      clk: qcom: Fix PLL rate configurations · 5b6b7490
      Stephen Boyd authored
      Sometimes we need to program PLLs with a fixed rate
      configuration during driver probe. Doing this after we register
      the PLLs with the clock framework causes the common clock
      framework to assume the rate of the PLLs are 0. This causes all
      sorts of problems for rate recalculations because the common
      clock framework caches the rate once at registration time unless
      a flag is set to always recalculate the rates.
      Split the qcom_cc_probe() function into two pieces, map and
      everything else, so that drivers which need to configure some
      PLL rates or otherwise twiddle bits in the clock controller can
      do so before registering clocks. This allows us to properly
      detect the rates of PLLs that are programmed at boot.

      clk: qcom: Fix MN frequency tables, parent map, and jpegd · ff20783f
      Stephen Boyd authored
      Clocks that don't have a pre-divider don't list any pre-divider
      in their frequency tables, but their tables are initialized using
      aggregate initializers. Use tagged initializers so we properly
      assign the m and n values for each frequency. Furthermore, the
      mmcc_pxo_pll8_pll2_pll3 array improperly mapped the second
      element to pll2 instead of pll8, causing the clock driver to
      recalculate the wrong rate for any clocks using this array along
      with a rate that uses pll2. Plus the .num_parents field is 3
      instead of 4 so you can't even switch the parent to pll3. Finally
      I noticed that the jpegd clock improperly indicates that the
      pre-divider width is only 2, when it's actually 4 bits wide.

      clk: qcom: Support bypass RCG configuration · 404c1ff6
      Stephen Boyd authored
      In the case of HDMI clocks, we want to bypass the RCG's ability
      to divide the output clock and pass through the parent HDMI PLL
      rate. Add a simple set of clk_ops to configure the RCG to do
      this. This removes the need to keep adding more frequency entries
      to the tv_src clock whenever we want to support a new rate.

      Add a driver for the global clock controller found on IPQ8064 based
      platforms. This should allow most non-multimedia device drivers to probe
      and control their clocks.

      Pull i2c new drivers from Wolfram Sang:
       "Here is a pull request from i2c hoping for the "new driver" rule.
        Originally, I wanted to send this request during the merge window, but
        code checkers with very recent additions complained, so a few fixups
        were needed.  So, some more time went by and I merged rc1 to get a
        stable base"
      So the "new driver" rule is really about drivers that people absolutely
      need for the kernel to work on new hardware, which is not so much the
      case for i2c.  So I considered not pulling this, but eventually
      Just for FYI: the whole (and only) point of "new drivers" is not that
      new drivers cannot regress things (they can, and they have - by
      triggering badly tested code on machines that never triggered that code
      before), but because they can bring to life machines that otherwise
      wouldn't be useful at all without the drivers.
      So the new driver rule is for essential things that actual consumers
      would care about, ie devices like networking or disk drivers that matter
      to normal people (not server people - they run old kernels anyway, so
      mainlining new drivers is irrelevant for them).

         - Fixes for races in the wait/wakeup logic used in blk-mq from
           Alexander.  No issues have been observed, but it is definitely a
           bit flakey currently.  Alternatively, we may drop the cyclic
           wakeups going forward, but that needs more testing.
         - Some cleanups from Christoph.
         - Fix for an oops in null_blk if queue_mode=1 and softirq completions
           are used.  From me.
         - A fix for a regression caused by the chunk size setting.  It
           inadvertently used max_hw_sectors instead of max_sectors, which is
           incorrect, and causes hangs on btrfs multi-disk setups (where hw
           sectors apparently isn't set).  From me.
         - Removal of WQ_POWER_EFFICIENT in the kblockd creation.  This was a
           recent addition as well, but it actually breaks blk-mq which relies
           on strict scheduling.  If the workqueue power_efficient mode is
           turned on, this breaks blk-mq.  From Matias.

      If connector->dpms is left untouched, it defaults

      As a result, drm_helper_connector_dpms will exit when
      it will be asked to set the state to DRM_MODE_DPMS_ON,
      because it is already set.
      That issue prevented displays from turning on at boot.

      unicore32: Remove ARCH_HAS_CPUFREQ config option · d670878e
      Stephen Boyd authored
      This config exists entirely to hide the cpufreq menu from the
      kernel configuration unless a platform has selected it. Nothing
      is actually built if this config is 'Y' and it just leads to more
      patches that add a select under a platform Kconfig so that some
      other CPUfreq option can be chosen. Let's remove the option so
      that we can always enable CPUfreq drivers on unicore32 platforms.
