The blackfin pinmux and gpio controller doesn't allow user to set up 1 pin
for both GPIO and peripheral function. So, add flag strict in struct
pinctrl_desc to check both gpio_owner and mux_owner before approving the
pin request.
v2-changes:
- if strict
Patch 4de60970abf9f49737f51ec6e7a1e3bcf6d36742 introduced this code.
Either the type is wrong, or the test should not be performed.
Considering the return type of acpi_gpiochip_pin_to_gpio_offset and
the fact it can return -EINVAL, I would say it is the former.
Qipeng, can you post a fix if you
This rearranges the GPIO drivers Kconfig symbols alphabetically
as the top comment in the file already states they should be.
No functional changes whatsoever.

Get rid of AC97, MODULbus and other weird subheadings for
GPIO drivers. Move all MFD drivers out of I2C etc and in under
the MFD comment. This is too weird as it is and makes no
sense, if the dependent parent driver is MFD, group these as
MFD GPIO drivers. Alphabetize and move this comment group
Create Kconfig submenus for memory mapped, I2C, MFD,
PCI, SPI and USB GPIO drivers to help navigate the forest
of drivers in this subsystem. The I2C, SPI and USB menus
get dependencies so we don't have to see them unless we
have the required subsystem enabled in the first place.
