media: v4l2-common: Add legacy camera sensor clock helper

2025-09-09T13:59:19Z

The recently introduced devm_v4l2_sensor_clk_get() helper aims at simplifying sensor drivers by centralizing clock handling code, as well as reducing cargo-cult and deprecated behaviour. A set of drivers implement external clock handling in a non-standard way. This can't be changed as there is a high risk of breaking existing platforms, but keeping the code as-is creates a risk of new drivers copying deprecated behaviour. To fix this, introduce a new devm_v4l2_sensor_clk_get_legacy() helper and use it in those driver. Compared to devm_v4l2_sensor_clk_get(), the new helper takes the "clock-frequency" property into account and sets the external clock rate on OF platforms, and adds the ability to specify a fixed default or fallback clock rate in case the "clock-frequency" property is not present.

media: cadence: cdns-csi2rx: Support multiple pixels per clock cycle

2025-08-25T13:40:42Z

The output pixel interface is a parallel bus (32 bits), which supports sending multiple pixels (1, 2 or 4) per clock cycle for smaller pixel widths like RAW8-RAW16. Dual-pixel and Quad-pixel modes can be a requirement if the export rate of the Cadence IP in Single-pixel mode maxes out before the maximum supported DPHY-RX frequency, which is the case with TI's integration of this IP [1]. So, we export a function that lets the downstream hardware block request a higher pixel-per-clock on a particular output pad. We check if we can support the requested pixels per clock given the known maximum for the currently configured format. If not, we set it to the highest feasible value and return this value to the caller.
