* i.MX: Move clk code from 'mach-imx' to 'drivers'Andrey Smirnov2017-01-111-196/+0
| | | | | | | | | Move clk code from 'mach-imx' to 'drivers' to keep the code tree structure closer to that of analogous one from Linux kernel and, arguably although subjective, to keep 'mach-imx' less cluttered.

* 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.

* video: imx: Add a name to perclkSascha Hauer2014-02-101-1/+1
| | | | | | perclk should be named 'per' to make sure we get the correct clock. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* ARM: i.MX: Make timer available earlierSascha Hauer2013-06-181-1/+1
| | | | | | | | This moves the CCM drivers to core_initcall since this has no dependencies. This way we can be sure that the clock for the clocksource is available in at postcore_initcall time. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* i.MX21/27: don't enable lcd bus clocks too earlyDaniel Mierswa2013-01-171-2/+11
| | | | | | | | | | | | | | | | On the MX27 based board phycard-i.MX27 the display won't properly come up. Before removing imx-regs.h and the code that sets the register in the i.MX video driver, the PCCR registers were set _after_ the screen start (LSSAR) was set. This restores that old behaviour and makes the display come up properly again. I did not have a chance to test this on any other i.MX27 or i.MX21 hardware though I assume that the "old" order is required there too.
