| Subject: firmware: tegra: Fix IVC dependency problems |
| |
| From: Thierry Reding <treding@nvidia.com> |
| |
| [ Upstream commit 78eb18020a88a4eed15f5af7700ed570642ff8f1 ] |
| |
| The IVC code is library code that other drivers need to select if they |
| need that library. However, if the symbol is user-selectable this can |
| lead to conflicts. |
| |
| Fix this by making the symbol only selectable for COMPILE_TEST and add |
| a select TEGRA_IVC to TEGRA_BPMP, which is currently the only user. |
