Subject: [PATCH v4 0/5] LLCC: Support for Broadcast_AND region
Date: Fri, 29 Mar 2024 14:53:39 -0700 [thread overview]
Message-ID: <20240329-llcc-broadcast-and-v4-0-107c76fd8ceb@quicinc.com> (raw)
This series adds:
1. Device tree register mapping for Broadcast_AND region in SM8450,
SM8550, SM8650.
2. LLCC driver updates to reflect addition of Broadcast_AND regmap.
To support CSR programming, a broadcast interface is used to program all
channels in a single command. Until SM8450 there was only one broadcast
region (Broadcast_OR) used to broadcast write and check for status bit
0. From SM8450 onwards another broadcast region (Broadcast_AND) has been
added which checks for status bit 1.
This series updates the device trees from SM8450 onwards to have a
mapping to this Broadcast_AND region. It also updates the llcc_drv_data
structure with a regmap for Broadcast_AND region and corrects the
broadcast region used to check for status bit 1.
Changes in v4:
- Updated Devicetree patches' commit messages to make problem statement
clearer
- Resolved Konrad's comments on driver code patch
- Updated v3 changelog to include dropped R-b tag
Changes in v3:
- Removed new example in dt-bindings patch and ran 'make
DT_CHECKER_FLAGS=-m dt_binding_check'
- Dropped Krzysztof's R-b tag on dt-bindings patch
- Use of ternary operator in llcc_update_act_ctrl()
- Add comment before initialization of Broadcast_AND regmap in probe
function
- Move DeviceTree patches to the end
Changes in v2:
- Added an additional check in the case old DT files are used for
above mentioned chipsets for backwards compatibility
- Moved addition of if check in llcc_update_act_ctrl() to a separate
"Fixes" patch; not part of this series
