reset: tegra-bpmp: Restore Handle errors in BPMP response

2022-04-27T12:38:55+00:00

[ Upstream commit d1da1052ffad63aa5181b69f20a6952e31f339c2 ]

This reverts following commit 69125b4b9440 ("reset: tegra-bpmp: Revert
Handle errors in BPMP response").

The Tegra194 HDA reset failure is fixed by commit d278dc9151a0 ("ALSA:
hda/tegra: Fix Tegra194 HDA reset failure"). The temporary revert of
original commit c045ceb5a145 ("reset: tegra-bpmp: Handle errors in BPMP
response") can be removed now.

reset: renesas: Check return value of reset_control_deassert()

2022-04-27T12:38:55+00:00

[ Upstream commit da18980a855edf44270f05455e0ec3f2472f64cc ]

Deasserting the reset is vital, therefore bail out in case of error.

reset: renesas: Fix Runtime PM usage

2022-01-11T14:35:16+00:00

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.

reset: tegra-bpmp: Revert Handle errors in BPMP response

2021-12-22T08:32:33+00:00

commit 69125b4b9440be015783312e1b8753ec96febde0 upstream.

Commit c045ceb5a145 ("reset: tegra-bpmp: Handle errors in BPMP
response") fixed an issue in the Tegra BPMP error handling but has
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")
while a fix for the Tegra HDA driver is created.

reset: socfpga: add empty driver allowing consumers to probe

2021-10-05T10:23:16+00:00

The early reset driver doesn't ever probe, which causes consuming
devices to be unable to probe. Add an empty driver to set this device
as available, allowing consumers to probe.

reset: tegra-bpmp: Handle errors in BPMP response

2021-10-05T08:55:18+00:00

The return value from tegra_bpmp_transfer indicates the success or
failure of the IPC transaction with BPMP. If the transaction
succeeded, we also need to check the actual command's result code.
Add code to do this.

reset: pistachio: Re-enable driver selection

2021-10-05T08:49:40+00:00

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.
