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). - 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"
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. v1: initial version
