This series seem to handle the RV1103B variant and not the RV1106/RV1103 variant, please name parts as rv1103b to match vendor U-Boot or is the rv1106/rv1103 and rv1103b fully compatible? > Upstreaming the RV1103 devicetree in Linux is ongoing, but to avoid blocking > U-Boot support, this series introduces board-specific devicetrees for now. > Once the Linux RV1103 devicetrees are upstreamed, the OF_UPSTREAM mechanism > can be enabled. For the Rockchip platform we typically expect e.g. dt-bindings headers for core parts to be upstreamed to Linux and picked from dts/upstream for new SoC support. Please at least send out clk and pinctrl dt-bindings and drivers for Linux before a v2 of this series :-) Regards, Jonas > Fabio Estevam (7): > pinctrl: rockchip: Add support for RV1103 > clk: rockchip: Add support for RV1103 > tools: rkcommon: Add rv1103 support > rockchip: spl-boot-order: Add SPI NAND support > spl: Add SPI NAND support via MTD in SPL > ARM: dts: Add RV1103 Omega4 support > omega4-rv1103: Add initial support > > arch/arm/dts/rv1103-omega4-u-boot.dtsi | 11 + > arch/arm/dts/rv1103-omega4.dts | 40 + > arch/arm/dts/rv1103-u-boot.dtsi | 4 + > arch/arm/dts/rv1103.dtsi | 267 +++++ > .../include/asm/arch-rockchip/cru_rv1103.h | 271 +++++ > .../include/asm/arch-rockchip/grf_rv1103.h | 31 + > arch/arm/include/asm/arch-rv1103/boot0.h | 11 + > arch/arm/mach-rockchip/Kconfig | 14 + > arch/arm/mach-rockchip/Makefile | 1 + > arch/arm/mach-rockchip/rv1103/Kconfig | 23 + > arch/arm/mach-rockchip/rv1103/Makefile | 12 + > arch/arm/mach-rockchip/rv1103/boot0.h | 5 + > arch/arm/mach-rockchip/rv1103/clk_rv1103.c | 32 + > arch/arm/mach-rockchip/rv1103/rv1103.c | 133 ++ > arch/arm/mach-rockchip/rv1103/syscon_rv1103.c | 19 + > arch/arm/mach-rockchip/spl-boot-order.c | 11 +- > board/onion/omega4_rv1103/Kconfig | 12 + > board/onion/omega4_rv1103/MAINTAINERS | 6 + > board/onion/omega4_rv1103/Makefile | 7 + > board/onion/omega4_rv1103/omega4_rv1103.c | 19 + > board/onion/omega4_rv1103/omega4_rv1103.env | 5 + > common/spl/Kconfig | 10 +- > common/spl/Makefile | 1 + > common/spl/spl_spi_nand.c | 82 ++ > configs/omega4-rv1103_defconfig | 82 ++ > doc/board/index.rst | 1 + > doc/board/onion/index.rst | 9 + > doc/board/onion/omega4-rv1103.rst | 56 + > drivers/clk/rockchip/Makefile | 1 + > drivers/clk/rockchip/clk_rv1103.c | 1068 +++++++++++++++++ > drivers/mtd/Makefile | 1 + > drivers/mtd/nand/Makefile | 13 +- > drivers/pinctrl/Kconfig | 10 + > drivers/pinctrl/rockchip/Makefile | 1 + > drivers/pinctrl/rockchip/pinctrl-rv1103.c | 411 +++++++ > include/configs/omega4_rv1103.h | 11 + > include/configs/rv1103_common.h | 14 + > include/dt-bindings/clock/rv1103-cru.h | 489 ++++++++ > tools/rkcommon.c | 1 + > 39 files changed, 3191 insertions(+), 4 deletions(-) > create mode 100644 arch/arm/dts/rv1103-omega4-u-boot.dtsi > create mode 100644 arch/arm/dts/rv1103-omega4.dts > create mode 100644 arch/arm/dts/rv1103-u-boot.dtsi > create mode 100644 arch/arm/dts/rv1103.dtsi > create mode 100644 arch/arm/include/asm/arch-rockchip/cru_rv1103.h > create mode 100644 arch/arm/include/asm/arch-rockchip/grf_rv1103.h > create mode 100644 arch/arm/include/asm/arch-rv1103/boot0.h > create mode 100644 arch/arm/mach-rockchip/rv1103/Kconfig > create mode 100644 arch/arm/mach-rockchip/rv1103/Makefile > create mode 100644 arch/arm/mach-rockchip/rv1103/boot0.h > create mode 100644 arch/arm/mach-rockchip/rv1103/clk_rv1103.c > create mode 100644 arch/arm/mach-rockchip/rv1103/rv1103.c > create mode 100644 arch/arm/mach-rockchip/rv1103/syscon_rv1103.c > create mode 100644 board/onion/omega4_rv1103/Kconfig > create mode 100644 board/onion/omega4_rv1103/MAINTAINERS > create mode 100644 board/onion/omega4_rv1103/Makefile > create mode 100644 board/onion/omega4_rv1103/omega4_rv1103.c > create mode 100644 board/onion/omega4_rv1103/omega4_rv1103.env > create mode 100644 common/spl/spl_spi_nand.c > create mode 100644 configs/omega4-rv1103_defconfig > create mode 100644 doc/board/onion/index.rst > create mode 100644 doc/board/onion/omega4-rv1103.rst > create mode 100644 drivers/clk/rockchip/clk_rv1103.c > create mode 100644 drivers/pinctrl/rockchip/pinctrl-rv1103.c > create mode 100644 include/configs/omega4_rv1103.h > create mode 100644 include/configs/rv1103_common.h > create mode 100644 include/dt-bindings/clock/rv1103-cru.h
