From: Raymond Mao <[email protected]> This series adds pinctrl, GPIO, and SPI NOR flash support for the SpacemiT K1. Drivers are usable in both SPL and U-Boot proper. In SPL, the QSPI controller and SPI NOR flash are probed during early init, and the SPL boot device is changed from memory-mapped NOR to SPI so the common loader reads the next-stage image from NOR. It sits on top of the K1 SPL bring-up series [1], which depends on the K1 clock/reset/dts migration series [2].
To apply on origin/master, two prerequisite series on lore must be applied first, in this order: 1. K1 clock/reset/dts migration [2] (8 patches) 2. K1 SPL bring-up v4 [1] (14 patches) 3. This series (9 patches) [1] https://lore.kernel.org/u-boot/[email protected]/ [2] https://lore.kernel.org/u-boot/20260510-b4-k1-clk-reset-upstream-dts-v1-0-db0b0503e...@riscstar.com/ Guodong Xu (3): spl: k1: enable SPI NOR flash detection and boot spacemit: k1: Add multiple device tree support configs: k1: enable pinctrl and gpio Raymond Mao (6): mtd: spi: select SPL_SPI_FLASH_TINY in SPL stage mtd: spi: enable spi_nor_remove() in soft reset config spi: fsl: add support for Spacemit K1 SoC riscv: binman: Always set default configuration in FIT image pinctrl: add pinctrl driver for Spacemit K1 SoC gpio: add gpio driver for Spacemit K1 SoC arch/riscv/dts/binman.dtsi | 2 - arch/riscv/dts/k1-musepi-pro-u-boot.dtsi | 273 ++++++++++++ board/spacemit/k1/MAINTAINERS | 3 + board/spacemit/k1/spl.c | 78 +++- configs/spacemit_k1_defconfig | 36 +- drivers/gpio/Kconfig | 8 + drivers/gpio/Makefile | 1 + drivers/gpio/spacemit_gpio.c | 253 +++++++++++ drivers/mtd/spi/Makefile | 5 +- drivers/mtd/spi/sf_probe.c | 8 +- drivers/pinctrl/Kconfig | 1 + drivers/pinctrl/Makefile | 1 + drivers/pinctrl/spacemit/Kconfig | 9 + drivers/pinctrl/spacemit/Makefile | 2 + drivers/pinctrl/spacemit/pinctrl-k1.c | 546 +++++++++++++++++++++++ drivers/spi/fsl_qspi.c | 9 + 16 files changed, 1217 insertions(+), 18 deletions(-) create mode 100644 arch/riscv/dts/k1-musepi-pro-u-boot.dtsi create mode 100644 drivers/gpio/spacemit_gpio.c create mode 100644 drivers/pinctrl/spacemit/Kconfig create mode 100644 drivers/pinctrl/spacemit/Makefile create mode 100644 drivers/pinctrl/spacemit/pinctrl-k1.c -- 2.25.1
