* clk: mxs: remove the use of mach level IO accessorShawn Guo2013-04-01
| | | | | | | | It removes the use of mach level IO accessor __mxs_setl/clrl, and hence removes mach header inclusion from clock driver. Signed-off-by: Shawn Guo <shawn.guo@linaro.org> Acked-by: Mike Turquette <mturquette@linaro.org>
* clk: mxs: get base address from device treeShawn Guo2013-04-01
| | | | | | | | | | | Instead of using the static definitions, get clkctrl and digctl base addresses with mapping from device tree. Use macro on variable is not nice, but it's done here to save huge pointless diff stat. Signed-off-by: Shawn Guo <shawn.guo@linaro.org> Acked-by: Mike Turquette <mturquette@linaro.org>
* ARM: mxs: look up timrot clock from device treeShawn Guo2013-04-01
| | | | | | | | Change call clk_get_sys() to of_clk_get() to look up timrot clock from device tree, so that the clk_register_clkdev() call for timrot can be saved in clock driver. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
* ARM: mxs: use CLKSRC_OF helper to initialize timerShawn Guo2013-04-01
| | | | | | | Select CLKSRC_OF and use clocksource_of_init() to initialize timer, so that the call to mxs_timer_init() in clock driver can be removed. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>

| * ARM: mxs: retrieve timer irq from device treeShawn Guo2012-09-02
| | | | | | | | | | | | | | Rather than using the static timer irq definition, we should retrieve timer irq from device tree for better. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
* | clk: mxs: replace imx23 clk_register_clkdev with clock DT lookupShawn Guo2012-09-11
|/ | | | | | | | | | | | | It really becomes a maintenance issue that every time a device needs to look up (clk_get) a clock we have to patch kernel clock file to call clk_register_clkdev for that clock. Since clock DT support which is meant to resolve clock lookup in device tree is in place, the patch moves imx23 client devices' clock lookup over to device tree, so that any new lookup to be added at later time can just get done in DT instead of kernel.

* | clk: mxs: fix clock lookup after freeing init memoryMarc Kleine-Budde2012-06-25
|/ | | | | | | | | | | | The struct clk_lookup are marked as __initdata, resulting in being removed from memory after the kernel finished booting. However this leads to a NULL pointer de-ref if loading a module which uses clk_get. This patch removes the __initdata from the struct clk_lookup.

* mmc: mxs-mmc: get rid of the use of cpu_is_xxxShawn Guo2012-05-12
| | | | | | | | | | The register HW_SSP_VERSION is broken for ssp version detection, as the address of the register is different between imx23 and imx28. Let's use platform_device_id to detect the device, so that the use of cpu_is_xxx can be removed. Signed-off-by: Shawn Guo <shawn.guo@linaro.org> Acked-by: Chris Ball <cjb@laptop.org>

| | | | | | | | | | | | | | Rewrite mxs_dma_is_apbh and mxs_dma_is_apbx in order to support other SoCs like imx6q and reform the platform_device_id for the better further dt support.
