Subject: [PATCH] clk: qcom: gcc-ipq9574: Add BRANCH_HALT_VOTED flag
Date: Thu,  2 May 2024 09:12:47 +0530	[thread overview]
Message-ID: <20240502034247.2621996-1-quic_mdalam@quicinc.com> (raw)

Add BRANCH_HALT_VOTED flag to inform clock framework
don't check for CLK_OFF bit.

CRYPTO_AHB_CLK_ENA and CRYPTO_AXI_CLK_ENA enable bit is
present in other VOTE registers also, like TZ.
If anyone else also enabled this clock, even if we turn
off in GCC_APCS_CLOCK_BRANCH_ENA_VOTE | 0x180B004, it won't
turn off.
