clk: clk_stm32: Add .set_rate callback

2018-01-29T17:48:33Z

Since 'commit f4fcba5c5baa ("clk: implement clk_set_defaults()")' STM32F4 family board can't boot. Above patch calls clk_set_rate() for all nodes with assigned-clock-rates property. Clock driver for STM32F family doesn't implement .set_rate callback which make clk_set_defaults() exit on error and prevent board to boot. Fixes: f4fcba5c5baa ("clk: implement clk_set_defaults()") Signed-off-by: Patrice Chotard

rockchip: clk: guard set_parent implementations against OF_PLATDATA

2018-01-28T16:12:39Z

The set_parent implementations do not make sense when OF_PLATDATA is enabled. We guard these against OF_PLATDATA and don't populate the set_parent-op when this is the case. Signed-off-by: Philipp Tomsich

clk: rockchip: clk_rk3368: Implement "assign-clock-parent"

clk: rockchip: clk_rk3288: Implement "assign-clock-parent" and "assign-clock-rate"

2018-01-28T16:12:39Z

The RK3288 CRU-node assigns rates to a number of clocks that are not implemented in the RK3288 clock-driver (but which have been sufficiently initialised from rkclk_init()): for these clocks, we implement the gmac clock set parent, but simply ignore the others' set_rate() operation and return 0 to signal success.

clk: implement clk_set_defaults()

2018-01-28T16:12:36Z

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.

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

rockchip: clk: rk3399: implement set_parent() operation

2018-01-28T16:12:36Z

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").
