10:46 <narmstrong> The_Coolest: hi, not much overhead but gpio bitbanging will never be efficient using the gpio framework

10:47 <narmstrong> The_Coolest: by the way, why don’t you use the kernel gpio bitbanging helpers to i2c and spi ???

10:47 <narmstrong> and why bitbanging ? The aml SoCs have plenty of i2c interfaces

14:49 <The_Coolest> narmstrong>> Hmm. I think I looked at those helpers, they won't do what I need because they use DTB definitions.

14:50 <The_Coolest> And bitbanging because most of the hardware the code will be running on won't have the display connected to a SPI\I2C port

16:18 <narmstrong> The_Coolest: question, is this for mainline Linux ? 5 lines of DT vs 500k lines of possible buggy custom code ? These helpers has been written to avoid needing to rewrite them again and are bug-free ;-)

17:40 <The_Coolest> Can't do it in DT because the whole point of my driver is to be easily configurable, rather than having to maintain a bunch of DTBs.

17:40 <The_Coolest> that came out wrong.

17:41 <The_Coolest> The point is for the driver to work on any Amlogic S905\S912 tv box/SBC. Be easy to configure, and not require maintaining a bunch of DTBs - as we already tried that bit.

17:44 <The_Coolest> We're also looking at possibly adding support for other platforms too.

17:44 <The_Coolest> Currently we're building against 3.14 kernel
