6.11-stable review patch. If anyone has any objections, please let me know.

[ Upstream commit b03ffc76b83c1a7d058454efbcf1bf0e345ef1c2 ]
For UART devices the M_GP_LENGTH is the TX word count. For other devices this is the transaction word count.
For UART devices the S_GP_LENGTH is the RX word count.
The IRQ_EN set/clear registers allow you to set or clear bits in the IRQ_EN register without needing a read-modify-write.
