      clk: imx6: Add SPDIF_GCLK clock in clock tree · 84a87250
      Shengjiu Wang authored
      Correct SPDIF clock setting issue in clock tree, the SPDIF_GCLK is also
      one clock of SPDIF, which is missed before.
      
      We found an issue that imx can't enter low power mode with spdif
      if IMX6x_CLK_SPDIF is used as the core clock of spdif. Because
      spdif driver will register IMX6x_CLK_SPDIF clock to regmap, regmap will do
      clk_prepare in init function, then IMX6x_CLK_SPDIF clock is prepared in probe,
      so its parent clock (PLL clock) is prepared, the prepare operation of
      PLL clock is to enable the clock. But I.MX needs all PLL clock is disabled,
      then it can enter low power mode.
      
      So we can't use IMX6x_CLK_SPDIF as the core clock of spdif, the correct spdif
      core clock is SPDIF_GCLK, which share same gate bit with IMX6x_CLK_SPDIF clock.
      SPDIF_GCLK's parent clock is ipg clock.

      blk: rq_data_dir() should not return a boolean · 10fbd36e
      Linus Torvalds authored
      rq_data_dir() returns either READ or WRITE (0 == READ, 1 == WRITE), not
      a boolean value.
      
      Now, admittedly the "!= 0" doesn't really change the value (0 stays as
      zero, 1 stays as one), but it's not only redundant, it confuses gcc, and
      causes gcc to warn about the construct
      
          switch (rq_data_dir(req)) {
              case READ:
                  ...
              case WRITE:
                  ...
      
      that we have in a few drivers.
      
      Now, the gcc warning is silly and stupid (it seems to warn not about the
      switch value having a different type from the case statements, but about
      _any_ boolean switch value), but in this case the code itself is silly
      and stupid too, so let's just change it, and get rid of warnings like
      this:
      
        drivers/block/hd.c: In function ‘hd_request’:
        drivers/block/hd.c:630:11: warning: switch condition has boolean value [-Wswitch-bool]
           switch (rq_data_dir(req)) {
      
      The odd '!= 0' came in when "cmd_flags" got turned into a "u64" in
      commit 5953316d ("block: make rq->cmd_flags be 64-bit") and is
      presumably because the old code (that just did a logical 'and' with 1)
      would then end up making the type of rq_data_dir() be u64 too.
      
      But if we want to retain the old regular integer type, let's just cast
      the result to 'int' rather than use that rather odd '!= 0'.
