2013-10-21ARM: imx6: report soc info via soc deviceShawn Guo6-2/+98
The patch enables soc bus infrastructure and adds a function imx_soc_device_init() to report soc info via soc device interface for imx6qdl and imx6sl. With the support, user space can get soc related info by looking at sysfs like below. $ cat /sys/devices/soc0/machine Freescale i.MX6 Quad SABRE Smart Device Board $ cat /sys/devices/soc0/family Freescale i.MX $ cat /sys/devices/soc0/soc_id i.MX6Q $ cat /sys/devices/soc0/revision 1.2 Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
2013-10-21ARM: imx: use imx_init_revision_from_anatop() on imx6slShawn Guo2-1/+6
Add imx6sl support into imx_init_revision_from_anatop(), so that it can be used to initialize cpu type and revision on imx6sl. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
2013-10-21ARM: imx: add a common function to initialize revision from anatopShawn Guo3-31/+23
The patch creates a common function imx_init_revision_from_anatop() by merging imx6q_init_revision() and imx_anatop_get_digprog(), so that any SoC that encodes revision info in anatop can use it to initialize revision. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
2013-10-21ARM: imx6q: use common soc revision helpersShawn Guo3-12/+7
It calls imx_set_soc_revision() to set up soc revision in imx6q_init_revision(), and replaces all the occurrences of imx6q_revision() with common helper imx_get_soc_revision(). Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
2013-10-21ARM: imx: add soc revision helper functionsShawn Guo2-0/+14
Similar to what we do for cpu type, the patch adds helper functions imx_set_soc_revision() and imx_get_soc_revision() to maintain imx_soc_revision in cpu.c. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>

2013-09-19ARM: i.MX: change dev_id to cpu0 while registering cpu clockSudeep KarkadaNagesha2-2/+2
Currently all clkdev registration use "cpufreq-cpu0.0" as dev_id for cpu clock which refers to virtual platform device. It needs to be "cpu0" instead which is actual cpu0 device id. This patch changes the dev_id from "cpufreq-cpu0.0" to "cpu0".

2013-09-19cpufreq: imx6q-cpufreq: assign cpu_dev correctly to cpu0 deviceSudeep KarkadaNagesha1-2/+7
Commit cdc58d602d2e657602a90c190cbf745886c95977 "cpufreq: imx6q-cpufreq: remove device tree parsing for cpu nodes" assumed the pdev->dev is set to cpu0 device in the platform code. But it actually points to the virtual cpufreq-cpu0 platform device which is not present in the device tree. Most of the information needed by cpufreq is stored in cpu0 DT node. So cpu_dev must point to cpu0 device. This patch fixes the wrong assignment to cpu_dev.

2013-08-19clk: add CLK_SET_RATE_NO_REPARENT flagJames Hogan1-2/+3
Add a CLK_SET_RATE_NO_REPARENT clock flag, which will prevent muxes being reparented during clk_set_rate. To avoid breaking existing platforms, all callers of clk_register_mux() are adjusted to pass the new flag. Platform maintainers are encouraged to remove the flag if they wish to allow mux reparenting on set_rate.

2013-08-16ARM: imx: clk-pllv3: improve the timeout waiting methodPeter Chen1-4/+11
There are two improvements for this commit: - Add comparing pll lock condition after while loop. It can fix potential fake timeout problem caused by the code is just scheduled out before compare the timeout, and the time of scheduling out are more than one jiffies. - Move timeout assignment more close to compare the timeout. It can reduce the possibility the code is scheduled out, and the timeout can be more precise.

2013-08-16ARM: imx6: change some clocks to fixup clocksLiu Ying4-22/+50
All the clocks controlled by the register 'CCM Serial Clock Multiplexer Register 1' should be fixup clocks. This patch changes those clocks from basic multiplexer or divider clocks to fixup clocks. Signed-off-by: Liu Ying <Ying.Liu@freescale.com> Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
2013-08-16ARM: imx: add common clock support for fixup muxLiu Ying3-1/+112
One register may have several fields to control some clocks. It is possible that the read/write values of some fields may map to different real functional values, so writing to the other fields in the same register may break a working clock tree. A real case is the aclk_podf field in the register 'CCM Serial Clock Multiplexer Register 1' of i.MX6Q/SDL SoC. This patch introduces a fixup hook for multiplexer clock which is called before writing a value to clock registers to support this kind of multiplexer clocks.
