94715d5945 arm: omap: hwmod: add a new addr space in otg for writing to control module
The mailbox register for usb otg in omap is present in control module.
On detection of any events VBUS or ID, this register should be written
to send the notification to musb core.

Till we have a separate control module driver to write to control module,
omap2430 will handle the register writes to control module by itself. So
a new address space to represent this control module register is added
to usb_otg_hs.

b82b04e8eb ARM: OMAP: omap_device: Do not overwrite resources allocated by OF layer
With the new devices (like, AM33XX and OMAP5) we now only support
DT boot mode of operation and now it is the time to start killing
slowly the dependency on hwmod, so with this patch, we are starting
with device resources.
The idea here is implemented considering to both boot modes -
  - DT boot mode
    OF framework will construct the resource structure (currently
    does for MEM & IRQ resource) and we should respect/use these
    resources, killing hwmod dependency.
    If pdev->num_resources > 0, we assume that MEM & IRQ resources
    have been allocated by OF layer already (through DTB).

    Once DMA resource is available from OF layer, we should
    kill filling any resources from hwmod.

  - Non-DT boot mode
    Here, pdev->num_resources = 0, and we should get all the
    resources from hwmod (following existing steps)

8a3d895bfe OMAP4: TWL: add vdda_hdmi_dac regulator supply
HDMI requires vdda_hdmi_dac (vdac) power for operation. The regulator,
or the regulator supplying the vdac, has been enabled by default and
things have worked without the HDMI driver enabling the vdac.

I encountered the problem when implementing HDMI device tree support,
where the regulator was not enabled by default.

This patch adds the vdda_hdmi_dac to twl-common.c so that the HDMI
driver can use it.

cca35017ca OMAPDSS: HDMI: Move GPIO handling to HDMI driver
We currently manage HDMI GPIOs in the board files via
platform_enable/disable calls. This won't work with device tree, and in
any case the correct place to manage the GPIOs is in the HDMI driver.

This patch moves the handling of the GPIOs to the HDMI driver. The GPIO
handling is moved to the common hdmi.c file, and this probably needs to
be revisited when adding OMAP5 HDMI support to see if the GPIO handling
needs to be moved to IP specific files.

e534e871a9 ARM: OMAP4: Fix array size for irq_target_cpu
If NR_IRQS is less than MAX_IRQS, we end up writing past the
irq_target_cpu array in omap_wakeupgen_init():

/* Associate all the IRQs to boot CPU like GIC init does. */
for (i = 0; i < max_irqs; i++)
	irq_target_cpu[i] = boot_cpu;

This can happen if SPARSE_IRQ is enabled as by default NR_IRQS is
set to 16. Without this patch we're overwriting other data during
the boot.

Looks like a similar fix was posted by Benoit Cousson earlier
as "ARM: OMAP2+: wakeupgen: Fix wrong array size for irq_target_cpu"
but was lost.

c7a9b09b1a ARM: omap: allow building omap44xx without SMP
The new omap4 cpuidle implementation currently requires
ARCH_NEEDS_CPU_IDLE_COUPLED, which only works on SMP.

This patch makes it possible to build a non-SMP kernel
for that platform. This is not normally desired for
end-users but can be useful for testing.

Without this patch, building rand-0y2jSKT results in:

drivers/cpuidle/coupled.c: In function 'cpuidle_coupled_poke':
drivers/cpuidle/coupled.c:317:3: error: implicit declaration of function '__smp_call_function_single' [-Werror=implicit-function-declaration]

It's not clear if this patch is the best solution for
the problem at hand. I have made sure that we can now
build the kernel in all configurations, but that does
not mean it will actually work on an OMAP44xx.

df3d17e068 ARM: pmu: remove arm_pmu_type enumeration
The arm_pmu_type enumeration was initially introduced to identify
different PMU types in the system, the usual one being that on the CPU
(ARM_PMU_DEVICE_CPU). With the removal of the PMU reservation code and
the introduction of devicetree bindings for the CPU PMU, the enumeration
is no longer required.

This patch removes the enumeration and updates the various CPU PMU
platform devices so that they no longer pass an .id field referring
to identify the PMU type.

8fef6263ea ARM/ASoC: omap-mcbsp: Remove CLKR/FSR mux configuration code
Remove the feature to configure the CLKR/FSR mux on McBSP port with 6pin
configuration.
When moving to devicetree these callback can no longer be used in a clean
way anymore.
If a board require to change the 6pin port to work in 4pin setup it needs
to set up the mux in the board file.
For OMAP2/3:
u32 devconf0;

/* McBSP1 CLKR/FSR signal to be connected to CLKX/FSX pin */
devconf0 = omap_ctrl_readl(OMAP2_CONTROL_DEVCONF0);
devconf0 |=  OMAP2_MCBSP1_CLKR_MASK | OMAP2_MCBSP1_FSR_MASK;
omap_ctrl_writel(devconf0, OMAP2_CONTROL_DEVCONF0);

For OMAP4:
u32 mcbsp_pad;

/* McBSP4 CLKR/FSR signal to be connected to CLKX/FSX pin */
mcbsp_pad = omap4_ctrl_pad_readl(OMAP2_CONTROL_DEVCONF0);
mcbsp_pad |=  ((1 << 31) | (1 << 30));
omap4_ctrl_pad_writel(mcbsp_pad, OMAP2_CONTROL_DEVCONF0);

In case when the kernel is booted with DT blob the pinctrl-single will be
provided as soon as it is enabled on the platform.

9574f36fb8 OMAP/serial: Add support for driving a GPIO as DTR.
OMAP hardware doesn't provide a phyisical DTR line, but
some configurations may need a DTR line which tracks whether
the device is open or not.

So allow a gpio to be configured as the DTR line.
