2020-01-26clk: mediatek: use unsigned type for returning the clk rateFabien Parent
mtk_clk_find_parent_rate is calling clk_get_rate to know the rate of a parent clock. clk_get_rate returns a ulong, while mtk_clk_find_parent_rate returns an int. This implicit cast creates an issue for clock rates big enough to need the full 32 bits to store its data. When that happen the clk rate will become incorrect because of the implicit cast between ulong -> int -> ulong. This commit change the return type of mtk_clk_find_parent_rate to ulong.

2020-01-20clk: sci-clk: add slack to clk-set-rate passed to firmwareLokesh Vutla
Add slack to the clock frequency parameters passed to firmware within clk_set_rate. min-freq is changed to 0 and max-rate is changed to ULONG_MAX. This fixes certain issues with pll clock rounding when the firmware is not able to set the frequency exactly to the target, the current implementation fails if the available frequency is even 1Hz off the target. With the change, the firmware still tries its best to set the frequency as close as possible to the target.

2020-01-08mpc83xx_clk: always treat MPC83XX_CLK_PCI as invalidRasmus Villemoes
The current mpc83xx_clk driver is broken for any board for which mpc83xx_has_pci() is true, i.e. anything not MPC8308: When is_clk_valid() reports that MPC83XX_CLK_PCI is valid, init_all_clks() proceeds to call init_single_clk(), but that doesn't know about either MPC83XX_CLK_PCI or has any handling of the TYPE_SCCR_ONOFF mode correctly returned by retrieve_mode(). Hence init_single_clk() ends up returning -EINVAL, and the whole board hangs in serial_init(). The quickest fix is to simply pretend that clock is invalid for all, since nobody can have been relying on it. Adding proper support seems to be a bit more involved than just handling TYPE_SCCR_ONOFF: - The power-on-reset value of SCCR[PCICM] is 0, so mpc83xx_clk_enable() would probably need to be tought to enable the clock. - The frequency of PCI_SYNC_OUT is either SYS_CLK_IN or SYS_CLK_IN/2 depending on the CFG_CLKIN_DIV configuration input, but that can't be read from software, so to properly fill out ->speed[MPC83XX_CLK_PCI] I think one would need guidance from Kconfig or dtb.

2020-01-07aspeed: ast2500: Read clock ofdata in the correct methodSimon Glass
At present the clock driver reads its ofdata in the probe() method. This is not correct although it is often harmless. However in this case it causes a problem, something like this: - ast_get_scu() is called (from somewhere) to get the SCI address - this probes the clock - first sets up ofdata (which does nothing at present) - DM marks clock device as active - DM calls pinctrl - pinctrl probes and calls ast_get_scu() in ast2500_pinctrl_probe() - ast_get_scu() probes the clock, but sees it already marked as probed - ast_get_scu() accesses the clock's private data, with scu as NULL - DM calls clock probe function ast2500_clk_probe() which reads scu By putting the read of scu into the correct method, scu is read as part of ofdata setup, and everything is OK. Note: This problem did not matter until now since DM always probed all parents before reading a child's ofdata. The fact that pinctrl is a child of clock seems to trigger this strange bug.
