slimbus: ngd: remove unnecessary check

2018-11-07T13:59:28+00:00

SLIM_MSG_CLK_PAUSE_SEQ_FLG is never set in any of the slim core, so performing a check in ngd driver is totally unnecessary. Also this patch fixes warning about mc field overflow reported with CoverityScan. Making clk pause feature optional will be added to slim core in next development cycle.

slimbus: core: update device status in probe

2018-09-25T18:21:02+00:00

device status update can be racy with probe in some cases, so make sure it take lock during the probe. Also after probe the device is expected to be ready for communications, so make sure that a logical address can be assigned to it after probe. If it fails to do so then probe defer such instances.

slimbus: core: match device tree based devices correctly

2018-09-25T18:21:02+00:00

device_id for device tree based devices come from dt compatible string, such drivers need not provide non dt style device id table. Match those device using compatible strings. Signed-off-by: Srinivas Kandagatla Signed-off-by: Greg Kroah-Hartman

silmbus: ngd: register controller after power up.

2018-09-25T18:21:02+00:00

Register slimbus controller only after finishing powerup sequnce so that we do not endup in situation where core starts sending transactions before the controller is ready. Signed-off-by: Srinivas Kandagatla Signed-off-by: Greg Kroah-Hartman

slimbus: ngd: mark PM functions as __maybe_unused

2018-09-14T13:36:20+00:00

qcom_slim_ngd_runtime_suspend is protected by an #ifdef, qcom_slim_ngd_runtime_idle is now, which causes a build time warning: drivers/slimbus/qcom-ngd-ctrl.c:1470:12: error: 'qcom_slim_ngd_runtime_idle' defined but not used [-Werror=unused-function] Marking both as __maybe_unused lets us get rid of the warning as well as the #ifdef.
