I ended up applying the series without the clk driver now, please see https://git.kernel.org/pub/scm/linux/kernel/git/soc/soc.git/commit/?h=arm/newsoc&id=7cb7b8fe63393d77 No need to resend the series any more, please just work with the clk maintainers to get that driver included through their tree. If there are any issues with the patches that I merged, it's best to send bugfix patches that can be applied on top of the branch listed above, or a pull request based on that commit. For new features to be merged in a later release, e.g. patches to add device tree nodes for other on-chip components, or additional dts files, please base them on the coming -rc1 release when that is out.

This patch series add Sunplus SP7021 SoC support. Sunplus SP7021 is an ARM Cortex A7 (4 cores) based SoC. It integrates many peripherals (ex: UART, I2C, SPI, SDIO, eMMC, USB, SD card and etc.) into a single chip. It is designed for industrial control. SP7021 consists of two chips (dies) in a package. One is called C-chip (computing chip). It is a 4-core ARM Cortex A7 CPU. It adopts high-level process (22 nm) for high performance computing. The other is called P- chip (peripheral chip). It has many peripherals and an ARM A926 added especially for real-time control. P-chip is made for customers. It adopts low-level process (ex: 0.11 um) to reduce cost.
