Diff from v3:
- Fix over 80chars in one place
- Move check for adapter being able to dynamically update TAR to be done
on probe time rather than init as requested by Jarkko
For the previous version, Christian had added:
Tested-by: Christian Ruppert <christian.ruppert@alitech.com>
on TB101 with Linux-4.7
And Jarkko added his Acked-by: Jarkko Nikula <jarkko.nikula@linux.intel.com>
on patches 1 and 3 (now 4).
There's a new patch #2 as a preparatory work to move the check
mentioned above to i2c_dw_probe().
v3 of "i2c: designware: do not disable adapter after transfer". Differences
are:
- Now there's a first patch that does not depend on IC_TAR being dynamically
enabled/disabled: it just doesn't wait for the state change when not needed.
- We added a patch that allows detecting if HW supports the dynamic TAR updates
- In the last patch the bits were changed as suggested by Jarkko.
- This is tested on BayTrail and CherryTrail, both of them returning true for
"dynamically update TAR"
José Roberto de Souza (1):
i2c: designware: wait for disable/enable only if necessary
Lucas De Marchi (3):
i2c: designware: add common functions for locking
i2c: designware: detect when dynamic tar update is possible
i2c: designware: do not disable adapter after transfer
