This series is based on v5.8-rc1
change since v16:
- Introduce hierarchical scpsys device node to show the dependency between each
power domain.
And could be more clearly to group subsys clocks into power domain sub node.
change since v15:
- remove unneeded error log in [PATCH 06/11]
changes
Added support for HK10-C1 and HK10-C2 board variants based on IPQ8074 SoC.
Both these variants support dual QCN9000 PCIe cards that uses MHI communication
protocol over PCIe. In addition, HK10-C1 support on-chip radio.
Both these variants slightly differ in clock configuation for ethernet.

This patch changes the read I/O to the HPB read I/O.
If the logical address of the read I/O belongs to active sub-region, the
HPB driver modifies the read I/O command to HPB read. It modifies the UPIU
command of UFS instead of modifying the existing SCSI command.
In the HPB version 1.0, the maxim
For the bus protection operations, some subsys clocks need to be enabled
before releasing the protection, and vice versa.
But those subsys clocks could only be controlled once its corresponding
power domain is turned on first.
In this patch, we add the subsys clock control into its relevant steps.
For some power domains like vpu_core on MT8183 whose sram need to
do clock and internal isolation while power on/off sram.
We add a cap "MTK_SCPD_SRAM_ISO" to judge if we need to do
the extra sram isolation control or not.
