2019-09-12staging: wilc1000: avoid twice IRQ handler execution for each single interruptAjay Singh1-1/+1
The IRQ handler(isr_bh_routine()) was called twice for each interrupt from firmware. The data was read completely during the first call and the second call was doing nothing. Now changed the IRQ flag from ‘level’ to ‘edge’ trigger i.e IRQF_TRIGGER_LOW to IRQF_TRIGGER_FALLING to avoid extra interrupt trigger.

2019-09-12staging: wilc1000: remove unused interrupt status handling codeAjay Singh2-34/+2
Remove interrupt handling for unused interrupt status(PLL update and Sleep). The firmware only initiates the interrupt for the data transfer to host and rest are not used anymore.

2019-04-16staging: remove redundant 'default n' from KconfigBartlomiej Zolnierkiewicz1-1/+0
'default n' is the default value for any bool or tristate Kconfig setting so there is no need to write it explicitly. Also since commit f467c5640c29 ("kconfig: only write '# CONFIG_FOO is not set' for visible symbols") the Kconfig behavior is the same regardless of 'default n' being present or not: ... One side effect of (and the main motivation for) this change is making the following two definitions behave exactly the same: config FOO bool config FOO bool default n With this change, neither of these will generate a '# CONFIG_FOO is not set' line (assuming FOO isn't selected/implied). That might make it clearer to people that a bare 'default n' is redundant. ...

2019-04-16staging: wilc1000: give usleep_range a rangeNicholas Mc Guire1-2/+2
usleep_range() is called in non-atomic context so there is little point in setting min==max as the jitter of hrtimer is determined by interruptions anyway. usleep_range can only perform the intended coalescence if some room for placing the hrtimer is provided. Given the range of milliseconds the delay will be 2+ anyway - so make it 2-2.5 ms which gives hrtimers space to optimize without negatively impacting performance.
