+* Handle interrupts better
+
+Currently the interrupt handling uses an unusual design employing a kfifo to
+transfer irq status to irq thread. This was done as a work around for dropped
+interrupts seen with IRQF_ONESHOT based handling.
+
+This needs further investigation and fixing properly, with the aid of
+C&M and StarFive engineers.
+
+* appropriate error handling:
+allocation failure, mutex acquire failure etc.
+
+* remove all unused struct fields
+
+* change struct fields to 'bool' type or bitfield when appropriate
+Likely good candidates are fields named '*_enable' , '*_on'
+
+* handle vdi_allocate_dma_memory failure , each function has to clean after itself
+
+* make sure that 'u32', 's32' etc. are only used when reading/writing hw
+and change s32 to u32 when s32 is not required
+
+* power management handling - add (runtime_)suspen/resume cb where the clock is enabled
+
+* fix checkpatch issues (mostly fixes , only left to fix MACRO_ARG_REUSE, LONG_LINE)
+
+* revise logic of wave5_vpu_(dec/enc)_register_framebuffer
+
+* check if the  normal kernel endianness/__swab32 routines are sufficient. (instead of the ones
+implemented in the driver
+
+* Extended Codec Controls for encoder.
+
+implement extended codec control for HEVC/H264 encoder.
