2012-11-26mfd: Simplify IRQ domain registration code in STMPELee Jones1-9/+5
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.

2012-11-23Documentation: Fix historical inconsistency in STMPE DT docLee Jones1-2/+2
Previously a generic binding 'i2c-client-wake' was created which enabled I2C devices to register themselves as wake-up devices. This binding was later over-thrown by 'wakeup-source'. The STMPE driver was fixed-up, but the document was neglected. This patch aims to rectify that.

At every boot of an (outdated) laptop lpc_ich prints an error: lpc_ich 0000:00:1f.0: I/O space for GPIO uninitialized But if one looks at lpc_ich's probe function one notices that the code only cares if both lpc_ich_init_wdt() and lpc_ich_init_gpio() fail to add any cells.

The older southbridges supported by the lpc_ich driver do not provide memory-mapped space of the root complex. The driver correctly avoids computing the iomem address in this case, yet submits a zeroed resource request anyway (via mfd_add_devices()).

2012-11-21mmc: rtsx: Configure SD_CFG2 register in sd_rw_multiWei WANG1-0/+1
For Realtek card reader, internal regsiter SD_CFG2 should be configured before transferring data. The default value of SD_CFG2 is proper for writing data. But for reading sequence, the timing is not good enough. So in some extreme circumstance, card reader may sample the response data from the card as good even if the data is wrong. And this will cause the bad consequence. In the prior version, the value of this register has been calculated, but forgotten to write back to the internal register.
