Twelfth time's the charm.

This patch series depends on the series "media: rkisp1: Fix shared
interrupt handling" [1]

This series extends the rkisp1 driver to support the ISP found in the

The ISP IP cores in the Rockchip RK3399 (known as the "Rockchip ISP1")
and in the NXP i.MX8MP have the same origin, and have slightly diverged
over time as they are now independently developed (afaik) by Rockchip
and VeriSilicon. The latter is marketed under the name "ISP8000Nano",
and is close enough to the RK3399 ISP that it can easily be supported by
the same driver.

Patches 9 and 10 add support for UYVY output format, which can be
implemented on the ISP version in the i.MX8MP but not in the one in the

This version of the series specifically has been tested on a Polyhex
Debix model A with an imx219 (Raspberry Pi cam v2).

v6 added patch 11 to fix endinanness issues on raw streams on the

In v12 patch 6 "media: rkisp1: Add version enum for i.MX8MP ISP" has
been split out from patch 12 "media: rkisp1: Add match data for i.MX8MP
