Subject: [PATCHv4 0/2] clk: socfpga: Add clock driver for Arria10

From: Dinh Nguyen <dinguyen@...nsource.altera.com>

Hi,

This patch series add the clock driver for the Arria10 platform. Although the
Arria10 SoC's clock framework has some similarities the Cyclone/Arria 5, the
differences are enough to warrant it's own driver, rather than polluting the
existing driver with platform lookups.

v4:
- Move syscon regmap lookup to gate_clk_init().
- Remove unused includes(linux/clk.h and linux/clkdev.h)
- Check return value of of_clk_add_provider
- Clean ups to address Stephen's comments

v3:
- Fix sparse warning of assigning an integer 0 instead of NULL to a pointer.

v2:
- Update the DTS bindings doucment to have the new Arria10 clocks.
- Add an l4_sys_free_clk node. The l4_sys_free_clk is similar to the
  l4_sp_clk, but cannot be gated.

Thanks,

Dinh Nguyen (2):
