      genirq: replace irq_gc_ack() with {set,clr}_bit variants (fwd) · 659fb32d
      由 Simon Guinot 提交于 
      This fixes a regression introduced by e59347a1 "arm: orion:
Use generic irq chip".

Depending on the device, interrupts acknowledgement is done by setting
or by clearing a dedicated register. Replace irq_gc_ack() with some
{set,clr}_bit variants allows to handle both cases.

Note that this patch affects the following SoCs: Davinci, Samsung and
Orion. Except for this last, the change is minor: irq_gc_ack() is just
renamed into irq_gc_ack_set_bit().

For the Orion SoCs, the edge GPIO interrupts support is currently
broken. irq_gc_ack() try to acknowledge a such interrupt by setting
the corresponding cause register bit. The Orion GPIO device expect the
opposite. To fix this issue, the irq_gc_ack_clr_bit() variant is used.

Tested on Network Space v2.

      ARM: pm: allow suspend finisher to return error codes · 29cb3cd2
      由 Russell King 提交于 
      There are SoCs where attempting to enter a low power state is ignored,
and the CPU continues executing instructions with all state preserved.
It is over-complex at that point to disable the MMU just to call the
resume path.

Instead, allow the suspend finisher to return error codes to abort
suspend in this circumstance, where the cpu_suspend internals will then
unwind the saved state on the stack.  Also omit the tlb flush as no
changes to the page tables will have happened.

      ARM: SAMSUNG: serial: Fix on handling of one clock source for UART · 470f2297
      由 Boojin Kim 提交于 
      This patch fixes the way of comparison for handling of two or more
clock sources for UART.

For example, if just only one clock source is defined even though
there are two clock sources for UART, the serial driver does not
set proper clock up. Of course, it is problem.

So this patch changes the condition of comparison to avoid useless
setup clock and adds a flag 'NO_NEED_CHECK_CLKSRC' which means
selection of source clock is not required.

In addition, since the Exynos4210 has only one clock source for UART
this patch adds the flag into its common_init_uarts().
