Subject: [PATCH v1 0/9] spi: pxa2xx: Convert to use SPI core GPIO handling

Convert the PXA2xx SPI host controller driver to use SPI core GPIO handling.
On top of that a few additional cleanups.

Has been tested on Intel Merrifield with SPI ADC and TFT display connected.

Andy Shevchenko (9):
  spi: pxa2xx: Propagate firmware node to the child SPI controller
    device
  spi: pxa2xx: Switch to use SPI core GPIO (descriptor) CS handling
  spi: pxa2xx: Switch to use SPI core GPIO (legacy) CS handling
  spi: pxa2xx: Drop duplicate chip_select in struct chip_data
  spi: pxa2xx: Drop unneeded '!= 0' comparisons
  spi: pxa2xx: Fix printf() specifiers
  spi: pxa2xx: Fix style of and typos in the comments and messages
  spi: pxa2xx: Update documentation to point out that it's outdated
  spi: pxa2xx: Use predefined mask when programming FIFO thresholds
