Hello!
This series performs a small refactoring of the Tegra I2C driver code and
hardens the atomic-transfer mode.
Changelog:
v3: - Optimized "Make tegra_i2c_flush_fifos() usable in atomic transfer"
patch by pre-checking FIFO state before starting to poll using
ktime API, which may be expensive under some circumstances.
- The "Clean up messages in the code" patch now makes all messages
to use proper capitalization of abbreviations. Thanks to Andy Shevchenko
and Michał Mirosław for the suggestion.
- The "Remove unnecessary whitespaces and newlines" patch is transformed
into "Clean up whitespaces and newlines", it now also adds missing
newlines and spaces.
- Reworked the "Clean up probe function" patch in accordance to
suggestion from Michał Mirosław by factoring out only parts of
the code that make error unwinding cleaner.
- Added r-b from Michał Mirosław.
- Added more patches:
i2c: tegra: Reorder location of functions in the code
i2c: tegra: Factor out packet header setup from tegra_i2c_xfer_msg()
i2c: tegra: Remove "dma" variable
i2c: tegra: Initialization div-clk rate unconditionally
i2c: tegra: Remove i2c_dev.clk_divisor_non_hs_mode member
v2: - Cleaned more messages in the "Clean up messages in the code" patch.
- The error code of reset_control_reset() is checked now.
- Added these new patches to clean up couple more things:
i2c: tegra: Check errors for both positive and negative values
i2c: tegra: Improve coding style of tegra_i2c_wait_for_config_load()
i2c: tegra: Remove unnecessary whitespaces and newlines
i2c: tegra: Rename variable in tegra_i2c_issue_bus_clear()
i2c: tegra: Improve driver module description
