ARM: stm32: Fix livetree conversion on STM32MP15xx DHSOM

2024-06-14T11:25:06Z

Unlike fdt_node_check_compatible() which returns 0 if node is compatible, ofnode_device_is_compatible() return true which is non-zero if node is compatible. The intention of the code is to exit from the function in case the node is not compatible with "micrel,ks8851-mll". Add the missing invert into the conditional to reinstate original behavior. This exposes a follow up problem caused by conversion to DM based FMC2 EBI driver, where the FMC2 EBI is not configured when accessed by this code. Probe the KS8851 MAC, which also configures the FMC2 EBI as a dependency, so that the KS8851 MAC CCR register can be accessed over the FMC2 EBI bus and checked for EEPROM present bit.

Revert "Merge patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet""

2024-05-19T14:16:36Z

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. Reported-by: Jonas Karlman Signed-off-by: Tom Rini

net: dwc_eth_qos: Fold board_interface_eth_init into STM32 glue code

2024-04-19T09:30:50Z

Move board_interface_eth_init() into eqos_probe_syscfg_stm32() in STM32 driver glue code. The eqos_probe_syscfg_stm32() parses STM32 specific DT properties of this MAC and configures SYSCFG registers accordingly, there is nothing board specific happening in this function, move it into generic driver code instead. Drop the now unused duplicates from board files. Reviewed-by: Patrice Chotard Signed-off-by: Marek Vasut

ARM: imx: stm32: Test whether ethernet node is enabled before reading MAC EEPROM on DHSOM

2024-04-05T12:37:38Z

Check whether the ethernet interface is enabled at all before reading MAC EEPROM. As a cost saving measure, it can happen that the MAC EEPROM is not populated on SoMs which do not use ethernet. Signed-off-by: Marek Vasut Reviewed-by: Patrice Chotard

ARM: imx: Update DRAM timings with inline ECC on DH i.MX8MP DHCOM SoM

2023-12-16T10:45:07Z

Import DRAM timings generated by the DDR tool 3.31 which introduce assorted tweaks to the DRAM controller settings. Furthermore, enable DBI to improve noise resilience of the DRAM bus by reducing the number of bit changes on the bus. Reduce the DRAM rate to 3600 MTps to remove all remaining correctable errors reported by EDAC . It is not entirely clear why the slightly faster setting does produce sporadic correctable errors, while this one does not, but this could be related to simpler PLL setting at 3600 MTps. Enable inline ECC which is necessary to detect ECC errors and collect statistics by the EDAC driver in Linux. This reduces the DRAM size by 64 MiB for each 512 MiB of DRAM, so for a 4 GiB device the available DRAM size becomes 3.5 GiB and for 2 GiB device the available DRAM size becomes 1.8 GiB.

ARM: imx: Force DRAM regulators into FPWM mode on DH i.MX8MP DHCOM SoM

2023-12-16T10:45:02Z

In case the Buck5 and Buck6 regulators which supply DRAM Vdd1 and Vdd2/Vddq respectively operate in automatic PWM/PFM mode, the DRAM EDAC detects more correctable errors than if the regulators operate in forced PWM only mode. Force DRAM regulators to forced PWM mode only to stop tempting the DRAM. Signed-off-by: Marek Vasut
