| Subject: ARM: dts: meson8b: use the actual frequency for the GPU's 364MHz OPP |
| |
| From: Martin Blumenstingl <martin.blumenstingl@googlemail.com> |
| |
| commit c3dd3315ab58b2cfa1916df55b0d0f9fbd94266f upstream. |
| |
| The clock setup on Meson8 cannot achieve a Mali frequency of exactly |
| 182.15MHz. The vendor driver uses "FCLK_DIV7 / 1" for this frequency, |
| which translates to 2550MHz / 7 / 1 = 364285714Hz. |
| Update the GPU operating point to that specific frequency to not confuse |
| myself when comparing the frequency from the .dts with the actual clock |
| rate on the system. |
| |
| Fixes: c3ea80b6138cae ("ARM: dts: meson8b: add the Mali-450 MP2 GPU") |
