Subject: [PATCH RESEND 06/17] clk: spacemit: k3: parent eDP/DP pixel clock to the PHY PLL
Date: Sat, 25 Jul 2026 00:51:15 -0400 [thread overview]
Message-ID: <20260725-k3-display-v1-6-6de34d80e86c@gmail.com> (raw)
In-Reply-To: <20260725-k3-display-v1-0-6de34d80e86c@gmail.com>
From: Cody Kang <codykang.hk@gmail.com>
The APMU eDP/DP pixel-clock muxes were parented to a placeholder, because
their real parents (the DP PHY PLLs) did not exist as clocks yet. They do
now, so point each mux at its PLL and let the pixel clock reach the
controller through the clock framework.
