2016-11-26mfd: stmpe: Fix RESET regression on STMPE2401Linus Walleij
commit f40584200bc4af7aa4399635b9ac213c62a13ae7 upstream. Since commit c4dd1ba355aae2bc3d1213da6c66c53e3c31e028 ("mfd: stmpe: Add reset support for all STMPE variant") we're resetting the STMPE expanders before use. This caused a regression on the STMP2401 on the Nomadik NHK8815: stmpe-i2c 0-0043: stmpe2401 detected, chip id: 0x101 nmk-i2c 101f8000.i2c0: write to slave 0x43 timed out nmk-i2c 101f8000.i2c0: no ack received after address transmission stmpe-i2c 0-0044: stmpe2401 detected, chip id: 0x101 nmk-i2c 101f8000.i2c0: write to slave 0x44 timed out nmk-i2c 101f8000.i2c0: no ack received after address transmission It turns out that we start to poll for the reset bit to go low again too quickly: the STMPE2401 is not yet online and ready to be asked for the status of the RESET bit. By introducing a 10ms delay before starting to hammer the register for information, we get back to normal: stmpe-i2c 0-0043: stmpe2401 detected, chip id: 0x101 stmpe-i2c 0-0044: stmpe2401 detected, chip id: 0x101 Cc: Amelie Delaunay <amelie.delaunay@st.com> Fixes: c4dd1ba355aa ("mfd: stmpe: Add reset support for all STMPE variant") Signed-off-by: Linus Walleij <linus.walleij@linaro.org> Acked-by: Patrice Chotard <patrice.chotard@st.com> Signed-off-by: Lee Jones <lee.jones@linaro.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

commit 274e43edcda6f709aa67e436b3123e45a6270923 upstream. Commit 41a3da2b8e163 ("mfd: intel-lpss: Save register context on suspend") saved the register context while going to suspend and also put the device in reset state. Due to the resetting of device, system cannot enter S3/S0ix states when no_console_suspend flag is enabled. The system and serial console both hang. The resetting of device is not needed while going to suspend. Hence remove this code.

commit 8dcc5ff8fcaf778bb57ab4448fedca9e381d088f upstream. Member "status" of struct usb_sg_request is managed by usb core. A spin lock is used to serialize the change of it. The driver could check the value of req->status, but should avoid changing it without the hold of the spinlock. Otherwise, it could cause race or error in usb core. This patch could be backported to stable kernels with version later than v3.14.

2016-06-30mfd: max77620: Fix FPS switch statementsRhyland Klein
When configuring FPS during probe, assuming a DT node is present for FPS, the code can run into a problem with the switch statements in max77620_config_fps() and max77620_get_fps_period_reg_value(). Namely, in the case of chip->chip_id == MAX77620, it will set fps_[mix|max]_period but then fall through to the default switch case and return -EINVAL. Returning this from max77620_config_fps() will cause probe to fail.

2016-06-29mfd: qcom_rpm: Parametrize also ack selector sizeLinus Walleij
The RPM has two sets of selectors (IPC bit fields): request and acknowledge. Apparently, some models use 4*32 bit words for select and some use 7*32 bit words for request, but all use 7*32 words for acknowledge bits. So apparently you can on the models with requests of 4*32 select bits send 4*32 messages and get 7*32 different replies, so on ACK interrupt, 7*32 bit words need to be read. This is how the vendor code apparently works.

2016-06-29mfd: qcom_rpm: Fix offset error for msm8660Linus Walleij
The RPM in MSM8660/APQ8060 has different offsets to the selector ACK and request context ACK registers. Make all these register offsets part of the per-SoC data and assign the right values. The bug was found by verifying backwards to the vendor tree in the out-of-tree files <mach/rpm-[8660|8064|8960]>: all were using offsets 3,11,15,23 and a select size of 4, except the MSM8660/APQ8060 which was using offsets 3,11,19,27 and a select size of 7. All other platforms apart from msm8660 were affected by reading excess registers, since 7 was hardcoded as the number of select words, this patch makes also this part dynamic so we only write/read as many select words as the platform actually use. Symptoms of this bug when using msm8660: the first RPM transaction would work, but the next would stall or raise an error since the previous transaction was not properly ACKed as the ACK words were read at the wrong offset.

The kernel expects the power_off function to not return, and if it does it panics. Add a slight delay after the i2c write which turns off power through the PMIC, to give capacitors etc. some time to drain. Without this the kernel lives on long enough after the poweroff to print the following on the serial console on my Mele A1000G quad: [ 248.583588] reboot: Power down [ 248.600490] Kernel pa With the delay the start of printing "Kernel panic" is gone.

2016-06-29mfd: max8925-i2c: Make it explicitly non-modularPaul Gortmaker
The Kconfig currently controlling compilation of this code is: drivers/mfd/Kconfig: config MFD_MAX8925 drivers/mfd/Kconfig: bool "Maxim Semiconductor MAX8925 PMIC Support" ...meaning that it currently is not being built as a module by anyone. Lets remove the modular code that is essentially orphaned, so that when reading the driver there is no doubt it is builtin-only. Since module_init was not in use by this code, the init ordering remains unchanged with this commit. Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code. We also delete the MODULE_LICENSE tag etc. since all that information is already contained at the top of the file in the comments.
