* treewide: Make locally used functions staticSascha Hauer2019-03-181-1/+1
| | | | | | | Many functions are only used locally but still are globally visible. Make these function static. Avoids warnings generated with -Wmissing-prototypes Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* clocksource: mvebu: don't request the used iomem resourceUwe Kleine-König2017-03-311-1/+1
| | | | | | | | | | | The register ranges of the device nodes timer@20300 and watchdog@20300 overlap, so it is impossible that both devices properly use request_iomem_region (e.g. by using dev_request_mem_resource). In Linux only the watchdog driver is registered in /proc/iomem, do the same for barebox.

* driver: replace dev_request_mem_region with dev_request_mem_resourceSascha Hauer2016-03-071-3/+5

Replace them with dev_request_mem_resource where possible.

* clocksource: mvebu: split initialization for Armada 370/XPSebastian Hesselbarth2014-06-241-25/+40
| | | | | | | | | | | Timers found on Marvell Armada 370 and XP require different setup. While timer clock on Armada 370 can be derived from a divided reference clocks, Armada XP always uses a 25MHz reference. This also updates compatibles to destinguish timers for both SoCs and fixes some whitespace issues on defines. Signed-off-by: Sebastian Hesselbarth <sebastian.hesselbarth@gmail.com>
* clocksource: mvebu: add DT supportSebastian Hesselbarth2013-07-051-0/+6
| | | | | | | | This adds device tree support to mvebu timer and also converts clk_get to clk_lookup to find TCLK without device name reference. Signed-off-by: Sebastian Hesselbarth <sebastian.hesselbarth@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* clocksource: mvebu: lookup clock by physbaseSebastian Hesselbarth2013-07-051-2/+1
| | | | | | | | This converts Armada 370/XP SoC init to register tclk alias for timer by physbase instead of name. Signed-off-by: Sebastian Hesselbarth <sebastian.hesselbarth@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* clocksource: fix Marvell timer read-back valueSebastian Hesselbarth2013-06-291-1/+1
| | | | | | | | | Clocksource read callback expects incrementing timer values, while internal timer on Marvell SoCs counts backwards.
