - Update MACB driver for 32-bit/64-bit DMA based on compatible string
>
> Changes in v3:
> - Add 'default y if 64BIT' for config DMA_ADDR_T_64BIT
> - Update MACB driver for 32-bit/64-bit DMA based on design config register
> - Add phy-handle in MACB driver to read the phy address from device tree
> - Fix checkpatch warnings in the clock driver
> - Remove fu540 related compatible strings from soc device tree node
> - Move refclk device tree node under /soc device tree node
> - Use local-mac-address instead of mac-address in the device tree
> - Rename device tree to microchip-mpfs-icicle-kit.dts
> - Add U-Boot specific dts microchip-mpfs-icicle-kit-u-boot.dtsi file
> - Drop the imply DMA_ADDR_T_64BIT from board config
> - Fix some typos
> - Update doc with Microchip and Custom boot-flow
>
> Changes in v2:
> - Add clock frequency for the clint device tree node
> - Move peripheral device tree nodes under /soc device tree node
> - Device tree nodes are in order based on the address
> - Enable UART0 for U-Boot logs
> - Update doc for the U-Boot logs are on UART0
> - Move clock and reset index source into patch4
> - Remove "dma_addr_r" type in the macb driver
> - Add lower_32_bits() for 32-bit address in the macb driver
> - Add set_rate() returns the new clock rate in the clock driver
>
> Padmarao Begari (7):
>   riscv: Add DMA 64-bit address support
>   net: macb: Add DMA 64-bit address support for macb
>   net: macb: Add phy address to read it from device tree
>   clk: Add Microchip PolarFire SoC clock driver
>   riscv: dts: Add device tree for Microchip Icicle Kit
>   riscv: Add Microchip MPFS Icicle Kit support
>   doc: board: Add Microchip MPFS Icicle Kit doc
