2019-09-02mfd: db8500-prcmu: Support the higher DB8520 ARMSSLinus Walleij
The DB8520 used in a lot of Samsung phones has a slightly higher maximum ARMSS frequency than the DB8500. In order to not confuse the OPP framework and cpufreq, make sure the PRCMU driver returns the correct frequency.

2019-09-02mfd: intel-lpss: Use MODULE_SOFTDEP() instead of implicit requestAndy Shevchenko
There is no need to handle optional module request in the driver when user space tools has that feature for ages.

2019-09-02mfd: Add support for Merrifield Basin Cove PMICAndy Shevchenko
Add an MFD driver for Intel Merrifield Basin Cove PMIC. Firmware on the platforms which are using Basin Cove PMIC is "smarter" than on the rest supported by vanilla kernel. It handles first level of interrupt itself, while others do it on OS level. The driver is done in the same way as the rest of Intel PMIC MFD drivers in the kernel to support the initial design. The design allows to use one driver among few PMICs without knowing implementation details of the each hardware version or generation.

2019-08-12mfd: intel-lpss: Remove D3cold delayKai-Heng Feng
Goodix touchpad may drop its first couple input events when i2c-designware-platdrv and intel-lpss it connects to took too long to runtime resume from runtime suspended state. This issue happens becuase the touchpad has a rather small buffer to store up to 13 input events, so if the host doesn't read those events in time (i.e. runtime resume takes too long), events are dropped from the touchpad's buffer. The bottleneck is D3cold delay it waits when transitioning from D3cold to D0, hence remove the delay to make the resume faster. I've tested some systems with intel-lpss and haven't seen any regression.

2019-08-08mfd/syscon: Add device_node_to_regmap()Paul Cercueil
device_node_to_regmap() is exactly like syscon_node_to_regmap(), but it does not check that the node is compatible with "syscon", and won't attach the first clock it finds to the regmap. The rationale behind this, is that one device node with a standard compatible string "foo,bar" can be covered by multiple drivers sharing a regmap, or by a single driver doing all the job without a regmap, but these are implementation details which shouldn't reflect on the devicetree.

2019-07-25mfd: max77620: Add of_node_put() before returnNishka Dasgupta
Each iteration of for_each_child_of_node puts the previous node, but in the case of a return from the middle of the loop, there is no put, thus causing a memory leak. Hence add an of_node_put before the return. Issue found with Coccinelle. Signed-off-by: Nishka Dasgupta <nishkadg.linux@gmail.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>
