bus: mhi: Move host MHI code to "host" directory In preparation of the endpoint MHI support, let's move the host MHI code to its own "host" directory and adjust the toplevel MHI Kconfig & Makefile. While at it, let's also move the "pci_generic" driver to "host" directory as it is a host MHI controller driver.

bus: mhi: ep: Add support for registering MHI endpoint controllers This commit adds support for registering MHI endpoint controller drivers with the MHI endpoint stack. MHI endpoint controller drivers manage the interaction with the host machines (such as x86). They are also the MHI endpoint bus master in charge of managing the physical link between the host and endpoint device. Eventhough the MHI spec is bus agnostic, the current implementation is entirely based on PCIe bus. The endpoint controller driver encloses all information about the underlying physical bus like PCIe. The registration process involves parsing the channel configuration and allocating an MHI EP device. Channels used in the endpoint stack follows the perspective of the MHI host stack. i.e., UL - From host to endpoint DL - From endpoint to host Reviewed-by: Alex Elder <elder@linaro.org> Signed-off-by: Manivannan Sadhasivam <manivannan.sadhasivam@linaro.org> Link: https://lore.kernel.org/r/20220405135754.6622-2-manivannan.sadhasivam@linaro.org Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> 2022-04-05 19:27:37 +05:30
