Stephen (ping),

This patch together with the one sent today "[PATCH] clk: at91: fix 
at91sam9x5 peripheral clock number" make a good set for 5.0-final as 
they basically are real regressions.
This is true even if they apply on 4.20 as we were using an older biding 
definition until 5.0-rc...

Do what you can... As it's really late, I know...

Best regards,
   Nicolas
