HSI: omap_ssi: call msg->complete() from process context

2016-06-27T22:40:00Z

msg->complete() should always be called from process context once irq_safe runtime pm flag is no longer set for omap-ssi. Signed-off-by: Sebastian Reichel Tested-by: Pavel Machek

HSI: omap_ssi_port: switch to threaded pio irq

2016-06-27T22:39:32Z

Move pio interrupt handler from tasklet into thread to allow runtime_pm_get_sync calls without irq_safe being set. Signed-off-by: Sebastian Reichel Tested-by: Pavel Machek

HSI: omap_ssi_port: prepare start_tx/stop_tx for blocking pm_runtime calls

2016-06-27T22:39:15Z

ssi_start_tx and ssi_stop_tx may be called from atomic context. Once pm_runtime_irq_safe() is removed for omap-ssi, this will fail, due to blocking pm_runtime_*_sync() calls. This fixes ssi_stop_tx by using non-sync API and ssi_start_tx by using a worker thread. Signed-off-by: Sebastian Reichel Tested-by: Pavel Machek

HSI: omap_ssi_port: replace wkin_cken with atomic bitmap operations

2016-06-27T22:38:47Z

This simplifies the code and avoids holding a spin_lock when runtime pm calls are made. Once the irq_safe flag is removed for omap_ssi's runtime pm, pm_runtime_get/put_sync can sleep, which is a no-go while holding a spin_lock. Signed-off-by: Sebastian Reichel Tested-by: Pavel Machek

HSI: omap_ssi: convert cawake irq handler to thread

2016-06-27T22:38:43Z

Convert cawake interrupt handler from tasklet to threaded interrupt handler in preparation of blocking runtime_pm calls. Signed-off-by: Sebastian Reichel Tested-by: Pavel Machek

HSI: omap_ssi: do not reset module

2016-06-27T22:37:43Z

module reset and power management rule setup is already done by hwmod. Remove this cruft, which predates hwmod. Signed-off-by: Sebastian Reichel Acked-by: Tony Lindgren Tested-by: Pavel Machek

HSI: omap-ssi: add clk change support

2016-05-02T19:56:25Z

This adds support for frequency changes of the SSI functional clock, which may occur due to DVFS. Acked-by: Pavel Machek Signed-off-By: Sebastian Reichel

HSI: omap_ssi: built omap_ssi and omap_ssi_port into one module

2016-05-02T19:56:21Z

Merge omap_ssi and omap_ssi_port into one module. This fixes problems with module cycle dependencies introduced by future patches. Acked-by: Pavel Machek Signed-off-by: Sebastian Reichel

HSI: omap_ssi_port: switch to gpiod API
