[U-Boot] [PATCH 00/15] socfpga: sequencer.c cleanups
by Marek Vasut 03 Aug '15

03 Aug '15

This entire series focuses solely on cleaning up the drivers/ddr/altera/sequencer.c file. After this series, this one file is totally checkpatch clean and does not pull in any weird qts-generated macros ; all that is wrapped in the board file. This micro-series applies on top of my previous middle-series [1]. This series is available via git at [2].

[U-Boot] [PATCH] arm: dts: socfpga: Fix SPI aliases
by Marek Vasut 03 Aug '15

03 Aug '15

The SPI aliases are completely wrong. First, they point to non-existing /spi@.* nodes instead of the correct /soc/spi@.* nodes. Second, the use ad-hoc string instead of a handle. Furthermore, they are copied multiple times in each board DTS. So fix it such that we move these into socfpga.dtsi and make them use the usual handles.

fdt_addr_t is a physical address. It can be either 64-bit or 32-bit, depending on the architecture. It should be phys_addr_t instead of u64 or u32. Similarly, fdt_size_t is changed to phys_size_t.

[U-Boot] [PATCH 00/55] dm: exynos: Driver model improvements leading to spring support
by Simon Glass 03 Aug '15

03 Aug '15

This series adds a number of fixes and improvements to driver model as well as two new uclasses (video bridges and I2c muxes). The series is aimed at adding support for spring (HP 11 Chromebook). Since it is very similar to other ARM Chromebooks, some effory is made to use common code rather than duplicating functionality. In fact spring uses the same code as several other boards, just with a different device tree and a few configuration changes. Audio works correctly on pit, pi, spring and snow with this series. A bug in the I2C driver broken this recently. The exynos implementation still has a few rough areas - e.g. some hard-coded GPIOs and the old-style SPL. Also it does not yet support CPU frequency scaling and power management. Spring has some oddities and they are hard to handle with U-Boot's old way of doing drivers. With driver model these can be implemented cleanly and this sort of problem was the original motivation for my interest in driver model. This series is available at u-boot-dm in branch spring-working. It is based on the previous set of driver model changes in branch clk-working.

[U-Boot] [PATCH 1/3] sunxi: usb-phy: Never power off the usb ports
by Hans de Goede 03 Aug '15

03 Aug '15

USB devices are not really designed to get the power bounced off and on at them. Esp. USB powered harddisks do not like this. Currently we power off the USB ports both on a "usb reset" and when booting the kernel, causing the usb-power to bounce off and then back on again. This patch removes the powering off calls, fixing the undesirable power bouncing. Note this requires some special handling for the OTG port: 1) We must skip the external vbus check if we've already enabled our own vbus to avoid false positives 2) If on an usb reset we no longer detect that the id-pin is grounded, turn off vbus as that means an external vbus may be present now Signed-off-by: Hans de Goede <hdegoede(a)redhat.com> --- Changes in v2: -Skip the vbus detect for the otg port if we've already turned the power on, otherwise we get a false positive for having an external vbus and the otg port is not usable after an usb reset --- arch/arm/cpu/armv7/sunxi/usb_phy.c | 7 +++++++ arch/arm/include/asm/arch-sunxi/usb_phy.h | 1 + drivers/usb/host/ehci-sunxi.c | 1 - drivers/usb/host/ohci-sunxi.c | 1 - drivers/usb/musb-new/sunxi.c | 28 ++++++++++++++++------------ 5 files changed, 24 insertions(+), 14 deletions(-) diff --git a/arch/arm/cpu/armv7/sunxi/usb_phy.c b/arch/arm/cpu/armv7/sunxi/usb_phy.c index 4d63a74..b7ca5d4 100644 --- a/arch/arm/cpu/armv7/sunxi/usb_phy.c +++ b/arch/arm/cpu/armv7/sunxi/usb_phy.c @@ -232,6 +232,13 @@ void sunxi_usb_phy_power_off(int index) gpio_set_value(phy->gpio_vbus, 0); } +int sunxi_usb_phy_power_is_on(int index) +{ + struct sunxi_usb_phy *phy = &sunxi_usb_phy[index]; + + return phy->power_on_count > 0; +} + int sunxi_usb_phy_vbus_detect(int index) { struct sunxi_usb_phy *phy = &sunxi_usb_phy[index]; diff --git a/arch/arm/include/asm/arch-sunxi/usb_phy.h b/arch/arm/include/asm/arch-sunxi/usb_phy.h index cef6c98..6a14cad 100644 --- a/arch/arm/include/asm/arch-sunxi/usb_phy.h +++ b/arch/arm/include/asm/arch-sunxi/usb_phy.h @@ -16,6 +16,7 @@ void sunxi_usb_phy_init(int index); void sunxi_usb_phy_exit(int index); void sunxi_usb_phy_power_on(int index); void sunxi_usb_phy_power_off(int index); +int sunxi_usb_phy_power_is_on(int index); int sunxi_usb_phy_vbus_detect(int index); int sunxi_usb_phy_id_detect(int index); void sunxi_usb_phy_enable_squelch_detect(int index, int enable); diff --git a/drivers/usb/host/ehci-sunxi.c b/drivers/usb/host/ehci-sunxi.c index 34130f8..38d5f92 100644 --- a/drivers/usb/host/ehci-sunxi.c +++ b/drivers/usb/host/ehci-sunxi.c @@ -67,7 +67,6 @@ static int ehci_usb_remove(struct udevice *dev) if (ret) return ret; - sunxi_usb_phy_power_off(priv->phy_index); sunxi_usb_phy_exit(priv->phy_index); #ifdef CONFIG_SUNXI_GEN_SUN6I diff --git a/drivers/usb/host/ohci-sunxi.c b/drivers/usb/host/ohci-sunxi.c index e33a8f7..6079272 100644 --- a/drivers/usb/host/ohci-sunxi.c +++ b/drivers/usb/host/ohci-sunxi.c @@ -69,7 +69,6 @@ static int ohci_usb_remove(struct udevice *dev) if (ret) return ret; - sunxi_usb_phy_power_off(priv->phy_index); sunxi_usb_phy_exit(priv->phy_index); #ifdef CONFIG_SUNXI_GEN_SUN6I diff --git a/drivers/usb/musb-new/sunxi.c b/drivers/usb/musb-new/sunxi.c index 16a264a..a146c08 100644 --- a/drivers/usb/musb-new/sunxi.c +++ b/drivers/usb/musb-new/sunxi.c @@ -196,8 +196,6 @@ static bool enabled = false; static int sunxi_musb_enable(struct musb *musb) { - int ret; - pr_debug("%s():\n", __func__); musb_ep_select(musb->mregs, 0); @@ -210,17 +208,26 @@ static int sunxi_musb_enable(struct musb *musb) musb_writeb(musb->mregs, USBC_REG_o_VEND0, 0); if (is_host_enabled(musb)) { - ret = sunxi_usb_phy_vbus_detect(0); - if (ret == 1) { - printf("A charger is plugged into the OTG: "); - return -ENODEV; + int id = sunxi_usb_phy_id_detect(0); + + if (id == 1 && sunxi_usb_phy_power_is_on(0)) + sunxi_usb_phy_power_off(0); + + if (!sunxi_usb_phy_power_is_on(0)) { + int vbus = sunxi_usb_phy_vbus_detect(0); + if (vbus == 1) { + printf("A charger is plugged into the OTG: "); + return -ENODEV; + } } - ret = sunxi_usb_phy_id_detect(0); - if (ret == 1) { + + if (id == 1) { printf("No host cable detected: "); return -ENODEV; } - sunxi_usb_phy_power_on(0); /* port power on */ + + if (!sunxi_usb_phy_power_is_on(0)) + sunxi_usb_phy_power_on(0); } USBC_ForceVbusValidToHigh(musb->mregs); @@ -236,9 +243,6 @@ static void sunxi_musb_disable(struct musb *musb) if (!enabled) return; - if (is_host_enabled(musb)) - sunxi_usb_phy_power_off(0); /* port power off */ - USBC_ForceVbusValidToLow(musb->mregs); mdelay(200); /* Wait for the current session to timeout */ -- 2.4.3
