This series update SiFive Unleashed clock driver and Cadence MACB driver so that: 1. It is in sync with upstream Linux driver 2. It uses latest DT bindings as-per upstream Linux driver
With this series, we can now use latest DT bindings with U-Boot. I have tested SiFive Serial driver and Cadence MACB ethernet driver with this changes and both work fine.
The legacy FSBL will still pass DTB with older DT bindings which will break the updated SiFive Unleashed clock driver. To tackle this, we have embedded DTB in OpenSBI FW_PAYLOAD firmware for SiFive Unleashed so that OpenSBI will override and pass updated DTB to U-Boot.
The updated DTB passed by OpenSBI is in fact the DTB build by upstream Linux so we can straight away pass this DTB to Linux as well.
This series can be found in riscv_unleashed_clk_sync_v12 branch at: https://github.com/avpatel/u-boot.git
To try this series use latest OpenSBI at: https://github.com/riscv/opensbi.git And Linux-5.3-rc1 from v5.3-rc1_unleashed branch at: https://github.com/avpatel/linux.git
Changes since v11: - Dropped PATCH1, PATCH2 and PATCH3 because these are already merged by Joe - Rebased PATCH4 upon Joe's u-boot-net gitrepo
Changes since v10: - Addressed comments from Joe on MACB driver changes
Changes since v9: - Remove all accepted and merged patches except MACB driver patches - Rebased MACB driver patches upon v2 patches from Ramon Fried (Refer, https://www.mail-archive.com/u-boot@lists.denx.de/msg334300.html) - Added separate patch to sync-up SiFive Unleashed config header with QEMU RISC-V virt machine config header - Added separate patch for more updates to SiFive Unleashed README
Changes since v8: - Removed probe() from macb_config for PATCH6 - Renamed set_tx_clk() to clk_init() in macb_config for PATCH6
Changes since v7: - Update PATCH6 to not treat dma_burst_length = 0 as skip gmac_configure_dma() - Update PATCH9 to check endianess at runtime
Changes since v6: - Added separate patch to fix endianess check in gmac_configure_dma()
Changes since v5: - Addressed Ramon's comments in PATCH6 - Addressed Bin's comments in PATCH7
Changes since v4: - Rebased patches upon Ramon's MACB changes (Refer, https://patchwork.ozlabs.org/patch/1114025/) - Added PATCH7 to setup ethaddr based on board serial number read from OTP - Added PATCH8 to update documentation
Changes since v3: - Extend MACB ethernet driver for SiFive Unleashed board (just like Linux)
Changes since v2: - Dropped PATCH6 which adds new compatible string to MACB driver because more changes are required in MACB driver for different ethernet speeds
Changes since v1: - Dropped GEMGXL clock driver - Added new compatible string for SiFive MACB ethernet
