Hi There are two public discussions now related to OMAP boot and drivers initialization issues: "Multiple issues with omap4 panda es in linux next" http://www.spinics.net/lists/linux-omap/msg90241.html "[BUG] omap: mfd/regulator: twl/core: init order" http://www.spinics.net/lists/linux-omap/msg89980.html In both cases there are pinctrl-single/I2C/MFD/Regulators initailization issue: - regulators are not initialized because of twl, - twl is not initialized because of I2C, - I2C is not initialized because of pinctrl-single, - pinctrl-single is initialized at mudule/device init time. So, most everything will be shifted at late_initcall time. This may cause boot delay (more over, it can broken initialization of drivers which are not ready to use deferred probe mechanism yet, for example DSS). Introduced pathes shift I2C and TWL iniialization to module/device init layer instead of subsys init layer where initialization dependencies resolved indirectly in drivers/Makefile now.
