[PATCHv2 0/9] soc: qcom: llcc: Add LLCC support for SM8450 SoC

[Sai Prakash Ranjan]

This patch series adds support for LLCC on SM8450 SoC. It mainly
consists of LLCC driver changes to incorporate newer LLCC HW found
on SM8450 SoC and the corresponding DT bits to enable LLCC.
Based on qcom/for-next branch.

Changes in v2:
 * Fix version assignment to drv_data.

[PATCHv2 2/9] soc: qcom: llcc: Update the logic for version info extraction

[Sai Prakash Ranjan]

LLCC HW version info is made up of major, branch, minor and echo
version bits each of which are 8bits. Several features in newer
LLCC HW are based on the full version rather than just major or
minor versions such as write-subcache enable which is applicable
for versions v2.0.0.0 and later, also upcoming write-subcache
cacheable for SM8450 SoC which is only present in versions v2.1.0.0
and later, so it makes it easier and cleaner to just directly
compare with the full version than adding additional major/branch/
minor/echo version checks. So remove the earlier major version check
and add full version check for those features.

[PATCHv2 3/9] soc: qcom: llcc: Add write-cache cacheable support

[Sai Prakash Ranjan]

Newer SoCs with LLCC IP version 2.1.0.0 and later support write
sub-cache cacheable feature. Use a separate llcc_slice_config member
"write_scid_cacheable_en" to identify this feature and program
LLCC_TRP_SCID_WRSC_CACHEABLE_EN register to enable it.

[PATCHv2 5/9] soc: qcom: llcc: Update register offsets for newer LLCC HW

[Sai Prakash Ranjan]

Newer LLCC HW have different register offsets for several registers,
currently of which LLCC hardware info and status are used to identify
the LLCC version information and other data. So use separate table to
keep track of these register offsets which vary by different LLCC HW
versions and eases any future addition in variations of register offsets
for newer hardware.
