[U-Boot] [PATCH v5 00/16] device model bring-up of ti-qspi on dra72, dra74 and am437x-sk evm

[Mugunthan V N]

This patch series enables ti_qspi to adopt driver model. This has
been tested on dra72, dra74 and am437x-sk evms (logs [1]).
Also pushed a branch for testing [2]

This patch series is based on u-boot-spi/next and a fix for
Macronix flash Quad Enable as per the comments in thread [3].

Changes from v4->v5
* Adopt to latest spi framework changes by Jagan [3] and [4]

Changes from v3->v4:
* used op_mode_{t/r}x to hold flash tx/rx modes.

Changes from v2->v3:
* removed usage of spi_slave structure in driver model and introduced
  required variables in qspi priv itself.
* Used fdt_addr_cells() and fdt_size_cells() instead of hard-coding
  size of each address-size pair.
* Changed qspi dts entries to be same as in kernel qspi dts patch for
  avoiding future conflicts.
* Fixed some typos and added more info in commits.
* Added error check on chip select passed from framework.
* Removed un-used define QSPI_RD_DUAL.

Changes from Initial version:
* Split "prepare driver for DM conversion" for easier review
* added memory map mode to the driver
* Fixed the cosmetic reviews from Simon
* Modified the dev_get_addr_index to adopt OF_TRANSULATE as well
  and also removed code duplicate.
* Added compatibles for spi flashed found in DRA7xx and AM437x SK
