Intel Merrifield SPI is actually more closer to PXA3xx. It has extended FIFO (32 bytes) and additional registers to get or set FIFO thresholds. Introduce new type for Intel Merrifield SPI host controllers and handle bigger FIFO size. Signed-off-by:

Originally, the Renesas RZ/N1 SPI Controller DT bindings were not integrated in the main DT bindings for the Synopsys DesignWare Synchronous Serial Interface, but in its own file, as the RZ/N1 controller has additional registers for software CS control and DMA. As so far DMA is not supported on RZ/N1, and json-schema can handle any possible differences fine, integrate the RZ/N1 compatible values in the main DT bindings for the Synopsys DW SSI.

Commit b9d79e4c ("fbmem: Mark proc_fb_seq_ops as __maybe_unused") places the '__maybe_unused' in an entirely incorrect location between the "struct" keyword and the structure name. It's a wonder that gcc accepts that silently, but clang quite reasonably warns about it: drivers/video/fbdev/core/fbmem.c:736:21: warning: attribute declaration must precede definition [-Wignored-attributes] static const struct __maybe_unused seq_operations proc_fb_seq_ops = { ^ Fix it.
