[PATCH 5.18 0709/1095] clk: qcom: ipq8074: set BRANCH_HALT_DELAY flag for UBI clocks

From: Greg Kroah-Hartman
Date: Mon Aug 15 2022 - 17:53:58 EST


From: Robert Marko <robimarko@xxxxxxxxx>

[ Upstream commit 2bd357e698207e2e65db03007e4be65bf9d6a7b3 ]

Currently, attempting to enable the UBI clocks will cause the stuck at
off warning to be printed and clk_enable will fail.

[ 14.936694] gcc_ubi1_ahb_clk status stuck at 'off'

Downstream 5.4 QCA kernel has fixed this by seting the BRANCH_HALT_DELAY
flag on UBI clocks, so lets do the same.
