* ARM: imx: add CPU clock typeLucas Stach2014-11-231-1/+1
| | | | | | | | | | | | | This implements a virtual clock used to abstract away all the steps needed in order to change the ARM clock, so we don't have to push all this clock handling into the cpufreq driver. While it will be used for i.MX53 at first it is generic enough to be used on i.MX6 later on. Signed-off-by: Lucas Stach <l.stach@pengutronix.de> Signed-off-by: Shawn Guo <shawn.guo@freescale.com>
* ARM: imx: add an exclusive gate clock typeShawn Guo2014-09-161-1/+2
| | | | | | | | | | | | | | | | There are a couple of gate clocks are mutually exclusive on i.MX6, i.e. LVDSCLK1_IBEN and LVDSCLK1_OBEN. They cannot be enabled simultaneously. This patches adds an exclusive gate clock type specifically for such case. The clock driver will need to call imx_clk_gate_exclusive() to register a gate clock with parameter exclusive_mask indicating the mask of gate bits which are mutually exclusive to this gate clock. Right now, it only handles the exclusive gate clocks which are defined in a single hardware register, which is the case we're running into today. But it can be extended to handle exclusive gate clocks defined in different registers later if needed. Signed-off-by: Shawn Guo <shawn.guo@freescale.com>

* ARM: imx6: fix SMP compilation againArnd Bergmann2014-08-181-0/+2
| | | | | | | | | | | | | | | | | My earlier patch 1fc593feaf8e ("ARM: imx: build i.MX6 functions only when needed") fixed a problem with building an i.MX5 kernel, but now the problem has returned for the case where we allow ARMv6K SMP builds in multiplatform. With CONFIG_CPU_V7 disabled, but i.MX3 and SMP enabled, we get this build error: arch/arm/mach-imx/built-in.o: In function `v7_secondary_startup': :(.text+0x5124): undefined reference to `v7_invalidate_l1' This puts the code inside of an "ifdef CONFIG_SOC_IMX6" to hopefully do the right thing in all configurations.

| | | | | | | | | i.MX6SL's suspend in ocram function is derived from i.MX6Q, it can lower the DDR IO power from ~10mA@1.2V to ~1mA@1.2V, measured on i.MX6SL EVK board, SH5. Signed-off-by: Anson Huang <b20788@freescale.com> Signed-off-by: Shawn Guo <shawn.guo@linaro.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When system enter suspend, we can set the DDR IO to high-Z state to save DDR IOs' power consumption, this operation can save many power(from ~26mA@1.5V to ~15mA@1.5V, measured on i.MX6Q SabreSD board, R25) of DDR IOs. To achieve that, we need to copy the suspend code to ocram and run the low level hardware related code(set DDR IOs to high-Z state) in ocram. If there is no ocram space available, then system will still do suspend in external DDR, hence no DDR IOs will be set to high-Z. The OCRAM usage layout is as below, ocram suspend region(4K currently): ======================== high address ====================== . . . ^ ^ ^ imx6_suspend code PM_INFO structure(imx6_cpu_pm_info) ======================== low address ======================= Reviewed-by: Sascha Hauer <s.hauer@pengutronix.de> Signed-off-by: Anson Huang <b20788@freescale.com> Signed-off-by: Shawn Guo <shawn.guo@linaro.org>

Software workaround: To prevent this issue from occurring, software should ensure that the ARM to IPG clock ratio is less than 12:5 (that is < 2.4x), before entering WAIT mode.

| | | | | | | | | | | | | | | Add machine support code for the Freescale IMX50 SoC. The IMX50 is quite similar to the Freescale IMX53, and contains many of the same periperhal hardware modules, at the same address offsets as the IMX53. (Notable exceptions are that the IMX50 contains no CAN bus hardware, less GPIO, no VPU, it does contain an Electrophoretic display controller though).

* | ARM: imx: cpuidle: use init/exit common routineDaniel Lezcano2013-04-231-1/+1
|/ | | | | | | | | | | | | | | The code intializes the cpuidle driver at different places. The cpuidle driver for : * imx5 : is in the pm-imx5.c, the init function is in cpuidle.c * imx6 : is in cpuidle-imx6q.c, the init function is in cpuidle.c and cpuidle-imx6q.c Instead of having the cpuidle code spread across different files, let's create a driver for each SoC and use the common register function.

* ARM: imx: move imx6q_cpuidle_driver into a separate fileShawn Guo2013-01-301-1/+5
| | | | | | | Move imx6q_cpuidle_driver into a separate file as more codes will be added when WAIT mode gets implemented as cpuidle. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
* ARM: imx: Remove mx508 supportFabio Estevam2013-01-291-1/+0
| | | | | | | | | | | | | Only mx508 based board is mach-mx50_rdp and it has been marked as BROKEN for several releases. mx508 currently lacks clock support. In case someone needs to add mx508 support back, then the recommended approach is to use device tree.

* ARM: imx: Remove mach-mx51_3ds boardFabio Estevam2013-01-291-1/+0
| | | | | | | | | | mach-mx51_3ds only supports old silicon version of MX51 and was replaced with mx51 babbage, which is the official MX51 development board. No need to maintain it anymore. Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com> Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
* ARM: imx: use debug_ll_io_init() for imx6qShawn Guo2013-01-291-1/+0
| | | | | | | Use debug_ll_io_init() to map low level debug port for imx6q, so that arch/arm/mach-imx/lluart.c can be removed. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
* ARM i.MX25: Add devicetree supportSascha Hauer2012-11-121-0/+1
| | | | | | | | This adds a i.MX25 dt machine descriptor and changes the clock support to optionally initialize from dt. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Acked-by: Shawn Guo <shawn.guo@linaro.org>
* ARM: imx: merge plat-mxc into mach-imxShawn Guo2012-10-151-0/+17
| | | | | | | | | | | | | It's really unnecessary to have plat-mxc, and let's merge it into mach-imx. It's pretty much just a bunch of file renaming and Kconfig/Makefile merge. To make the change less invasive, we keep using Kconfig symbol CONFIG_ARCH_MXC for mach-imx sub-architecture.

* ARM: imx: move platform device code into mach-imxShawn Guo2012-10-151-0/+2
| | | | | | | | | | It moves platform device code from plat-mxc into mach-imx. Along with that, header devices-common.h gets moved from plat-mxc/include/mach/ into mach-imx/devices/.
