Subject: [PATCH v2 11/13] media: platform: mediatek: add isp_7x build config

From: "shangyao.lin" <shangyao.lin@...iatek.com>

Add Kconfig and Makefile to include MTK ISP CAMSYS, integrating the driver into
the kernel build and configuration process.

Question for CK:

Hi CK,

Thank you for your review and comments.

Just to confirm, do you mean that when I add mtk_cam-seninf-route.c and
mtk_cam-seninf-drv.c in patch [3/10], I should also create or update the
corresponding Makefile to ensure these two .c files are compiled as part of the
driver? Is my understanding correct?

Thank you for your clarification.

Best regards,
Shangyao
