Hello, This patch series adds a new driver for the THine THP7312 ISP. It has been tested on an OLogic Pumpkin i350, which has a Mediatek MT8365 SoC, with the THine THSCG101 camera module. Technically the driver itself (and its bindings) have no dependencies, but to run/test this on the Pumpkin i350 with the mainline kernel, a number of patches are needed to support the board and the MT8365 SoC. Some of those patches are on their way to mainline, and some, like the Pumpkin i350 board device tree, will require more work. For convenience and reference, the needed patches are available in [1]. Example overlays for DT integration of the THP7312 are available in that branch, in arch/arm64/boot/dts/mediatek/mt8365-pumpkin-csi0-thp7312-imx258.dtso and arch/arm64/boot/dts/mediatek/mt8365-pumpkin-csi1-thp7312-imx258.dtso. Compared to v7, usage of an uninitialized variable, reported by smatch, has been fixed. The series is based on top of the latest media tree, with all the V4L2 dependencies finally merged for v6.8. The driver still depends on the "[RESEND PATCH v4 1/1] device property: Add fwnode_name_eq()" path previously submitted to the linux-media mailing list ([2]), which I will include in the pull request. If anyone wants to check it out, the tag I will use for the pull request is available from [3].
