Subject: [PATCH v4 0/4] media: imx-jpeg: Add v1 hardware encoder support for i.MX952

From: Ming Qian <ming.qian@....nxp.com>

Support the upgraded JPEG encoder v1 found on i.MX952 SoC.

V1 hardware uses enhanced descriptors with mode, quality, and
threshold fields, configured in a single phase via setup_desc
callback.
V0 hardware continues using the existing two-phase manual configuration.
