commit 92c959bae2e54ba1e2540ba5f813f7752bd76be1 upstream.
If pm_runtime_resume_and_get() fails then it returns w/o the RPM usage
counter being incremented. In this case call pm_runtime_put() in
remove() will result in a usage counter imbalance. Therefore check the
return code of pm_runtime_resume_and_get() and bail out in case of error.Fixes: bee08559701f ("reset: renesas: Add RZ/G2L usbphy control driver")

Commit c045ceb5a145 ("reset: tegra-bpmp: Handle errors in BPMP

exposed an issue in the Tegra194 HDA driver and now resetting the
Tegra194 HDA controller is failing. For now revert the commit
c045ceb5a145 ("reset: tegra-bpmp: Handle errors in BPMP response")

This is an reset driver to implement a reset controller
device DISPMIX on IMX8MM and IMX8MN platforms. Dispmix
reset is used to reset or enable related buses and clks
for the submodules in DISPMIX.All the dispmix resets are divided into three subgroups:
sft_rstn, clk_en and mipi_rst, and each of them contains
several reset lines to control several different modules
on and off in DISPMIX which doesn't require the standard
reset flow, but only line assert and deassert operations.Signed-off-by: Fancy Fang

The reset PIN may loss its state when system suspend due to GPIO
controller power off. Set pinctrl as "sleep" state to keep PIN
voltage during system suspend, and configurate pinctrl as "default"
state after system resume back. Because GPIO resume back earlier
than gpio-reset, then GPIO signal can control the PIN voltage again.Reviewed-by: Richard Zhu

It's a little bit late to register gpio-reset driver at module_init
time, because gpio-reset provides reset control via gpio for other
devices which are mostly probed at module_init time too. And it
becomes even worse, when the gpio comes from IO expander on I2C bus,
e.g. pca953x. In that case, gpio-reset needs to be ready before I2C
bus driver which is generally ready at subsys_initcall time. Let's
register gpio-reset driver in arch_initcall() to have it ready early
enough.The defer probe mechanism is not used here, because a reset controller
driver should be reasonably registered early than other devices. More
importantly, defer probe doe not help in some nasty cases, e.g. the
gpio-pca953x device itself needs a reset from gpio-reset driver start
working.[shawn.guo: cherry-pick commit 7153f05108ef from imx_3.10.y]

After the retirement of MACH_PISTACHIO, the Pistachio Reset Driver is no
longer auto-enabled when building a kernel for Pistachio systems.
Worse, the driver cannot be enabled by the user at all (unless
compile-testing), as the config symbol is invisible.Fix this partially by making the symbol visible again when compiling for
MIPS, and dropping the useless default. The user still has to enable
the driver manually when building a kernel for Pistachio systems,
though.Fixes: 104f942b2832ab13 ("MIPS: Retire MACH_PISTACHIO")
