Manivannan Sadhasivam 6cd330ae76 bus: mhi: core: Add support for ringing channel/event ring doorbells ... This commit adds support for ringing channel and event ring doorbells by MHI host. The MHI host can use the channel and event ring doorbells for notifying the client device about processing transfer and event rings which it has queued using MMIO registers.
