      ARM: Dove: Fixup ge00 initialisation · 30e0f580
      由 Hannes Reinecke 提交于 
      The last argument of orion_ge00_init() is actually the error
interrupt, so we should be using the correct value here.

      ARM: Kirkwood: Fix PHY disable clk problems · b5409430
      由 Simon Baatz 提交于 
      Commit 98d9986c (ARM: Kirkwood: Replace clock gating) and the fix 5fb2ce
(ARM: Kirkwood: clk_register_gate_fn: add fn assignment) introduced a custom
variant of clock gating which allows to define a function to be called
before gating the clock off.

This is used to disable the SATA and PCIe PHYs if the respective clocks
are unused after initialization.

However, of these two drivers, the SATA driver may be compiled as a module.
The driver re-enables the clocks at module init but the PHYs stay disabled.

Since the custom clock gating disabled the PHYs when gating the clock off,
it should also re-enable them when enabling the clock gate.  This is done by
adding a second function that may be used to enable the PHYs.

      ARM: Kirkwood: Ensure runit clock always ticks. · f479db44
      由 Andrew Lunn 提交于 
      Marvell engineers tell us:

	It seems that many units use the RUNIT clock.
	SPI, UART, NAND, TWSI, ...
	So it's not possible to clock gate it.

Currently the SPI, NAND and TWSI driver will clk_prepaure_enable()
this clk, but since we have no idea what ... is, and turning this clk
off results in a hard lock, unconditionally enable runit.

      ARM: EXYNOS: register devices in 'need_restore' state for pm_domains · ebc35c72
      由 Marek Szyprowski 提交于 
      Commit ca1d72f0 ('PM / Domains: Make it possible to add devices to
inactive domains') introduced possibility to add devices to inactive
power domains and added pm_genpd_dev_need_restore() function which lets
platform core to notify power domain core that the specified device must
be restored (with its runtime_resume() callback) before first use.

This patch adds the pm_genpd_dev_need_restore() call what brings back
the suspend/resume behaviour for the client devices known from the
previous power domain driver (removed by commit 91cfbd4e - 'ARM:
EXYNOS: Hook up power domains to generic power domain infrastructure').
Client device drivers relay on that suspend/resume behaviour, thus this
patch fixes runtime pm operation for client devices.

      ARM: EXYNOS: read initial state of power domain from hw registers · 76eb5567
      由 Marek Szyprowski 提交于 
      Some bootloaders disable unused power domains to reduce power
consuption. Power domain driver can easily read the actual state from
the hardware registers instead of assuming that their initial state is
always 'on'.

      SH: Convert out[bwl] macros to inline functions · 44033109
      由 Corey Minyard 提交于 
      The macros just called BUG(), but that results in unused variable
warnings all over the place, like in the IPMI driver.  The build
regression emails were annoying me, so here's the fix.  I have
not even compile tested this, but it's rather obvious.
