This patchset contains the initial pinctrl (IOMUX) support for the Broadcom
Cygnus SoC. The Cygnus IOMUX controller supports group based mux configuration
and allows certain pins to be muxed to GPIO function individually
Changes from v2:
- Consolidate all Broadcom pinctrl drivers into drivers/pinctrl/bcm/*
- Change the Cygnus IOMUX driver to use standard Linux pinctrl subnode
properties such as "function" and "groups" for pinmux configuration, instead
of non-standard properties such as "brcm,function" and "brcm,group"
- Use real function names like "spi0", "lcd", "key", and etc. instead of HW
specific mux names like "alt1", "alt2", "alt3", and etc.
- Add suffix "grp" to all group names
- Add support to allow individual pins to be muxed to GPIO function through
subsystem callbacks "gpio_request_enable" and "gpio_disable_free", and get rid
of all GPIO groups
- Other minor improvements in the driver
Changes from v1:
- Fix a typo in device tree binding document
Ray Jui (4):
pinctrl: bcm: consolidate Broadcom pinctrl drivers
pinctrl: Broadcom Cygnus pinctrl device tree binding
pinctrl: cygnus: add initial IOMUX driver support
ARM: dts: enable IOMUX for Broadcom Cygnus

+Broadcom Cygnus IOMUX Controller
+
+The Cygnus IOMUX controller supports group based mux configuration. In
+addition, certain pins can be muxed to GPIO function individually.
+
+Required properties:
+
+- compatible:
+ Must be "brcm,cygnus-pinmux"
+
+- reg:
+ Define the base and range of the I/O address space that contains the Cygnus
+IOMUX registers
+
+Required properties in child nodes:
+
+- function:
+ The mux function to select
+
+- groups:
+ The list of groups to select with a given function
+
+Each child node represents a configuration. Client devices reference the child
+node to enable a mux configuration
+
+For more details, refer to
+Documentation/devicetree/bindings/pinctrl/pinctrl-bindings.txt
+
+For example:
+
+ pinmux: pinmux@0x0301d0c8 {
+ compatible = "brcm,cygnus-pinmux";
+ reg = <0x0301d0c8 0x1b0>;
+

+
+ i2s_1: i2s_1 {
+ function = "i2s1";
+ groups = "i2s1_0_grp", "i2s1_1_grp";
+ };
+
+ i2s_2: i2s_2 {

Not: the last 2 consts are quite weird - if you want to make an instance
of cygnus_pin_group immutable you declare it as a const (and I see you
are already doing that below). With the structure as it laid out
currently you can only do static initializers.

You also need to either provide remove() method or disallow unbinding
via sysfs by setting suppress_bind_attrs in platform driver.

I do not expect this driver to ever be compiled as module and

The pinctrl code says:
"@drv_data: driver-defined per-pin data. pinctrl core does not touch
this"
so we could theoretically cast away the constness and restore it when
we access drv_data in pin control methods, but I won't insist. I am
not sure which way looks nicer.
Thanks.

Yeah, I agreed that by declaring the cygnus_pins array const, it makes
it more obvious that "we do not expect any of its parameters to change."
But later if we cast &gpio_mux to void * before assigned to drv_data of
pinctrl_pin_desc, we sort of break it up...I'll keep this part of code
as it is for now.
Thanks,
Ray
