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: Remove dev_err() usage after platform_get_irq()Stephen Boyd
We don't need dev_err() messages when platform_get_irq() fails now that platform_get_irq() prints an error message itself when something goes wrong. Let's remove these prints with a simple semantic patch. // <smpl> @@ expression ret; struct platform_device *E; @@ ret = ( platform_get_irq(E, ...) | platform_get_irq_byname(E, ...) ); if ( \( ret < 0 \| ret <= 0 \) ) { ( -if (ret != -EPROBE_DEFER) -{ ... -dev_err(...); -... } | ... -dev_err(...); ) ... } // </smpl> While we're here, remove braces on if statements that only have one statement (manually).

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.
