2024-05-19Revert "Merge patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet""Tom Rini1-0/+1
When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay Ethernet"' I failed to notice that b4 noticed it was based on next and so took that as the base commit and merged that part of next to master. This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.

2024-03-17drivers: imx_tmu: Select polling-rate from cpu-thermal devicetree nodeBenjamin Hahn1-2/+4
The polling rate is already specified in some devicetrees, like imx8mp.dtsi for example, but was not selected so far. For the trippoints, the cpu-thermal node is used. Also get the polling rate from this node. Use the default of 5000ms if the polling rate should not be specified in the devicetree. NOTE: The polling rate from the devicetree will be used after this patch. In imx8*.dtsi devicetrees the polling delay is set to 2000ms for example.

2023-09-04thermal: imx_tmu: Increase the polling intervalFabio Estevam1-1/+1
Polling every second to check whether the CPU has cooled down is too frequent. Allow more time for the CPU to cool down by increasing the polling interval to 5 seconds by defaut. This value is used in the absence of the 'polling-delay' devicetree property. Signed-off-by: Fabio Estevam <festevam@denx.de>
2023-09-04thermal: imx_tmu: Fix the temperature unitFabio Estevam1-2/+2
The temperature unit is millidegree Celsius, so divide by 1000 to correctly print the temperature values in Celsius. While at it, also change a typo: "has beyond" to "is beyond". Signed-off-by: Fabio Estevam <festevam@denx.de>
2023-09-04thermal: imx_tmu: Increase the log level for high temperaturesFabio Estevam1-1/+1
dev_info() message is not printed by default. Increase the log level to dev_crit(). This allows the critical messages related to the temperature getting beyong the alert threshold to be displayed. Signed-off-by: Fabio Estevam <festevam@denx.de> Reviewed-by: Tom Rini <trini@konsulko.com>
2023-09-04thermal: imx_tmu: Fix the polling defaultFabio Estevam1-1/+5
When the 'polling-delay' property is not passed via devicetree, pdata->polling_delay keeps at 0. This causes the imx_tmu driver to get stuck inside the busy while() loop when the CPU temperature is above the alert point. Fix this problem by passing a one second polling interval, which provides a proper delay to let the system to cool down and exit the while() loop when the temperature is below the alert point.

The TMU used on iMX93 is IP revision 2.1 which is different with previous revision used on iMX8MQ. So add a new FLAG V4 for this revision to distinguish the operations. Reviewed-by: Peng Fan <peng.fan@nxp.com> Signed-off-by: Ye Li <ye.li@nxp.com> Signed-off-by: Peng Fan <peng.fan@nxp.com>
2023-05-21thermal: imx_tmu: Move architecture code into driverMarek Vasut1-2/+93
Stop polluting the architecture directory with driver specific code, move it into driver where it should be. Split the code slightly so the MX8MM/MX8MN fuse readout and programming and MX8MP fuse readout and programming are in their separate functions, and called in case of matching SoC.

2021-03-01thermal: imx_tmu: enable monitoring and default alert/criticalTim Harvey1-0/+6
Set default critical/alert temperature and enabling monoitoring. Without calling imx_tmu_enable_msite() monitoring will not be enabled and read_temperature will return 0. Additionally without setting alert temperature will cause imx_tmu_get_temp() to spin indefiniately thinking the system needs to cool. This resolves the board spinning endlessly when enabling IMX_TMU in the SPL. Reviewed-by: Fabio Estevam <festevam@gmail.com> Signed-off-by: Tim Harvey <tharvey@gateworks.com>
2021-02-02common: Drop asm/global_data.h from common headerSimon Glass1-0/+1
Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

2020-12-13dm: treewide: Rename 'platdata' variables to just 'plat'Simon Glass1-1/+1
We use 'priv' for private data but often use 'platdata' for platform data. We can't really use 'pdata' since that is ambiguous (it could mean private or platform data). Rename some of the latter variables to end with 'plat' for consistency. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-12-13dm: treewide: Rename auto_alloc_size members to be shorterSimon Glass1-1/+1
This construct is quite long-winded. In earlier days it made some sense since auto-allocation was a strange concept. But with driver model now used pretty universally, we can shorten this to 'auto'. This reduces verbosity and makes it easier to read. Coincidentally it also ensures that every declaration is on one line, thus making dtoc's job easier. Signed-off-by: Simon Glass <sjg@chromium.org>

2020-05-10thermal: imx_tmu: support i.MX8MPPeng Fan1-7/+69
Support i.MX8MP thermal which has two probes and supports temperature range from -40 to 125. Still uses default 1p HW calibration at 25C and loads calibration parameters from fuse. Signed-off-by: Ye Li <ye.li@nxp.com> Signed-off-by: Peng Fan <peng.fan@nxp.com>
2020-05-10thermal: imx_tmu: Check the TEMP range for iMX8MMPeng Fan1-3/+11
On iMX8MM, the V flag in TRISTR register only reflect the state of SNSR value, not the calibrated TEMP value. So checking this flag is not reliable. Per IC suggestion, change to read the TEMP/AVG_TEMP directly and check whether it in valid range 10-125C. Signed-off-by: Ye Li <ye.li@nxp.com> Signed-off-by: Peng Fan <peng.fan@nxp.com>
2020-05-10thermal: imx_tmu: Fix for temperature out of rangePeng Fan1-3/+10
When the temperature is out of sensor's range, the Valid bit won't be set in TRITSR register. So the polling loop won't go out. Change the codes to retry 10 times with 100ms interval for the Valid bit. If the timeout, we give a warning for the invalid data.

2020-05-10thermal: imx_tmu: support TMU arch level initializationPeng Fan1-0/+6

The analog sensors on iMX8MM are new, used for 14LPP process. So the Temperature Sensor Monitoring Unit (TMU) has some change accordingly. We use version 2 in TMU driver to represent the new TMU, so the one driver can service for both i.MX8MQ/M. Signed-off-by: Peng Fan <peng.fan@nxp.com>
