      Revert "RTC: sa1100: remove redundant code of setting alarm" · 57270fcd
      Russell King 提交于
      This reverts commit 42874759.
      
      This wasn't tested as a stand-alone patch, and it has build errors
      without the following patches applied:
      
      drivers/rtc/rtc-sa1100.c: In function 'sa1100_rtc_set_alarm':
      drivers/rtc/rtc-sa1100.c:208: error: 'now' undeclared (first use in this function)
      drivers/rtc/rtc-sa1100.c:208: error: (Each undeclared identifier is reported only once
      drivers/rtc/rtc-sa1100.c:208: error: for each function it appears in.)
      drivers/rtc/rtc-sa1100.c:210: error: incompatible type for argument 3 of 'rtc_next_alarm_time'
      drivers/rtc/rtc-sa1100.c:211: error: 'time' undeclared (first use in this function)
      
      So it too gets reverted to bring us back to a working point.

      Russell King 提交于
      This reverts commit 7cea0065.
      
      The sa1100 cleanups fatally broke the SA1100 RTC driver - the first
      hint that something is wrong are these compiler warnings:

      and the second problem, which is far more severe, are the different
      register layouts, resulting in the wrong registers being read on
      SA11x0 platforms.  This patch adds:
      
      	#define RCNR           0x00    /* RTC Count Register */
      	#define RTAR           0x04    /* RTC Alarm Register */
      	#define RTSR           0x08    /* RTC Status Register */
      	#define RTTR           0x0c    /* RTC Timer Trim Register */
      
      but the SA11x0 registers are:
      
      	#define RTAR            __REG(0x90010000)  /* RTC Alarm Reg. */
      	#define RCNR            __REG(0x90010004)  /* RTC CouNt Reg. */
      	#define RTTR            __REG(0x90010008)  /* RTC Trim Reg. */
      	#define RTSR            __REG(0x90010010)  /* RTC Status Reg. */

      [ARM] pxa: separate definitions from pxa-regs.h and remove it finally · 5bf3df3f
      Eric Miao 提交于
      The remaining registers are separated into:
      
         - <mach/regs-ost.h>
         - <mach/regs-rtc.h>
         - <mach/regs-intc.h>
      
      and then we can remove pxa-regs.h completely. Instead of #include this
      file, let's:
      
      1. include the specific <mach/regs-*.h> with care (if that's absolutely
         necessary)
      
      2. define the registers in the driver, make cleanly defined API to expose
         the register access to external with sufficient reason

      [PATCH] rtc-sa1100 rtc_wklarm.enabled bugfixes · 32b49da4
      David Brownell 提交于
      Some rtc-sa1100 bugfixes:
      
       - The read_alarm() method reports the rtc_wkalrm.enabled field properly.
         This patch is already in the handhelds.org tree.
      
       - And the set_alarm() method now handles that flag correctly, rather than
         making mismatched {en,dis}able_irq_wake() calls, which trigger runtime
         warning messages.  (Those calls are best made in suspend/resume methods.)
      
      Note that while this SA1100/PXA RTC is fully capable of waking those ARM
      processors from sleep states, that mechanism isn't properly supported on
      either processor family, or in this driver.  Some boards have board-specific
      PM glue providing partial workarounds for the weak generic PM support.

      IRQ: Maintain regs pointer globally rather than passing to IRQ handlers · 7d12e780
      David Howells 提交于
      Maintain a per-CPU global "struct pt_regs *" variable which can be used instead
      of passing regs around manually through all ~1800 interrupt handlers in the
      Linux kernel.
      
      The regs pointer is used in few places, but it potentially costs both stack
      space and code to pass it around.  On the FRV arch, removing the regs parameter
      from all the genirq function results in a 20% speed up of the IRQ exit path
      (ie: from leaving timer_interrupt() to leaving do_IRQ()).
      
      Where appropriate, an arch may override the generic storage facility and do
      something different with the variable.  On FRV, for instance, the address is
      maintained in GR28 at all times inside the kernel as part of general exception
      handling.
      
      Having looked over the code, it appears that the parameter may be handed down
      through up to twenty or so layers of functions.  Consider a USB character
      device attached to a USB hub, attached to a USB controller that posts its
      interrupts through a cascaded auxiliary interrupt controller.  A character
      device driver may want to pass regs to the sysrq handler through the input
      layer which adds another few layers of parameter passing.
      
      I've build this code with allyesconfig for x86_64 and i386.  I've runtested the
      main part of the code on FRV and i386, though I can't test most of the drivers.
      I've also done partial conversion for powerpc and MIPS - these at least compile
      with minimal configurations.
      
      This will affect all archs.  Mostly the changes should be relatively easy.
      Take do_IRQ(), store the regs pointer at the beginning, saving the old one:
      
      	struct pt_regs *old_regs = set_irq_regs(regs);
      
      And put the old one back at the end:
      
      	set_irq_regs(old_regs);
      
      Don't pass regs through to generic_handle_irq() or __do_IRQ().
      
      In timer_interrupt(), this sort of change will be necessary:
      
      	-	update_process_times(user_mode(regs));
      	-	profile_tick(CPU_PROFILING, regs);
      	+	update_process_times(user_mode(get_irq_regs()));
      	+	profile_tick(CPU_PROFILING);
      
      I'd like to move update_process_times()'s use of get_irq_regs() into itself,
      except that i386, alone of the archs, uses something other than user_mode().
      
      Some notes on the interrupt handling in the drivers:
      
       (*) input_dev() is now gone entirely.  The regs pointer is no longer stored in
           the input_dev struct.
      
       (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking.  It does
           something different depending on whether it's been supplied with a regs
           pointer or not.
      
       (*) Various IRQ handler function pointers have been moved to type
           irq_handler_t.
