      pll_u can be either controlled by software or hardware and this is
      selected via the OVERRIDE bit in the pll_u base register. In the function
      tegra210_pll_init(), the OVERRIDE bit for pll_u is cleared, which selects
      hardware control of the pll. However, at the same time the pll_u clocks
      are populated in the init_table for tegra210 and so software will try to
      configure the pll_u if it is not already configured and hence, the above
      warning is seen when the pll fails to lock. Remove the pll_u clocks from
      the init_table so that software does not try to configure this pll on
      boot.

      clk: tegra: Fix clock sources for Tegra210 EMC · 4f8d4440
      Jon Hunter 提交于
      The EMC clock sources for Tegra210 currently incorrectly include pll_c2
      and pll_c3. However, both of these should have been pll_mb as shown in
      the TRM. If Tegra210 happens to be configured such that the pll_mb is the
      default clock for the EMC, as configured by the bootloader, then this will
      cause a system hang on boot. This is because the kernel will disable the
      pll_mb when disabling unused clock as it appears to be unused when it is
      not.
      
      Also add the additional pll_p clock source for the EMC.

      Rhyland Klein 提交于
      Most PLL's don't actually have LOCK_ENABLE bits. However, most PLL's
      also had that flag set, which meant that the clk code was trying to
      enable locks, and inadvertantly flipping bits in other fields.
      
      For PLLM, ensure the correct register is used for the misc_register.
      PLL_MISC0 contains the EN_LCKDET bit which should be used for enabling
      the lock, and PLLM_MISC1 shouldn't be used at all.
      
      Lastly, remove some of the settings which would point to the EN_LCKDET
      bits for some PLLs. There is no need to enable the locks, and that is
      done as part of the set_defaults logic already.

      ideapad-laptop: Add Lenovo Yoga 700 to no_hw_rfkill dmi list · 6b31de3e
      Josh Boyer 提交于
      Like the Yoga 900 models the Lenovo Yoga 700 does not have a
      hw rfkill switch, and trying to read the hw rfkill switch through the
      ideapad module causes it to always reported blocking breaking wifi.
      
      This commit adds the Lenovo Yoga 700 to the no_hw_rfkill dmi list, fixing
      the wifi breakage.

      vmstat: Remove BUG_ON from vmstat_update · 587198ba
      Christoph Lameter 提交于
      If we detect that there is nothing to do just set the flag and do not
      check if it was already set before.  Races really do not matter.  If the
      flag is set by any code then the shepherd will start dealing with the
      situation and reenable the vmstat workers when necessary again.
      
      Since commit 0eb77e98 ("vmstat: make vmstat_updater deferrable again
      and shut down on idle") quiet_vmstat might update cpu_stat_off and mark
      a particular cpu to be handled by vmstat_shepherd.  This might trigger a
      VM_BUG_ON in vmstat_update because the work item might have been
      sleeping during the idle period and see the cpu_stat_off updated after
      the wake up.  The VM_BUG_ON is therefore misleading and no more
      appropriate.  Moreover it doesn't really suite any protection from real
      bugs because vmstat_shepherd will simply reschedule the vmstat_work
      anytime it sees a particular cpu set or vmstat_update would do the same
      from the worker context directly.  Even when the two would race the
      result wouldn't be incorrect as the counters update is fully idempotent.
