clocksource: tcb_clksrc: sanitize IRQ request

2014-09-08T08:54:03+00:00

The clock is not unprepared in case of the request IRQ fails.

Also update to request_irq.

ARM: at91/tclib: move initialization from alloc to probe

2014-09-08T08:54:03+00:00

Move resource retrieval from atmel_tc_alloc to tc_probe to avoid lately
reporting resource related issues when a TC block user request a TC block.

Moreover, resources retrieval are usually done in the probe function,
thus moving them add some consistency with other drivers.

Initialization is done once, ie not every time a tc block is requested.
If it fails, the device is not appended to the list of tc blocks.

Furhermore, the device id is retrieved at probe as well, avoiding parsing
DT every time the user requests of tc block.

clocksource: tcb_clksrc: Make tc_mode interrupt safe

2014-05-22T16:54:58+00:00

tc_mode() can be called from interrupt context and thus must not call
clk_*prepare*() functions.

clocksource: use clockevents_config_and_register() where possible

2013-01-14T18:12:42+00:00

The clockevent core is able to figure out the best mult and shift,
calculate min_delta_ns and max_delta_ns, with the necessary info passed
into clockevents_config_and_register().  Use this combined configure
and register function where possible to make the codes less error prone
and gain some positive diff stat.

ARM: at91/tc/clocksource: Add 32 bit variant to Timer Counter

2012-03-01T12:38:49+00:00

Some SoC have a 32 bit variant of Timer Counter Blocks. We do not
need the chaining of two 16 bit counters anymore for them.

The SoC nature is deduced from the device tree "compatible" string.
For non-device-tree configurations, backward compatibility is maintained
by using the default 16 bit counter configuration.

This patch addresses both the atmel_tclib and its user: tcb_clksrc
clocksource.

drivers/clocksource/tcb_clksrc.c: fix init sequence

2011-01-26T00:50:04+00:00

setup_irq() was called before clockevents_register_device() which is
needed by the irq handler.  Bug was reproducible by restarting the
kernel using kexec (reliable crash).
