soc: qcom: socinfo: rename PM2250 to PM4125

2024-03-26T22:16:34Z

[ Upstream commit 5155e48128826d0c5999dc9f47aa746df54da448 ] It seems, the only actual mentions of PM2250 can be found are related to the Qualcomm RB1 platform. However even RB1 schematics use PM4125 as a PMIC name. Rename PM2250 to PM4125 to follow the documentation. Fixes: 082f9bc60f33 ("soc: qcom: spmi-pmic: add more PMIC SUBTYPE IDs") Fixes: 112d96fd2927 ("soc: qcom: socinfo: Add some PMICs") Acked-by: Konrad Dybcio Signed-off-by: Dmitry Baryshkov Link: https://lore.kernel.org/r/20240128-pm2250-pm4125-rename-v2-1-d51987e9f83a@linaro.org Signed-off-by: Bjorn Andersson Signed-off-by: Sasha Levin

RISC-V SoC drivers for v6.8 There's only one set of changes here, the addition of "Auto Update" support for PolarFire SoC. Auto Update is one of the ways that the FPGA bitstream can be updated, and the only one suitable for use from Linux as it does not immediately initiate a reboot when started. The driver was not accepted in the FPGA manager subsystem as the update only occurs after a reboot and makes no use of the FPGA manager framework.

soc: fsl: cpm1: qmc: Introduce functions to change timeslots at runtime

2023-12-12T09:29:20Z

Introduce qmc_chan_{get,set}_ts_info() function to allow timeslots modification at runtime. The modification is provided using qmc_chan_set_ts_info() and will be applied on next qmc_chan_start(). qmc_chan_set_ts_info() must be called with the channel rx and/or tx stopped.

QMC child devices support is needed to avoid orphan DT nodes that use a simple DT phandle to reference a QMC channel. Allow to instantiate child devices and also extend the API to get the qmc_chan using a child device.

soc: fsl: cpm1: qmc: Extend the API to provide Rx status

2023-12-12T09:29:20Z

In HDLC mode, some status flags related to the data read transfer can be set by the hardware and need to be known by a QMC consumer for further analysis. Extend the API in order to provide these transfer status flags at the read complete() call. In TRANSPARENT mode, these flags have no meaning. Keep only one read complete() API and update the consumers working in transparent mode. In this case, the newly introduced flags parameter is simply unused.

memory: tegra: Add SID override programming for MC clients

2023-11-21T09:09:28Z

For some devices the bootloader/firmware may set up the device in bypass. Memory clients like display needs kernel to program SID after resume because bootloader/firmware programs the SID of display device to bypass. In order to make sure that kernel IOMMU mappings for these devices work after resume, add SID override programming support for all memory clients on memory controller resume.
