Subject[PATCH v5 00/10] i2c: npcm: Bug fixes timeout, spurious interrupts
Date
From: Tyrone Ting <kfting@nuvoton.com>

This patchset includes the following fixes:

- Add dt-bindings description for NPCM845.
- Bug fix for timeout calculation.
- Better handling of spurious interrupts.
- Fix for event type in slave mode.
- Removal of own slave addresses [2:10].
- Support for next gen BMC (NPCM845).

The NPCM I2C driver is tested on NPCM750 and NPCM845 evaluation boards.

addresses 2:10. Correct the if statement in one line and shorten the
debug messages.
- Create a new patch to capitalize the one-line comment in the driver.

Changes since version 3:
- Correct the const format in if condition in i2c binding document.
- Add the oops message statement and register information in register
access width patch.
- Add the occurring rate of the i2c spurious interrupt issue and more
details in driver's behavior to overcome this issue.
- Address Andy's comments in the patch to support NPCM845.

Changes since version 2:
- Keep old code as fallback, if getting nuvoton,sys-mgr property fails.
- Fix the error reported by running 'make DT_CHECKER_FLAGS=-m
dt_binding_check'.
- Make nuvoton,sys-mgr required for nuvoton,npcm845-i2c.
- Correct the patch's subject about changing the way of getting GCR
regmap and add the description about keeping old code as fallback
if getting nuvoton,sys-mgr property fails.
- Correct the patch title and description about removing the unused
variable clk_regmap.
- Use the data field directly instead of the macros since macros are
not constants anymore in this patch.

Changes since version 1:
- Add nuvoton,sys-mgr property in NPCM devicetree.
- Describe the commit message in imperative mood.
- Modify the description in i2c binding document to cover NPCM series.
- Add new property in i2c binding document.

- Remove some comment since the corresponding logic no longer exists.
- Remove fixes tag while the patch adds an additional feature.
- Use devicetree data field to support NPCM845.
