[PATCH v1 0/2] tests/kms_hdmi_inject: Add low refresh rate subtests

[Mohammed Bilal <mohammed.bilal@intel.com>]

This series adds two subtests to validate low refresh rate (11Hz, 10Hz,
5Hz, 4Hz) mode handling on HDMI connectors. The tests verify driver
behavior around the hardware minimum pixel clock threshold (34.38 MHz).

Patch 1 adds a positive test that validates low refresh rates are
achievable when pixel clock is maintained at the hardware minimum by
adjusting vtotal.

Patch 2 adds a negative test that validates the driver correctly rejects
modes when the standard pixel clock calculation drops below the hardware
minimum.

Together these tests ensure the driver properly enforces hardware
constraints while still supporting valid low refresh rate configurations.
