The APBS clock on sun9i is the same as the APB0 clock on sun8i. With sun9i we are supporting the PRCM clocks by using CLK_OF_DECLARE, instead of through a PRCM mfd device and subdevices for each clock and reset control. As such we need a CLK_OF_DECLARE version of the sun8i-a23-apb0-clk driver. Also, build it for sun9i/A80, and not just for configurations with MFD_SUN6I_PRCM enabled.

The H3 clock control unit is similar to the those of other sun8i family members like the A23. It adds a new bus gates clock similar to the simple gates, but with a different parent clock for each single gate. Some of the gates use the new AHB2 clock as parent, whose clock source is muxable between AHB1 and PLL6/2. The documentation isn't totally clear about which devices belong to AHB2 now, especially USB EHIC/OHIC, so it is mostly based on Allwinner kernel source code.

On the A10, bit 15 controls the system's DRAM clock output (possibly to the DRAM chips), which we need to keep on. On the A20 this has been moved to the DRAM controller, becoming a no-op.

2015-12-02clk: sunxi: pll2: Fix clock running too fastMaxime Ripard1-18/+5
Contrary to what the datasheet says, the pre divider doesn't seem to be incremented by one in the PLL2, but just uses the value from the register, with 0 being a bypass. This fixes the audio playing too fast. Since we now have the same pre-divider flags, and the only difference with the A10 is the post-divider offset, also remove the structure to just pass the offset as an argument.

2015-12-02clk: let of_clk_get_parent_name() fail for invalid clock-indicesMasahiro Yamada1-0/+3
Currently, of_clk_get_parent_name() returns a wrong parent clock name when "clock-indices" property exists and the target index is not found in the property. In this case, NULL should be returned. For example, oscillator { compatible = "myclocktype"; #clock-cells = <1>; clock-indices = <1>, <3>; clock-output-names = "clka", "clkb"; }; consumer { compatible = "myclockconsumer"; clocks = <&oscillator 0>, <&oscillator 1>; }; Currently, of_clk_get_parent_name(consumer_np, 0) returns "clka" (and of_clk_get_parent_name(consumer_np, 1) also returns "clka", this is correct). Because the "clock-indices" in the clock parent does not contain <0>, of_clk_get_parent_name(consumer_np, 0) should return NULL.

2015-12-02ARM: imx: clk-vf610: fix SAI clock treeStefan Agner1-4/+4
The Synchronous Audio Interface (SAI) instances are clocked by independent clocks: The bus clock and the audio clock (as shown in Figure 51-1 in the Vybrid Reference Manual). The clock gates in CCGR0/CCGR1 for SAI0 through SAI3 are bus clock gates, as access tests to the registers with/without gating those clocks have shown. The audio clock is gated by the SAIx_EN gates in CCM_CSCDR1, followed by a clock divider (SAIx_DIV). Currently, the parent of the bus clock gates has been assigned to SAIx_DIV, which is not involved in the bus clock path for the SAI instances (see chapter 9.10.12, SAI clocking in the Vybrid Reference Manual). Fix this by define the parent clock of VF610_CLK_SAIx to be the bus clock. If the driver needs the audio clock (when used in master mode), a fixed device tree is required which assign the audio clock properly to VF610_CLK_SAIx_DIV.

2015-12-02clk: rockchip: Force rk3368 PWM clock (and its parents) onCaesar Wang1-0/+5
Most rk3368 boards (especially those with Pmic that followed the lead from rk3368-evb-act8846) have a PWM regulator on them for vdd_logic. This is the main voltage for all kinds of misc stuff including the memory controller. On these boards it is critically important to make sure that the PWM never ever glitches and never loses its clock. Any glitch could crash the system. Right now there are no users of the PWM regulator and also Linux thinks that the PWM regulator is disabled. Things happen to work because firmware configured the PWM and Linux doesn't touch it. ..and the PWM's clock is marked as "ignore unused". ...but things _stop_ working if we turn off serial console. Why? Because: 1. Serial console shares a parent clock with the PWM (pclk_cpu) 2. If we have no serial console then nobody is holding pclk_cpu on at reboot time. It gets disabled. We need to fix a lot of the above problems, but until we get everything right the cleanest "hack" seems like it is to just keep the "rk_pwm" clock on always.

2015-12-01clk: mmp: stop using platform headersArnd Bergmann3-19/+19
The mmp clock drivers currently hardcode the physical addresses for the clock registers. This is generally a bad idea, and it also gets in the way of multiplatform builds, which make the platform header files inaccessible to device drivers. To work around the header file problem, this patch changes the calling convention so the three mmp clock drivers get initialized with the base addresses as arguments from the platform code. It would still be useful to have a larger rework of the clock drivers, with DT integration to let the clocks actually be probed automatically, and the base addresses passed as DT properties. I am unsure if anyone is still interested in the mmp platform, so it is possible that this won't happen.

2015-12-01clk: rockchip: switch PLLs to slow mode before reboot for rk3288Chris Zhong1-18/+14
We've been seeing some crashes at reboot test on rk3288-based systems, which boards have not reset pin connected to NPOR, they reboot by setting 0xfdb9 to RK3288_GLB_SRST_FST register. If the APLL works in a high frequency mode, some IPs might hang during soft reset.

When we use a clk divider with a divider table, we limit the maximum divider value in divider_get_val() to the div_mask(width), but when we calculate the divider in divider_round_rate() we don't consider that the maximum divider may be limited by the width. Pass the width along to _get_table_maxdiv() so that we only return the maximum divider that is valid. This is useful for clocks that want to share the same divider table while limiting the available dividers to some subset of the table depending on the width of the bitfield.

2015-11-25clk: imx: clk-imx6q: Let OSC to be routed to anaclk2/2bMichael Trimarchi1-1/+2
OSC can be used as USB hub source clock. An example we can route to CLK2_P imx6 pin. This show a usage example: [...] usb_hub: usb-hub { compatible = "smsc,usb3503a"; clocks = <&clks IMX6QDL_CLK_LVDS2_GATE>; clock-names = "refclk"; }; }; [...] &clks { assigned-clocks = <&clks IMX6QDL_CLK_LVDS2_SEL>; assigned-clock-parents = <&clks IMX6QDL_CLK_OSC>; }; /sys/kernel/debug/clk/clk_summary osc 5 5 24000000 0 0 [...] lvds2_sel 1 1 24000000 0 0 lvds2_gate 1 1 24000000 0 0 [...] Signed-off-by: Michael Trimarchi <michael@amarulasolutions.com> Reviewed-by: Lucas Stach <l.stach@pengutronix.de> Signed-off-by: Shawn Guo <shawnguo@kernel.org>
2015-11-25clk: imx: add 'is_prepared' clk_ops callback for pllv3 clkBai Ping1-0/+14
Add 'is_prepared' callback function for pllv3 type clk to make sure when the system is bootup, the unused clk is in a known state to match the prepare count info.

2015-11-25clk: imx25: Remove osc clock from driverMarkus Pargmann1-16/+2
The 'osc' clock is already initialized by the fixed clock defined in imx25.dtsi. The imx25 clock driver tries to add this clock for a second time and fails with -EEXIST: i.MX clk 1: register failed with -17 As the clock is already properly setup in DT with a different driver, we can completely remove the handling in the imx25 clock driver.

2015-11-24clk: ti: drop locking code from mux/divider driversGrygorii Strashko2-25/+6
TI's mux and divider clock drivers do not require locking and they do not initialize internal spinlocks. This code was occasionally copy-posted from generic mux/divider drivers. So remove it.
