I searched through https://github.com/Xilinx/linux-xlnx/tree/xlnx_rebase_v4.9 for commits that got backported from mainline, and categorized them to see if we want them in an LTS kernel. Most of the contents are specific to xilinx hardware, but some changes are for generic drivers. These commits look like we should have them in the LTS kernel, and they apply cleanly: d86c5a676e5b ("usb: dwc3: gadget: always try to prepare on started_list first") 63b7c83ebea0 ("microblaze: Fix return value from xilinx_timer_init") 7181e5590e5b ("microblaze: Add missing syscalls") 8ee80500ad78 ("microblaze: Add missing release version code v9.6 and v10") 3400606d8ffd ("microblaze: Add new

a5685781dfe9 ("cpufreq: dt: Add zynqmp to the cpufreq dt platdev") 5c8f124893c4 ("mfd: Kconfig: Add missing Kconfig dependency for TPS65086") d15c56cad0e6 ("arm64: dts: xilinx: fix PCI bus dtc

Fix warning variable prev set but not used") 1fd4c45d6cd3 ("usb: gadget: udc-xilinx: remove redundant pointer udc") These look useful, but require a backport to apply: 06aa09081d44 ("gpio: zynq: Provided workaround for GPIO") 6e037fb77086 ("ata: ceva: Correct the AXI bus configuration for SATA ports") f8251f1dfda9 ("i2c: mux: pca954x: Add missing pca9542 definition to chip_desc") 25cd9721c2b1 ("usb: gadget: f_hid: fix: Don't access hidg->req without spinlock held") 51218298a25e ("alarmtimer: Ensure RTC module is not unloaded") These seem harmless but not necessary for stable backports, they could easily get applied if there is a reason for them: 99c494077e2d ("idr: add ida_is_empty") f59d4418c420 ("[media] media: adv7604: fix bindings inconsistency for default-input") 6ab1a322dcaf
