Subject: [PATCH v3 00/46] media: rkisp1: Cleanups to prepare for i.MX8MP support
Date: Mon, 11 Jul 2022 15:42:02 +0300	[thread overview]
Message-ID: <20220711124248.2683-1-laurent.pinchart@ideasonboard.com> (raw)

Hello,

This series cleans up, reworks and extends the rkisp1 driver to prepare
for support of the ISP found in the NXP i.MX8MP SoC.

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 (as far as I
understand) 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.

This series starts with a few changes to the V4L2 async framework
(01/46) and MC core helpers (02/46 to 04/46) to support the rest of the
changes. It continues with various cleanups and reworks in order to
support CSI-2 receivers external to the ISP as found in the i.MX8MP
(05/46 to 45/46). Patch 46/46 is a small additional debugging improvement.

Compared to v2, i.MX8MP support has been left out as a few issues still
need to be solved. This preparatory series targets v5.20, while i.MX8MP
support will be for v5.21. Review comments have been taken into account.

Dafna, only patches 38/46, 39/46 and 46/46 are missing your reviews.
Would you be able to have a look ?
