power: supply: qcom_battmgr: remove bogus do_div()

2023-03-01T18:41:18+00:00

The argument to do_div() is a 32-bit integer, and it was read from a 32-bit register so there is no point in doing a 64-bit division on it. On 32-bit arm, do_div() causes a compile-time warning here: include/asm-generic/div64.h:238:22: error: passing argument 1 of '__div64_32' from incompatible pointer type [-Werror=incompatible-pointer-types] 238 | __rem = __div64_32(&(n), __base); \ | ^~~~ | | | unsigned int * drivers/power/supply/qcom_battmgr.c:1130:4: note: in expansion of macro 'do_div' 1130 | do_div(battmgr->status.percent, 100); Signed-off-by: Arnd Bergmann Reviewed-by: Geert Uytterhoeven Acked-by: Sebastian Reichel Reviewed-by: Konrad Dybcio Signed-off-by: Linus Torvalds

Pull ARM SoC driver updates from Arnd Bergmann: "As usual, there are lots of minor driver changes across SoC platforms from NXP, Amlogic, AMD Zynq, Mediatek, Qualcomm, Apple and Samsung. These usually add support for additional chip variations in existing drivers, but also add features or bugfixes. The SCMI firmware subsystem gains a unified raw userspace interface through debugfs, which can be used for validation purposes. Newly added drivers include: - New power management drivers for StarFive JH7110, Allwinner D1 and Renesas RZ/V2M - A driver for Qualcomm battery and power supply status - A SoC device driver for identifying Nuvoton WPCM450 chips - A regulator coupler driver for Mediatek MT81xxv" * tag 'soc-drivers-6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (165 commits) power: supply: Introduce Qualcomm PMIC GLINK power supply soc: apple: rtkit: Do not copy the reg state structure to the stack soc: sunxi: SUN20I_PPU should depend on PM memory: renesas-rpc-if: Remove redundant division of dummy soc: qcom: socinfo: Add IDs for IPQ5332 and its variant dt-bindings: arm: qcom,ids: Add IDs for IPQ5332 and its variant dt-bindings: power: qcom,rpmpd: add RPMH_REGULATOR_LEVEL_LOW_SVS_L1 firmware: qcom_scm: Move qcom_scm.h to include/linux/firmware/qcom/ MAINTAINERS: Update qcom CPR maintainer entry dt-bindings: firmware: document Qualcomm SM8550 SCM dt-bindings: firmware: qcom,scm: add qcom,scm-sa8775p compatible soc: qcom: socinfo: Add Soc IDs for IPQ8064 and variants dt-bindings: arm: qcom,ids: Add Soc IDs for IPQ8064 and variants soc: qcom: socinfo: Add support for new field in revision 17 soc: qcom: smd-rpm: Add IPQ9574 compatible soc: qcom: pmic_glink: remove redundant calculation of svid soc: qcom: stats: Populate all subsystem debugfs files dt-bindings: soc: qcom,rpmh-rsc: Update to allow for generic nodes soc: qcom: pmic_glink: add CONFIG_NET/CONFIG_OF dependencies soc: qcom: pmic_glink: Introduce altmode support ...

power: reset: odroid-go-ultra: fix I2C dependency

power: reset: add Odroid Go Ultra poweroff driver

2023-02-14T22:02:39+00:00

The Hardkernel Odroid Go Ultra poweroff scheme requires requesting a poweroff to its two PMICs in order, this represents the poweroff scheme needed to complete a clean poweroff of the system. This implement this scheme by implementing a self registering driver to permit using probe defer until both pmics are finally probed. Signed-off-by: Neil Armstrong Signed-off-by: Sebastian Reichel

power: supply: Introduce Qualcomm PMIC GLINK power supply

2023-02-13T21:45:37+00:00

The PMIC GLINK service, running on a coprocessor of modern Qualcomm platforms, deals with battery charging and fuel gauging, as well as reporting status of AC and wireless power supplies. As this is just one of the functionalities provided by the PMIC GLINK service, this power supply driver is implemented as an auxilirary bus driver, spawned by the main "pmic glink" driver when the PMIC GLINK service is detected.
