| Subject: ARM: dts: meson8: use the actual frequency for the GPU's 182.1MHz OPP |
| |
| From: Martin Blumenstingl <martin.blumenstingl@googlemail.com> |
| |
| commit fe634a7a9a57fb736e39fb71aa9adc6448a90f94 upstream. |
| |
| The clock setup on Meson8 cannot achieve a Mali frequency of exactly |
| 182.15MHz. The vendor driver uses "FCLK_DIV7 / 2" for this frequency, |
| which translates to 2550MHz / 7 / 2 = 182142857Hz. |
| 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. |
| |
