-Subject: [PATCH] media: aspeed: add a workaround to fix a silicon bug
-
-AST2500 silicon revision A1 and A2 have a silicon bug which causes
-extremly long capturing time on specific resolutions (1680 width).
-To fix the bug, this commit adjusts the capturing window register
-setting to 1728 if detected width is 1680. The compression window
-register setting will be kept as the original width so output
-result will be the same.
