78827ec071 ARM: dts: imx6qdl-sabresd: add always on pcie regulator
Everything in the PCI specification assumes devices to be
enumerable on startup. This is only possible if they have
power available.

A future improvement may allow this regulator to be switched
off for D3hot and D3cold power states, but there is a lot
of work to do the pcie host controller side for this to work.
To keep things simple always enable the regulator for now.

The Colibri VF61 is a module which needs a carrier board to actually

we should reflect this in the device tree files. This patch adds the

bad3db104f ARM: imx: source gpt per clk from OSC for system timer
On i.MX6Q TO > 1.0, i.MX6DL and i.MX6SX, gpt per clock
can be from OSC instead of ipg_per, as ipg_per's rate
may be scaled when system enter low bus mode, to keep
system timer NOT drift, better to make gpt per clock
at fixed rate, here add support for gpt per clock to
be from OSC which is at fixed rate always.

There are some difference on this implementation of
gpt per clock source, see below for details:

i.MX6Q TO > 1.0: GPT_CR_CLKSRC, b'101 selects fix clock
    of OSC / 8 for gpt per clk;
i.MX6DL and i.MX6SX: GPT_CR_CLKSRC, b'101 selects OSC
    for gpt per clk, and we must enable GPT_CR_24MEM to
    enable OSC clk source for gpt per, GPT_PR_PRESCALER24M
    is for pre-scaling of this OSC clk, here set it to 8
    to make gpt per clk is 3MHz;
i.MX6SL: ipg_per can be from OSC directly, so no need to
    implement this new clk source for gpt per.

Clock Generation in IMX6DQRM, i.e. both BYPASS_CLK_SRC and BYPASS bits
are implemented as mux clocks, and ENABLE bit of PLL clocks is

19d863446a ARM: imx: add an exclusive gate clock type
There are a couple of gate clocks are mutually exclusive on i.MX6, i.e.
LVDSCLK1_IBEN and LVDSCLK1_OBEN.  They cannot be enabled simultaneously.
This patches adds an exclusive gate clock type specifically for such
case.  The clock driver will need to call imx_clk_gate_exclusive() to
register a gate clock with parameter exclusive_mask indicating the mask
of gate bits which are mutually exclusive to this gate clock.

Right now, it only handles the exclusive gate clocks which are defined
in a single hardware register, which is the case we're running into
today.  But it can be extended to handle exclusive gate clocks defined
in different registers later if needed.

3b18dd7a86 ARM: imx: clk-vf610: introduce clks_init_on
At the end of the boot process, the clock framework might disable
required main PLL's. So far, this was no issue since drivers
requested clocks, which are descended of the main PLL's (e.g.
pll1_pfd1, which provides the system clock).

To archive the full 500MHz system clock, DDR clock need to be a
descendant of PLL2 rather than PLL1 (DDRC_CLK_SEL set to 0). The
bootloader sets up the clocks accordingly before making use of
DDR at all. However, in Linux, there is no driver using PLL2,
which lead to PLL2 being disabled by the clock framework.

With this patch, we make sure that the main system clock and the
DDR clock are initially enabled and are kept enabled.

05bdb8c90e Xtensa improvements for 3.17:
- support highmem on cores with aliasing data cache. Enable highmem on kc705
   by default;
 - simplify addition of new core variants (no need to modify Kconfig /
   Makefiles);
 - improve robustness of unaligned access handler and its interaction with
   window overflow/underflow exception handlers;
 - deprecate atomic and spill registers syscalls;
 - clean up Kconfig: remove orphan MATH_EMULATION, sort 'select' statements;
 - wire up renameat2 syscall.
 
 Various fixes:
 - fix address checks in dma_{alloc,free}_coherent (runtime BUG);
 - fix access to THREAD_RA/THREAD_SP/THREAD_DS (debug build breakage);
 - fix TLBTEMP_BASE_2 region handling in fast_second_level_miss (runtime
   unrecoverable exception);
 - fix a6 and a7 handling in fast_syscall_xtensa (runtime userspace register
   clobbering);
 - fix kernel/user jump out of fast_unaligned (potential runtime unrecoverabl
   exception);
 - replace termios IOCTL code definitions with constants (userspace build
   breakage).

 "Xtensa improvements for 3.17:
   - support highmem on cores with aliasing data cache.  Enable highmem
     on kc705 by default
   - simplify addition of new core variants (no need to modify Kconfig /
     Makefiles)
   - improve robustness of unaligned access handler and its interaction
     with window overflow/underflow exception handlers
   - deprecate atomic and spill registers syscalls
   - clean up Kconfig: remove orphan MATH_EMULATION, sort 'select'
     statements
   - wire up renameat2 syscall.

  Various fixes:
   - fix address checks in dma_{alloc,free}_coherent (runtime BUG)
   - fix access to THREAD_RA/THREAD_SP/THREAD_DS (debug build breakage)
   - fix TLBTEMP_BASE_2 region handling in fast_second_level_miss
     (runtime unrecoverable exception)
   - fix a6 and a7 handling in fast_syscall_xtensa (runtime userspace
     register clobbering)
   - fix kernel/user jump out of fast_unaligned (potential runtime
     unrecoverabl exception)
   - replace termios IOCTL code definitions with constants (userspace
     build breakage)"

Bisect points to commit 649671c90e ("unicore32: Use get_signal()

This code never even compiled.  Reverting the patch does not work, since
previously used functions no longer exist, so try to fix it up.  Compile
tested only.

19ed3eb975 ARM: SoC fixes for 3.17-rc
Here's the weekly batch of fixes from arm-soc.
 
 The delta is a largeish negative delta, due to revert of SMP support for Broadcom's
 STB SoC -- it was accidentally merged before some issues had been addressed, so they
 will make a new attempt for 3.18. I didn't see a need for a full revert of the whole
 platform due to this, we're keeping the rest enabled.
 
 The rest is mostly:
 
 * A handful of DT fixes for i.MX (Hummingboard/Cubox-i in particular)
 * Some MTD/NAND fixes for OMAP
 * Minor DT fixes for shmobile
 * Warning fix for UP builds on vexpress/spc
 
 There's also a couple of patches that wires up hwmod on TI's DRA7 SoC
 so it can boot. Drivers and the rest had landed for 3.17, and it's small
 and isolated so it made sense to pick up now even if it's not a bugfix.
