phy: miphy365x: Fix off-by-one error

2014-09-12T06:05:31Z

We index the RX/TX speed select values in the following way: rx_tx_spd[miphy_phy->sata_gen]; However rx_tx_spd[] starts at index zero and the SATA_GENx's start at one. In this patch we pad out the first element in rx_tx_spd[] in an attempt to realign the values.

phy: miphy365x: Select GENERIC_PHY instead of depending on it

2014-08-28T05:47:43Z

Enabling GENERIC_PHY in the shared (by most ARM sub-architectures) defconfig multi_v7_defconfig is prohibited. Instead, we'll enable it from the Kconfig whenever PHY_MIPHY365X is enabled. Cc: Kishon Vijay Abraham I Signed-off-by: Lee Jones Signed-off-by: Kishon Vijay Abraham I

phy: exynos5-usbdrd: Add MODULE_DEVICE_TABLE entry

2014-08-28T05:47:43Z

Add a MODULE_DEVICE_TABLE call for OF match tables. This allows the module to be autoloaded based on devicetree information. Signed-off-by: Sjoerd Simons Signed-off-by: Kishon Vijay Abraham I

usb: phy: twl4030-usb: Fix lost interrupts after ID pin goes down

2014-08-24T12:17:54Z

Commit 249751f22380 ("usb: phy: twl4030-usb: poll for ID disconnect") added twl4030_id_workaround_work() to deal with lost interrupts after ID pin goes down. Looks like commit f1ddc24c9e33 ("usb: phy: twl4030-usb: remove *set_suspend* and *phy_init* ops") changed things around for the generic phy framework, and delayed work no longer got called except initially during boot. The PHY connect and disconnect interrupts for twl4030-usb are not working after disconnecting a USB-A cable from the board, and the deeper idle states for omap are blocked as the USB controller stays busy. The issue can be solved by calling delayed work from twl4030_usb_irq() when ID pin is down and the PHY is not asleep like we already do in twl4030_id_workaround_work(). But as both twl4030_usb_irq() and twl4030_id_workaround_work() already do pretty much the same thing, let's call twl4030_usb_irq() from twl4030_id_workaround_work() instead of adding some more duplicate code. We also must call sysfs_notify() only when we have an interrupt and not from the delayed work as notified by Grazvydas Ignotas .

usb: phy: twl4030-usb: Fix regressions to runtime PM on omaps

2014-08-24T12:17:53Z

Commit 30a70b026b4cd ("usb: musb: fix obex in g_nokia.ko causing kernel panic") attempted to fix runtime PM handling for PHYs that are on the I2C bus. Commit 3063a12be2b0 ("usb: musb: fix PHY power on/off") then changed things around to enable of PHYs that rely on runtime PM. These changes however broke idling of the PHY and causes at least 100 mW extra power consumption on omaps, which is a lot with the idle power consumption being below 10 mW range on many devices. As calling phy_power_on/off from runtime PM calls in the USB causes complicated issues with I2C connected PHYs, let's just let the PHY do it's own runtime PM as needed. This leaves out the dependency between PHYs and USB controller drivers for runtime PM. Let's fix the regression for twl4030-usb by adding minimal runtime PM support. This allows idling the PHY on disconnect. Note that we are changing to use standard runtime PM handling for twl4030_phy_init() as that function just checks the state and does not initialize the PHY. The PHY won't get initialized until in twl4030_phy_power_on().

Pull ARM SoC driver changes from Olof Johansson: "A handful of driver-related changes. We've had a bunch of them going in through other branches as well, so it's only a part of what we really have this release. Larger pieces are: - Removal of a now unused PWM driver for atmel [ This includes AVR32 changes that have been appropriately acked ] - Performance counter support for the arm CCN interconnect - OMAP mailbox driver cleanups and consolidation - PCI and SATA PHY drivers for SPEAr 13xx platforms - Redefinition (with backwards compatibility!) of PCI DT bindings for Tegra to better model regulators/power" Note: this merge also fixes up the semantic conflict with the new calling convention for devm_phy_create(), see commit f0ed817638b5 ("phy: core: Let node ptr of PHY point to PHY and not of PHY provider") that came in through Greg's USB tree.

phy: miphy365x: Represent each PHY channel as a DT subnode

This has the added advantages of being able to enable/disable each of the channels as simply as enabling/disabling the DT node. Suggested-by: Kishon Vijay Abraham I Signed-off-by: Lee Jones Signed-off-by: Kishon Vijay Abraham I
