| | * mfd: omap-usb-tll: Add OMAP5 revision and HSIC supportRoger Quadros2013-02-13
| | | | | | | | | | | | | | | | | | | | | | | | The TLL module on OMAP5 has 3 channels. HSIC mode requires the TLL channel to be in Transparent UTMI mode. Signed-off-by: Roger Quadros <rogerq@ti.com> Reviewed-by: Felipe Balbi <balbi@ti.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | omap_enable/disable_tll() can fail if TLL device is not initialized. It could be due to multiple reasons and not only due to missing platform data. Also make local variables static and use 'struct device *' instead of 'struct platform_device *' for global reference.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Every channel has a functional clock that is similarly named. It makes sense to use a for loop to manage these clocks as OMAPs can come with up to 3 channels. Dynamically allocate and get channel clocks depending on the number of clocks avaiable on the platform.

| * | mfd: lpc_sch: Accomodate partial population of the MFD devicesDarren Hart2013-02-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current probe aborts if any of the 3 base address registers are disabled. On a TunnelCreek system I am working on, this resulted in the SMBIOS and GPIO devices being removed when it couldn't read the base address for the watchdog timer. This patch accommodates partial population of the lpc_sch_cells array and only aborts if all the base address registers are disabled. A max size array is allocated and the individual device cells are added to it after their base addresses are successfully determined. This simplifies the code a bit by removing the need for the separate tunnelcreek cells array and combining some of the add/remove logic.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 8a6aaa3 (mfd: twl-core: Collect global variables behind one private structure (global)) removed the variable "inuse" that is used to determine if the device has been initialised and now use the twl_priv structure instead. This is causing the kernel to panic on OMAP3+ devices using the twl driver, because we try to access the twl_priv->ready member before checking if twl_priv is initialised. Fix this and move this test to the beginning of the twl_i2c_read/write function because twl_get_last_module() also uses the twl_priv structure.

In order for us to do that, the trigger needs to be set in the associated flags. However, unless a irq_set_type() function pointer is passed when registering the IRQ chip, the IRQ subsystem will refuse to do it. For that reason, we're providing one.

However the bit mask for hwirqs 43 and 44 was shifting the bit mask incorrectly, resulting in the wrong IRQ being mased/unmasked. Further while the patch would mask/unmask the correct line, when the interrupt actually came in, it would still be treated as a valid hwirq. The offsetting applied when masking/unmasking was not applied when handling the IRQ, i.e. the falling edge lines were not routed back to the rising edge lines. This fixes both cases. The end result has been tested with the SIM detect IRQ, GPIO12, hwirq 46 and 62.

| | |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In an upcoming patch, the gpio-ab8500 driver will relinquish all IRQ handling capability and pass it back into the AB8500 core driver. This will aid in reducing massive code duplication within the kernel. Also, most of the functionality is already in the AB8500 core driver, as the GPIO IRQs are actually sandwiched between lots of other IRQs which the core driver already handles. All we're doing here is providing the core driver with knowledge that each GPIO has two IRQs assigned to it; one for rising and a separate one for falling.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Realtek card reader supports both SD and MS card. According to the settings of rtsx MFD driver, SD host will be probed before MS host. If we boot/reboot Linux with SD card inserted, the resetting flow of SD card will succeed, and the following resetting flow of MS is sure to fail. Then MS upper-level driver will ask rtsx driver to turn power off. This request leads to the result that the following SD commands fail and SD card can't be accessed again. In this commit, Realtek's SD and MS host driver will check whether the card that upper driver requesting is the one existing in the slot. If not, Realtek's host driver will refuse the operation to make sure the exlusive accessing at the same time.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | The resolution of msleep is related to HZ, so with HZ set to 100 any msleep of less than 10ms will become ~10ms. Signed-off-by: Lee Jones <lee.jones@linaro.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It's possible to supply a string to provide a reason for triggering a restart. In this case our reason is to enter charging-only mode, as a charger was found to be present.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a charger is connected, we usually want AB8500 based systems to reboot into charging-only mode. However, if the battery type cannot be identified this would be futile, so we'll just shut the system down instead.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The kernel allows us to specify a function call-back which will be invoked when a system power-off request has been received.
