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

2022-04-27T11:53:52+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: socfpga: add empty driver allowing consumers to probe

2021-11-18T13:03:42+00:00

[ Upstream commit 3ad60b4b3570937f3278509fe6797a5093ce53f8 ]

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: brcmstb-rescal: fix incorrect polarity of status bit

2021-11-02T18:48:22+00:00

commit f33eb7f29c16ba78db3221ee02346fd832274cdd upstream.

The readl_poll_timeout() should complete when the status bit
is a 1, not 0.

reset: reset-zynqmp: Fixed the argument data type

[ Upstream commit ed104ca4bd9c405b41e968ad4ece51f6462e90b6 ]

This patch changes the data type of the variable 'val' from
int to u32.

Addresses-Coverity: argument of type "int *" is incompatible with parameter of type "u32 *"

reset: ti-syscon: fix to_ti_syscon_reset_data macro

2021-07-25T12:36:11+00:00

[ Upstream commit 05cf8fffcdeb47aef1203c08cbec5224fd3a0e1c ]

The to_ti_syscon_reset_data macro currently only works if the
parameter passed into it is called 'rcdev'.

Fixes a checkpatch --strict issue:

  CHECK: Macro argument reuse 'rcdev' - possible side-effects?
  #53: FILE: drivers/reset/reset-ti-syscon.c:53:

reset: brcmstb: Add missing MODULE_DEVICE_TABLE

[ Upstream commit e207457f9045343a24d936fbb67eb4b412f1c6ad ]

This patch adds missing MODULE_DEVICE_TABLE definition which generates
correct modalias for automatic loading of this driver when it is built
as an external module.

[ Upstream commit 466ba3c8ff4fae39e455ff8d080b3d5503302765 ]

The driver defined of_device_id table but did not use it with
of_match_table.  This prevents usual matching via devicetree and causes
a W=1 warning:

[ Upstream commit 6ab9d6219f86f0db916105444813aafce626a2f4 ]

The Intel Gateway reset controller is only present on Intel Gateway
platforms.  Hence add a dependency on X86, to prevent asking the user
about this driver when configuring a kernel without Intel Gateway
support.

[ Upstream commit 42f6a76fbe85e5243f83a3ed76809b1ebbb7087e ]

The Broadcom STB RESCAL reset controller is only present on Broadcom
BCM7216 platforms.  Hence add a dependency on ARCH_BRCMSTB, to prevent
asking the user about this driver when configuring a kernel without
BCM7216 support.

Also, merely enabling CONFIG_COMPILE_TEST should not enable additional
code, and thus should not enable this driver by default.
