The devices that can act as an interrupt controller like the
GPIO are going to be handled using the IRQ domain mechanism
in order to avoid the static IRQ mapping done so far inside
plat-omap/irqs.h.
Enable IRQ_DOMAIN by default to allow the drivers shared with
OMAP2+ to compile properly on OMAP1 platforms.

__kuser_cmpxchg64 has a return path using bx lr to get back to the caller.
This is actually ok since the code in question is predicated on
CONFIG_CPU_32v6K, but for the sake of consistency using the usr_ret
macro is probably better.

Linux uses two PMD entries for a PTE with the classic page table format,
covering 2MB range. However, the __pte_free_tlb() function only adds a
single TLB flush corresponding to 1MB range covering 'addr'. On
Cortex-A15, level 1 entries can be cached by the TLB independently of
the level 2 entries and without additional flushing a PMD entry would be
left pointing at the wrong PTE. The patch limits the TLB flushing range
to two 4KB pages around the 1MB boundary within PMD.

If we are context switched whilst copying into a thread's
vfp_hard_struct then the partial copy may be corrupted by the VFP
context switching code (see "ARM: vfp: flush thread hwstate before
restoring context from sigframe").
This patch updates the ptrace VFP set code so that the thread state is
flushed before the copy, therefore disabling VFP and preventing
corruption from occurring.

In a preemptible kernel, vfp_set() can be preempted, causing the
hardware VFP context to be switched while the thread vfp state is
being read and modified. This leads to a race condition which can
cause the thread vfp state to become corrupted if lazy VFP context
save occurs due to preemption in between the time thread->vfpstate
is read and the time the modified state is written back.
This may occur if preemption occurs during the execution of a
ptrace() call which modifies the VFP register state of a thread.
Such instances should be very rare in most realistic scenarios --
none has been reported, so far as I am aware. Only uniprocessor
systems should be affected, since VFP context save is not currently
lazy in SMP kernels.
The problem was introduced by my earlier patch migrating to use
regsets to implement ptrace.
This patch does a vfp_sync_hwstate() before reading
thread->vfpstate, to make sure that the thread's VFP state is not
live in the hardware registers while the registers are modified.
Thanks to Will Deacon for spotting this.

Following execution of a signal handler, we currently restore the VFP
context from the ucontext in the signal frame. This involves copying
from the user stack into the current thread's vfp_hard_struct and then
flushing the new data out to the hardware registers.
This is problematic when using a preemptible kernel because we could be
context switched whilst updating the vfp_hard_struct. If the current
thread has made use of VFP since the last context switch, the VFP
notifier will copy from the hardware registers into the vfp_hard_struct,
overwriting any data that had been partially copied by the signal code.
Disabling preemption across copy_from_user calls is a terrible idea, so
instead we move the VFP thread flush *before* we update the
vfp_hard_struct. Since the flushing is performed lazily, this has the
effect of disabling VFP and clearing the CPU's VFP state pointer,
therefore preventing the thread from being updated with stale data on
the next context switch.

This reverts commit 3c424f359898aff48c3d5bed608ac706f8a528c3.
Joachim Eastwood reports:
| "ARM: 7304/1: ioremap: fix boundary check when reusing static mapping"
| Commit: 3c424f359898aff48c3d5bed608ac706f8a528c3 in Linus master
|
| Breaks booting on my custom AT91RM9200 board.
| There isn't any error messages or anything that indicates what goes
| wrong it just stops after; Uncompressing Linux... done, booting the
| kernel.
|
| Reverting it makes my board boot again.
and further debugging reveals:
ioremap: pfn=fffff phys=fffff000 offset=400 size=1000
ioremap: area c3ffdfc0: phys_addr=200000 pfn=200 size=4000
ioremap: found: addr fef74000 => fed73000 => fed73400
Clearly, an area for pfn 0x200, 16K can't ever satisfy a request for pfn
0xfffff. This happens because the changed if statement becomes:
if (0x00200 > 0xfffff ||
0xfffff000 + 0x400 + 0x1000-1 > 0x00200000 + 0x4000-1)
and therefore:
if (0x00200 > 0xfffff ||
0x000003ff > 0x00203fff)
The if condition fails, and so we _believe_ that the SRAM mapping fits
our request. Clearly that's totally bogus.
Moreover, the original premise of the 'fix' patch was wrong:
| The condition checking boundaries of the requested and existing
| mappings didn't take in-page offset into consideration though,
| which lead to obscure and hard to debug problems when requested
| mapping crossed end of the static one.
as the code immediately above this loop does:
size = PAGE_ALIGN(offset + size);
so 'size' already contains the requested offset into the page.
So, revert the broken 'fix'.

Currently MMC2 setup code can only enable loopback clock and
relies on reset value for boards that need to have it disabled.
This causes a problem with certain bootloaders that always enable
that clock, resulting with unwanted bootloader dependencies.

hsmmc23_before_set_reg() can set MMCSDIO2ADPCLKISEL bit, which
enables internal clock for MMC2. Currently this function is also called
by code handling MMC3, and if .internal_clock is set in platform data
(by default it currently is), it will set MMCSDIO2ADPCLKISEL for MMC2
instead of MMC3 (MMC3 doesn't have such bit so nothing actually needs to
be done). This breaks 2nd SD slot on pandora.
Fix this by changing hsmmc23_before_set_reg() to only handle MMC2.
Note that this removes .remux() call for MMC3, but no board currently
needs it and it's also not called for MMC4 and MMC5.

Commit 2f0778af (ARM: 7205/2: sched_clock: allow sched_clock to be
selected at runtime) had a typo for the case when CONFIG_OMAP_32K_TIMER
is not set.
In dmtimer_read_sched_clock(), wrong argument was getting passed to
__omap_dm_timer_read_counter() function call; instead of "&clksrc",
we were passing "clksrc.io_base", which results into kernel crash.
To reproduce kernel crash, just disable the CONFIG_OMAP_32K_TIMER config
option (and DEBUG_LL) and build/boot the kernel.
This will use dmtimer as a kernel clocksource and lead to kernel
crash during boot -

Add missing iounmap in error handling code, in a case where the function
already preforms iounmap on some other execution path.
A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)
// <smpl>
@@
expression e;
statement S,S1;
int ret;
@@
e = \(ioremap\|ioremap_nocache\)(...)
... when != iounmap(e)
if (<+...e...+>) S
... when any
when != iounmap(e)
*if (...)
{ ... when != iounmap(e)
return ...; }
... when any
iounmap(e);
// </smpl>

A hardware bug in the OMAP4 HDMI PHY causes physical damage to the board
if the HDMI PHY is kept powered on when the cable is not connected.
This patch solves the problem by adding hot-plug-detection into the HDMI
IP driver. This is not a real HPD support in the sense that nobody else
than the IP driver gets to know about the HPD events, but is only meant
to fix the HW bug.
The strategy is simple: If the display device is turned off by the user,
the PHY power is set to OFF. When the display device is turned on by the
user, the PHY power is set either to LDOON or TXON, depending on whether
the HDMI cable is connected.
The reason to avoid PHY OFF when the display device is on, but the cable
is disconnected, is that when the PHY is turned OFF, the HDMI IP is not
"ticking" and thus the DISPC does not receive pixel clock from the HDMI
IP. This would, for example, prevent any VSYNCs from happening, and
would thus affect the users of omapdss. By using LDOON when the cable is
disconnected we'll avoid the HW bug, but keep the HDMI working as usual
from the user's point of view.

"hdmi_hpd" pin is muxed to INPUT and PULLUP, but the pin is not
currently used, and in the future when it is used, the pin is used as a
GPIO and is board specific, not an OMAP4 wide thing.
So remove the muxing for now.

The GPIO 60 on 4430sdp and Panda is not HPD GPIO, as currently marked in
the board files, but CT_CP_HPD, which is used to enable/disable HPD
functionality.
This patch renames the GPIO.

dss_core has to be initialized before any other DSS hwmod. Currently
this is broken as dss_core is listed in chip/revision specific hwmod
lists while other DSS hwmods are listed in common list which is
registered first.
This patch moves DSS hwmods (except for dss_core) to the separate list
which is registered last to ensure that dss_core is already registered.
This solves the problem with BUG() in L3 interrupt handler on boards
with DSS enabled in bootloader.
The long-term fix to this is to ensure modules are set up in dependency
order in the hwmod core code.

Commit 7b250aff1ce346b6c7bc0329a2350334d1c66525 ("ARM: OMAP: Avoid

is selected, and only compiling omap2430_init_early() when
CONFIG_SOC_OMAP2430 is selected.

To be able to get the memory resources by name from
the DMIC driver (for MPU and for DMA).
Without this patch, functionality that was working in 3.2 breaks in
3.3-rc1. This patch should have gone in as part of the 3.3 merge
window, but was inadvertently missed.
