The UP board <https://up-board.org/> is the computer board for Professional Makers and Industrial Applications. We want to upstream the UP board 40-pin GP-bus Kernel driver for giving the users better experience on the software release. (not just download from UP board github) These patches are generated from the Linux kernel mainline tag v6.0. This is the PATCH V6 and fixed kernel test robot compiler warning and addressed Linus Walleij review comments. larry.lai (3): mfd: Add support for UP board CPLD/FPGA pinctrl: Add support pin control for UP board CPLD/FPGA leds: Add support for UP board CPLD onboard LEDS drivers/leds/Kconfig | 10 + drivers/leds/Makefile | 1 + drivers/leds/leds-upboard.c | 79 ++ drivers/mfd/Kconfig | 12 + drivers/mfd/Makefile | 1 + drivers/mfd/upboard-fpga.c | 492 ++++++++++ drivers/pinctrl/Kconfig | 14 + drivers/pinctrl/Makefile | 1 + drivers/pinctrl/pinctrl-upboard.c | 1390 +++++++++++++++++++++++++++++ include/linux/mfd/upboard-fpga.h | 55 ++ 10 files changed, 2055 insertions(+) create mode 100644 drivers/leds/leds-upboard.c create mode 100644 drivers/mfd/upboard-fpga.c create mode 100644 drivers/pinctrl/pinctrl-upboard.c create mode 100644 include/linux/mfd/upboard-fpga.h base-commit: 4fe89d07dcc2804c8b562f6c7896a45643d34b2f -- 2.17.1
