+Subject: mmc: core: Cancel delayed work before releasing host
+
+From: Geert Uytterhoeven <geert+renesas@glider.be>
+
+commit 1036f69e251380573e256568cf814506e3fb9988 upstream.
+
+On RZ/Five SMARC EVK, where probing of SDHI is deferred due to probe
+deferral of the vqmmc-supply regulator:

+Subject: mmc: rpmb: fixes pause retune on all RPMB partitions.
+
+From: Jorge Ramirez-Ortiz <jorge@foundries.io>
+
+commit e7794c14fd73e5eb4a3e0ecaa5334d5a17377c50 upstream.
+
+When RPMB was converted to a character device, it added support for
+multiple RPMB partitions (Commit 97548575bef3 ("mmc: block: Convert RPMB to
+a character device").
+
+One of the changes in this commit was transforming the variable target_part
+defined in __mmc_blk_ioctl_cmd into a bitmask. This inadvertently regressed
+the validation check done in mmc_blk_part_switch_pre() and
+mmc_blk_part_switch_post(), so let's fix it.
+
+Fixes: 97548575bef3 ("mmc: block: Convert RPMB to a character device")

+
+Some eMMC devices that do not close the auto clk gate after hw reset will
+cause eMMC initialization to fail. Let's fix this.
