[PATCH AUTOSEL 6.6 08/19] clk: qcom: Make GCC_8150 depend on QCOM_GDSC

[Sasha Levin]

From: Konrad Dybcio <konrad.dybcio@oss.qualcomm.com>

[ Upstream commit 1474149c4209943b37a2c01b82f07ba39465e5fe ]

Like all other non-ancient Qualcomm clock drivers, QCOM_GDSC is
required, as the GCC driver defines and instantiates a bunch of GDSCs.

Add the missing dependency.

[PATCH AUTOSEL 6.6 17/19] mmc: sdhci-msm: Correctly set the load for the regulator

[Sasha Levin]

From: Yuanjie Yang <quic_yuanjiey@quicinc.com>

[ Upstream commit 20a0c37e44063997391430c4ae09973e9cbc3911 ]

Qualcomm regulator supports two power supply modes: HPM and LPM.
Currently, the sdhci-msm.c driver does not set the load to adjust
the current for eMMC and SD. If the regulator dont't set correct
load in LPM state, it will lead to the inability to properly
initialize eMMC and SD.

Set the correct regulator current for eMMC and SD to ensure that the
device can work normally even when the regulator is in LPM.
