firmware: tegra: Fix error return code in tegra210_bpmp_init()

2021-07-20T14:10:52+00:00

[ Upstream commit 7fea67710e9f6a111a2c9440576f2396ccd92d57 ]

When call irq_get_irq_data() to get the IRQ's irq_data failed, an
appropriate error code -ENOENT should be returned. However, we directly
return 'err', which records the IRQ number instead of the error code.

firmware/tegra: Enable Tegra186 BPMP support on Tegra194

2019-02-07T17:52:39+00:00

The BPMP implementation on Tegra194 is mostly compatible with the
implementation on Tegra186, so make sure the latter is available when
support for Tegra194 is enabled.

firmware: tegra: Conditionally support SoC generations

2019-02-07T17:52:19+00:00

Only include support for Tegra210 and Tegra186 in the BPMP driver if
support for those SoCs was selected. This fixes a build failure seen
on 32-bit ARM allmodconfig builds, but could also happen on 64-bit
ARM builds if either Tegra210 or Tegra186 were not selected.
