Merge branch 'spi-5.2' into spi-next (2019-05-02 11:20:29 +0900)
----------------------------------------------------------------
spi: Updates for v5.2
One small feature was added this release but the bulk of the diffstat
and the changelog comes from the fact that several older drivers got
some fairly hefty reworks and a couple of new drivers were added:
- Support for detailed control of timing around chip selects from
Sowjanya Komatineni.
- A big set of fixes and imrovements for the Tegra114 driver from
Sowjanya Komatineni.
- A big simplification of the GPIO driver from Andrey Smirnov.
- DMA support and fixes for the Freescale LPSPI driver from Clark Wang.
- Fixes and optimizations for the bcm2835aux from Martin Sparl.
- New drivers for Mediatek MT7621 (graduated from staging) and Zynq QSPI.
