[PATCHv4 0/3] spi: support for Socionext Synquacer platform

[jassisinghbrar@xxxxxxxxx]

From: Jassi Brar <jaswinder.singh@xxxxxxxxxx>

Hello,

 Support for Socionext's FIP controller intended for flash device interfacing.
The controller can operate in 'direct' or 'command' mode. One mode directly
talks and provide a read/write i/f to the flash device. Other works as plain
SPI mode. This driver runs the controller as a SPI controller.

Changes since v3:
	# Convert IS_ERR returned from devm_clk_get(iPCLK) to NULL, that way
	  we can call clk_xxx(IPCLK) without first checking for it being valid.

Changes since v2:
        # Made iHCLK clock property required in DT, and iPCLK an optional extra.
        # Hardcode max number of slaves to 4, as specified in the manual.

Changes since v1:
        # Changed licence header to C++ style comment.
        # Removed redundant lock and transfer_mode backup member.
        # Fixed divisor to allow upto 254.
