Subject: [PATCH 01/29] ARM: i.MX5: Allow DT clock providers
Currently clock providers defined in the DT are not registered
on i.MX5 platforms since of_clk_init() is not called.
This is not a problem for the SOC's own clocks, which are registered
in code, but prevents the DT being used to define clocks for external
hardware.
Fix this by calling of_clk_init() and actually using the DT to obtain
the 4 SOC fixed clocks.
These are already defined in the DT but were previously just used to
manually obtain the rate.
Fall back to the old scheme for non DT platforms.
Since the same method may be useful for other i.MX platforms
implement the imx_obtain_fixed_clock() function in common code.
Actually changing other i.MX platforms to use this should be done
later by someone with access to the appropriate hardware.

Subject: [PATCH 02/29] ARM: i.MX6: add i.MX6 specific L2 cache configuration
To improve the performance and power consumption add an i.MX6
specific L2 cache initialization.
This configuration is taken from Freescale's kernel patch
"ENGR00153601 [MX6]Adjust L2 cache parameter" [1]
with two additional improvements:
a) The L2X0_POWER_CTRL has only the two bits we set. So no need
to read the register before. Remove the register read done
in Freescale's patch.
b) In the L2X0_PREFETCH_CTRL register, besides the double linefill (bit[30]),
additionally enable the instruction and data prefetch (bit[29-28]).

Subject: [PATCH 03/29] 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().

Subject: [PATCH 05/29] ARM: imx: move clk_prepare() out from mxc_restart()
It's inappropriate to call clk_prepare() in mxc_restart(), because the
restart routine could be called in atomic context. Move clk_get() and
clk_prepare() into mxc_arch_reset_init() and only have the atomic part
clk_enable() be called in mxc_restart().
As a result, mxc_arch_reset_init() needs to be called after clk gets
initialized.
While there, it also changes printk(KERN_ERR ...) to pr_err() and adds
__init annotation for mxc_arch_reset_init().

Subject: [PATCH 06/29] ARM: imx: create mxc_arch_reset_init_dt() for DT boot
The mxc_arch_reset_init() uses static mapping and calls clk_get_sys() to
get clock. It's suitable for non-DT boot but not for DT boot where
dynamic mapping and of_clk_get() should be used instead. Create
mxc_arch_reset_init_dt() as the DT variant of mxc_arch_reset_init(),
and change DT platforms to use it.

Subject: [PATCH 07/29] ARM: imx: add clock support for imx6sl
Add clock support for i.MX6 SoloLite. It uses the dtc marco support to
define all clock IDs in imx6sl-clock.h, which will be included by both
clock driver and device tree sources, so that the data will stay sync
all the time between kernel and DT.

Subject: [PATCH 10/29] ARM: imx: disable pll8_mlb in mx6q_clks
The MLB PLL clock's operation doesn't fit for clock framework and
it should be handled internally in MLB driver.
Remove initialization of pll8_mlb clock device but leave its
declaration in mx6q_clks to avoid affecting imx6q clock numbering.

Subject: [PATCH 14/29] ARM i.MX5: Add S/PDIF clocks
This patch adds the S/PDIF clocks for i.MX51 and i.MX53. Tested on i.MX53.
The i.MX51 has a second set of spdif_root clock dividers, and on i.MX53
there is an additional input to the spdif_xtal mux.

Subject: [PATCH 15/29] 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.

commit 84344b43c (ARM: i.MX5: Allow DT clock providers) introduce the following
sparse warning:
arch/arm/mach-imx/clk.c:12:43: warning: Using plain integer as NULL pointer
There is no need to initialize phandle, so remove it.

Subject: [PATCH 23/29] ARM: imx: add VF610 clock support
Add clock support for Vybrid VF610. It uses dtc macro support to
define all clock IDs in vf610-clock.h to keep clock IDs coherence
between kernel and DT.

+* Clock bindings for Freescale Vybrid VF610 SOC
+
+Required properties:
+- compatible: Should be "fsl,vf610-ccm"
+- reg: Address and length of the register set
+- #clock-cells: Should be <1>
+
+The clock consumer should specify the desired clock by having the clock
+ID in its "clocks" phandle cell. See include/dt-bindings/clock/vf610-clock.h
+for the full list of VF610 clock IDs.
+
+Examples:
+
+clks: ccm@4006b000 {
+ compatible = "fsl,vf610-ccm";
+ reg = <0x4006b000 0x1000>;
+ #clock-cells = <1>;
+};
+
+uart1: serial@40028000 {
+ compatible = "fsl,vf610-uart";
+ reg = <0x40028000 0x1000>;
+ interrupts = <0 62 0x04>;
+ clocks = <&clks VF610_CLK_UART1>;
+ clock-names = "ipg";
+};

Subject: [PATCH 25/29] ARM: imx: Remove mxc specific ulpi access ops
There are ulpi access ops implemented in drivers/usb/phy/phy-ulpi.c.
mxc access ops implement the same access operations within mach-imx. This
patch removes the mxc ulpi file and uses phy-ulpi instead for
imx_otg_ulpi_create.
phy-ulpi successfully tested with i.MX27 Phytec phyCARD-S (pca100).
