      [ARM] pass reboot command line to arch_reset() · be093beb
      Russell King 提交于
      OMAP wishes to pass state to the boot loader upon reboot in order to
      instruct it whether to wait for USB-based reflashing or not.  There is
      already a facility to do this via the reboot() syscall, except we ignore
      the string passed to machine_restart().
      
      This patch fixes things to pass this string to arch_reset().  This means
      that we keep the reboot mode limited to telling the kernel _how_ to
      perform the reboot which should be independent of what we request the
      boot loader to do.

      [ARM] make page_to_dma() highmem aware · 58edb515
      Nicolas Pitre 提交于
      If a machine class has a custom __virt_to_bus() implementation then it
      must provide a __arch_page_to_dma() implementation as well which is
      _not_ based on page_address() to support highmem.
      
      This patch fixes existing __arch_page_to_dma() and provide a default
      implementation otherwise.  The default implementation for highmem is
      based on __pfn_to_bus() which is defined only when no custom
      __virt_to_bus() is provided by the machine class.
      
      That leaves only ebsa110 and footbridge which cannot support highmem
      until they provide their own __arch_page_to_dma() implementation.
      But highmem support on those legacy platforms with limited memory is
      certainly not a priority.

      [ARM] omap: add support for bypassing DPLLs · c0bf3132
      Russell King 提交于
      This roughly corresponds with OMAP commits: 7d06c48, 3241b19,
      88b5d9b, 18a5500, 9c909ac, 5c6497b, 8b1f0bd, 2ac1da8.
      
      For both OMAP2 and OMAP3, we note the reference and bypass clocks in
      the DPLL data structure.  Whenever we modify the DPLL rate, we first
      ensure that both the reference and bypass clocks are enabled.  Then,
      we decide whether to use the reference and DPLL, or the bypass clock
      if the desired rate is identical to the bypass rate, and program the
      DPLL appropriately.  Finally, we update the clock's parent, and then
      disable the unused clocks.
      
      This keeps the parents correctly balanced, and more importantly ensures
      that the bypass clock is running whenever we reprogram the DPLL.  This
      is especially important because the procedure for reprogramming the DPLL
      involves switching to the bypass clock.
