| Subject | [PATCH v7 6/9] ARM: dts: am335x: Disable wait pin monitoring for NAND |
| Message-ID | <r5oae-7Zs-9@gated-at.bofh.it> |
The NAND Ready/Busy# line is connected to GPMC_WAIT0 pin and can't be used for wait state insertion for NAND I/O read/write. So disable read/write wait monitoring as per Reference Manual's suggestion [1].
