Resending the patches as I have missed 01/17 patch while sending v6 series
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 v5->v6: * Removed adding flash compatibles to flash driver and added "spi-flash" compatible to dts as done by other flash devices.
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
