2014-08-14drivers/mfd/rtsx_usb.c: export device tableJeff Mahoney
The rtsx_usb driver contains the table for the devices it supports but doesn't export it. As a result, no alias is generated and it doesn't get loaded automatically.

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull timer and time updates from Thomas Gleixner: "A rather large update of timers, timekeeping & co - Core timekeeping code is year-2038 safe now for 32bit machines. Now we just need to fix all in kernel users and the gazillion of user space interfaces which rely on timespec/timeval :) - Better cache layout for the timekeeping internal data structures. - Proper nanosecond based interfaces for in kernel users. - Tree wide cleanup of code which wants nanoseconds but does hoops and loops to convert back and forth from timespecs. Some of it definitely belongs into the ugly code museum. - Consolidation of the timekeeping interface zoo. - A fast NMI safe accessor to clock monotonic for tracing. This is a long standing request to support correlated user/kernel space traces. With proper NTP frequency correction it's also suitable for correlation of traces accross separate machines. - Checkpoint/restart support for timerfd. - A few NOHZ[_FULL] improvements in the [hr]timer code. - Code move from kernel to kernel/time of all time* related code. - New clocksource/event drivers from the ARM universe. I'm really impressed that despite an architected timer in the newer chips SoC manufacturers insist on inventing new and differently broken SoC specific timers. [ Ed. "Impressed"? I don't think that word means what you think it means ] - Another round of code move from arch to drivers.

2014-07-29mfd: omap-usb-host: Fix improper mask use.Michael Welling
single-ulpi-bypass is a flag used for older OMAP3 silicon. The flag when set, can excite code that improperly uses the OMAP_UHH_HOSTCONFIG_UPLI_BYPASS define to clear the corresponding bit. Instead it clears all of the other bits disabling all of the ports in the process.

2014-07-28mfd: arizona: Only free the CTRLIF_ERR IRQ if we requested itCharles Keepax
We only request the control interface error IRQ if we set ctrlif_error, as such we should only free it in that situation. Otherwise we will attempt to free an IRQ we never requested and get a warning from the IRQ core. This patch moves the ctrlif_error variable into the arizona structure and checks it in all cases we free the control interface error IRQ.

2014-07-21mfd: sun6i-prcm: Add support for Allwinner A23 PRCMChen-Yu Tsai
The Allwinner A23 SoC has a PRCM unit like the previous A31 SoC. The differences are the AR100 clock can no longer be modified, the APB0 clock has different divisors, and some clock gates are gone. This patch adds a compatible with a modified subdevice list for the A23.

2014-07-09mfd: cros_ec: Use the proper size when looking at the cros_ec_i2c resultDoug Anderson
We know how many bytes the EC should be sending us (which is also the number of bytes transferred) and also how many bytes the EC actually wanted to send to us. When computing the checksum and copying back data let's make sure we take the lesser of the two of those. We'll also complain if the EC tried to send us too many bytes. The EC sending us too few bytes is legit for when we send the EC an invalid command. This is based on similar code in cros_ec_spi.
