Subject: [PATCH v6 0/2] Add ACPI support and SMBus block read
Date: Tue, 11 Oct 2016 10:27:55 -0600 [thread overview]
Message-ID: <1476203277-6893-1-git-send-email-austinwc@codeaurora.org> (raw)
From: Austin Christ <austinwc@qti.qualcomm.com>
Add ACPI support to I2C QUP driver and get properties from ACPI table.
Add support to the I2C QUP driver to correctly handle SMBus block reads by
checking I2C_M_RECV_LEN flag and reading the first byte received as the
message length.
Documentation for the two properites used from ACPI has been submitted through
dsd@acpica.org to https://github.com/ahs3/dsd. The documentation can be viewed
at https://lists.acpica.org/pipermail/dsd/2016-September/000095.html.
[V6]
- correct block size for SMBus data read
[V5]
- remove warning and use correct ACPI function
[V4]
- correct error code
- remove warning for fall back to default clock frequency
[V3]
- clean up unused variables
- use constant instead of variable for smbus length field
[V2]
- rework the smbus block read and break into separate function
- clean up redundant checks and variables
