+Subject: [PATCH] media: i2c: imx290: Add support for test pattern
+ generation
+
+Commit a58df1f9e4885eaf3d0663574a217e513821a9f0 upstream.
+
+Add support for generating following test patterns by IMX290:
+
+* Sequence Pattern 1
+* Horizontal Color-bar Chart
+* Vertical Color-bar Chart
+* Sequence Pattern 2
+* Gradation Pattern 1
+* Gradation Pattern 2
+* 000/555h Toggle Pattern
