Subject: [PATCH v7 0/3] spi: support for Socionext Synquacer platform
Date: Tue, 4 Jun 2019 14:12:54 +0900 [thread overview]
Message-ID: <20190604051257.14264-1-masahisa.kojima@linaro.org> (raw)
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 v6:
# Removed dependency to SPI_BITBANG
# Added -EPROBE_DEFER handling for devm_clk_get()
# Added check of invalid index(0) of platform_get_irq()
# Set the fwnode member
# Removed redundant error check for sspi->clk
Changes since v5:
# Supported ACPI probing and added ACPI device table(SCX0004)
# Removed DT dependencies
# Removed to call _relaxed variants to access the registers
# Updated irq name to use dev_name()
# Updated return value for irq handlers
# Explicitly listed the supported bits_per_word
# Removed FIFO handling from a set_cs() operation
Changes since v4:
# Supported interrupt based data handling instead of polling
# Added prefix "SYNQUACER_HSSPI_"
# Replaced data read/write access with readsx()/writesx()
# Updated clock source handling, explicitly specify "iHCLK" or "iPCKL"
and removed array of clk
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.
