[PATCH v9 21/23] drm: rockchip: Add VOP2 driver

Sascha Hauer
2022-03-28T15:12:36Z

From: Andy Yan <andy.yan@rock-chips.com>

The VOP2 unit is found on Rockchip SoCs beginning with rk3566/rk3568.
It replaces the VOP unit found in the older Rockchip SoCs.

This driver has been derived from the downstream Rockchip Kernel and
heavily modified:

- All nonstandard DRM properties have been removed
- dropped struct vop2_plane_state and pass around less data between
functions
- Dropped all DRM_FORMAT_* not known on upstream
- rework register access to get rid of excessively used macros
- Drop all waiting for framesyncs

The driver is tested with HDMI and MIPI-DSI display on a RK3568-EVB
board. Overlay support is tested with the modetest utility. AFBC support
on the cluster windows is tested with weston-simple-dmabuf-egl on
weston using the (yet to be upstreamed) panfrost driver support.

Notes:
Changes since v6:
- Drop device tree parsing during runtime
- Fix typo in Kconfig help text

Changes since v5:
- consistently use u8/u16/u32 rather than uint8_t/uint16_t/uint32_t
- Use spin_lock rather than spin_lock_irqsave
- replace printk with drm_dbg
- break some overlong lines

Changes since v4:
- Avoid stack frame overflow by not allocating big array on the stack

Changes since v3:
- Sort includes
- fix typos
- Drop spinlock
- Use regmap_set_bits()/regmap_clear_bits()
- simplify vop2_scale_factor()
- simplify vop2_afbc_transform_offset()
