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:
	- Fix according to maintainer comments.
	- binding file changed to yaml format.
	- Shorten recovery flow.
	- Add support for health monitoring counters.

v9 -> v8:
	- Fix according to maintainer comments.
	- 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).

	  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"

v2 -> v1:
	- run check patch in strict mode.
	- use linux crc.
	- define regs in constant offset without base.
	- remove debug prints.
	- no declarations for local functions.
