Subject: [PATCH v3 2/5] drm/verisilicon: add register-level macros for DCU Lite
Date: Mon, 8 Jun 2026 10:32:34 +0800 [thread overview]
Message-ID: <20260608023237.305036-3-a0987203069@gmail.com> (raw)
In-Reply-To: <20260608023237.305036-1-a0987203069@gmail.com>
Add register-level constants needed by the forthcoming DCUltraLite
hardware ops:
VSDC_DISP_IRQ_VSYNC(n) in vs_crtc_regs.h: bit mask for per-output
VSYNC interrupt bits in DISP_IRQ_STA (0x147C) / DISP_IRQ_EN (0x1480),
which are the IRQ registers used by DCUltraLite in place of the DC8200
TOP_IRQ_ACK / TOP_IRQ_EN registers.
VSDC_FB_CONFIG_ENABLE (bit 0), VSDC_FB_CONFIG_VALID (bit 3) and
VSDC_FB_CONFIG_RESET (bit 4) in vs_primary_plane_regs.h: control bits
in the FB_CONFIG register used by DCUltraLite for framebuffer enable
and per-frame commit handshake.
No behaviour change for existing DC8200 platforms.
