While most display helpers Kconfig symbols have the DRM_DISPLAY prefix, the DisplayPort AUX bus implementation uses DRM_DP_AUX_BUS. Since the number of users is limited and it's a selected symbol, we can easily rename it to make it consistent. Reviewed-by:

In response to my patch removing the "wait for HPD" logic at the beginning of the MSM DP transfer() callback [1], we had some debate about what the "This is an optional function" meant in the documentation of the wait_hpd_asserted() callback. Let's clarify. As talked about in the MSM DP patch [1], before wait_hpd_asserted() was introduced there was no great way for panel drivers to wait for HPD in the case that the "built-in" HPD signal was used. Panel drivers could only wait for HPD if a GPIO was used. At the time, we ended up just saying that if we were using the "built-in" HPD signal that DP AUX controllers needed to wait for HPD themselves at the beginning of their transfer() callback. The fact that the wait for HPD at the beginning of transfer() was awkward/problematic was the whole reason wait_hpd_asserted() was added. Let's make it obvious that if a DP AUX controller implements wait_hpd_asserted() that they don't need a loop waiting for HPD at the start of their transfer() function. We'll still allow DP controllers to work the old way but mark it as deprecated. [1] https://lore.kernel.org/r/20240315143621.v2.3.I535606f6d4f7e3e5588bb75c55996f61980183cd@changeidReviewed-by:

In case the LCDIF is enabled in DT but unused, the clocks used by the LCDIF are not enabled. Those clocks may even have a use count of 0 in case there are no other users of those clocks. This can happen e.g. in case the LCDIF drives HDMI bridge which has no panel plugged into the HDMI connector. Do not attempt to disable clocks in the suspend callback and re-enable clocks in the resume callback unless the LCDIF is enabled and was in use before the system entered suspend, otherwise the driver might end up trying to disable clocks which are already disabled with use count 0, and would trigger a warning from clock core about this condition. Note that the lcdif_rpm_suspend() and lcdif_rpm_resume() functions internally perform the clocks disable and enable operations and act as runtime PM hooks too. Reviewed-by:

If a specific design doesn't wire IT66121's interrupt signal output pin up to the display controller side, then we should not register the interrupt handler. Such a decision is valid usage, as we can fall back to polling mode. So, don't make the assumption that a specific board always supports HPD. Carry out a sanity check on 'client->irq' before using it, fall back to polling mode if client->irq < 0 is true. Such a design increases the overall flexibility. Signed-off-by:

As it turns out, this is because we're currently not returning the correct variable when r535_dp_aux_xfer() hits an error - causing us to never propagate GSP errors for failed aux transactions to userspace.
