      usb: gadget: s3c-hsotg: fix core reset timeout failure · 2868fea2
      Du, Changbin 提交于
      The timeout values were 1000 and timeout issue occured many times on my
      s3c6410 Soc based board (mostly when booting whith USB cable not
      connected). This patch increase the values to 10000 to guarantee the
      success of reset.
      
      Having set timeout to 10000, I printed the remained timeout values
      which could cause timeout issue before this change (tested several
      times).
      the first timeout value remained:
      	timeout = 8079
      	timeout = 8079
      	timeout = 8078
      	timeout = 8081
      the second timeout value remained:
      	timeout = 7940
      	timeout = 7945
      	timeout = 7940
      	timeout = 7938
      Seeing from above values, I think the value 10000 is big enough.

      usb: gadget: mv_udc: fix boot up hang · 11c37c8b
      Neil Zhang 提交于
      Fix boot up hang when enable udc without otg enabled.
      The root cause is that the clock will be shut down when probe routine is
      finished because of clock gating. When a gadget driver is registered at
      this time, it will call mv_udc_start which in turn will call
      mv_udc_vbus_session. If there is no cable attached at the boot up time,
      the vbus is low, so it will call stop_activity path without clock
      enabled which will cause system hang then.
      Actually, we need't go this path when clock is disabled, what we need to
      do is just jump out.

      build_dtd() can be called when hold a spinlock, but GFP_KERNEL may cause
      dma_pool_alloc() sleep, So we need use GFP_ATOMIC instead of GFP_KERNEL.
      But using GFP_ATOMIC may cause failure when allocating memory, add error
      handler to handle it.

      we aren't ever going to get contiguous block pointers in between calls

      When invalidating the TLBs it is documentated as requiring a post-sync

      drm/i915: reorder edp disabling to fix ivb MacBook Air · 35a38556
      Daniel Vetter 提交于
      eDP is tons of fun. It turns out that at least the new MacBook Air 5,1
      model absolutely doesn't like the new force vdd dance we've introduced
      in
      
      commit 6cb49835
      Author: Daniel Vetter <daniel.vetter@ffwll.ch>
      Date:   Sun May 20 17:14:50 2012 +0200
      
          drm/i915: enable vdd when switching off the eDP panel
      
      But that patch also tried to fix some neat edp sequence issue with the
      force_vdd timings. Closer inspection reveals that we've raised
      force_vdd only to do the aux channel communication dp_sink_dpms. If we
      move the edp_panel_off below that, we don't need any force_vdd for the
      disable sequence, which makes the Air happy.
      
      Unfortunately the reporter of the original bug that the above commit
      fixed is travelling, so we can't test whether this regresses things.
      But my theory is that since we don't check for any power-off ->
      force_vdd-on delays in edp_panel_vdd_on, this was the actual
      root-cause of this failure. With that force_vdd dance completely
      eliminated, I'm hopeful the original bug stays fixed, too.
      
      For reference the old bug, which hopefully doesn't get broken by this:
      
      https://bugzilla.kernel.org/show_bug.cgi?id=43163
      
      In any case, regression fixers win over plain bugfixes, so this needs
      to go in asap.
      
      v2: The crucial pieces seems to be to clear the force_vdd flag
      uncoditionally, too, in edp_panel_off. Looks like this is left behind
      by the firmware somehow.
      
      v3: The Apple firmware seems to switch off the panel on it's own, hence
      we still need to keep force_vdd on, but properly clear it when switching
      the panel off.

      Commit 72121572 ("GPIO: gpio-pxa: fix devicetree functions") added an
      "xlate" function pointer to the irq_domain_ops, but this function is nor
      declared or defined anywhere when CONFIG_OF is disabled, causing the
      build error:
      
        drivers/gpio/gpio-pxa.c:532:11: error: 'irq_domain_xlate_twocell' undeclared here (not in a function)
      
      Extending the DT-only code section to cover the irq_domain_ops and the
      pxa_gpio_dt_ids solves this problem and makes it clearer which code is
      actually used without DT.
