Merge tag 'armsoc-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

2015-09-01T19:18:40+00:00

Pull ARM SoC platform updates from Olof Johansson:
 "New or improved SoC support:

   - add support for Atmel's SAMA5D2 SoC
   - add support for Freescale i.MX6UL
   - improved support for TI's DM814x platform
   - misc fixes and improvements for RockChip platforms
   - Marvell MVEBU suspend/resume support

  A few driver changes that ideally would belong in the drivers branch
  are also here (acked by appropriate maintainers):

   - power key input driver for Freescale platforms (svns)
   - RTC driver updates for Freescale platforms (svns/mxc)
   - clk fixes for TI DM814/816X

  + a bunch of other changes for various platforms"

ARM: appropriate __init annotation for const data

2015-07-28T11:55:27+00:00

Init data marked const should be annotated with __initconst for
correctness and not __initdata.  In some cases the array gathering
references to that data has to be marked const as well. This fixes
LTO builds that otherwise fail with section mismatch errors.

ARM: STi: Remove platform call to trace_hardirqs_off()

2015-07-22T09:15:30+00:00

Calling trace_hardirqs_off() from the platform specific
secondary startup code as not been necessary since Dec 2010
when Russell King consolidated the call into the common SMP
code.

ARM: STi: Add code to release secondary cores from holding pen.

2015-07-22T09:14:18+00:00

Most upstream devs boot STi platform via JTAG which abuses the
boot process by setting the PC of secondary cores directly. As
a consquence, booting STi platforms via u-boot results in only
the primary core being brought up as the code to manage the
holding pen is not upstream.

This patch adds the necessary code to bring the secondary cores
out of the holding pen. It uses the cpu-release-addr DT property
to get the address of the holding pen from the bootloader.

With this patch booting upstream kernels via u-boot works
correctly:

[    0.045456] CPU: Testing write buffer coherency: ok
[    0.045597] CPU0: thread -1, cpu 0, socket 0, mpidr 80000000
[    0.045734] Setting up static identity map for 0x40209000 - 0x40209098
[    0.065047] CPU1: thread -1, cpu 1, socket 0, mpidr 80000001
[    0.065081] Brought up 2 CPUs
[    0.065089] SMP: Total of 2 processors activated (5983.43 BogoMIPS).
[    0.065092] CPU: All CPU(s) started in SVC mode.

ARM: STi: Add STiH410 SoC support

2015-03-11T14:34:45+00:00

This patch adds support to STiH410 SoC.

Please note "st,stih410" is already present in device tree.
The problem is that it is missing the entry in the match table,
and so the L2 cache and other cpus than 0 don't get initialized.

ARM: sti: always enable RESET_CONTROLLER

2015-02-18T11:20:29+00:00

A lot of the sti device drivers require reset controller support,
but do not all have individual 'depends on RESET_CONTROLLER'
statements. Using 'select' here once avoids a lot of build errors
resulting from this.

ARM: sti: Add STiH407 Kconfig entry to select STIH407_RESET

2014-10-31T08:58:58+00:00

The STiH407 is a STMicroelectronics Digital Consumer electronics
family, targetted at set-top-box and other audio/video applications.

This patch selects the reset controller driver for this family which
is essential to take various IP's on the SoC out of powerdown / reset.
