Hi,
Changes in v2:
- fix error path in probe
- replace irq_of_parse_and_map with platform_get_irq
Changes in v1:
- free IRQ before irq_dispose_mapping
Jiada Wang (2):
ASoC: fsl_ssi: fix error path in probe
ASoC: fsl_ssi: use platform_get_irq instead
SSI component isn't unregistered if fsl_ssi_debugfs_create() fails
in probe phase.
To fix it, this commit replaces label error_asoc_register with
error_irq.

Use imx_start_tx() just to enable the TX interrupt. It's the job of the
TX interrupt ISR to fill the transmit buffer, then. If the transmit buffer
is empty, the TX interrupt should be executed as soon as the start_tx()
enables the interrupt, so there is no
a threshold.

Previously when channel0 timeouts to finish its task,
sdma_run_channel0() just returns without disable channel0,
this will cause continuous interrupt later when channel0
finishs its task and set channel0 interrupt bit.

what is the gaurantee that 1ms is fine? Shouldn't you

v3:
- updated commit message
- only check CLK_SET_RATE_GATE flag in case of 'PRE_RATE_CHANGE' event
- continue propagate rate change, even when there is error in
clk_propagate_rate_change()
v2:
- changed to return clk_core *core, instead of NULL

A better solution is so assume the jitter to be the nominal packetsize:
-one nearly empty packet followed by a almost double sized one.
