| Subject: media: i2c: ov01a10: Fix reported pixel-rate value |
| |
| From: Hans de Goede <hansg@kernel.org> |
| |
| [ Upstream commit 9c632eebf6af4cb7b0f85503fe1ebc5176ff0db1 ] |
| |
| CSI lanes are double-clocked so with a single lane at 400MHZ the resulting |
| pixel-rate for 10-bits pixels is 400 MHz * 2 / 10 = 80 MHz, not 40 MHz. |
| |
| This also matches with the observed frame-rate of 60 fps with the default |
| vblank setting: 80000000 / (1488 * 896) = 60. |
