      ARM: OMAP4: Add minimal support for omap4 · 44169075
      Santosh Shilimkar 提交于
      This patch adds the support for OMAP4. The platform and machine specific
      headers and sources updated for OMAP4430 SDP platform.
      
      OMAP4430 is Texas Instrument's SOC based on ARM Cortex-A9 SMP architecture.
      It's a dual core SOC with GIC used for interrupt handling and SCU for cache
      coherency.

      ARM: OMAP2/3: Serial: Remove arch_initcall dependency · 2aa57be2
      Vikram Pandita 提交于
      Move platform_device_register() for serial device to
      omap_serial_init()
      
      There is no need to have arch_initcall() dependency in serial
      as already board files call the function omap_serial_init()

      OMAP: UART: Add sysfs interface for adjusting UART sleep timeout · ba87a9be
      Jouni Hogander 提交于
      This patch makes it possible to change uart sleep timeout. New sysfs
      entry is added (/sys/devices/platform/serial8250.<uart>/sleep_timeout)
      Writing zero will disable the timeout feature and prevent UART clocks
      from being disabled.
      
      Also default timeout is increased to 5 second to make serial console
      more usable.
      
      Original patch was written by Tero Kristo.

      OMAP3: PM: UART: disable clocks when idle and off-mode support · 4af4016c
      Kevin Hilman 提交于
      This patch allows the UART clocks to be disabled when the OMAP UARTs
      are inactive, thus permitting the chip to hit retention in idle.
      After the expiration of an activity timer, each UART is allowed to
      disable its clocks so the system can enter retention.  The activity
      timer is (re)activated on any UART interrupt, UART wake event or any
      IO pad wakeup.  The actual disable of the UART clocks is done in the
      'prepare_idle' hook called from the OMAP idle loop.
      
      While the activity timer is active, the smart-idle mode of the UART is
      also disabled.  This is due to a "feature" of the UART module that
      after a UART wakeup, the smart-idle mode may be entered before the
      UART has communicated the interrupt, or upon TX, an idle mode may be
      entered before the TX FIFOs are emptied.
      
      Upon suspend, the 'prepare_suspend' hook cancels any pending activity
      timers and allows the clocks to be disabled immediately.
      
      In addition, upon disabling clocks the UART state is saved in case
      of an off-mode transition while clocks are off.
      
      Special thanks to Tero Kristo for the initial ideas and first versions
      of UART idle support, and to Jouni Hogander for extra testing and
      bugfixes.
      
      Tested on OMAP3 (Beagle, RX51, SDP, EVM) and OMAP2 (n810)

      [ARM] 3145/1: OMAP 3a/5: Add support for omap24xx · 1dbae815
      Tony Lindgren 提交于
      Patch from Tony Lindgren
      
      This patch adds support for omap24xx series of processors.
      The files live in arch/arm/mach-omap2, and share common
      files with omap15xx and omap16xx processors in
      arch/arm/plat-omap.
      
      Omap24xx support was originally added for 2.6.9 by TI.
      This code was then improved and integrated to share common
      code with omap15xx and omap16xx processors by various
      omap developers, such as Paul Mundt, Juha Yrjola, Imre Deak,
      Tony Lindgren, Richard Woodruff, Nishant Menon, Komal Shah
      et al.
