mfd: dln2: Add cell for initializing DLN2 ADC

2021-11-18T18:17:17Z

commit 313c84b5ae4104e48c661d5d706f9f4c425fd50f upstream. This patch extends the DLN2 driver; adding cell for adc_dln2 module. The original patch[1] fell through the cracks when the driver was added so ADC has never actually been usable. That patch did not have ACPI support which was added in v5.9, so the oldest supported version this current patch can be backported to is 5.10.

mfd: altera-sysmgr: Fix a mistake caused by resource_size conversion

2021-11-18T18:17:09Z

[ Upstream commit fae2570d629cdd72f0611d015fc4ba705ae5422b ] The resource_size defines that: res->end - res->start + 1; The origin original code is: sysmgr_config.max_register = res->end - res->start - 3; So, the correct fix is that: sysmgr_config.max_register = resource_size(res) - 4; Fixes: d12edf9661a4 ("mfd: altera-sysmgr: Use resource_size function on resource object") Signed-off-by: Kai Song Signed-off-by: Lee Jones Link: https://lore.kernel.org/r/20211006141926.6120-1-songkai01@inspur.com Signed-off-by: Sasha Levin

mfd: sprd: Add SPI device ID table

2021-11-18T18:17:09Z

[ Upstream commit c5c7f0677107052060037583b9c8c15d818afb04 ] Currently autoloading for SPI devices does not use the DT ID table, it uses SPI modalises. Supporting OF modalises is going to be difficult if not impractical, an attempt was made but has been reverted, so ensure that module autoloading works for this driver by adding a SPI device ID table.

Pull gpio updates from Bartosz Golaszewski: "We mostly have various improvements and refactoring all over the place but also some interesting new features - like the virtio GPIO driver that allows guest VMs to use host's GPIOs.

Summary: - new driver: gpio-virtio allowing a guest VM running linux to access GPIO lines provided by the host - split the GPIO driver out of the rockchip pin control driver - add support for a new model to gpio-aspeed-sgpio, refactor the driver and use generic device property interfaces, improve property sanitization - add ACPI support to gpio-tegra186 - improve the code setting the line names to support multiple GPIO banks per device - constify a bunch of OF functions in the core GPIO code and make the declaration for one of the core OF functions we use consistent within its header - use software nodes in intel_quark_i2c_gpio - add support for the gpio-line-names property in gpio-mt7621 - use the standard GPIO function for setting the GPIO names in gpio-brcmstb - fix a bunch of leaks and other bugs in gpio-mpc8xxx - use generic pm callbacks in gpio-ml-ioh - improve resource management and PM handling in gpio-mlxbf2 - modernize and improve the gpio-dwapb driver - coding style improvements in gpio-rcar - documentation fixes and improvements - update the MAINTAINERS entry for gpio-zynq - minor tweaks in several drivers" * tag 'gpio-updates-for-v5.15' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux: (35 commits) gpio: mpc8xxx: Use 'devm_gpiochip_add_data()' to simplify the code and avoid a leak gpio: mpc8xxx: Fix a potential double iounmap call in 'mpc8xxx_probe()' gpio: mpc8xxx: Fix a resources leak in the error handling path of 'mpc8xxx_probe()' gpio: viperboard: remove platform_set_drvdata() call in probe gpio: virtio: Add missing mailings lists in MAINTAINERS entry gpio: virtio: Fix sparse warnings gpio: remove the obsolete MX35 3DS BOARD MC9S08DZ60 GPIO functions gpio: max730x: Use the right include gpio: Add virtio-gpio driver gpio: mlxbf2: Use DEFINE_RES_MEM_NAMED() helper macro gpio: mlxbf2: Use devm_platform_ioremap_resource() gpio: mlxbf2: Drop wrong use of ACPI_PTR() gpio: mlxbf2: Convert to device PM ops gpio: dwapb: Get rid of legacy platform data mfd: intel_quark_i2c_gpio: Convert GPIO to use software nodes gpio: dwapb: Read GPIO base from gpio-base property gpio: dwapb: Unify ACPI enumeration checks in get_irq() and configure_irqs() gpiolib: Deduplicate forward declaration in the consumer.h header MAINTAINERS: update gpio-zynq.yaml reference gpio: tegra186: Add ACPI support ...
