| | * mfd: Add WM8994 interrupt controller supportMark Brown2010-04-054-6/+353
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The WM8994 has an interrupt controller which supports interrupts for both CODEC and GPIO portions of the chip. Support this using genirq, while allowing for systems that do not have an interrupt hooked up. Wrapper functions are provided for the IRQ request and free to simplify the code in consumer drivers when handling cases where IRQs are not set up.

These spurious RDR events must be ignored by the software. This patch handles and ignores RDR spurious interrupts. The below sequence is required in interrupt handler for handling this errata: 1. If RDR is set to 1, clear RDR 2. Read I2C status register and check for BusBusy bit. If BusBusy bit is set, skip remaining steps. 3. If BusBusy bit is not set, perform read operation on I2C status register. 4. If RDR is set, clear the same. Check RDR again and clear if it sets RDR bit again. 5. Perform I2C Data Read operation N number of times(where N is value read from the register BUFSTAT-RXSTAT bit fields). Note: This errata is not applicable for omap2420 and omap4. It is applicable for: 1. omap2430 2. omap34xx(including omap3630).

| * | | | i2c-omap: add mpu wake up latency constraint in i2cKalle Jokiniemi2010-05-201-4/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While waiting for completion of the i2c transfer, the MPU could hit OFF mode and cause several msecs of delay that made i2c transfers fail more often. The extra delays and subsequent re-trys cause i2c clocks to be active more often. This has also an negative effect on power consumption. Created a mechanism for passing and using the constraint setting function in driver code. The used mpu wake up latency constraints are now set individually per bus, and they are calculated based on clock rate and fifo size. Thanks to Jarkko Nikula, Moiz Sonasath, Paul Walmsley, and Nishanth Menon for tuning out the details of this patch. Updates by Kevin as requested by Tony: - Remove omap_set_i2c_constraint_func() in favor of conditionally adding the flag in omap_i2c_add_bus() in order to keep all the OMAP conditional checking in a single location. - Update set_mpu_wkup_lat prototypes to match OMAP PM layer so OMAP PM function can be used directly in pdata.

On OMAP4, all I2C register address offsets are changed from OMAP1/2/3 I2C. In order to not have #ifdef's at various places in code, as well as to support multi-OMAP build, an array is created to hold the register addresses with it's offset. This patch was submitted, reviewed and acked on mailing list already.

In order to ensure that we do not attempt to start a new transfer before the bus is idle the driver currently inserts a 1ms delay. This is vastly larger than is generally required and has a visible effect on performance under load, such as when bringing up audio CODECs or reading back status information with non-bulk I2C reads. Replace the sleep with a spin on the IIC status register for up to 1ms. This will busy wait but testing on my SMDK6410 system indicates that the overwhelming majority of transactions complete on the first spin, with maximum latencies of less than 10 spins so the absolute overhead of busy waiting should be at worst comprable to msleep(), and the overall system performance is dramatically improved. The main risk is poor interaction with multimaster systems where we may miss the bus going idle before the next transaction. Defend against this by falling back to the original 1ms delay after 20 spins. The overall effect in my testing is an approximately 20% improvement in kernel startup time.

D'oh. Okay, here's v2, should fix that buglet too. This hack was used when the imon driver was using internal key lookup routines, but became dead weight when the driver was converted to use ir-core's key lookup routines. These bits simply didn't get removed, drop 'em now. Pointed out by Dan Carpenter. v2: fix possible attempt to access beyond end of key table array, also pointed out by Dan.

Please can you revert it: > 7a02f549fcc30fe6be0c0024beae9a3db22e1af6 "Staging: cx25821: fix double > unlock in medusa_video_init()" After reviewing the logic at the function, instead of just adding a patch to revert the wrong one, the better is to apply a different logic: add a goto that will always unlock and return the error. This simplifies the code a little bit, and, instead of just return -EINVAL, it will return the error condition reported by the called functions. This patch is folded with another patch from Dan that added one missing goto. Signed-off-by: Dan Carpenter <error27@gmail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

Also, eliminate what appears to be a typo where all of the channel parameters are getting associated with stream zero's properties, which will work if you happen to have a dual stream board with the exact same configuration, but if they differ then the second stream is going to end up with the first stream's configuration.
