 Subject: [PATCH] drm/rockchip: cdn-dp: fix reference leak when
 pm_runtime_get_sync fails
 The PM reference count is not expected to be incremented on
 return in cdn_dp_clk_enable.
 However, pm_runtime_get_sync will increment the PM reference
 count even failed. Forgetting to putting operation will result
 in a reference leak here.
 Replace it with pm_runtime_resume_and_get to keep usage
 counter balanced.

 Subject: [PATCH] drm/rockchip: lvds: fix reference leak when
 pm_runtime_get_sync fails
 The PM reference count is not expected to be incremented on
 return in functions rk3288_lvds_poweron and px30_lvds_poweron.
 However, pm_runtime_get_sync will increment the PM reference
 count even failed. Forgetting to putting operation will result
 in a reference leak here.
 Replace it with pm_runtime_resume_and_get to keep usage
 counter balanced.

 Devfreq framework supports 2 modes for monitoring devices.
 Use delayed timer as default instead of deferrable timer

 Subject: [PATCH] drm/panfrost: Add governor data with pre-defined thresholds
 The simple_ondemand devfreq governor uses two thresholds to decide about
 the frequency change: upthreshold, downdifferential. These two tunable
 change the behavior of the governor decision, e.g. how fast to increase
 the frequency or how rapidly limit the frequency. This patch adds needed
 governor data with thresholds values gathered experimentally in different
 workloads.

 When a fault is handled it will unblock the GPU which will continue
 executing its shader and might fault almost immediately on a different
 page. If we clear interrupts after handling the fault we might miss new
 faults, so clear them before.

 Subject: [PATCH] arm64: dts: rockchip: add gpu powerdomain, gpu opp-table and
 cooling cell
 Note: since the regulator that supplies the GPU usually also supplies
 other SoC components, we have to make sure voltage is never lower then
 1050 mV.

 Subject: [PATCH] media: rkvdec: add variants support
 rkvdec IP has different versions which among others differ in
 the supported decoding formats.
 This adds an variant implementation in order support other
 than the currently supported RK3399 version.
 Note: Since matching of supported codecs is index-based the
 available codec options have been reordered here: from
 supported by all versions to not commonly supported. This seems
 the better soultion than duplicatiing code for every newly added IP.
