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 Naveen Kaje (2): i2c: qup: add ACPI support i2c: qup: support SMBus block read drivers/i2c/busses/i2c-qup.c | 122 ++++++++++++++++++++++++++++++++++++------- 1 file changed, 103 insertions(+), 19 deletions(-) -- Qualcomm Datacenter Technologies as an affiliate of Qualcomm Technologies, Inc.
