| Subject: video: fbdev: Set pixclock = 0 in goldfishfb |
| |
| [ Upstream commit ace6033ec5c356615eaa3582fb1946e9eaff6662 ] |
| |
| User space Android code identifies pixclock == 0 as a sign for emulation |
| and will set the frame rate to 60 fps when reading this value, which is |
| the desired outcome. |
