From mboxrd@z Thu Jan 1 00:00:00 1970 From: Padmarao Begari Date: Fri, 15 Jan 2021 08:20:34 +0530 Subject: [PATCH v9 0/7] Microchip PolarFire SoC support Message-ID: <20210115025041.3503-1-padmarao.begari@microchip.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de 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 ab1a425524a79eeca61e7b67fdf382c7a499346f All drivers namely: NS16550 Serial, Microchip clock, Cadence eMMC and Cadence MACB Ethernet work fine on actual Microchip PolarFire SoC Icicle Kit. Changes in v9: - Remove fdt_high=0xffffffffffffffff, initrd_high=0xffffffffffffffff - Add bootm_size=0x10000000 in the environment variables Changes in v8: - Use 'priv_auto' instead of 'priv_auto_alloc_size' in the clock driver - Remove the doc warnings to build the htmldocs Changes in v7: - Allocate memory using auto-alloc feature in the clock driver - Re-order header files in the clock driver - Add comments in the clock driver Changes in v6: - Update MACB driver for 32-bit/64-bit DMA based on struct mac_config - Rename microchip,mpfs-clock.h to microchip-mpfs-clock.h - Add dual-license GPL or MIT in the clock dt-binding - Move refclk device tree node under / device tree node - Remove the dtc warnings - Fix some typos in device tree and doc 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 arch/riscv/Kconfig | 4 + arch/riscv/dts/Makefile | 1 + .../dts/microchip-mpfs-icicle-kit-u-boot.dtsi | 14 + arch/riscv/dts/microchip-mpfs-icicle-kit.dts | 421 +++++++++ arch/riscv/include/asm/types.h | 4 + board/microchip/mpfs_icicle/Kconfig | 23 + board/microchip/mpfs_icicle/mpfs_icicle.c | 99 ++- configs/microchip_mpfs_icicle_defconfig | 9 +- doc/board/index.rst | 1 + doc/board/microchip/index.rst | 9 + doc/board/microchip/mpfs_icicle.rst | 810 ++++++++++++++++++ drivers/clk/Kconfig | 1 + drivers/clk/Makefile | 1 + drivers/clk/microchip/Kconfig | 5 + drivers/clk/microchip/Makefile | 1 + drivers/clk/microchip/mpfs_clk.c | 123 +++ drivers/clk/microchip/mpfs_clk.h | 44 + drivers/clk/microchip/mpfs_clk_cfg.c | 152 ++++ drivers/clk/microchip/mpfs_clk_periph.c | 187 ++++ drivers/net/macb.c | 144 +++- drivers/net/macb.h | 6 + include/configs/microchip_mpfs_icicle.h | 59 +- .../dt-bindings/clock/microchip-mpfs-clock.h | 45 + 23 files changed, 2101 insertions(+), 62 deletions(-) create mode 100644 arch/riscv/dts/microchip-mpfs-icicle-kit-u-boot.dtsi create mode 100644 arch/riscv/dts/microchip-mpfs-icicle-kit.dts create mode 100644 doc/board/microchip/index.rst create mode 100644 doc/board/microchip/mpfs_icicle.rst create mode 100644 drivers/clk/microchip/Kconfig create mode 100644 drivers/clk/microchip/Makefile create mode 100644 drivers/clk/microchip/mpfs_clk.c create mode 100644 drivers/clk/microchip/mpfs_clk.h create mode 100644 drivers/clk/microchip/mpfs_clk_cfg.c create mode 100644 drivers/clk/microchip/mpfs_clk_periph.c create mode 100644 include/dt-bindings/clock/microchip-mpfs-clock.h -- 2.17.1
