soc/tegra: fuse: Fix bitwise vs. logical OR warning

2021-12-22T08:29:37Z

[ Upstream commit a7083763619f7485ccdade160deb81737cf2732f ] A new warning in clang points out two instances where boolean expressions are being used with a bitwise OR instead of logical OR: drivers/soc/tegra/fuse/speedo-tegra20.c:72:9: warning: use of bitwise '|' with boolean operands [-Wbitwise-instead-of-logical] reg = tegra_fuse_read_spare(i) | ^~~~~~~~~~~~~~~~~~~~~~~~~~ || drivers/soc/tegra/fuse/speedo-tegra20.c:72:9: note: cast one or both operands to int to silence this warning drivers/soc/tegra/fuse/speedo-tegra20.c:87:9: warning: use of bitwise '|' with boolean operands [-Wbitwise-instead-of-logical] reg = tegra_fuse_read_spare(i) | ^~~~~~~~~~~~~~~~~~~~~~~~~~ || drivers/soc/tegra/fuse/speedo-tegra20.c:87:9: note: cast one or both operands to int to silence this warning 2 warnings generated. The motivation for the warning is that logical operations short circuit while bitwise operations do not. In this instance, tegra_fuse_read_spare() is not semantically returning a boolean, it is returning a bit value. Use u32 for its return type so that it can be used with either bitwise or boolean operators without any warnings.

soc/tegra: fuse: Fix build with Tegra194 configuration

2020-03-05T15:43:39Z

[ Upstream commit 6f4ecbe284df5f22e386a640d9a4b32cede62030 ] If only Tegra194 support is enabled, the tegra30_fuse_read() and tegra30_fuse_init() function are not declared and cause a build failure. Add Tegra194 to the preprocessor guard to make sure these functions are available for Tegra194-only builds as well.

soc/tegra: fuse: Do not log error message on deferred probe

2019-06-05T07:54:13Z

Recent changes have made it much more probable that clocks are not available yet when the FUSE driver is first probed. However, that is a situation that the driver can cope with just fine. To avoid confusion, don't output an error when this happens. Signed-off-by: Thierry Reding
