Modularizing drivers, which can work as modules or even can be disabled
because they are not essential for platform boot, is not opening
loophole and is helping upstream platforms. Modularizing everything,
even essential drivers, because downstream does not want to contribute
rest of its drivers, is not beneficial to the upstream project. Since
downstream does want to contribute its platforms and drivers, it decides
to change mainline project to fits its needs. Only its needs, not others.
I was repeating this multiple times - there is no point, no incentive
for the mainline to allow disabling essential SoC drivers. It's only
downstream interest without any benefit to the upstream.
Best regards,
Krzysztof
