If there are no _true_ dependencies and the MFD changes can be added independently without fear of build breakages, let me know and I'll apply them separately. --=20 Lee Jones Linaro STMicroelectronics Landing Team Lead Linaro.org =E2=94=82 Open source software for ARM SoCs =46ollow Linaro: Facebook | Twitter | Blog
