70a2b4220e pinctrl: mediatek: do not probe gpio driver if not enabled
The mtk pinctrl driver is a combination driver with support for both
pinctrl and gpio. When this driver is used in SPL, gpio support may not be
enabled, and this will result in a compilation error.

To fix this, macros are added to make sure gpio related code will only be
compiled when gpio support is enabled.

Renesas RZ/G2E (a.k.a. r8a774c0) is pin compatible with R-Car

7e0a96d559 dm: gpio: Add a way to update flags
It is convenient to be able to adjust some of the flags for a GPIO while
leaving others alone. Add a function for this.

Update dm_gpio_set_dir_flags() to make use of this.

Also update dm_gpio_set_value() to use this also, since this allows the
open-drain / open-source features to be implemented directly in the
driver, rather than using the uclass workaround.

Update the sandbox tests accordingly. This involves a lot of changes to
dm_test_gpio_opendrain_opensource() since we no-longer have the direciion
being reported differently depending on the open drain/open source flags.

Also update the STM32 drivers to let the uclass handle the active low/high
logic.

Drop the GPIOD_FLAGS_OUTPUT() macro which is no-longer used.

9648789e26 dm: gpio: Rename get_dir_flags() method to get_flags()
It is more useful to be able to read all the flags, not just the direction
ones. In fact this is what the STM32 driver does. Update the method name
to reflect this.

Tweak the docs a little and use 'flagsp' as the return argument, as is

54f5bf3d61 pinctrl: stmfx: Fix pin configuration issue
pin-controller pin's name must be equal to pin's name used in device
tree with "pins" DT property.

Issue detected on stm32mp157c-ev1 board with goodix touchscreen.
In DT, the goodix's pin is declared in DT with the node:

        goodix_pins: goodix {
		pins = "gpio14";
		bias-pull-down;
	};

Whereas in stmfx pin-controller driver, pin's name are equal to
"stmfx_gpioxx" where xx is the pin number.
This lead to not configure stmfx's pins at probe because pins is
identified by its name (see pinctrl_pin_name_to_selector() in
pinctrl-generic.c) and stmfx pin "gpio14" can't be found.

To fix this issue, come back to the original stmfx pin's name.

Revert "pinctrl: stmfx: update pin name"

This reverts commit 38d30cdcd65c73eeefac5efa328ad444a53b77dd.

cc6aa80dd1 pinctrl: renesas: Make sure the pin type is updated after setting the MUX
By default on startup all the pin types are configured to
PINMUX_TYPE_NONE (in sh_pfc_map_pins()), when pin is set as GPIO the
pin type is updated to PINMUX_TYPE_GPIO. But the type is not updated
when the pin is set as a function in sh_pfc_pinctrl_pin_set() or
sh_pfc_pinctrl_group_set() calls (these calls only set the MUX if
the pin type is PINMUX_TYPE_NONE ie unused).

So with the current implementation pin functionality could be overwritten
silently, for example if the same pin is added for SPI and serial.

This patch makes sure of updating pin type after every successful call to
sh_pfc_config_mux() and thus fixing from pin functionality to be
overwritten. Also a warning message is printed if the current pin is being
overwritten before abort.

This also avoids pin re-muxing to same type that is for example from
command line device is asked to re-probe/select (mmc dev x) we return
early with success in this case as the pin is already muxed.

caa4daa2ae dm: treewide: Rename 'platdata' variables to just 'plat'
We use 'priv' for private data but often use 'platdata' for platform data.
We can't really use 'pdata' since that is ambiguous (it could mean private
or platform data).

Rename some of the latter variables to end with 'plat' for consistency.

41575d8e4c dm: treewide: Rename auto_alloc_size members to be shorter
This construct is quite long-winded. In earlier days it made some sense
since auto-allocation was a strange concept. But with driver model now
used pretty universally, we can shorten this to 'auto'. This reduces
verbosity and makes it easier to read.

Coincidentally it also ensures that every declaration is on one line,
thus making dtoc's job easier.

20da4e0231 dm: Drop uses of dev_set_of_offset()
The need for this can be avoided by passing the correct node to the
device_bind() function.

This function is not needed since the standard device_bind() can be used
instead.

e12052b322 dm: core: Rename device_bind() to device_bind_offset()
This function is not necessary anymore, since device_bind_ofnode() does
the same thing and works with both flattree and livetree.

Rename it to indicate that it is special.

c2a8181d45 pinctrl: stmfx: update pincontrol and gpio device name
The device name is used in pinmux command and in log trace
so it is better to use the parent parent name ("stmfx@42" for
example) than a generic name ("pinctrl" or "stmfx-gpio")
to identify the device instance.
