2018-01-28rockchip: clk: rk3399: accept all assigned-clocks from the 'cru'-nodePhilipp Tomsich
The RK3399 CRU-node assigns rates to a number of clocks that are not implemented in the RK3399 clock-driver (but which have been sufficiently initialised from rkclk_init()): for these clocks, we simply ignore the set_rate() operation and return 0 to signal success.

2018-01-28clk: implement clk_set_defaults()Philipp Tomsich
Linux uses the properties 'assigned-clocks', 'assigned-clock-parents' and 'assigned-clock-rates' to configure the clock subsystem for use with various peripheral nodes. This implements clk_set_defaults() and hooks it up with the general device probibin in drivers/core/device.c: when a new device is probed, clk_set_defaults() will be called for it and will process the properties mentioned above. Note that this functionality is designed to fail gracefully (i.e. if a clock-driver does not implement set_parent(), we simply accept this and ignore the error) as not to break existing board-support. Signed-off-by: Philipp Tomsich <philipp.tomsich@theobroma-systems.com> Tested-by: David Wu <david.wu@rock-chips.com> Series-changes: 2 - Fixed David's email address. Series-version: 2 Cover-letter: clk: support assigned-clock, assigned-clock-parents, assigned-clock-rates For various peripherals on Rockchip SoCs (e.g. for the Ethernet GMAC), the parent-clock needs to be set via the DTS. This adds the required plumbing and implements the GMAC case for the RK3399. END
2018-01-28rockchip: clk: rk3399: implement set_parent() operationPhilipp Tomsich
This implements the (newly added) set_parent() operation for the RK3399 with a focus on allowing the RGMII clock parent to be configured via the assigned-clock-parents property of the GMAC node. This implementation supports only the GMAC (in fact only the RGMII clock parent) and allows to set this clock's parent either to the internal SCLK_GMAC or to an external clock input (identifiable by it providing a 'clock-output-name' of "gmac_clkin").

2018-01-28clk: refactor clk_get_by_index() into clk_get_by_indexed_prop()Philipp Tomsich
The logic in clk_get_by_index() may be useful for other properties than 'clocks': e.g. 'assigned-clocks' and 'assigned-clock-parents' follows the same model. This commit refactors clk_get_by_index() by introducing an internal function clk_get_by_indexed_prop() that allows to specify the name of the property to process. The original clk_get_by_index() call is simply directed through this helper function with the property name fixed to "clocks".
