Subject: [PATCH v5 0/3] Driver for Core Power Reduction v3, v4 and Hardened
Date: Thu, 21 Jan 2021 20:40:48 +0100 [thread overview]
Message-ID: <20210121194051.484209-1-angelogioacchino.delregno@somainline.org> (raw)
**
** NOTE: To "view the full picture", please look at the following
** patch series:
** https://patchwork.kernel.org/project/linux-arm-msm/list/?series=413355
** This is a subset of that series.
**
Changes in v5:
- Fixed getting OPP table when not yet installed by the caller
of power domain attachment
Changes in v4:
- Huge patch series has been split for better reviewability,
as suggested by Bjorn
Changes in v3:
- Fixed YAML doc issues
- Removed unused variables and redundant if branch
Changes in v2:
- Implemented dynamic Memory Accelerator corners support, needed
by MSM8998
- Added MSM8998 Silver/Gold parameters
This commit introduces a new driver, based on the one for cpr v1,
to enable support for the newer Qualcomm Core Power Reduction
hardware, known downstream as CPR3, CPR4 and CPRh, and support
for MSM8998 and SDM630 CPU power reduction.
In these new versions of the hardware, support for various new
features was introduced, including voltage reduction for the GPU,
security hardening and a new way of controlling CPU DVFS,
consisting in internal communication between microcontrollers,
specifically the CPR-Hardened and the Operating State Manager.
The CPR v3, v4 and CPRh are present in a broad range of SoCs,
from the mid-range to the high end ones including, but not limited
to, MSM8953/8996/8998, SDM630/636/660/845.
Tested on the following smartphones:
- Sony Xperia XA2 (SDM630)
- Sony Xperia XA2 Ultra (SDM630)
- Sony Xperia 10 (SDM630)
- Sony Xperia XZ Premium (MSM8998)
- F(x)Tec Pro 1 (MSM8998)
