Pull spi updates from Mark Brown: "The main focus of this release from a framework point of view has been spi-mem where we've acquired support for a few new hardware features which enable better performance on suitable hardware. Otherwise mostly thanks to Arnd's cleanup efforts on old platforms we've removed several obsolete drivers which just about balance out the newer drivers we've added this cycle. Summary: - Allow drivers to flag if they are unidirectional. - Support for DTR mode and hardware acceleration of dummy cycles in spi-mem. - Support for Allwinder H616, Intel Lightning Mountain, nVidia Tegra QuadSPI, Realtek RTL838x and RTL839x. - Removal of obsolete EFM32, Txx9 and SIRF Prima and Atlas drivers" * tag 'spi-v5.12' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi: (76 commits) spi: Skip zero-length transfers in spi_transfer_one_message() spi: dw: Avoid stack content exposure spi: cadence-quadspi: Use spi_mem_dtr_supports_op() spi: spi-mem: add spi_mem_dtr_supports_op() spi: atmel-quadspi: Disable the QSPI IP at suspend() spi: pxa2xx: Add IDs for the controllers found on Intel Lynxpoint spi: pxa2xx: Fix the controller numbering for Wildcat Point spi: Change provied to provided in the file spi.h spi: mediatek: add set_cs_timing support spi: support CS timing for HW & SW mode spi: add power control when set_cs_timing spi: stm32: make spurious and overrun interrupts visible spi: stm32h7: replace private SPI_1HZ_NS with NSEC_PER_SEC spi: stm32: defer probe for reset spi: stm32: driver uses reset controller only at init spi: stm32h7: ensure message are smaller than max size spi: stm32: use bitfield macros spi: stm32: do not mandate cs_gpio spi: stm32: properly handle 0 byte transfer spi: clps711xx: remove redundant white-space ...

dt-bindings: Add missing array size constraints

2021-01-11T23:42:25Z

DT properties which can have multiple entries need to specify what the entries are and define how many entries there can be. In the case of only a single entry, just 'maxItems: 1' is sufficient. Add the missing entry constraints. These were found with a modified meta-schema. Unfortunately, there are a few cases where the size constraints are not defined such as common bindings, so the meta-schema can't be part of the normal checks.
