[PATCH v2 00/14] spi: bcm63xx-hsspi: driver and doc updates

[William Zhang]

This patch series include the accumulative updates and fixes for the
driver from Broadcom. It also added a new driver for the updated SPI
controller found in the new BCMBCA SoC. The device tree document is
converted to yaml format and updated accordingly.

Changes in v2:
- Update the dts yaml document and all the related dtsi/dts accordingly
- Fix build error for Alpha platform
- Add a new patch for bcm63xx-hsspi driver to support the new compatible 
string
- Make interrupt mode required but keep polling mode as default. Also 
add a sysfs option wait_mode for run-time mode change 
- Remove use_cs_workaround option and change the transfer logic to try 
prepend mode first and if not prependable, switch to dummy cs mode with 
clock limit at the 25MHz. Add driver sysfs node xfer_mode for run-time 
configuration to dummy cs or prepend mode.
- Withdraw SPI device specific clock gate option patch for now
