Subject: [PATCH v4 0/6] media: qcom: iris: encoder feature enhancements
batch2
Hi All,
This patch series introduces several enhancements to the Qualcomm Iris
encoder driver, improving support for V4L2 controls and enabling more
video encoding features.
All patches have been tested with v4l2-compliance and v4l2-ctl on
gen1:SM8250, QCS6490, gen2:QCS8300, QCS8550, QCS9100, X1E-80100.
