Merge tag 'imx-fixes-4.18' of git://git.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux into fixes
i.MX fixes for 4.18:
- Fix i.MX6SX PCIe MSI interrupt number, so that MSI IRQs can be
properly propagated to the upstream interrupt controller.
- Fix GPCv2 MIPI/PCIe/USB_HSIC's PGC offset. The values in Reference
Manual are incorrect.
- Correct SDMA setting for i.MX6Q SPI5 device to fix the issue, that
the SPI controller RX FIFO was not empty after a DMA transfer, and
the driver gets stuck in the next PIO transfer when reading one word
more than expected.
