This patch series adds support for the Qualcomm RPMH power domain driver, responsible for managing power domains on Qualcomm SoCs. The driver is ported from the Linux kernel and adapted for U-Boot to enable proper power domain control on SA8775P platform.
Signed-off-by: Aswin Murugan <[email protected]> --- Changes in v6: - Added the change in drivers/power/domain/power-domain-uclass.c to give warning when power-domain driver is missing - Added the change log 'In qcom-rpmhpd driver, the un-supported power domains are handled with warning in rpmhpd_power_on() & rpmhpd_power_on()' - In drivers/power/domain/qcom-rpmhpd.c, the 'ret' variable in rpmhpd_probe() is initialized with 0 - Link to v5: https://lore.kernel.org/u-boot/[email protected]/ Changes in v5: - As part of "qcom_rpmhpd" driver removal change did in v4, the rpmh_write() in drivers/power/domain/qcom-rpmhpd.c should be passed with pd->dev as first argument to align with it. - Added (ulong) casting in rpmhpd_match_table to address the warning. Changes in v4: - Added all soc entries in power domain linux driver to drivers/power/domain/qcom-rpmhpd.c and stubbed it - Removed "qcom_rpmhpd" driver & unused members of struct rpmhpd in drivers/power/domain/qcom-rpmhpd.c - Moved the "soc: qcom: cmd-db" change before the "power-domain" change - Link to v3: https://lore.kernel.org/u-boot/[email protected]/ Changes in v3: - Removed OF_LIVE_SA8775P config in arch/arm/mach-snapdragon/Kconfig & configs/qcs9100_defconfig, since there is no SA8775p specific fixups are done - Link to v2: https://lore.kernel.org/u-boot/[email protected]/ Changes in v2: - Added ARCH_SNAPDRAGON dependency to QCOM_POWER_DOMAIN in drivers/power/domain/Kconfig - In drivers/power/domain/qcom-rpmhpd.c, the un-supported power domains are handled with warning - Power domain fixups have been removed since they are now managed by drivers/power/domain/qcom-rpmhpd.c - Link to v1: https://lore.kernel.org/u-boot/[email protected]/ --- Aswin Murugan (5): soc: qcom: cmd-db: Add cmd_db_read_slave_id() & cmd_db_read_aux_data() functions power-domain: Add QCOM RPMH Power Domain Driver Support power-domain: Add warning when power-domain driver is missing mach-snapdragon: fixup power-domains configs: qcom: Add QCOM_POWER_DOMAIN config arch/arm/mach-snapdragon/of_fixup.c | 31 --- configs/qcom_defconfig | 1 + drivers/power/domain/Kconfig | 8 + drivers/power/domain/Makefile | 1 + drivers/power/domain/power-domain-uclass.c | 8 + drivers/power/domain/qcom-rpmhpd.c | 278 +++++++++++++++++++++ drivers/soc/qcom/cmd-db.c | 45 ++++ include/soc/qcom/cmd-db.h | 2 + 8 files changed, 343 insertions(+), 31 deletions(-) create mode 100644 drivers/power/domain/qcom-rpmhpd.c -- 2.34.1
