Pull MIPS updates from Paul Burton: "Main MIPS changes: - boot_mem_map is removed, providing a nice cleanup made possible by the recent removal of bootmem. - Some fixes to atomics, in general providing compiler barriers for smp_mb__{before,after}_atomic plus fixes specific to Loongson CPUs or MIPS32 systems using cmpxchg64(). - Conversion to the new generic VDSO infrastructure courtesy of Vincenzo Frascino. - Removal of undefined behavior in set_io_port_base(), fixing the behavior of some MIPS kernel configurations when built with recent clang versions. - Initial MIPS32 huge page support, functional on at least Ingenic SoCs. - pte_special() is now supported for some configurations, allowing among other things generic fast GUP to be used. - Miscellaneous fixes & cleanups. And platform specific changes: - Major improvements to Ingenic SoC support from Paul Cercueil, mostly enabled by the inclusion of the new TCU (timer-counter unit) drivers he's spent a very patient year or so working on. Plus some fixes for X1000 SoCs from Zhou Yanjie. - Netgear R6200 v1 systems are now supported by the bcm47xx platform. - DT updates for BMIPS, Lantiq & Microsemi Ocelot systems" * tag 'mips_5.4' of git://git.kernel.org/pub/scm/linux/kernel/git/mips/linux: (89 commits) MIPS: Detect bad _PFN_SHIFT values MIPS: Disable pte_special() for MIPS32 with RiXi MIPS: ralink: deactivate PCI support for SOC_MT7621 mips: compat: vdso: Use legacy syscalls as fallback MIPS: Drop Loongson _CACHE_* definitions MIPS: tlbex: Remove cpu_has_local_ebase MIPS: tlbex: Simplify r3k check MIPS: Select R3k-style TLB in Kconfig MIPS: PCI: refactor ioc3 special handling mips: remove ioremap_cachable mips/atomic: Fix smp_mb__{before,after}_atomic() mips/atomic: Fix loongson_llsc_mb() wreckage mips/atomic: Fix cmpxchg64 barriers MIPS: Octeon: remove duplicated include from dma-octeon.c firmware: bcm47xx_nvram: Allow COMPILE_TEST firmware: bcm47xx_nvram: Correct size_t printf format MIPS: Treat Loongson Extensions as ASEs MIPS: Remove dev_err() usage after platform_get_irq() MIPS: dts: mscc: describe the PTP ready interrupt MIPS: dts: mscc: describe the PTP register range ...

power: supply: cpcap-charger: Enable vbus boost voltage

2019-09-02T21:08:07Z

We are currently not enabling VBUS boost for cpcap when in host mode. This means the VBUS is fed at the battery voltage level, which can cause flakeyness enumerating devices. Looks like the boost control for VBUS is CPCAP_BIT_VBUS_SWITCH that we must enable in the charger for nice 4.92 V VBUS output. And looks like we must not use the STBY pin enabling but must instead use manual VBUS control in phy-cpcap-usb. We want to do this in cpcap_charger_vbus_work() and also set a flag for feeding_vbus to avoid races between USB detection and charger detection, and disable charging if feeding_vbus is set.

power: supply: sc27xx: Add POWER_SUPPLY_PROP_CALIBRATE attribute

2019-09-02T21:00:20Z

Add the 'POWER_SUPPLY_PROP_CALIBRATE' attribute to allow chareger manager to calibrate the battery capacity. Signed-off-by: Yuanjiang Yu Signed-off-by: Baolin Wang Signed-off-by: Sebastian Reichel

power: supply: sc27xx: Optimize the battery capacity calibration

2019-09-02T20:59:50Z

This patch factors out the capacity calibration into one single function to calibrate the battery capacity, and adding more abnormal cases to calibrate the capacity when the OCV value is not matchable with current capacity. Moreover we also allow to calibrate the capacity when charger magager tries to get current capacity to make sure we give a correct capacity for userspace.

power: supply: sc27xx: Make sure the alarm capacity is larger than 0

2019-09-02T20:55:24Z

We must make sure the alarm capacity is larger than 0, to help to calibrate the low battery capacity. Signed-off-by: Yuanjiang Yu Signed-off-by: Baolin Wang Signed-off-by: Sebastian Reichel

power: supply: sc27xx: Fix the the accuracy issue of coulomb calculation

2019-09-02T20:49:49Z

The Spreadtrum fuel gauge will multiply by 2 for counting the coulomb counter to improve the accuracy, which means the value saved in fuel gauge is: coulomb counter * 2 * 1000ma_adc. Thus fix the conversion formular to improve the accuracy of calculating the battery capacity. Signed-off-by: Yuanjiang Yu Signed-off-by: Baolin Wang Signed-off-by: Sebastian Reichel

power: supply: sc27xx: Fix conditon to enable the FGU interrupt

2019-09-02T20:47:09Z
