Somehow I remember that enabling things by default is not looked kindly at. Shouldn't they be enabled in the arch/arm/configs config file, if they are wanted? Tony, do you have opinnion on this? Should DSS features be enabled by default in the Kconfig files, or only in the board config file? Also, see one comment inline. > Warm Regards, > Samreen > Nilofer, Samreen wrote: > > The defconfig options for display are taken in the respective > > Kconfig to enable display by default on OMAP3 platforms > > > > Signed-off-by: Samreen <samreen@xxxxxx> > > --- > > Version4: > > Remove the enabling of the display panels by default. > > > > Version3: > > Eliminate the separate default number of FBs for > > different architecture.
