|/ | | | | | | | | | | | | | | | | | TI aemif driver creates its own subnodes of the device tree in order to guarantee that all child devices are probed after the AEMIF timing parameters are configured. Some devices (e.g. da850) use struct of_dev_auxdata for clock lookup but nodes created from within the aemif driver can't access the lookup table.

|/ | | | | | | | | | | | | | | | | | A recent commit (inadvertently?) changed how failed probe of a gpmc child node was handled. Instead of proceeding with setting up any other children as before, a single error now aborts the whole process. This change broke networking on some Overo boards due to probe failing for an unrelated nand node. This second issue should obviously be fixed, but let's restore the old behaviour of allowing child-node probe to fail to avoid further similar breakage on other systems.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | The EBI (External Bus Interface) is used to access external peripherals (NOR, SRAM, NAND, and other specific devices like ethernet controllers). Each device is assigned a CS line and an address range and can have its own configuration (timings, access mode, bus width, ...). This driver provides a generic DT binding to configure a device according to its requirements. For specific device controllers (like the NAND one) the SMC timings should be configured by the controller driver through the matrix and smc syscon regmaps.

| | |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Mediatek SMI has two generations of HW architecture, mt8173 uses the second generation of SMI HW while mt2701 uses the first generation HW of SMI. There's slight differences between the two generations, for generation 2, the register which control the iommu port access PA or IOVA is at each larb's register base. But for generation 1, the register is at smi ao base(smi always on register base). Besides that, the smi async clock should be prepared and enabled for SMI generation 1 HW to transform the smi clock into emi clock domain, but is not needed for SMI generation 2. This patch add SMI driver for mt2701 which use generation 1 SMI HW. Signed-off-by: Honghui Zhang <honghui.zhang@mediatek.com> Signed-off-by: Joerg Roedel <jroedel@suse.de>

As a consequence, the memory accesses cannot be configured properly when the extra delay are needed for OE and WE. Fix the update of GPMC_CONFIG4_WEEXTRADELAY with the value from the device tree file and prevents GPMC_CONFIG4_OEXTRADELAY being overwritten by the WEXTRADELAY value from the device tree.
