This is a follow-up series to "BCM2711's sdhci-iproc CMD timeouts"[1], but since much most of the patches changed I decided to start counting patch revisions from scratch. This series tries to address rather odd behavior from BCM2711's integration of sdhci-iproc (Raspberry Pi 4's SoC). The controller will timeout on SDHCI CMDs under the following conditions: - No SD card plugged in (the card polling thread is running, CD irq disabled). - BCM2711's VPU clock configured at 500MHz or more, lower clocks are OK. There is no specific command that will time out, it seems random. As an extra to this I also include a small fix, and convert the controller's bindings to yaml.
