* resource: Let dev_request_mem_region return an error pointerSascha Hauer2014-09-161-0/+3
| | | | | | For all users fix or add the error check. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* watchdog: add minimal jz4740 driverAntony Pavlov2014-08-013-0/+110
| | | | | | | | | | | | Also move reset_cpu() for jz4755 SoC from platform code into the new driver code. At the moment mach-xburst lacks clk support so jz4740 watchdog driver looks like a template. We can improve jz4740 watchdog driver later after adding clk support. Signed-off-by: Antony Pavlov <antonynpavlov@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* reset_source: rename set_reset_source to reset_source_setSascha Hauer2014-01-292-7/+7
| | | | | | | To get all reset source related functions into the same function namespace. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* treewide: Add missing includesSascha Hauer2013-11-081-0/+1
| | | | | | | | A lot of files rely on include/driver.h including include/of.h (and this including include/errno.h. include the files explicitly so we can eventually get rid of including of.h from driver.h Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* ARM/MXS: add more ROM code related documentationJuergen Beisert2013-04-091-1/+74
| | | | | | | | | | | Commit 17176c2e2bba606190d9ae51943acb5701063573 adds a test of a new RTC register flag to distinguish a system reset and a wake up event. Shame on me, I have forgotten to define the newly used flag yet. While already here, I also try to document the other flags the RTC provides.

| | | | | | | | | | | | | | | | | | This patch provides a global cleanup barebox Kconfig files. This includes replacing spaces to tabs, formatting in accordance format, removing extraneous lines and spaces. No functional changes.

* | ARM/MXS/i.MX28: distinguish POR and wake-up event correctlyJuergen Beisert2012-12-031-0/+11
|/ | | | | | | | | | | When the built-in RTC in the i.MX28 is programmed to wake-up the SoC, the RTC reports two events: RST and WAKE. RST is okay in this case, because the PMIC was really powered down. But the real event is the WAKE from the RTC and should have precedence over the RST event. So, report the WAKE event for this special case. Signed-off-by: Juergen Beisert <jbe@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* ARM i.MX: move reset source detection codeSascha Hauer2012-10-081-0/+34
| | | | | | | | | - for i.MX1 the register is in the System Control unit, so move the code to arch/arm/mach-imx/imx1.c - for the other i.MX the register is in the watchdog unit, so move the code to drivers/watchdog/imxwd.c Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
