e2e927c823 Few trivial omap MMC regression fixes for card voltages where
the syscon areas for PBIAS regulator were missing "simple-bus"
 that prevents probing of the children in the mapped region.
 
 This probably was not noticed earlier as the bootloader has
 already configured the regulator for the card in the slot.

bf64dd262e ARM: ux500: add an SMP enablement type and move cpu nodes
The "cpus" node cannot be inside the "soc" node, while this
works for the CoreSight blocks, the early boot code will look
for "cpus" directly under the root node, so this is a hard
convention. So move the CPU nodes.

Augment the "reg" property to match what is actually in the
hardware: 0x300 and 0x301 respectively.

Then add an SMP enablement type to be used by the SMP init
code, "ste,dbx500-smp".

c1bfa985de ARM: dts: keystone: fix dt bindings to use post div register for mainpll
All of the keystone devices have a separate register to hold post
divider value for main pll clock. Currently the fixed-postdiv
value used for k2hk/l/e SoCs works by sheer luck as u-boot happens to
use a value of 2 for this. Now that we have fixed this in the pll
clock driver change the dt bindings for the same.

 second one will ensure that the hwmod code will wait for any

9a258afa92 ARM: OMAP2+: hwmod: Fix _wait_target_ready() for hwmods without sysc
For hwmods without sysc, _init_mpu_rt_base(oh) won't be called and so
_find_mpu_rt_port(oh) will return NULL thus preventing ready state check
on those modules after the module is enabled.

This can potentially cause a bus access error if the module is accessed
before the module is ready.

Fix this by unconditionally calling _init_mpu_rt_base() during hwmod
_init(). Do ioremap only if we need SYSC access.

Eventhough _wait_target_ready() check doesn't really need MPU RT port but
just the PRCM registers, we still mandate that the hwmod must have an
MPU RT port if ready state check needs to be done. Else it would mean that
the module is not accessible by MPU so there is no point in waiting
for target to be ready.

e.g. this fixes the below DCAN bus access error on AM437x-gp-evm.

82567c85d5 Samsung fixes for v4.2
From Krzysztof Kozlowski:
 1. Fix exynos3250 MIPI DSI display and MIPI CSIS-2 camera sensorx
    after adding support for PMU regmap in exynos-video-mipi driver
    (issue introduced in v4.0).
 2. Bring back cpufreq for exynos4210 after incomplete switch to
    cpufreq-dt driver in 4.2 merge window. The necessary DT changes
    for exynos4210 cpufreq was not applied to the same tree as rest
    of patchset because of multiple conflicts between clk and arm-soc
    trees. Unfortunately without the change the exynos4210 boards
    loose cpufreq feature.

9dd4f28f36 ARM: keystone: dts: fix dt bindings for PCIe
Currently PCIe DT bindings are broken. PCIe driver can't function
without having a SerDes driver that provide the phy configuration.
On K2E EVM, this causes problem since the EVM has Marvell SATA
controller present and with default values in the SerDes register,
it seems to pass the PCIe link check, but causes issues since
the configuration is not correct. The manifestation is that when
EVM is booted with NFS rootfs, the boot hangs. We shouldn't enable
PCIe on this EVM since to work, SerDes driver has to be present as
well. So by default, the PCIe DT binding should be disabled in SoC
specific DTS. It can be enabled in the board specific DTS when the
SerDes device driver is also present.

So fix the status of PCIe DT bindings in the SoC specific DTS to
"disabled". To enable PCIe, the status should be set to "ok" in
the EVM DTS file when SerDes driver support becomes available in
the upstream tree.

Since dm9000 driver added support for a vcc regulator, platform data
based platforms have their ethernet broken, as the regulator claiming
returns -EPROBE_DEFER and prevents dm9000 loading.

This patch fixes this for all pxa boards using dm9000, by using the
specific regulator_has_full_constraints() function.

This was discovered and tested on the cm-x300 board.

Audio-in was incorrectly routed to Line In. It should be Mic3L as per

Using mic-bias voltage at 2.0v (<0x1>) does not work for some reason. There
is no voltage seen on micbias (R127). Mic-bias voltage of 2.5v (<0x2>) works.
I see voltage of 2.475v across GND and micbias.

With these changes, I can record audio with a pair of proliferate TRRS earbuds.

Linus Walleij
1d8aca9df6 ARM: ux500: fix MMC/SD card regression
Ux500 is regressing due to commit
a21763a0b1
"pinctrl: nomadik: activate strict mux mode" which disallows
Nomadik GPIO 5 to be muxed in as a level shifter voltage select
pin, as it is currently described as being used for RX on UART1.

The behaviour is correct, instead the hardware config has been
incorrecly specified: UART1 is indeed unused on HREFv60plus and
Snowball and that is why HREFv60plus can use the pins it would
normally occupy as the voltage select line for the MMC/SD
levelshifter (Snowball uses it for I2C4).

The reason UART1 was anyway enabled on these platforms was
probably to secure the port enumeration to userspace. This
can be solved by using aliases (done in a separate patch) so
we can now deactivate UART1 and let MMC/SD use it properly
on HREFv60plus. We explicitly activate it only for the
older HREFprev60 board.

To complete, we set up the pin configuration for these pins
properly in the sdi0 node.

This enumerates the PL011 serial ports on the Ux500. This is
necessary to do if we want to remove one of the serial ports,
since userspace depends on console to be present on ttyAMA2
and we must not break userspace.

5aed4ee7cc ARM: dts: configure regulators for Gumstix Pepper
Boot process is halting in midway because some of the necessary voltage
regulators are deemed unused and subsequently powered off, leading to
a completely unresponsive system.

Most of the device nodes had correct voltage regulator attachments.
Yet these nodes had to set stricter enforcement on them through
'regulator-boot-on' and 'regulator-always-on' to function correctly.

The consumers of the regulators this commit affect are the followings:

	DCDC1: vdd_1v8 system supply, USB-PHY, and ADC
	DCDC2: Core domain
	DCDC3: MPU core domain
	 LDO1: RTC
	 LDO2: 3v3 IO domain
	 LDO3: USB-PHY; not a boot-time requirement
	 LDO4: LCD [16:23]

All but LDO3 need to be always-on for the system to be functional.

Additionally regulator-name properties have been added for the kernel to
display the name from the schematic. This will improve diagnostics.

3c20b827b1 ARM: dts: omap3: overo: Update LCD panel names
For Gumstix Overo COMs, the u-boot bootloader typically passes an
argument specifying the default display via the omapdss.def_disp
parameter.  When a default display is specified, DSS2 tries to match
this name with either the device tree label (e.g. label=dvi) or,
failing this, the device tree alias (e.g. label=display0). Update the
panel names for the 'lcd43' and 'lcd35' displays in the device tree
such that they match the names passed by u-boot.

Linus Torvalds
01e2d0627a Revert "drm/i915: Use crtc_state->active in primary check_plane func"
This reverts commit dec4f799d0.

Jörg Otte reports a NULL pointder dereference due to this commit, as
'crtc_state' very much can be NULL:

        crtc_state = state->base.state ?
                intel_atomic_get_crtc_state(state->base.state, intel_crtc) : NULL;

So the change to test 'crtc_state->base.active' cannot possibly be
correct as-is.

There may be some other minimal fix (like just checking crtc_state for
NULL), but I'm just reverting it now for the rc2 release, and people
like Daniel Vetter who actually know this code will figure out what the
right solution is in the longer term.

75a6f82a0d freeing unlinked file indefinitely delayed
Normally opening a file, unlinking it and then closing will have
the inode freed upon close() (provided that it's not otherwise busy and
has no remaining links, of course).  However, there's one case where that
does *not* happen.  Namely, if you open it by fhandle with cold dcache,
then unlink() and close().

	In normal case you get d_delete() in unlink(2) notice that dentry
is busy and unhash it; on the final dput() it will be forcibly evicted from
dcache, triggering iput() and inode removal.  In this case, though, we end
up with *two* dentries - disconnected (created by open-by-fhandle) and
regular one (used by unlink()).  The latter will have its reference to inode
dropped just fine, but the former will not - it's considered hashed (it
is on the ->s_anon list), so it will stay around until the memory pressure
will finally do it in.  As the result, we have the final iput() delayed
indefinitely.  It's trivial to reproduce -

void flush_dcache(void)
{
        system("mount -o remount,rw /");
}

static char buf[20 * 1024 * 1024];

main()
{
        int fd;
        union {
                struct file_handle f;
                char buf[MAX_HANDLE_SZ];
        } x;
        int m;

        x.f.handle_bytes = sizeof(x);
        chdir("/root");
        mkdir("foo", 0700);
        fd = open("foo/bar", O_CREAT | O_RDWR, 0600);
        close(fd);
        name_to_handle_at(AT_FDCWD, "foo/bar", &x.f, &m, 0);
        flush_dcache();
        fd = open_by_handle_at(AT_FDCWD, &x.f, O_RDWR);
        unlink("foo/bar");
        write(fd, buf, sizeof(buf));
        system("df .");			/* 20Mb eaten */
        close(fd);
        system("df .");			/* should've freed those 20Mb */
        flush_dcache();
        system("df .");			/* should be the same as #2 */
}

will spit out something like
Filesystem     1K-blocks   Used Available Use% Mounted on
/dev/root         322023 303843      1131 100% /
Filesystem     1K-blocks   Used Available Use% Mounted on
/dev/root         322023 303843      1131 100% /
Filesystem     1K-blocks   Used Available Use% Mounted on
/dev/root         322023 283282     21692  93% /
- inode gets freed only when dentry is finally evicted (here we trigger
than by remount; normally it would've happened in response to memory
pressure hell knows when).
