pmdomain: sunxi: Move Kconfig option to the pmdomain subsystemThe Kconfig option belongs closer to the corresponding implementation,hence let's move it from the soc subsystem to the pmdomain subsystem.Cc: Chen-Yu Tsai Cc: Jernej Skrabec Cc: Samuel Holland Cc: Acked-by: Jernej Skrabec Signed-off-by: Ulf Hansson List of files: /linux-6.15/drivers/soc/sunxi/Kconfig

Single device driversshould only depend on PM, not select it.Having SUN20I_PPU depend on PM removes a kconfig warning:WARNING: unmet direct dependencies detected for PM Depends on [n]: !MMU [=y] Selected by [y]: - SUN20I_PPU [=y] && (ARCH_SUNXI || COMPILE_TEST [=y])Fixes: 0ad2185dcb5e ("soc: sunxi: select CONFIG_PM")Signed-off-by: Randy Dunlap Cc: Chen-Yu Tsai Cc: Jernej Skrabec Cc: Samuel Holland Cc: linux-arm-kernel@lists.infradead.orgCc: linux-sunxi@lists.linux.devCc: Arnd Bergmann Cc: Geert Uytterhoeven Signed-off-by: Arnd Bergmann List of files: /linux-6.15/drivers/soc/sunxi/Kconfig

soc: sunxi: select CONFIG_PMSelecting CONFIG_PM_GENERIC_DOMAINS without CONFIG_PM leads to abuild failure:WARNING: unmet direct dependencies detected for PM_GENERIC_DOMAINS Depends on [n]: PM [=n] Selected by [y]: - SUN20I_PPU [=y] && (ARCH_SUNXI [=n] || COMPILE_TEST [=y])drivers/base/power/domain_governor.c: In function 'default_suspend_ok':drivers/base/power/domain_governor.c:85:24: error: 'struct dev_pm_info' has no member named 'ignore_children' 85 | if (!dev->power.ignore_children) | ^drivers/base/power/domain.c: In function 'genpd_queue_power_off_work':drivers/base/power/domain.c:657:20: error: 'pm_wq' undeclared (first use in this function) 657 | queue_work(pm_wq, &genpd->power_off_work); | ^~~~~Unfortunately platforms are inconsistent between using 'select PM'and 'depends on PM' here. CONFIG_PM is a user-visible symbol, soin principle we should be using 'depends on', but on the other handusing 'select' here is more common among drivers/soc. Go with themajority for now, as this has a smaller risk of introducing circulardependencies. We may need to clean this up for consistency later.Fixes: 0e30ca5ab0a8 ("soc: sunxi: Add Allwinner D1 PPU driver")Acked-by: Jernej Skrabec Signed-off-by: Arnd Bergmann List of files: /linux-6.15/drivers/soc/sunxi/Kconfig

0e30ca5a - soc: sunxi: Add Allwinner D1 PPU driver

Thu, 26 Jan 2023 06:34:18 +0000

soc: sunxi: Add Allwinner D1 PPU driverThe PPU contains a series of identical MMIO register ranges, one foreach power domain. Each range contains control/status bits for a clockgate, reset line, output gates, and a power switch. (The clock and resetare separate from, and in addition to, the bits in the CCU.) It alsocontains a hardware power sequence engine to control the other bits.Acked-by: Jernej Skrabec Signed-off-by: Samuel Holland Link: https://lore.kernel.org/r/20230126063419.15971-3-samuel@sholland.orgSigned-off-by: Jernej Skrabec List of files: /linux-6.15/drivers/soc/sunxi/Kconfig

soc: sunxi: mbus: Only build the driver on ARM/ARM64This driver exists as a workaround for old devicetrees which are missinginterconnects properties, so it is only useful for those specificplatforms, which all happen to be ARM or ARM64.This solves the issue that the driver fails to build on RISC-V, wherePHYS_OFFSET is not defined.Signed-off-by: Samuel Holland Reviewed-by: Jernej Skrabec Signed-off-by: Jernej Skrabec Link: https://lore.kernel.org/r/20220702032520.22129-1-samuel@sholland.org List of files: /linux-6.15/drivers/soc/sunxi/Kconfig

b4bdc4fb - soc: sunxi: Deal with the MBUS DMA offsets in a central place

Fri, 06 Nov 2020 14:52:30 +0000

soc: sunxi: Deal with the MBUS DMA offsets in a central placeSo far most of the drivers with the MBUS quirks had to duplicate thecode to deal with DT compatibility and enforcing the DMA offsets.Let's move for a more maintainable solution by putting everything in anotifier that would take care of setting up the DMA offsets for all theMBUS devices.Suggested-by: Robin Murphy Signed-off-by: Maxime Ripard Reviewed-by: Chen-Yu Tsai Reviewed-by: Christoph Hellwig Acked-by: Daniel Vetter List of files: /linux-6.15/drivers/soc/sunxi/Kconfig

a84014e1 - soc: sunxi: Fix missing dependency on REGMAP_MMIO

Tue, 30 Apr 2019 14:59:37 +0000

soc: sunxi: Fix missing dependency on REGMAP_MMIOWhen enabling ARCH_SUNXI from allnoconfig, SUNXI_SRAM is enabled, butnot REGMAP_MMIO, so the kernel fails to link with an undefined referenceto __devm_regmap_init_mmio_clk. Select REGMAP_MMIO, as suggested indrivers/base/regmap/Kconfig.This creates the following dependency loop: drivers/of/Kconfig:68: symbol OF_IRQ depends on IRQ_DOMAIN kernel/irq/Kconfig:63: symbol IRQ_DOMAIN is selected by REGMAP drivers/base/regmap/Kconfig:7: symbol REGMAP default is visible depending on REGMAP_MMIO drivers/base/regmap/Kconfig:39: symbol REGMAP_MMIO is selected by SUNXI_SRAM drivers/soc/sunxi/Kconfig:4: symbol SUNXI_SRAM is selected by USB_MUSB_SUNXI drivers/usb/musb/Kconfig:63: symbol USB_MUSB_SUNXI depends on GENERIC_PHY drivers/phy/Kconfig:7: symbol GENERIC_PHY is selected by PHY_BCM_NS_USB3 drivers/phy/broadcom/Kconfig:29: symbol PHY_BCM_NS_USB3 depends on MDIO_BUS drivers/net/phy/Kconfig:12: symbol MDIO_BUS default is visible depending on PHYLIB drivers/net/phy/Kconfig:181: symbol PHYLIB is selected by ARC_EMAC_CORE drivers/net/ethernet/arc/Kconfig:18: symbol ARC_EMAC_CORE is selected by ARC_EMAC drivers/net/ethernet/arc/Kconfig:24: symbol ARC_EMAC depends on OF_IRQTo fix the circular dependency, make USB_MUSB_SUNXI select GENERIC_PHYinstead of depending on it.

4af34b57 - drivers: soc: sunxi: Introduce SoC driver to map SRAMs

Mon, 01 Jun 2015 09:04:26 +0000

drivers: soc: sunxi: Introduce SoC driver to map SRAMsThe Allwinner SoCs have a handful of SRAM that can be either mapped to beaccessible by devices or the CPU.That mapping is controlled by an SRAM controller, and that mapping mightnot be set by the bootloader, for example if the device wasn't used at all,or if we're using solutions like the U-Boot's Falcon Boot.We could also imagine changing this at runtime for example to change themapping of these SRAMs to use them for suspend/resume or runtime memoryrate change, if that ever happens.These use cases require some API in the kernel to control that mapping,exported through a drivers/soc driver.This driver also implement a debugfs file that shows the SRAM found in thesystem, the current mapping and the SRAM that have been claimed by somedrivers in the kernel.Signed-off-by: Maxime Ripard Acked-by: Arnd Bergmann Acked-by: Hans de Goede Tested-by: Hans de Goede Signed-off-by: Arnd Bergmann List of files: /linux-6.15/drivers/soc/sunxi/Kconfig
