Hi These patches are for linux-omap but we want to wide discussion also to linux-i2c is the new command line option "i2c_bus=bus_id,clkrate" generic enough to be used for other architectures as well in the future. Patches are generated on top of mainline 2.6.29-rc7.
Purpose of this command line option is to both allow to override the default board specific bus speed (patch 2) and register additional busses that are not registered from board initialization code (patch 3). Example for patch 2 would be the case where some on board component is upgraded and which allows to use e.g. higher clock rate on the bus without other major board changes. Patch 3 can have more practical use however. E.g. second I2C bus on TI BeagleBoard doesn't have on board components and thus it is not registered by default with omap_register_i2c_bus. This bus is routed to expansion pin header so with this patch it is able to register dynamically when needed. These patches are previously discussed in these threads: http://marc.info/?l=linux-omap&m=123635604511892&w=2 http://marc.info/?l=linux-omap&m=123661915517228&w=2 -- Jarkko -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
