| Summary | 0001186: Fix max_speed_hz computation for S3C64XX SPI | ||||
| Description | The computation for the maximum possible speed in drivers/spi/spi-s3c64xx.c is too complicated and could be wrong in some cases. | ||||

Don't AND with PSR_MASK, but check for greater than instead. Using AND could cause wrong results if the remaining value was again rather small. In addition we can use a computation that directly computes the desired psr. We don't need to recompute the resulting speed and then adjust psr if too high. |
