2016-06-21ARM: imx6: fix static declaration in include/soc/imx/cpuidle.hBen Dooks
If both CONFIG_CPU_IDLE or CONFIG_SOC_IMX6Q are not set then the imx6q_cpuidle_fec_irqs_used() and other functions should be marked static inline to avoid the following warnings whilst building drivers/net/ethernet/freescale: include/soc/imx/cpuidle.h:21:6: warning: symbol 'imx6q_cpuidle_fec_irqs_used' was not declared. Should it be static? include/soc/imx/cpuidle.h:22:6: warning: symbol 'imx6q_cpuidle_fec_irqs_unused' was not declared. Should it be static?

2016-06-12ARM: imx6: disable deeper idle states when FEC is active w/o HW workaroundLucas Stach
The i.MX6 Q/DL has an erratum (ERR006687) that prevents the FEC from waking the CPUs when they are in wait(unclocked) state. As the hardware workaround isn't applicable to all boards, disable the deeper idle state when the workaround isn't present and the FEC is in use. This allows to safely run a kernel with CPUidle enabled on all i.MX6 boards. Signed-off-by: Lucas Stach <l.stach@pengutronix.de> Acked-by: David S.

2015-06-03ARM: imx: define an enum for gpt timer device typeShawn Guo
Define an enum for gpt timer device type in include/soc/imx/timer.h to tell the gpt block differences among SoCs. Update non-DT users (clock drivers) to pass the device type. As we now have include/soc/imx/timer.h, the declaration of mxc_timer_init() is moved into there as the best fit. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
2015-06-03ARM: imx: move revision definitions and declarations into a headerShawn Guo
The revision definitions and declarations are widely used by clock drivers. As a step of moving clock drivers out of arch/arm/mach-imx, let's create header include/soc/imx/revision.h to accommodate them. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
