Merge tag 'spi-v6.12' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi

Pull spi updates from Mark Brown:
 "This is quite a quiet release for SPI. The one new core feature here
  is support for configuring the state of the MOSI pin when the bus is
  idle, there are some devices which are very fragile in this regard
  even when the chip select signal is not asserted. Otherwise we have
  some new driver support, a bunch of small fixes and some general
  cleanup work.

   - Support for configuring the state of the MOSI pin when the the bus
     is idle

   - Add the Elgin JG0309-01 in spidev

   - Support for Marvell xSPI, Mediatek MTK7981, Microchip PIC64GX, NXP
     i.MX8ULP, and Rockchip RK3576 controllers

  I also accidentally pulled in an IIO DT bindings update due to a typo
  when applying the MOSI idle state patches"
