[PATCH v2 0/7] media: synopsys: enhancements and i.MX95 support

This series enhances the Synopsys DesignWare MIPI CSI-2 receiver driver
with multiple stream support and adds i.MX95 platform support.

The i.MX95 variant is similar to i.MX93 but uses IDI instead of IPI. Since
IDI is software transparent, only a different register map is needed.

Tested on i.MX93 and i.MX95 platforms.

Changes in v2:
- Add two new patches
- Simplify error handling by keeping goto labels instead of early returns
- Removes redundant register availability check
- Uses read_poll_timeout() with dw_mipi_csi2rx_read() instead of
readl_poll_timeout() with direct register address
- Fixes stopstate condition logic
- Check PHY stopstate after sensor enable instead of before to ensure
correct timing.
- Optimize PHY stopstate polling parameters (1000us->10us, 2s->1ms) to
balance performance and responsiveness.
- Add dedicated constraint block for i.MX95 to reflect different clock
requirements (only per clock needed vs i.MX93 which needs both per and
pixel clocks)
- Update commit message to include more details about interface differences
- Add Reviewed-by tag from Frank Li <Frank.Li@nxp.com>
- Update commit message
- See each patch's changelog for details.
- Link to v1: https://lore.kernel.org/r/20260415-csi2_imx95-v1-0-7d63f3508719@oss.nxp.com
