Commit a53e35db70d1 ("reset: Ensure drivers are explicit when requesting

to explicitly state whether the driver needs exclusive or shared reset
control behavior. Convert all drivers requesting exclusive resets to the
explicit API call so the temporary transition helpers can be removed.

No functional changes.

pinctrl: tegra: xusb: Silence sparse warnings

Commit 53d2a715c240 ("phy: Add Tegra XUSB pad controller support") added
a new driver for the XUSB pad controller that implements a more flexible
devicetree binding. In order to preserve backwards compatibility the old
driver can be probed if the obsolete bindings are detected.

In order to hide the legacy code, these prototypes were defined in a
header private to the new driver. This has the disadvantage of making
the sparse code checker complain about the missing declarations when
compiling the old driver and suggesting to make the functions static.

Avoid these sparse warnings by adding local prototype declarations into
the compatibility driver.

Merge tag 'pinctrl-v4.7-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl

Pull pin control updates from Linus Walleij:
"This kernel cycle was quite calm when it comes to pin control and
there is really just one major change, and that is the introduction of
devm_pinctrl_register() managed resources.

Apart from that linear development, details below.

Core changes:

- Add the devm_pinctrl_register() API and switch all applicable
drivers to use it, saving lots of lines of code all over the place.

New drivers:

- driver for the Broadcom NS2 SoC

- subdriver for the PXA25x SoCs

- subdriver for the AMLogic Meson GXBB SoC

Driver improvements:

- the Intel Baytrail driver now properly supports pin control

- Nomadik, Rockchip, Broadcom BCM2835 support the .get_direction()
callback in the GPIO portions

- continued development and stabilization of several SH-PFC SoC
subdrivers: r8a7795, r8a7790, r8a7794 etc"
