Note that after dropping these lines:

       CLKDEV_DEV_ID("fcfee000.i2c", &mstp_clks[MSTP97]),
       CLKDEV_DEV_ID("fcfee400.i2c", &mstp_clks[MSTP96]),
       CLKDEV_DEV_ID("fcfee800.i2c", &mstp_clks[MSTP95]),
       CLKDEV_DEV_ID("fcfeec00.i2c", &mstp_clks[MSTP94]),

i2c stopped working.

Before:

of_irq_parse_one: dev=/i2c@fcfee800/eeprom@50, index=0
at24 2-0050: 16384 byte 24c128 EEPROM, writable, 64 bytes/write
i2c-riic fcfee800.i2c: registered with 400000Hz bus speed

After:

i2c-riic fcfee800.i2c: missing controller clock
i2c-riic: probe of fcfee800.i2c failed with error -2

Am I missing some other patch?

Gr{oetje,eeting}s,

                        Geert

when I'm talking to journalists I just say "programmer" or something like that.
