If anyone has any objections, please let me know. ------------------ From: Lad Prabhakar [ Upstream commit 3db1fb5e1bb4c9eefc554f985f6f3316fa1292e5 ] Add XSPI_CDD1BUF0 to the xSPI regmap volatile register table. XSPI_CDD1BUF0 is a data buffer register used during manual transfers and, like XSPI_CDD0BUF0, its contents are transient and should not be cached by regmap. Mark it as volatile so reads always access the hardware register.
