Subject: [PATCH v10 0/7] drm/meson: add support for MIPI DSI Display
Date: Mon, 05 Feb 2024 18:55:27 +0100 [thread overview]
Message-ID: <20240205-amlogic-v6-4-upstream-dsi-ccf-vim3-v10-0-dc06073d5330@linaro.org> (raw)
The Amlogic G12A, G12B & SM1 SoCs embeds a Synopsys DW-MIPI-DSI transceiver (ver 1.21a),
with a custom glue managing the IP resets, clock and data input similar to the DW-HDMI
glue on the same Amlogic SoCs.
This is a follow-up of v5 now the DRM patches are applied, the clk & DT changes
remains for a full DSI support on G12A & SM1 platforms.
The DW-MIPI-DSI transceiver + D-PHY are clocked by the GP0 PLL, and the ENCL encoder + VIU
pixel reader by the VCLK2 clock using the HDMI PLL.
The DW-MIPI-DSI transceiver gets this pixel stream as input clocked with the VCLK2 clock.
An optional "MEAS" clock can be enabled to measure the delay between each vsync feeding the
DW-MIPI-DSI transceiver.
The clock setup has been redesigned to use CCF, a common PLL (GP0) and the VCLK2 clock
path for DSI in preparation of full CCF support and possibly dual display with HDMI.
The change from v5 is that now we use a "VCLK" driver instead of notifier and rely
on CLK_SET_RATE_GATE to ensure the VCLK gate operation are called.

Changes in v10:
- Rename regmap_vclk to meson_clk and add _gate for the gate
- Move COMMON_CLK_MESON_VCLK to following patch
- Remove CLK_SET_RATE_PARENT from g12a_vclk2_sel, keep it only on mipi_dsi_pxclk_sel
- Add more info on commit message to specify how clock setup is designed
- Remove forgotten CLK_IGNORE_UNUSED on g12a_vclk2_input
- Remove useless CLK_SET_RATE_PARENT on g12a_vclk2_div to stop propagatting rate _after_ vclk2_div
- Remove invalid CLK_SET_RATE_GATE on g12a_vclk2 since it's not a divider...
- Drop already applied patches
- move Khadas TS050 changes as an overlay
