I see FREESCALE QUICC ENGINE LIBRARY (drivers/soc/fsl/qe/) is maintained
by Qiang Zhao <qiang.zhao@xxxxxxx> but I can't find any mail from him in
the past 4 years in linuxppc-dev list, and everytime I wanted to submit
something I only got responses from Leo Ly.
The last commit he reviewed is 661ea25e5319 ("soc: fsl: qe: Replace
one-element array and use struct_size() helper"), it was in May 2020.
Is he still working at NXP and actively maintaining that library ?
Keeping this part maintained is vital for me as this SOC is embedded in
the two powerpc platform I maintain (8xx and 83xx).
If Qiang Zhao is not able to activaly maintain that SOC anymore, I
volonteer to maintain it.
Thanks
Christophe
