Delta TN48M switches have a Lattice CPLD that serves multiple purposes including being a GPIO expander and providing various resets. This patch series focuses on providing support for the CPLD provided peripherals that are needed for the switch to function. The series has been refined over the last 9 months or so and currently all of the code has been reviewed and is ready for merge. We are still hovewer waiting for the DT bindings to be reviewed for a while, but hopefully Rob will provide feedback soon. --- Changes in v10: * Rebase onto 5.17-rc1 Robert Marko (6): mfd: simple-mfd-i2c: Add Delta TN48M CPLD support gpio: Add Delta TN48M CPLD GPIO driver dt-bindings: reset: Add Delta TN48M reset: Add Delta TN48M CPLD reset controller dt-bindings: mfd: Add Delta TN48M CPLD drivers bindings MAINTAINERS: Add Delta Networks TN48M CPLD drivers .../bindings/gpio/delta,tn48m-gpio.yaml | 39 ++++++ .../bindings/mfd/delta,tn48m-cpld.yaml | 90 ++++++++++++ .../bindings/reset/delta,tn48m-reset.yaml | 35 +++++ MAINTAINERS | 9 ++ drivers/gpio/Kconfig | 12 ++ drivers/gpio/Makefile | 1 + drivers/gpio/gpio-tn48m.c | 100 ++++++++++++++ drivers/mfd/Kconfig | 11 ++ drivers/mfd/simple-mfd-i2c.c | 1 + drivers/reset/Kconfig | 13 ++ drivers/reset/Makefile | 1 + drivers/reset/reset-tn48m.c | 128 ++++++++++++++++++ include/dt-bindings/reset/delta,tn48m-reset.h | 20 +++ 13 files changed, 460 insertions(+) create mode 100644 Documentation/devicetree/bindings/gpio/delta,tn48m-gpio.yaml create mode 100644 Documentation/devicetree/bindings/mfd/delta,tn48m-cpld.yaml create mode 100644 Documentation/devicetree/bindings/reset/delta,tn48m-reset.yaml create mode 100644 drivers/gpio/gpio-tn48m.c create mode 100644 drivers/reset/reset-tn48m.c create mode 100644 include/dt-bindings/reset/delta,tn48m-reset.h -- 2.34.1
