+Subject: [PATCH] dtoverlays: Add an overlay for the Infineon IRS1125
+
+The Infineon IRS1125 is a CSI2 time of flight depth sensor
+which has a suitable V4L2 subdevice driver.
+
+Add an overlay for configuring it.

++Name: irs1125
++Info: Infineon irs1125 TOF camera module.
++ Uses Unicam 1, which is the standard camera connector on most Pi
++ variants.
++Load: dtoverlay=irs1125,<param>=<val>
++Params: i2c_pins_0_1 Use pins 0&1 for the I2C instead of 44&45.
++ Useful on Compute Modules.
++
++ i2c_pins_28_29 Use pins 28&29 for the I2C instead of 44&45.
++ This is required for Pi B+, 2, 0, and 0W.
++
++
+ Name: jedec-spi-nor
+ Info: Adds support for JEDEC-compliant SPI NOR flash devices. (Note: The
+ "jedec,spi-nor" kernel driver was formerly known as "m25p80".)
