It would > mean we can move away from arm_global_timer for all upstreamed STI platforms. This patch-set only supports STiH4{07,10}, which is the only platform it's been tested on until this point. I can investigate porting it to Orly/Orly2 as a subsequent piece of work if it's going to be useful for ST. -- Lee Jones Linaro STMicroelectronics Landing Team Lead Linaro.org │ Open source software for ARM SoCs Follow Linaro: Facebook | Twitter | Blog
