      drm/msm: Delete unnecessary checks before drm_gem_object_unreference_unlocked() · e73a8569
      Markus Elfring 提交于
      The drm_gem_object_unreference_unlocked() function tests whether
      its argument is NULL and then returns immediately.
      Thus the test around the calls is not needed.
      
      This issue was detected by using the Coccinelle software.

      drm/msm: Call pm_runtime_enable/disable for newly created devices · cd792726
      Archit Taneja 提交于
      With the new device hierarchy for MDP5, we need to enable runtime PM
      for both the toplevel MDSS device and the MDP5 device itself. Enable
      runtime PM for the new devices.
      
      Since MDP4 and MDP5 now have different places where runtime PM is
      enabled, remove the previous pm_runtime_enable/disable calls, and
      squash them in the respective kms drivers.
      
      The new device hierarchy (as expressed in the DT bindings) has the GDSC
      tied only to the MDSS wrapper device. This GDSC needs to be enabled for
      accessing any register in the MDSS sub-blocks. Once every driver is
      runtime adapted, the GDSC will be enabled when any sub-block device
      calls runtime_get because of the parent-child relationship with MDSS.
      
      Until then, we call pm_runtime_get_sync() once for the MDSS device to
      ensure the GDSC is never disabled. This will be removed once all the
      drivers are runtime PM adapted.
      
      The error handling paths become a bit tricky when we call these runtime
      PM funcs. There doesn't seem to be any helper that checks if runtime PM
      is enabled already. Add bool variables in mdp4_kms/mdp5_kms structs to
      check if the driver had managed to call pm_runtime_enable before bailing
      out.

      drm/msm: Get irq number within kms driver itself · a2b3a557
      Archit Taneja 提交于
      The driver gets the irq number using platform_get_irq on the main kms
      platform device. This works fine since both MDP4 and MDP5 currently
      have a flat device hierarchy. The platform device tied with the
      drm_device points to the MDP DT node in both cases.
      
      This won't work when MDP5 supports a tree-like hierarchy. In this
      case, the platform device tied to the top level drm_device is the
      MDSS DT node, and the irq we need for KMS is the one generated by
      MDP5, not MDSS.
      
      Get the irq number from the MDP4/5 kms driver itself. Each driver
      can later provide the irq number based on what device hierarchy it
      uses.
      
      While we're at it, call drm_irq_install only when we have a valid KMS
      driver.

      drm/msm/mdp4: Clean up some MDP4 clocks · db9e44fb
      Archit Taneja 提交于
      Fix some issues with MDP4 clocks:
      
      - mdp4_dtv_encoder tries to get "src_clk", which is a RCG(TV_SRC) in
        MSM8960 and APQ8064. This isn't something the driver should access or
        configure. Instead of this, configure the "mdp_clk" (MDP_TV_CLK), a
        branch clock in MMCC that has the TV_SRC as its parent. Setting
        rate/enabling the "mdp_clk" will eventually configure "src_clk", which
        is what we want.
      - Rename "mdp_clk" to "tv_clk" because that's slightly less confusing.
      - Rename "mdp_axi_clk" to "bus_clk" because that's what we do elsewhere
        too.

      drm/msm: Centralize connector registration/unregistration · 8208ed93
      Archit Taneja 提交于
      Move the drm_connector registration from the encoder(HDMI/DSI etc) drivers
      to the msm platform driver. This will simplify the task of ensuring that
      the connectors are registered only after the drm_device itself is
      registered.
      
      The connectors' destroy ops are made to use kzalloc instead of
      devm_kzalloc to ensure that that the connectors can be successfully
      unregistered when the msm driver module is removed. The memory for the
      connectors is unallocated when drm_mode_config_cleanup() is called
      during either during an error or during driver remove.

      drm/msm/mdp4: Don't manage DSI PLL regulators in MDP driver · ed19075b
      Archit Taneja 提交于
      The MDP4 driver tries to request and set voltages for regulators required
      by the DSI PLLs.
      
      Firstly, the MDP4 driver shouldn't manage the DSI regulators, this should
      be handled in the DSI driver. Secondly, it shouldn't try to set a fixed
      voltage for regulators. Voltage constraints should be specified on the
      regulator via DT and managed by the regulator core.
      
      Remove all the DSI PLL regulator related code from the MDP4 driver. It's
      managed in the DSI driver for MSM8960/APQ8064 already.

      drm/msm: rename hdmi symbols · fcda50c8
      Arnd Bergmann 提交于
      Global symbols in the kernel should be prefixed by the name
      of the subsystem and/or driver to avoid conflicts when all
      code is built-in.
      
      In this case, function names like 'hdmi_register' or 'hdmi_set_mode'
      are way too generic for an MSM specific DRM driver, so I'm renaming
      them all to msm_hdmi_* here.
      
      I also rename a lot of the 'static' symbols along with the global
      names for consistency, even though those are relatively harmless;
      they might only be slightly confusing when they show up in
      backtraces.
