[PATCH v2 0/3] enable power and clock Kconfig conditionally
by Udit Kumar 12 Sep '23

12 Sep '23

This series, updates enabling mutually exclusive power and clock configs for TI SOCs. Sorry to push clock and power changes in one series, managed by two maintainers. But In my quick grep, I am not able to active PR raise from both trees. So copying maintainers of clock and power for review. Change log Changes in v2: - Patch 1 and 2) Added conditional support to enable Kconfig - Patch 3 No change link to v1: https://lore.kernel.org/all/20230911111946.749270-1-u-kumar1@ti.com/ Udit Kumar (3): power: domain: ti: Enable single config for power domain clk: ti: Add support to enable configs conditionally config: j7200: remove not needed power config configs/j7200_evm_r5_defconfig | 1 - drivers/clk/ti/Kconfig | 8 ++++---- drivers/power/domain/Kconfig | 2 +- 3 files changed, 5 insertions(+), 6 deletions(-) -- 2.34.1

To partition a block device the partition type GUIDs are needed but 'gpt read' does not provide these. Add the missing parts. v2: Rename disk_partition_type_uuid() to disk_partition_type_guid(). Use setter for type_guid in allocate_disk_part(). Fix calculation of the size of the partition table descriptor. Use accessor for type_guid field. *** BLURB HERE *** Heinrich Schuchardt (4): part: rename disk_partition_type_uuid() cmd: gpt: use UUID accessor more consistently cmd: gpt: fix calc_parts_list_len() cmd: gpt: fix gpt read cmd/gpt.c | 70 ++++++++++++++++++++++++++++++++----------------- disk/part_efi.c | 2 +- include/part.h | 26 +++++++++++++++--- 3 files changed, 70 insertions(+), 28 deletions(-) -- 2.40.1

[PATCH 0/6] cmd: gpt: GPT manipulation improvements
by Joshua Watt 12 Sep '23

12 Sep '23

Adds several improvements and additions to the gpt command processing, specifically (although not exclusively) for the purpose of supporting "ping-pong" booting when doing A/B boot partitions with u-boot itself. In this mechanism, u-boot must boot up, and then check if the correct boot partition is active, and if not switch the GPT partition table to the other boot partition and reboot to activate the other u-boot. In order to facilitate this, the gpt command needs to be better at preserving entry attributes when manipulating the partition table. It also learns two new commands, one which can swap the order of partitions in the table, and another that lets it change which partitions have the bootable flag. Joshua Watt (6): cmd: gpt: Remove confusing help text cmd: gpt: Add command to set bootable flags cmd: gpt: Add gpt_partition_bootable variable cmd: gpt: Preserve type GUID if enabled cmd: gpt: Preserve bootable flag cmd: gpt: Add command to swap partition order cmd/gpt.c | 160 ++++++++++++++++++++++++++++++++++++++++++++++++++++-- 1 file changed, 154 insertions(+), 6 deletions(-) -- 2.33.0

[PATCH v2 0/7] J721E DTS Sync with Kernel v6.5-rc1
by Neha Malcom Francis 12 Sep '23

12 Sep '23

This series aims to sync kernel.org v6.5-rc1 DTS with that of U-Boot. It also includes cleanups where necessary along with certain changes to ensure boot is unaffected. Same as with other board series that have taken up this effort, cleanup of mcu_ringacc and mcu_udmap are dependent on MCU Ringacc [1] and DMA [2] fixes. This will be taken up after their merge to Linux.

[RESEND PATCH] spi: cadence_qspi: Select flash subnode at runtime
by Udit Kumar 12 Sep '23

12 Sep '23

Currently spi driver gets flash parameter from first subnode. Few boards have more than one flash with different parameters and selection of flash is done by on board switch settings. In such case, uboot needs to be recompiled with updated device tree to align with board switch settings. This patch allows to select flash node at runtime. Boards those are supporting multiple flashes needs to implement cadence_qspi_get_subnode function and return correct flash node.

[PATCH v3 00/13] firmware: scmi: add SCMI base protocol support
by AKASHI Takahiro 12 Sep '23

12 Sep '23

This patch series allows users to access SCMI base protocol provided by SCMI server (platform). It will also be utilized in separate patches in the future to add sanity/validity checks for other protocols. See SCMI specification document v3.2 beta[1] for more details about SCMI base protocol.
