clocksource/drivers/mips-gic-timer: Make gic_compare_irqaction static

2019-03-22T21:59:33Z

Fix sparse warning: drivers/clocksource/mips-gic-timer.c:70:18: warning: symbol 'gic_compare_irqaction' was not declared. Should it be static? Signed-off-by: YueHaibing Signed-off-by: Thomas Gleixner Cc: Link: https://lkml.kernel.org/r/20190322144359.19516-1-yuehaibing@huawei.com

clocksource/drivers/mips-gic-timer: Add pr_fmt and reword pr_* messages

2018-05-18T20:53:09Z

Several messages from the MIPS GIC driver include the text "GIC", "GIC timer", etc, but the format is not standard. Add a pr_fmt of "mips-gic-timer: " and reword the messages now that they will be prefixed with the driver name. Signed-off-by: Matt Redfearn Signed-off-by: Daniel Lezcano

clocksource/drivers/mips-gic-timer: Use correct shift count to extract data

2018-02-28T12:55:14Z

__gic_clocksource_init() extracts the GIC_CONFIG_COUNTBITS field from read_gic_config() by right shifting the register value. The shift count is determined by the most significant bit (__fls) of the bitmask which is wrong as it shifts out the complete bitfield. Use the least significant bit (__ffs) instead to shift the bitfield down to bit 0.

treewide/trivial: Remove ';;$' typo noise

clocksource/drivers/mips-gic-timer: Add fastpath for local timer updates

2017-10-19T21:51:31Z

Always accessing the compare register via the CM redirect region is (relatively) slow. If the timer being updated is the current CPUs then this can be shortcutted by writing to the CM VP local region. Signed-off-by: Matt Redfearn Signed-off-by: Daniel Lezcano

clocksource/drivers/mips-gic-timer: Remove pointless irq_save,restore

2017-10-19T21:49:45Z

The function gic_next_event is always called with interrupts disabled, so the local_irq_save / local_irq_restore are pointless - remove them.

clocksource: mips-gic-timer: Use new GIC accessor functions

2017-08-30T12:30:07Z

Switch from calling functions exported by the GIC interrupt controller to using new accessors provided by asm/mips-gic.h. This will allow the counter-handling functionality to be removed from the interrupt controller driver, where it doesn't really belong, and also allow for inlining of the accesses to the GIC.

clocksource/drivers/mips-gic-timer: Fix an error code in 'gic_clocksource_of_init()'

2017-06-27T09:25:40Z

'clk' is a valid pointer at this point. So calling PTR_ERR on it is pointess. Return the error code from 'clk_prepare_enable()' if it fails instead. Signed-off-by: Christophe JAILLET Signed-off-by: Daniel Lezcano

clocksource/drivers: Rename CLOCKSOURCE_OF_DECLARE to TIMER_OF_DECLARE

2017-06-14T09:58:45Z

The CLOCKSOURCE_OF_DECLARE macro is used widely for the timers to declare the clocksource at early stage. However, this macro is also used to initialize the clockevent if any, or the clockevent only. It was originally suggested to declare another macro to initialize a clockevent, so in order to separate the two entities even they belong to the same IP. This was not accepted because of the impact on the DT where splitting a clocksource/clockevent definition does not make sense as it is a Linux concept not a hardware description. On the other side, the clocksource has not interrupt declared while the clockevent has, so it is easy from the driver to know if the description is for a clockevent or a clocksource, IOW it could be implemented at the driver level. So instead of dealing with a named clocksource macro, let's use a more generic one: TIMER_OF_DECLARE. The patch has not functional changes.

Clocksource/mips-gic: Remove redundant non devicetree init

2017-04-20T12:56:59Z

Malta was the only platform probing this driver from platform code without using device tree. With that code removed, gic_clocksource_init is redundant so remove it.
