[PATCH v3 5/6] media: hantro: add support for Rockchip RK3066

2021-06-14T21:34:33Z

RK3066's VPU IP block is the predecessor from what RK3288 has.
The hardware differences are:
- supports decoding frame sizes up to 1920x1088 only
- doesn't have the 'G1_REG_SOFT_RESET' register
(requires another .reset callback for hantro_codec_ops,
since writing this register will result in non-working
IP block)
- has one ACLK/HCLK per vdpu/vepu
- ACLKs can be clocked up to 300 MHz only
- no MMU
(no changes required: CMA will be transparently used)

Add a new RK3066 variant which reflect this differences. This variant
can be used for RK3188 as well.

Changes in v3:
- rename rk3066_clk_names -> rk3066_vpu_clk_names
- collect Reviewed-tag

Changes in v2:
- fixed wrong index in clk array for vepu clock in rk3066_vpu_hw_init
- added comment, why this variant can't be splitted in g1/h1 variants
