From 721bf080f249ab2adcc4337abe164230bfb8594f Mon Sep 17 00:00:00 2001 From: Chris Morgan Date: Mon, 4 Dec 2023 12:57:16 -0600 Subject: [PATCH] clk: rockchip: rk3568: Mark pclk_usb as critical In the reference manual under "2.8.6 NIU Clock gating reliance" it is stated that pclk_usb_niu has a dependency on hclk_usb_niu. While the manual does not state that this is a bi-directional relationship it was noted that the sdmmc2 failed to operate for me in mmc mode if the pclk_usb was not marked as critical. The parent clock of the hclk_sdmmc2 is hclk_usb.
