f4b7094250 clk: imx: pllv3: add enable() support
Before set_rate() pllv3 needs enable() to power the pll up.
Add enable() taking into account different power_bit and
different powerup_set, because some pll needs its power_bit to be
set or reset to be powered on.

fddf876a8f mpc83xx_clk: always treat MPC83XX_CLK_PCI as invalid
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.

b2b1100a3b aspeed: ast2500: Read clock ofdata in the correct method
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.

77ed3c42fe clk: add clock driver for MediaTek MT76x8 platform
This patch adds a clock driver for MediaTek MT7628/7688 SoC.
It provides clock gate control as well as getting clock frequency for
CPU/SYS/XTAL and some peripherals.

Make sure that the clock self-assignment works by having a clock of
clk-sbox be configured automatically when clk-sbox is probed.

fd1ba29652 drivers: clk: Fix using assigned-clocks in the node of the clock it sets up
This fixes the case where assigned-clocks is used to define a clock
defaults inside this same clock's node. This is used sometimes to setup a
default parents and/or rate for a clock.

example:
muxed_clock: muxed_clock {
	clocks = <&clk_provider 0>, <&clk_provider 1>;
	#clock-cells = <0>;
	assigned-clocks = <&muxed_clock>;
	assigned-clock-parents = <&clk_provider 1>;
};

It doesn't work in u-boot because the assigned-clocks are setup *before*
the clock is probed. (clk_set_parent() will likely crash or fail if called
before the device probe function)
Making it work by handling "assigned-clocks" in 2 steps: first before the
clk device is probed, and then after the clk device is probed.

Add devm_clk_get(), devm_clk_get_optional() to get clocks from the
device-tree. The clocks is automatically released and the data structure
freed when the device is unbound.
Also add devm_clk_put() to release the clock and free the data structure
manually.

727fa4539c clk: Add support for I2C clocks on NXP's imx6q SoC which use CCF
This change adds support for I2C clock modeled in CCF. This code intention
is to only enable those clocks in the I2C driver with default settings.
For that reason the "busy" versions of clocks reuse the generic approach
and would need to be updated when one wants to adjust the I2C clock
frequency in U-Boot.
