2012-09-21ARM: dts: Specify address and size cells for i2c controllers for EXYNOS4Tomasz Figa

2012-09-21ARM: dts: Assume status of all optional nodes as disabled for exynos4Tomasz Figa
Currently all boards must explicitly disable all unused device tree nodes of unused components (e.g. i2c, sdhci, etc...). This makes it necessary to all boards to be aware of all components on the SoC, which in turns makes board dts files longer and more difficult to maintain (e.g. adding new components to SoC-level tree requires adding nodes with status="disabled" to every board). This patch changes "status" of all optional components in SoC-level dts file to "disabled", adds status="okay" to respective nodes of used components in dts of all boards and removes all nodes with only status="disabled" from boards dts.

Most definitions from exynos4210.dtsi can be applied for other SoCs from EXYNOS4 line as well, so move the common part into separate file that can be included by dtsi files of other EXYNOS4 SoCs (as well as current exynos4210.dtsi).

2012-09-20lp8727_charger: Clean up lp8727 definitionsKim, Milo

2012-09-20lp8727_charger: Fix code for getting battery tempKim, Milo
For better understanding, use specific function and definitions rather than magic numbers. New enum type for die temperature is matched with hex codes.

2012-09-20lp8727_charger: Clean up the interrupt handlerKim, Milo
For better understanding, function name is changed. (lp8727_intr_config() is replaced with lp8727_setup_irq().) The private IRQ number is set when the IRQ is allocated successfully. This data is used for releasing the IRQ on unloading the driver. Even the IRQ number is not defined, the driver should be operated. In this case, just return as 0. In additional function lp8727_release_irq(), the workqueue is canceled and the allocated IRQ is released.

2012-09-20lp8727_charger: Remove unnecessary workqueue threadKim, Milo
LP8727 has two IRQ threads. One is the I2C HW IRQ pin, the other is for delayed interrupt processing. But this delayed processing can be handled without additional single thread by using schedule_delayed_work() with jiffies time value.

2012-09-20lp8727_charger: Add configurable debouce timerKim, Milo
Debounce time is configurable in the platform side. If it is not defined, the default value is 270ms. Platform data is msec unit, and this time is converted to jiffies internally. The workqueue uses this jiffies time in the interrupt handling. So debounce_jiffies is added in the private data.

2012-09-20lp8727_charger: Fix buggy code of NULL pdataKim, Milo
LP8727 platform data is optional, so the driver should work even the platform data is NULL. To check the platform data, charging parameter data should be changed to the pointer type. Fix NULL point access problem when getting the battery properties. When the data is NULL, just return as invalid value.

2012-09-20lp8727_charger: Cleanup _probe() and _remove()Kim, Milo
If the lp8727_register_psy() gets failed, registered interrupt handler should be freed, but this is not complete solution. It has still problem. Assume that the IRQ occurs while unregistering power supply devices. Then the ISR will access to freed IRQ. From Anton's opinion, it can be resolved if re-ordering the call sequence. Register power supplies first, then create interrupt handler. Then no need to free the IRQ in _probe(). Additionally goto statements can be removed because those can be replaced with return statements. The _remove() should be changed the sequence - in reverse order of _probe() Signed-off-by: Milo(Woogyom) Kim <milo.kim@ti.com> Signed-off-by: Anton Vorontsov <anton.vorontsov@linaro.org>

2012-09-20Revert "PCI: Use hotplug-safe pci_get_domain_bus_and_slot()"Bjorn Helgaas
This reverts commit 433efd2247b0cbf5e7e86275e1f21281d3b99047. When we remove an SR-IOV device, we have this call chain: driver .remove() method pci_disable_sriov() sriov_disable() virtfn_remove() pci_get_domain_bus_and_slot() sriov_disable() is only called for PFs, not for VFs. When it's called for a PF, it loops through all the VFs and calls virtfn_remove() for each. But we stop and remove VFs before PFs, so by the time we get to virtfn_remove(), the VFs have already been stopped and deleted from the device list. Now pci_get_domain_bus_and_slot(), which uses bus_find_device() and relies on that device list, doesn't find the VFs, so the VF references aren't released correctly.
