Shawn Guo 12aad63ca4 ARM: imx6q: call of_clk_init() to register fixed rate clocks

Dirk Behme fbcb441217 ARM: i.MX6: clk: add different DualLite MLB clock config
The CCM_CBCMR register (address 0x02C4018) has different meaning
between the i.MX6 Quad/Dual and the i.MX6 Solo/DualLite.

Compared to the i.MX6 Quad/Dual, the CCM_CBCMR register in the
i.MX6 Solo/DualLite reuses the gpu2d_core bits for the MLB clock
configuration.

Dirk Behme 2e603ad984 ARM: i.MX6: clk: add i.MX6 DualLite differences
The CCM_CBCMR register (address 0x02C4018) has different meaning
between the i.MX6 Quad/Dual and the i.MX6 Solo/DualLite.

Compared to the i.MX6 Quad/Dual, the CCM_CBCMR register in the
i.MX6 Solo/DualLite doesn't have a gpu3d_shader configuration and
moves the gpu2_core configuration at that place.

Handle these i.MX6 Quad/Dual vs. i.MX6 Solo/DualLite clock differences
by using cpu_is_mx6dl().

Dirk Behme 0e574461c4 ARM i.MX6: correct MLB clock configuration
According to the i.MX6 Dual/Quad technical reference manual
(Figure 18-2. Clock Tree - Part 1) the MLB clock is directly
feed by the AXI_CLK_ROOT. This is called 'axi' in our code.

Note that the clock of the MLB IP block on the i.MX6 is completely
independent of the PLL8 (MLB PLL). The MLB PLL isn't responsible
for feeding the MLB IP block with a clock. Instead, it's used
internally by the MLB module to sync the bus clock in case the MLB
6-pin interface is enabled:

MediaLB Control 0 Register, MLB150_MLBC0[5], MLBPEN:
1 MediaLB 6-pin interface enabled. MLB PLL and MLB PHY is enabled in this case.

I.e. the PLL8 MLB PLL has to be handled by the MLB driver and isn't needed
for clocking the MLB module itself.

Anson Huang 263475d4e0 ARM: imx: enable RBC to support anatop LPM mode
RBC is to control whether some ANATOP sub modules
can enter lpm mode when SOC is into STOP mode, if
RBC is enabled and PMIC_VSTBY_REQ is set, ANATOP
will have below behaviors:

1. Digital LDOs(CORE, SOC and PU) are bypassed;
2. Analog LDOs(1P1, 2P5, 3P0) are disabled;

As the 2P5 is necessary for DRAM IO pre-drive in
STOP mode, so we need to enable weak 2P5 in STOP
mode when 2P5 LDO is disabled.

For RBC settings, there are some rules as below
due to hardware design:

1. All interrupts must be masked during operating
   RBC registers;
2. At least 2 CKIL(32K) cycles is needed after the
   RBC setting is changed.

Shawn Guo 2bb4b70b1d ARM: imx: provide twd clock lookup from device tree
While booting from device tree, imx6q used to provide twd clock lookup
by calling clk_register_clkdev() in clock driver.  However, the commit
bd60345 (ARM: use device tree to get smp_twd clock) forces DT boot to
look up the clock from device tree.  It causes the failure below when
twd driver tries to get the clock, and hence kernel has to calibrate the
local timer frequency.

 smp_twd: clock not found -2
 ...
 Calibrating local timer... 396.13MHz.

clk_register_clkdev for that clock.

Since clock DT support which is meant to resolve clock lookup in device
tree is in place, the patch moves imx6q client devices' clock lookup
over to device tree, so that any new lookup to be added at later time
can just get done in DT instead of kernel.

Philipp Zabel 16339464c5 ARM i.MX6q: Add virtual 1/3.5 dividers in the LDB clock path
The ldb_di[01]_podf is implemented as a clk-divider that
divides by 1 or 2. In reality, the ldb_di[01]_ipu_div
dividers divide by either 3.5 or 7. Adding a fixed factor
of 1/3.5 fixes their children's clock rates.

This should probably be converted to rate table based dividers,
once available.

Linus Torvalds 4f2d658b2f arm-soc: device tree description updates
This branch contains two kinds of updates: Some platforms in the process
 of getting converted to device tree based booting, and the platform
 specific patches necessary for that are included here. Other platforms
 are already converted, so we just need to update the actual device
 tree source files and the binding documents to add support for new board
 and new drivers.
 In the future we will probably separate those into two branches, and
 in the long run, the plan is to move the device tree source files out
 of the kernel repository, but that has to wait until we have completed
 a much larger portion of the binding documents.

added clkdev registers next to a few removed unnecessary ones.

When moving to common clk framework, the imx6q clks rom and mmdc_ch1_axi
get different on/off states than old clk driver, which breaks suspend
