[PATCH v2 0/3] Add Rockchip Soc PWM driver

[Beniamino Galvani]

This series adds support for the PWM controller found on Rockchip
RK29, RK30 and RK31 SoCs. It is based on the documentation publicly
available [0] and kernel sources from Rockchip [1] and has been tested
on RK3188.

The last patch, which adds device tree nodes in the dts, depends on
the clocks introduced by Heiko in his recent submission of a new clk
driver for Rockchip RK3188.

    - fix MODULE_DEVICE_TABLE name
    - make pwm_ops struct const
    - indentation and cosmetics
