[PATCH v5 14/24] drm/msm/dsi/phy: Toggle back buffer resync after preparing PLL

2025-04-30 Thread Krzysztof Kozlowski
According to Hardware Programming Guide for DSI PHY, the retime buffer resync should be done after PLL clock users (byte_clk and intf_byte_clk) are enabled. Downstream also does it as part of configuring the PLL. Driver was only turning of the resync FIFO buffer, but never bringing it on again.
