Merge tag 'imx-soc-4.12' of... 

Merge tag 'imx-soc-4.12' of git://git.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux into next/soc

i.MX SoC changes for 4.12:
 - A correction on mmdc_pmu_write_accesses event definition.
 - Add new axi_id perf command to support MMDC filter memory usage
   profiling.
 - Set correct SPI chip_select in platform device registration, so that
   spi-imx driver code can be improved to use chip_select directly for
   harwdare setup instead of indirectly via the cs_gpio mapping array.
 - Disable APIS bus supervisor protect for i.MX25, since the default
   configuration doesn't work for a few peripherals accessed through
   SDMA.
 - Add compatible check for the secondary generation of I2SE i.MX28
   Duckbill board support.
