Build results:
	total: 159 pass: 159 fail: 0
Qemu test results:
	total: 455 pass: 454 fail: 1
Failed tests:
	arm:sabrelite:multi_v7_defconfig:mtd2:mem256:net,default:imx6dl-sabrelite:rootfs

As far as I can see, the second SPI interface fails to instantiate.

[   21.491528] spi_imx 2008000.spi: bitbang start failed with -22

There are also various new warnings in clock code.

[   21.492631] WARNING: CPU: 0 PID: 1 at drivers/clk/clk.c:986 clk_core_disable+0x124/0x2e4
[   21.497524] WARNING: CPU: 0 PID: 1 at drivers/clk/clk.c:845 clk_core_unprepare+0x268/0x388

The warnings in clock code are gone after reverting all changes introducing
PM support for imx spi code. The boot failure is gone after reverting the
gpio conversion. In total, I reverted the following patches to fix the
boot and warning problems.

d6fcaa127cc6 Revert "spi: imx/fsl-lpspi: Convert to GPIO descriptors"
9783b21b591d Revert "spi: imx: enable runtime pm support"
4a8bdbf7462b Revert "spi: spi-imx: using pm_runtime_resume_and_get instead of pm_runtime_get_sync"
e6c5f497ff35 Revert "spi: imx: Don't skip cleanup in remove's error path"
d6ea758df74f Revert "spi: imx: fix runtime pm support for !CONFIG_PM"
b9dbd028c970 Revert "spi: imx: fix reference leak in two imx operations"

Is this really 5.4 material ?
