Subject: [PATCH v1 0/6] BHI/BHIe improvements for MHI power purposes
Date: Fri, 16 Apr 2021 11:46:59 -0700 [thread overview]
Message-ID: <1618598825-18629-1-git-send-email-bbhatt@codeaurora.org> (raw)
This patch series improves the power up behavior by allowing MHI host driver to
set BHI and/or BHIe offsets early on in the preparation phase and fail pre-power
up if offsets are not found or not within a limited MMIO region. This also
allows MHI host to clean up the offsets in the unprepare after power down phase.
Going forward, controllers will be required to specify a reg_len field which
will be used to check whether the BHI/BHIe offsets are in range or not.
This series has been tested on X86_64 architecture with the PCI generic driver
as controller and an SDX55 device.
Bhaumik Bhatt (6):
bus: mhi: core: Set BHI/BHIe offsets on power up preparation
bus: mhi: core: Set BHI and BHIe pointers to NULL in clean-up
bus: mhi: Add MMIO region length to controller structure
ath11k: set register access length for MHI driver
bus: mhi: pci_generic: Set register access length for MHI driver
bus: mhi: core: Add range checks for BHI and BHIe
