Subject: [PATCH 01/20] bus: mhi: Move host MHI code to "host" directory
Date: Thu, 2 Dec 2021 17:05:33 +0530 [thread overview]
Message-ID: <20211202113553.238011-2-manivannan.sadhasivam@linaro.org> (raw)
In-Reply-To: <20211202113553.238011-1-manivannan.sadhasivam@linaro.org>
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.
