next/soc From Christian Daudt, BCM changes for 3.13/soc. Mostly cleanups and renaming of kernel config options, pushing down the mobile platforms one level in the naming scheme, keeping ARCH_BCM as a wider family config option. * tag 'bcm-for-3.13-soc2' of git://github.com/broadcom/bcm11351: ARM: bcm_defconfig: Run "make savedefconfig" ARM: bcm281xx: Add ARCH Timers to config rename ARCH_BCM to ARCH_BCM_MOBILE (mach-bcm) ARM: bcm281xx: more descriptive machine string ARM: bcm281xx: Enable GPIO driver Signed-off-by: Olof Johansson <olof@lixom.net>

Currently ARCH_BCM has been used for Broadcom Mobile V7 based SoCs. In order to allow other Broadcom SoCs to also use mach-bcm directory and files, this patch renames the original ARCH_BCM to ARCH_BCM_MOBILE, and uses ARCH_BCM to define any Broadcom chip residing in mach-bcm directory.

2013-10-21ARM: imx: enable suspend for imx6slShawn Guo5-1/+21
The imx6sl low power mode implementation inherits imx6q/dl one, and pm-imx6q.c can just work for imx6sl with some minor updates. Let's enable imx6sl suspend support by reusing pm-imx6q.c and use cpu_is_imxXX() to handle the those minor differences between imx6sl and imx6q/dl. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
2013-10-21ARM: imx: ensure dsm_request signal is not asserted when setting LPMShawn Guo3-2/+31
There is a defect in imx6 LPM design. When SW tries to enter low power mode with following sequence, the chip will enter low power mode before A9 CPU execute WFI instruction: 1. Set CCM_CLPCR[1:0] to 2'b00; 2. ARM CPU enters WFI; 3. ARM CPU wakeup from an interrupt event, which is masked by GPC or not visible to GPC, such as interrupt from local timer; 4. Set CCM_CLPCR[1:0] to 2'b01 or 2'b10; 5. ARM CPU execute WFI. Before the last step, the chip will enter WAIT mode if CCM_CLPCR[1:0] is set to 2'b01, or enter STOP mode if CCM_CLPCR[1:0] is set to 2'b10. The patch implements a recommended workaround for this issue. 1. SW triggers irq #32(IOMUX) to be always pending manually by setting IOMUX_GPR1_GINT bit; 2. SW should then unmask it in GPC before setting CCM LPM; 3. SW should mask it right after CCM LPM is set (bit0-1 of CCM_CLPCR). Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
2013-10-21ARM: imx6q: call WB and RBC configuration from imx6q_pm_enter()Shawn Guo1-15/+4
The WB and RBC configuration calls are currently made from imx6q_set_lpm() for WAIT_CLOCKED and WAIT_UNCLOCKED mode with a simple state tracking. This becomes unnecessary since we can make the calls from imx6q_pm_enter() directly now for suspend. More importantly, the current call of imx6q_enable_wb() from imx6q_set_lpm() is buggy. The CLPCR register bits configured by imx6q_enable_wb() will get lost, because imx6q_set_lpm() caches the same register and write it back at the end of the function. That's why the imx6dl suspend/resume does not work currently - the wakeup from suspend triggers a reset on imx6dl. Moves the WB and RBC calls into imx6q_pm_enter() to save the state tracking and fixes above bug, so that suspend/resume can start working on imx6dl. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
2013-10-21ARM: imx6q: move low-power code out of clock driverShawn Guo3-154/+156
The LPM (Low Power Mode) code that currently sits in imx6q clock driver will be reused by imx6sl. Let's move it into pm-imx6q.c, so that we can keep clock driver SoC specific and reuse pm-imx6q.c on imx6sl. In order to avoid adding another ioremap for CCM block, imx6q_pm_set_ccm_base() is created to let clock driver set up ccm_base for pm code. During the move, the unused CCGR macros get removed.

2013-10-21ARM: imx: reset core along with enable/disable operationShawn Guo1-0/+1

2013-10-21ARM: imx: do not return from imx_cpu_die() callShawn Guo1-1/+3
When imx_cpu_die() is being called, the cpu should never return from the call but just in WFI and wait for hardware to take it down. So let's do cpu_do_idle() repeatly in the call. Doing this help improve the relibility of hotplug operation. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>

2013-10-21ARM: imx: replace imx6q_restart() with mxc_restart()Shawn Guo3-32/+12
The imx6q_restart() works fine with normal reboot but will run into problem with emergency reboot like sysrq-b. In that case, of_iomap() gets called from interrupt context and hence triggers the BUG_ON in __get_vm_area_node(). Actually, since commit c1e31d1 (ARM: imx: create mxc_arch_reset_init_dt() for DT boot), imx6q/dl should try to use mxc_restart() by calling mxc_arch_reset_init_dt() beforehand, where things like of_iomap() can be done. The patch updates mxc_restart() a little bit to get it work for imx6q/dl and kill imx6q_restart() completely.
