Subject: [PATCH v4 0/2] pinctrl: nuvoton: add driver for NPCM7xx

This patch set adds pinmux and GPIO controller for the Nuvoton
NPCM750/730/715/705 Baseboard Management Controller (BMC).

The Nuvoton BMC NPCM750/730/715/705 Pinmux functions accessible
only for pin groups and pinconf parameters available only for
individual pins.

The Nuvoton BMC NPCM750/730/715/705 has eight identical GPIO
modules, each module has 32 GPIO ports.

Most of the GPIO ports are multiplexed with other system functions.

The NPCM7xx pinctrl and GPIO driver tested on NPCM750 evaluation board.

this patch set depend on
gpio: mmio: add inverted direction get_set io support approval.
https://lore.kernel.org/patchwork/patch/968891/
without adding BGPIOF_INVERTED_REG_DIR to include/linux/gpio/driver.h
the build will failed.

Addressed comments from:.
- kbuild test robot: https://www.spinics.net/lists/kernel/msg2868491.html

conversion about it with Linus Walleij:
- https://www.spinics.net/lists/devicetree/msg241973.html

Changes since version 3:
- Remove Kconfig MFD_SYSCON dependency.
- Add BGPIOF_INVERTED_REG_DIR flag.
- dt-binding documentation haven't changed.

Changes since version 2:
- Using GPIO_GENERIC (mmio).
- Add Kconfig MFD_SYSCON dependency.
- Remove unnecessary code from the direction output function.
- dt-binding documentation haven't changed.

Changes since version 1:
- Remove Kconfig MFD_SYSCON dependency.
- Modify setfunc function.
- Modify dt-binding documentation according Rob comments.

+Nuvoton NPCM7XX Pin Controllers
+
+The Nuvoton BMC NPCM7XX Pin Controller multi-function routed through
+the multiplexing block, Each pin supports GPIO functionality (GPIOx)
+and multiple functions that directly connect the pin to different
+hardware blocks.
+
+Required properties:
+- #address-cells : should be 1.
+- #size-cells : should be 1.
+- compatible : "nuvoton,npcm750-pinctrl" for Poleg NPCM7XX.
+- ranges : defines mapping ranges between pin controller node (parent)
+ to GPIO bank node (children).
+
+=== GPIO Bank Subnode ===
+
+The NPCM7XX has 8 GPIO Banks each GPIO bank supports 32 GPIO.
+
+Required GPIO Bank subnode-properties:
+- reg : specifies physical base address and size of the GPIO
+ bank registers.
+- gpio-controller : Marks the device node as a GPIO controller.
+- #gpio-cells : Must be <2>. The first cell is the gpio pin number
+ and the second cell is used for optional parameters.
+- interrupts : contain the GPIO bank interrupt with flags for falling edge.
+- gpio-ranges : defines the range of pins managed by the GPIO bank controller.
+
+For example, GPIO bank subnodes like the following:
+ gpio0: gpio@f0010000 {
+ gpio-controller;
+ #gpio-cells = <2>;
+ reg = <0x0 0x80>;
+ interrupts = <GIC_SPI 116 IRQ_TYPE_LEVEL_HIGH>;
+ gpio-ranges = <&pinctrl 0 0 32>;
+ };
+
+=== Pin Mux Subnode ===
+
+- pin: A string containing the name of the pin
+ An array of strings, each string containing the name of a pin.
+ These pin are used for selecting pin configuration.
+
+The following are the list of pins available:
+ "GPIO0/IOX1DI", "GPIO1/IOX1LD", "GPIO2/IOX1CK", "GPIO3/IOX1D0",

Hi Tomer,

this is starting to look really good!

Please try this with my patch and drop the new DIR_INV flag that I think
we do not need anymore after that.

Other small bits:

Very nice! You sorted it out perfectly.

I see some GPIO drivers do this but I don't think you need to use these indirect
->read_reg() and ->write_reg() accessors, it just obscures things. If
you need to
access these registers I think it's fine to just use the base and
read/write them.
But it's your pick, I will not insist. Maybe it's a matter of taste.

Exactly as I think it should work, sweet!

Worries me a bit. This seems to be like this because you register the
GPIO before the pin controller.

Normally we would register in the other order, and the code inside
of_gpiochio_add() as part of [devm_]gpiochip_add() will parse the phandle
and add the ranges when you add the GPIO chip.

Is this impossible to solve this cleanly?
