--- Changelog for v6: - rebase to 2026.3.10, version [ba7bf918dafcd093ad733b07ba490baeb20cf5da] - no more includes common.h - use <linux/time.h> MSEC_PER_SEC instead of self made - The board specific parts should be in the board MAINTAINER file - rename arch/mips/mach-lsmips/ to ...mach-loongson/ - rename functions names from lsmips_* to loongson_* - rename drivers/clk/lsmips/ to ...loongson/, rename clk driver name too - move TEXT_BASE, SPL_TEXT_BASE from mach-xxx/Kconfig to ls1c300_defconfig - rename hardware register name CONFIG_VALID to VALID (checkpatch error) - change dt bindings header license to gpl-2.0 OR MIT (checkpatch warning) - change dm-u-boot to bootph- in device tree - remove guards(#if/#endif) from include/configs/ls1c300.h - keep ARCH_LSMIPS macro, should I change it too ??? Changelog for v5: - add detail commit message - small fix in watchdog driver Changelog for v4: - rebase to [247aa5a191159ea7e03bf1918e22fbbb784cd410] - fix rebase issues - use spl without SPL_DM - fix some more codingstyle - fix some more typo - add comments about writing sdram controler - keep .noreoder and do not use delay slot Changelog for v3: - change cpu clock id from CLK_CPU to CLK_CPU_THROT - migrate all APB dev's clock id to CLK_APB - remove uarts' <reg-shift> property to use default value <0> - move /clocks/acc node to /soc/acc - call clk_request() before use a clk - make get_tbclk() return 1/2 clock of cpu - disable debug_uart by default - add ops for cpu_throt_factor clk - declare MSEC_PER_SEC for converting between sec and msec - return a error code when the wdt clock is out of range - minor format and codingstyle fixes - rebase to [9859465bfe838bc8264d45e1a1bed847bba74bad] Changelog for v2: 1. dtsi: add status disabled for uart0 ~ uart11 remove bootargs from chosen make serial0 alias for uart2 oscillator remove @0 unit-address change uart2 address to kuseg 2. cleanup Kconfig and update defconfig - make these options configurable, disabled by default: CMD_DM DM_ETH DM_GPIO DM_SPI DM_SPI_FLASH DM_RESET PINCONF PINCTRL PINMUX RESET_LSMIPS - make these options configurable, enabled by default: CLK DISPLAY_CPUINFO SYSRESET ROM_EXCEPTION_VECTORS - disabled: CONFIG_ENV_IS_IN_SPI_FLASH 3. fix codingstyle drivers/watchdog/lsmips-wdt.c - priv->base + offset - add comment for default clock value 4. remove address base definition header - remove arch/mips/mach-lsmips/ls1c300/ls1c300.h - clean up files uses this header 5. spl and debug uart - add comment for spl & debug uart pinmuxing - cleanup unused registers base header 6. dtsi - add "loongson,ls1c300-uart" to all uart node 7. board dts - add memory node to board dts, start at 0x80000000, size 64MB 8. Kconfig - make ROM_EXCEPTION_VECTORS user configureable - enable ROM_EXCEPTION_VECTORS in defconfig 9. - seperate sdram_init to sdram_init.S - add macro helpers to do sdram, pll lowlevel init 10. dtsi - move clock nodes to /clocks/xxx 11. - define CONFIG_SKIP_LOWLEVEL_INIT to 1 12. - remove option PINCTRL_LS1C300 from Kconfig 13. - dram_init, use get_ram_size() to detect ram size. 14. clk driver - create custom clock ops for PLL - remove debug code 15. - rebase to 59bffec43a657598b194b9eb30dc01eec06078c7 - remove CONFIG_SYS_MONITOR_BASE from include/configs/ Du Huanpeng (7): mips: loongson: minimal initial SoC support mips: loongson: lowlevel initialize mips: loongson: lowlevel debug serial mips: loongson: ls1c300 board support mips: loongson: add clk driver mips: loongson: add watchdog driver mips: loongson: ls1c300 dts and bindings MAINTAINERS | 9 + arch/mips/Kconfig | 11 ++ arch/mips/Makefile | 1 + arch/mips/dts/loongson32-ls1c300b.dtsi | 151 +++++++++++++++ arch/mips/dts/ls1c300-eval.dts | 30 +++ arch/mips/mach-loongson/Kconfig | 69 +++++++ arch/mips/mach-loongson/Makefile | 6 + arch/mips/mach-loongson/cpu.c | 19 ++ arch/mips/mach-loongson/include/mach/serial.h | 16 ++ arch/mips/mach-loongson/ls1c300/Makefile | 7 + arch/mips/mach-loongson/ls1c300/gpio.c | 66 +++++++ arch/mips/mach-loongson/ls1c300/init.c | 61 ++++++ .../mach-loongson/ls1c300/lowlevel_init.S | 134 +++++++++++++ arch/mips/mach-loongson/ls1c300/sdram.S | 95 ++++++++++ arch/mips/mach-loongson/ls1c300/serial.c | 104 ++++++++++ arch/mips/mach-loongson/spl.c | 46 +++++ board/loongson/ls1c300-eval/Kconfig | 12 ++ board/loongson/ls1c300-eval/MAINTAINERS | 7 + board/loongson/ls1c300-eval/Makefile | 3 + board/loongson/ls1c300-eval/board.c | 19 ++ configs/ls1c300_defconfig | 52 +++++ drivers/clk/Makefile | 1 + drivers/clk/loongson/Makefile | 3 + drivers/clk/loongson/clk-ls1c300.c | 179 ++++++++++++++++++ drivers/watchdog/Kconfig | 8 + drivers/watchdog/Makefile | 1 + drivers/watchdog/loongson_wdt.c | 127 +++++++++++++ include/configs/ls1c300.h | 36 ++++ include/dt-bindings/clock/ls1c300-clk.h | 18 ++ include/dt-bindings/reset/ls1c300-reset.h | 36 ++++ 30 files changed, 1327 insertions(+) create mode 100644 arch/mips/dts/loongson32-ls1c300b.dtsi create mode 100644 arch/mips/dts/ls1c300-eval.dts create mode 100644 arch/mips/mach-loongson/Kconfig create mode 100644 arch/mips/mach-loongson/Makefile create mode 100644 arch/mips/mach-loongson/cpu.c create mode 100644 arch/mips/mach-loongson/include/mach/serial.h create mode 100644 arch/mips/mach-loongson/ls1c300/Makefile create mode 100644 arch/mips/mach-loongson/ls1c300/gpio.c create mode 100644 arch/mips/mach-loongson/ls1c300/init.c create mode 100644 arch/mips/mach-loongson/ls1c300/lowlevel_init.S create mode 100644 arch/mips/mach-loongson/ls1c300/sdram.S create mode 100644 arch/mips/mach-loongson/ls1c300/serial.c create mode 100644 arch/mips/mach-loongson/spl.c create mode 100644 board/loongson/ls1c300-eval/Kconfig create mode 100644 board/loongson/ls1c300-eval/MAINTAINERS create mode 100644 board/loongson/ls1c300-eval/Makefile create mode 100644 board/loongson/ls1c300-eval/board.c create mode 100644 configs/ls1c300_defconfig create mode 100644 drivers/clk/loongson/Makefile create mode 100644 drivers/clk/loongson/clk-ls1c300.c create mode 100644 drivers/watchdog/loongson_wdt.c create mode 100644 include/configs/ls1c300.h create mode 100644 include/dt-bindings/clock/ls1c300-clk.h create mode 100644 include/dt-bindings/reset/ls1c300-reset.h -- 2.43.0
