[PATCH v2 0/5] spi: atmel-quadspi: add support for LAN969x

[Robert Marko]

This series adds QSPI support for the Microchip LAN969x which has two QSPI
controllers based on SAMA7G5.

It requires pad calibration, supports DMA, and supports 100 MHz operation.

It requires a different init sequence to SAMA7G5 so support for custom
.init per controller caps is added, and existing controllers relying on
checking gclk are converted to it.

Changes in v2:
* Make the DTS nodes apply on top of next-20260708, as SDMMC is not yet upstream
