Subject: [PATCH v14 0/3] i2c: npcm7xx: add NPCM i2c controller driver
This patch set adds i2c controller support
for the Nuvoton NPCM Baseboard Management Controller (BMC).
NPCM7xx includes 16 I2C controllers. This driver operates the controller.
This module also includes a slave mode.
---
v14 -> v13:
- Fix yaml example: add missing include.
- Replace all udelay to usleep_range, except one which is called from
irq.
- Fix compilation error (module_platfrom_init conflict).
- debugfs counters always updated. Counting till max value,
then stop counting.
- Rename bus-frequency to clock-frequency.
- Remove unused variables.
v13 -> v12:
- Fix yaml example. Issue found by an updated dt_binding_check.
- remove double spacing. indentation issues.
- remove ifdef DEBUG_FS around __init and __exit.
- debugfs and counters are always present in bus struct.
- Fix npcm_i2c_write_fifo_slave flow.
- Remove version number.
v12 -> v11:
- Fix according to maintainer comments.
- debugfs simplified (usedebugfs_create_u64).
- slave read fifo split from master read fifo.
v11 -> v10:
- Fix according to maintainer comments.
- Init clk simplified.
- Comments in c99
- Split master irq function.
- debugfs not mandatory.
- yaml file fix.
v10 -> v9:

- Split lines of iowrite..(ioread..) to separate lines.
- Use readx_poll_timeout_atomic
- resolve various style issues.
v8 -> v7:
- Split to two commits, one for master, one for slave.
- Rename smb to i2c.
- Remove global vars.
v7 -> v6:
- Rebased on Linux 5.4-rc8 (was Linux 5.4-rc7).
- Fix issue found by kbuild test robot (redundant include).
- Note: left a warning related to fall through. This fall through is
intentional.
v6 -> v5:
- Update documentation
v5 -> v4:
- support recovery
- master-slave switch support needed for IPMB
v4 -> v3:
- typo on cover letter.
v3 -> v2:
- fix dt binding: compatible name: omit "bus"
