[PATCH v2 0/7] spi: zynq-qspi: Clarify and fix the chip selection

[Miquel Raynal <miquel.raynal@xxxxxxxxxxx>]

Hello,

While working on SPI-NOR support I figured the chip select handling of
the Zynq 7000 QSPI driver was not behaving as I would have
expected. While cheking out what was wrong I decided to clarify things
around so I did a bit of cleaning. The step-by-step changes are the
reason for patches [1-6]. This way, the last patch actually adding
support for both CS is much more understandable.

Thanks,
Miquèl

Changes since v1:
* Rebased on top of v5.4-rc6 and fixed all the conflicts
  (minors). Compile tested only (actual testing done on a v5.1).

Miquel Raynal (7):
  spi: zynq-qspi: Anything else than CS0 is not supported yet
  spi: zynq-qspi: Keep the naming consistent across the driver
  spi: zynq-qspi: Keep the bitfields naming consistent
  spi: zynq-qspi: Enhance the Linear CFG bit definitions
  spi: zynq-qspi: Clarify the select chip function
  spi: zynq-qspi: Do the actual hardware initialization later in the
    probe
  spi: zynq-qspi: Support two chip selects
