soc: rockchip: Set the proper PWM for rk3288

2019-06-15T09:53:01+00:00

[ Upstream commit bbdc00a7de24cc90315b1775fb74841373fe12f7 ] The rk3288 SoC has two PWM implementations available, the "old" implementation and the "new" one. You can switch between the two of them by flipping a bit in the grf. The "old" implementation is the default at chip power up but isn't the one that's officially supposed to be used. ...and, in fact, the driver that gets selected in Linux using the rk3288 device tree only supports the "new" implementation. Long ago I tried to get a switch to the right IP block landed in the PWM driver (search for "rk3288: Switch to use the proper PWM IP") but that got rejected. In the mean time the grf has grown a full-fledged driver that already sets other random bits like this. That means we can now get the fix landed. For those wondering how things could have possibly worked for the last 4.5 years, folks have mostly been relying on the bootloader to set this bit. ...but occasionally folks have pointed back to my old patch series [1] in downstream kernels.

soc/tegra: pmc: Remove reset sysfs entries on error

2019-06-15T09:53:00+00:00

[ Upstream commit a46b51cd2a57d52d5047e1d48240536243eeab34 ] Commit 5f84bb1a4099 ("soc/tegra: pmc: Add sysfs entries for reset info") added sysfs entries for Tegra reset source and level. However, these sysfs are not removed on error and so if the registering of PMC device is probe deferred, then the next time we attempt to probe the PMC device warnings such as the following will be displayed on boot ... sysfs: cannot create duplicate filename '/devices/platform/7000e400.pmc/reset_reason' Fix this by calling device_remove_file() for each sysfs entry added on failure. Note that we call device_remove_file() unconditionally without checking if the sysfs entry was created in the first place, but this should be OK because kernfs_remove_by_name_ns() will fail silently.

soc: sunxi: Fix missing dependency on REGMAP_MMIO

2019-05-11T05:49:55+00:00

commit a84014e1db35d8e7af09878d0b4bf30804fb17d5 upstream. When enabling ARCH_SUNXI from allnoconfig, SUNXI_SRAM is enabled, but not REGMAP_MMIO, so the kernel fails to link with an undefined reference to __devm_regmap_init_mmio_clk. Select REGMAP_MMIO, as suggested in drivers/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_IRQ To fix the circular dependency, make USB_MUSB_SUNXI select GENERIC_PHY instead of depending on it. This matches the use of GENERIC_PHY by all but two other drivers.

soc: aspeed: Miscellaneous control interfaces

2019-05-06T03:12:13+00:00

The ASPEED BMC SoCs have many knobs and switches that are sometimes design-specific and often defy any approach to unify them under an existing subsystem. Add a driver to translate a devicetree table into sysfs entries to expose bits and fields for manipulation from userspace. This encompasses concepts from scratch registers to boolean conditions to enable or disable host interface features.
