Set gpio trigger before clearing the irq status. This patch was originally proposed by Grygorii Strashko. Cc: Grygorii Strashko <grygorii.strashko@xxxxxx> Reported-by: Markus Mirevik <markus.mirevik@xxxxxxxxxxxxxx> Closes: https://lore.kernel.org/all/20220122235959.GA10737@sol/T/ Signed-off-by: Markus Schneider-Pargmann <msp@xxxxxxxxxxxx> --- Hi everyone, this patch helped me on the beagleboneblack to remove the mentioned double trigger of level interrupts. This diff was proposed by Grygorii in the thread linked in the commit message. I am not sure why this never made it into the kernel, that's why I sending this patch. I did not create the diff just made a patch out of it, I don't care about being the author but I would be happy if this would get merged or some other solution to the problem. Thanks!
