The commit sets CONFIG_ZTEST_STACK_SIZE to 4096. Fixes #79801 Signed-off-by: Dominik Ermel <[email protected]> (cherry picked from commit 3e8ea52)

…trollers Add a generic driver for MSPI controllers based on the DesignWare SSI core. With small vendor-specific adaptations covering integration details, it should be possible to use the driver for various devices. Upstream PR #: 80042 Signed-off-by: Andrzej Głąbek <[email protected]>
…devices Add a flash driver intended to handle various flash devices connected over MSPI bus as long as they support JEDEC SFDP. This is an initial commit providing only basic operations in Octal I/O mode with some hard-coded values for Macronix MX25Ux series chips. Upstream PR #: 80042 Signed-off-by: Andrzej Głąbek <[email protected]>
This is a follow-up to commit 45d827a. Although routing for those pins is configured via UICR, pinctrl still needs to be involved so that it is possible to set desired drive mode for them etc. Add also the missing RWDS pin. Upstream PR #: 80042 Applied as a [nrf noup] due to a conflict. Signed-off-by: Andrzej Głąbek <[email protected]>

This is a follow-up to commit cdf45cb234077522b5cef2da084869af43d42dc1. Adjust the DTS node for the nRF EXMIF peripheral so that it is possible to handle the peripheral with the generic MSPI driver for DW SSI based controllers and use all its data lines in communication. Also adjust the related board files accordingly. Upstream PR #: 80042 Signed-off-by: Andrzej Głąbek <[email protected]>
…option changes It is no longer needed to enable a specific flash driver in the sample configuration. An appropriate driver (together with its dependencies, like the SPI bus) for a given target will be enabled automatically based on what is enabled in DTS.

Add a generic driver for controllers based on the Designware SSI core.
With small vendor-specific adaptations covering integration details,
it should be possible to use it for many devices.
