ChangeLog
v8:
- fix the name of the spi node in the DT example: from spi@f8034400 to
spi@2,0
- use the return code of op_property_read_u32_index() instead of -EINVAL
to report error.
- add Acked-by from Nicolas Ferre
v7:
- read the operating mode from the very first u32 of the reg property from
the first available child node (should be unique).
- update the DT bindings documentation accordingly.
v6:
- select the operating mode according to the "compatible" DT property of
the first available child node (should be unique).
- remove the "atmel,flexcom-mode" DT property so the need of a header file
defining macros for the possible values of this deprecated property.
v5:
- create a header file containing macros used by DT bindings
- use numeric constants instead of strings to select the Flexcom mode
- change the license to "GPL v2"
- update the DT binding documentation to make it more readable and add
references to USART, SPI and I2C DT binding documentations. remove the
useless label in the Example section.
- change the register prefix from FX_ to FLEX_ to match the Flexcom
programmer datasheet.
- rename some variables to make them more understandable.
v4:
- check clk_prepare_enable() return code in atmel_flexcom_probe()
- add a commit message to the DT binding patch
v3:
- remove MODULE_ALIAS()
- add Acked-by from Boris Brezillon and Alexandre Belloni
v2:
- enhance the documentation of DT bindings and change the way the "ranges"
property is used.
- replace __raw_readl() and __raw_writel() by readl() and writel().
- change the module license to "GPL" for v2 or later
- print the selected flexcom mode after the hardware version
v1:
This series of patches a support to the Atmel Flexcom, a wrapper which
integrates an USART, a SPI controller and a TWI controller. Only one
peripheral can be used at a time. The active function is selected though
the Flexcom Mode Register.
