      ARM: OMAP2/3: Add generic onenand support when connected to GPMC · aa62e90f
      由 Juha Yrjola 提交于 
      Add generic onenand support when connected to GPMC and make the
boards to use it.

The patch has been modified to make it more generic to support all
the boards with GPMC. The patch also remove unused prototype for
omap2_onenand_rephase(void).

Note that board-apollon.c is currently using the MTD_ONENAND_GENERIC
and setting the GPMC timings in the bootloader. Setting the GPMC
timings in the bootloader will not allow supporting frequency
scaling for the onenand source clock.

      OMAP2/3 GPTIMER: allow system tick GPTIMER to be changed in board-*.c files · f248076c
      由 Paul Walmsley 提交于 
      Add a function omap2_gp_clockevent_set_gptimer() for board-*.c files
to use in .init_irq functions to configure the system tick GPTIMER.
Practical choices at this point are GPTIMER1 or GPTIMER12.  Both of
these timers are in the WKUP powerdomain, and so are unaffected by
chip power management.  GPTIMER1 can use sys_clk as a source, for
applications where a high-resolution timer is more important than
power management.  GPTIMER12 has the special property that it has the
secure 32kHz oscillator as its source clock, which may be less prone
to glitches than the off-chip 32kHz oscillator.  But on HS devices, it
may not be available for Linux use.

It appears that most boards are fine with GPTIMER1, but BeagleBoard
should use GPTIMER12 when using a 32KiHz timer source, due to hardware bugs
in revisions B4 and below.  Modify board-omap3beagle.c to use GPTIMER12.

This patch originally used a Kbuild config option to select the GPTIMER,
but was changed to allow this to be specified in board-*.c files, per
Tony's request.

Kalle Vallo <kalle.valo@nokia.com> found a bug in an earlier version of
this patch - thanks Kalle.

Tested on Beagle rev B4 ES2.1, with and without CONFIG_OMAP_32K_TIMER, and
3430SDP.

      OMAP3: clock: Camera module doesn't have IDLEST bit · 9e53dd71
      由 Sergio Aguirre 提交于 
      This patch avoids waiting for the camera module to become ready,
since it doesn't have IDLEST bit.

Based on a earlier hack done by Paul Walmsley on Sep 9 2008 on
linux-omap tree.

      OMAP2xxx clock: fix broken cpu_mask code · 15ca78f7
      由 Paul Walmsley 提交于 
      Commit 8ad8ff65 breaks the OMAP2xxx
cpu_mask code, which causes OMAP2xxx to panic on boot.  Fix by
removing the cpu_mask auto variable and by changing CK_242X
and CK_243X to use RATE_IN_242X/RATE_IN_243X.

      ARM: OMAP2: possible division by 0 · d94a2edd
      由 Roel Kluin 提交于 
      In linus' git tree the functions can be found at:
vi arch/arm/mach-omap2/usb-tusb6010.c +200	- tusb6010_platform_retime()
vi arch/arm/mach-omap2/gpmc.c +94		- gpmc_get_fclk_period()
vi arch/arm/mach-omap2/usb-tusb6010.c +53	- tusb_set_async_mode()
vi arch/arm/mach-omap2/usb-tusb6010.c +111	- tusb_set_sync_mode()

is -ENODEV appropriate when sysclk_ps == 0?

This was found by code analysis, please review.
------------------------------>8-------------8<---------------------------------
gpmc_get_fclk_period() may return 0 when gpmc_l3_clk is not enabled. This is
not checked in tusb6010_platform_retime() nor in tusb_set_async_mode() it
seems. In tusb_set_sync_mode() this may result in a division by zero.
