Note that the Linux kernel also\nhas a driver for that [1], but not yet enabled [2]. However it has been\nsuggested that it's better to implement reboot support at the OpenSBI\nlevel [3].\n\nThe first patch add I2C support for the SpacemiT P1 SoC, and the second\none reboot support for the SpacemiT P1 PMIC. This chip is also used on\nsome SpacemiT K3 platforms, that's why I decided to add it at the PMIC\nlevel (lib/utils/reset/fdt_reset_spacemit_p1.c) instead of at the\nplatform level (platform/generic/spacemit/k1.c).\n\nThis patchset has been tested on a Banana Pi BPI-F3 board and on a\nMilk-V Jupiter board.\n\n[1] https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/power/reset/spacemit-p1-reboot.c\n[2] https://lore.kernel.org/all/20260401165437.1048786-3-aurelien@aurel32.net/\n[3] https://lore.kernel.org/all/c1f466f8-4e76-43a2-a7a2-126415fd1f56@sifive.com/\n\nAurelien Jarno (2):\n lib: utils/i2c: add minimal SpacemiT I2C driver\n lib: utils/reset: add SpacemiT P1 PMIC support\n\n lib/utils/i2c/Kconfig | 4 +\n lib/utils/i2c/fdt_i2c_spacemit.c | 220 ++++++++++++++++++++++++\n lib/utils/i2c/objects.mk | 3 +\n lib/utils/reset/Kconfig | 4 +\n lib/utils/reset/fdt_reset_spacemit_p1.c | 112 ++++++++++++\n lib/utils/reset/objects.mk | 3 +\n platform/generic/configs/defconfig | 2 +\n 7 files changed, 348 insertions(+)\n create mode 100644 lib/utils/i2c/fdt_i2c_spacemit.c\n create mode 100644 lib/utils/reset/fdt_reset_spacemit_p1.c" }
