| | | | | | | | | | | | | | | | | | | | If rtsx_pci_sdmmc is not probed, function pointer pcr->slots[].card_event will point to NULL, and thus rtsx_pci_card_detect will reference a NULL pointer.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the twl4030_write_script function gets called with a zero length argument, its return value does not get set. We know that all scripts have a nonzero length, but returning an error in case they ever do is probably appropriate. Without this patch, building omap2plus_defconfig results in: drivers/mfd/twl4030-power.c: In function 'load_twl4030_script': drivers/mfd/twl4030-power.c:414:5: error: 'err' may be used uninitialized in this function Signed-off-by: Arnd Bergmann <arnd@arndb.de> Reviewed-by: Peter Ujfalusi <peter.ujfalusi@ti.com> Reviewed-by: Amit Kucheria <amit.kucheria@linaro.org> Cc: Kevin Hilman <khilman@deeprootsystems.com> Cc: "Kristo, Tero" <t-kristo@ti.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
| * mfd: da9052/53 lockup fixAshish Jangam2013-01-271-0/+61
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | An issue has been reported where the PMIC either locks up or fails to respond following a system Reset. This could result in a second write in which the bus writes the current content of the write buffer to address of the last I2C access. The failure case is where this unwanted write transfers incorrect data to a critical register. This patch fixes this issue to by following any read or write with a dummy read to a safe register address. A safe register address is one where the contents will not affect the operation of the system.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes a regression in the TC3589x driver introduced in commit 15e27b1088245a2de3b7d09d39cd209212eb16af "mfd: Provide the tc3589x with its own IRQ domain" If a system with a TC3589x expander is booted and a base IRQ is passed from platform data, a legacy domain will be used. However, since the Ux500 is now switched to use SPARSE_IRQ, no descriptors get allocated on-the-fly, and we get a crash. Fix this by switching to using the simple irqdomain that will handle this uniformly and also allocates descriptors explicitly. Also fix two small whitespace errors in the vicinity while we're at it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes two issues with the DB8500 PRCMU irqdomain: - You have to state the irq base 0 to get a linear domain for the DT case from irq_domain_add_simple() - The irqdomain was not used to translate the initial irq request using irq_create_mapping() making the linear case fail as it was lacking a proper descriptor. I took this opportunity to fix two lines of whitespace errors in related code as I was anyway messing around with it.

Then the rest is mostly tiny cleanups and fixes, among which we have Mark's wm5xxx and wm8xxx patchset." Far amount of annoying but largely trivial conflicts.

This work is done in the regmap irq thread - using 'ack_base' register. The ACK registers should be fixed as status register, not mask registers. This patch fixes the infinite interrupt event problem by clearing interrupt status registers. Tested on the AM3517 Craneboard.

But, nobody is actually using it in kernel till now. Also, this is not something part of hardware specs, but is included to cater some board mistakes or quirks. So, better get rid of it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Historically, a driver would have to decide whether it required a Linear or Legacy IRQ domain when registering one. This can end up as quite a lot of code. A new Simple call now exists which simplifies this process. Let's make use of it here.
