+Subject: [PATCH] clk: rockchip: Add new pll type pll_rk3588_ddr
+
+That PLL type is similar to the other rk3588 pll types but the actual
+rate is twice the configured rate.
+Therefore, the returned calculated rate must be multiplied by two.

+Subject: [PATCH] clk: rockchip: rk3588: drop unused code
+
+All clocks are registered early using CLK_OF_DECLARE(), which marks
+the DT node as processed. For the processed DT node the probe routine
+is never called. Thus this whole code is never executed. This could
+be "fixed" by using CLK_OF_DECLARE_DRIVER, which avoids marking the
+DT node as processed. But then the probe routine would re-register
+all the clocks by calling rk3588_clk_init() again.
