[v11,0/5] Add support for RZ/G2L VSPD

  The RZ/G2L VSPD provides a single VSPD instance. It has the following
sub modules MAU, CTU, RPF, DPR, LUT, BRS, WPF and LIF.

The VSPD block on RZ/G2L does not have a version register, so added a
new compatible string "renesas,r9a07g044-vsp2" with a data pointer containing
the info structure. Also the reset line is shared with the DU module.

This patch series is tested on RZ/G1N, RZ/G2M and RZ/G2L boards.

v10->v11:
 * Added poll for reset status in order to avoid lock-up on R-Car Gen2
 * with vsp register access after deassert.

v9->v10
 * Moved {deassert,assert} calls to vsp1_pm_runtime_{resume,suspend}

V8->v9
 * Added Rb tag from Geert for patch#3
 * Replaced break with return info in case a Model match is found and
   removed additional check for non-match case.
 * Used generic check for matching SoCs with LBA feature.
 * Replaced the code comments RZ/G2L {SoC's,SoC} with RZ/G2L SoCs.
v7->v8:
 * Split the patch for adding s/w version, feature bit and RZ/G2L support
 * Added feature bit VSP1_HAS_NON_ZERO_LBA to device_info
 * Added .soc for RZ/G2L
 * Replaced the compatible "renesas,rzg2l-vsp2" -> "renesas,r9a07g044-vsp2"
 * Updated Clock-names to false for non RZ/G2L SoC's on binding doc
 * Added Rb tag from Laurent for bindings
v6->v7:
 * Added Rb tag from Kieran for patch#3
 * Added a quirk to handle LIF0 buffer attribute related
   changes for V3M and G2L.
 * Removed the macro for VSP HW version
v5->v6:
 * Rebased to media_staging and updated commit header
 * Removed LCDC reference clock description from bindings
 * Changed the clock name from du.0->aclk from bindings
 * Added Rb tag from Laurent for reset patch
 * Added forward declaration for struct reset_control
 * Updated vsp1_device_get() with changes suggested by Laurent
 * Updated error message for reset_control_get form ctrl->control.
 * Removed the extra tab from rzg2l_vsp2_device_info
 * Changed the function vsp1_lookup->vsp1_lookup_info and
   all info match related code moved here.
 * Add VI6_IP_VERSION_VSP and VI6_IP_VERSION_VSP_SW macros to
   distinguish HW & SW IP_VSP_Version.
 * Used 0x80 for RZG2L VSPD model and SoC identification
 * Updated Switch() for LIF0 buffer attribute handling.
v4->v5:
 * Fixed typo VI6_IP_VERSION_MODEL_MASK->VI6_IP_VERSION_MASK
 * To be consistent with other SoC's, introduced VI6_IP_VERSION_SOC_G2L
   for SoC identification for RZ/G2L SoC's.
v3->v4:
 * Restored error check for pm_runtime_resume_and_get and calls
   assert() in case of failure.
 * Added Rb tag from Geert
 * Add switch() for LIF0 buffer attribute handling for RZ/G2L and V3M SoC's
v2->v3:
 * Added Rb tags from Krzysztof and Philipp
 * If reset_control_deassert() failed, return ret directly.
 * Fixed version comparison in vsp1_lookup()
v1->v2:
 * Used reference counted reset handle to perform deassert/assert
 * Changed the compatible from vsp2-rzg2l->rzg2l-vsp2
 * Added standalone device info for rzg2l-vsp2.
 * Added vsp1_lookup helper function.
 * Updated comments for LIF0 buffer attribute register
 * Used last ID for rzg2l-vsp2.
RFC->v1:
 * Added reset support as separate patch
 * Moved rstc just after the bus_master field in struct vsp1_device
 * Used data pointer containing info structure to retrieve version information
 * Updated commit description
 * Changed compatible from vsp2-r9a07g044->vsp2-rzg2l
 * Defined the clocks
 * Clock max Items is based on SoC Compatible string

Hi Mauro, Laurent and Kieran,

Gentle ping,

Are there any issues with this patch series for acceptance?

Please let me know. If needed, I can send new patch series/follow-up patches for the suggestions.

Cheers,
Biju
