[Freedreno] Whether A200 driver is supported by Linux Mainline Kernel

[abhijit]

Hi,

I needed some help with respect to binding of freedreno driver to mesa

I have cross compiled freedreno driver for A2XX with main line kernel 
and added clocking info referring driver from TQ-Embedded 
"https://www.tq-group.com/en/support/download 
/?tx_abdownloads_pi1%5Baction%5D=getviewcategory&tx_abdownloads_pi1%5Bcategory_uid%5D=672&tx_abdownloads_pi1%5Bcid%5D=84&tx_abdownloads_pi1%5Bpointer%5D=1&cHash=5e7c087ae16a9426fc0353db0042615a"

I also cross-compiled, libdrm and mesa components from freedreno git hub

But when I am running "glxinfo" command to verify whether underlaying 3D 
acceleration is being used, I am observing that softpipe is being used 
instead of "freedreno"

I figured it out that glxinfo uses mesa/src/mesa/drivers/dri/swrast  as 
user side driver component

Files under /src/mesa/drivers/dri use "_mesa_initialize_context" to 
register them self to mesa component. But I am not seeing any freedreno 
related source files calling "_mesa_initialize_context"

Can you please let me know whether I have to add mesa related 
functionalities for freedreno or there some other alternatives?

Thank you very much :)
