      ARM: imx: add an exclusive gate clock type · 19d86344
      由 Shawn Guo 提交于 
      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.

      ARM: imx6: fix SMP compilation again · 060d517d
      由 Arnd Bergmann 提交于 
      My earlier patch 1fc593fe ("ARM: imx: build i.MX6 functions
only when needed") fixed a problem with building an i.MX5 kernel,
but now the problem has returned for the case where we allow
ARMv6K SMP builds in multiplatform. With CONFIG_CPU_V7 disabled,
but i.MX3 and SMP enabled, we get this build error:

arch/arm/mach-imx/built-in.o: In function `v7_secondary_startup':
:(.text+0x5124): undefined reference to `v7_invalidate_l1'

This puts the code inside of an "ifdef CONFIG_SOC_IMX6" to hopefully
do the right thing in all configurations.

      ARM: imx6: build pm-imx6q.c independently of CONFIG_PM · 28a9f3b0
      由 Shawn Guo 提交于 
      When building a kernel image with only CONFIG_CPU_IDLE but no CONFIG_PM,
we will get the following link error.

  LD      init/built-in.o
arch/arm/mach-imx/built-in.o: In function `imx6q_enter_wait':
platform-spi_imx.c:(.text+0x25c0): undefined reference to `imx6q_set_lpm'

platform-spi_imx.c:(.init.text+0x75d4): undefined reference to `imx6q_set_chicken_bit'
make[1]: *** [vmlinux] Error 1

Since pm-imx6q.c has been a collection of library functions that access
CCM low-power registers used by not only suspend but also cpuidle and
other drivers, let's build pm-imx6q.c independently of CONFIG_PM to fix
above error.

      ARM: imx: add support code for IMX50 based machines · 374daac4
      由 Greg Ungerer 提交于 
      Add machine support code for the Freescale IMX50 SoC.

The IMX50 is quite similar to the Freescale IMX53, and contains many of the
same periperhal hardware modules, at the same address offsets as the IMX53.
(Notable exceptions are that the IMX50 contains no CAN bus hardware, less
GPIO, no VPU, it does contain an Electrophoretic display controller though).

This support code uses some of the IMX53 setup code to reduce duplication
of what would be identical init IO setup.

      ARM: imx: v7_cpu_resume() is needed by imx6sl build · 5d482172
      由 Shawn Guo 提交于 
      Building a kernel with the following options,

  CONFIG_SMP=n
  CONFIG_PM=y
  CONFIG_SOC_IMX6SL=y
  CONFIG_SOC_IMX6Q=n

we will see the build error below.

  arch/arm/mach-imx/built-in.o: In function `imx6q_pm_enter':
  platform-spi_imx.c:(.text+0x2648): undefined reference to `v7_cpu_resume'
  make[1]: *** [vmlinux] Error 1

This is because that v7_cpu_resume() implemented in headsmp.S is also
needed by imx6sl build.  Let's build headsmp.S for CONFIG_SOC_IMX6SL as
well.

      ARM: imx: enable suspend for imx6sl · 9ba64fe3
      由 Shawn Guo 提交于 
      The imx6sl low power mode implementation inherits imx6q/dl one,
and pm-imx6q.c can just work for imx6sl with some minor updates.
Let's enable imx6sl suspend support by reusing pm-imx6q.c and use
cpu_is_imxXX() to handle the those minor differences between imx6sl
and imx6q/dl.

      ARM: imx: add common clock support for fixup mux · a49e6c4b
      由 Liu Ying 提交于 
      One register may have several fields to control some clocks. It
is possible that the read/write values of some fields may map to
different real functional values, so writing to the other fields
in the same register may break a working clock tree. A real case
is the aclk_podf field in the register 'CCM Serial Clock Multiplexer
Register 1' of i.MX6Q/SDL SoC. This patch introduces a fixup hook
for multiplexer clock which is called before writing a value to
clock registers to support this kind of multiplexer clocks.
