clk: samsung: gs101: Fix missing USI7_USI DIV clock in peric0_clk_regs

2026-06-19T11:42:27+00:00

[ Upstream commit 78ee734b36284d82454e87a92094fdb926985b47 ] In the peric0_clk_regs array, the divider register offset for USI6 was accidentally listed twice, while the divider for USI7 was omitted. Missing this DIV register causes the USI7 clock divider setting to be lost and reset to its hardware default value during a suspend/resume cycle. Replace the duplicated USI6 DIV entry with the correct USI7 DIV register.

clk: qcom: x1e80100-dispcc: Stop disp_cc_mdss_mdp_clk_src from getting parked

2026-06-19T11:42:26+00:00

[ Upstream commit bc27dbefae6ed11376d991a2921eff806ffef67c ] Parking disp_cc_mdss_mdp_clk_src at 19.2MHz causing the EFI GOP framebuffer to stop functioning. The EFI GOP framebuffer should keep working until the msm display driver loads, to help with boot debugging and to ensure display output when the msm module is not in the initramfs. Switch disp_cc_mdss_mdp_clk_src over to clk_rcg2_shared_no_init_park_ops to keep the EFI GOP working after binding the x1e80100-dispcc driver.

clk: visconti: pll: initialize clk_init_data to zero

2026-05-23T11:04:46+00:00

[ Upstream commit 1603cbb64173a0e9fa7500f2a686f4aa011c58b9 ] Sashiko reported the following: > The struct clk_init_data init is declared on the stack without being > fully zero-initialized. While fields like name, flags, parent_names, > num_parents, and ops are explicitly assigned, the parent_data and > parent_hws fields are left containing stack garbage. clk_core_populate_parent_map() currently prefers the parent names over the parent data and hws, so this isn't a problem at the moment. If that ordering ever changed in the future, then this could lead to some unexpected crashes. Let's just go ahead and make sure that the struct clk_init_data is initialized to zero as a good practice.

clk: qcom: gcc-x1e80100: Keep GCC USB QTB clock always ON

[ Upstream commit 05566ebcc0cd170bd4f50c907ee3ed8e106251e3 ] In Hamoa, SMMU invalidation requires the GCC_AGGRE_USB_NOC_AXI_CLK to be on for the USB QTB to be functional. This is currently explicitly enabled by the DWC3 glue driver, so an invalidation happening while the USB controller is suspended will fault. Solve this by voting for the GCC MMU USB QTB clock.
