Add the version of the EC in the Tolino Shine 2 HD to the supported versions. It seems not to have an RTC and does not ack data written to it. The vendor kernel happily ignores write errors, using I2C via userspace i2c-set also shows the error. So add a quirk to ignore that error. PWM can be successfully configured despite of that error.

2021-04-14mfd: da9063: Support SMBus and I2C modeHubert Streidl
By default the PMIC DA9063 2-wire interface is SMBus compliant. This means the PMIC will automatically reset the interface when the clock signal ceases for more than the SMBus timeout of 35 ms. If the I2C driver / device is not capable of creating atomic I2C transactions, a context change can cause a ceasing of the clock signal. This can happen if for example a real-time thread is scheduled. Then the DA9063 in SMBus mode will reset the 2-wire interface. Subsequently a write message could end up in the wrong register. This could cause unpredictable system behavior. The DA9063 PMIC also supports an I2C compliant mode for the 2-wire interface. This mode does not reset the interface when the clock signal ceases. Thus the problem depicted above does not occur. This patch tests for the bus functionality "I2C_FUNC_I2C". It can reasonably be assumed that the bus cannot obey SMBus timings if this functionality is set. SMBus commands most probably are emulated in this case which is prone to the latency issue described above. This patch enables the I2C bus mode if I2C_FUNC_I2C is set or otherwise keeps the default SMBus mode.

2021-03-10mfd: bd9576: Add IRQ supportMatti Vaittinen
BD9573 and BD9576 support set of "protection" interrupts for "fatal" issues. Those lead to SOC reset as PMIC shuts the power outputs. Thus there is no relevant IRQ handling for them. Few "detection" interrupts were added to the BD9576 with the idea that SOC could take some recovery-action before error gets unrecoverable. Unfortunately the BD9576 interrupt logic was not re-evaluated. IRQs are not designed to be properly acknowleged - and IRQ line is kept active for whole duration of error condition (in comparison to informing only about state change). For above reason, do not consider missing IRQ as error. Signed-off-by: Matti Vaittinen <matti.vaittinen@fi.rohmeurope.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>

2021-02-12regulator: bd718x7, bd71828, Fix dvs voltage levelsMatti Vaittinen
The ROHM BD718x7 and BD71828 drivers support setting HW state specific voltages from device-tree. This is used also by various in-tree DTS files. These drivers do incorrectly try to compose bit-map using enum values. By a chance this works for first two valid levels having values 1 and 2 - but setting values for the rest of the levels do indicate capability of setting values for first levels as well. Luckily the regulators which support setting values for SUSPEND/LPSR do usually also support setting values for RUN and IDLE too - thus this has not been such a fatal issue. Fix this by defining the old enum values as bits and fixing the parsing code. This allows keeping existing IC specific drivers intact and only slightly changing the rohm-regulator.c Fixes: 21b72156ede8b ("regulator: bd718x7: Split driver to common and bd718x7 specific parts") Signed-off-by: Matti Vaittinen <matti.vaittinen@fi.rohmeurope.com> Acked-by: Lee Jones <lee.jones@linaro.org> Link: https://lore.kernel.org/r/20210212080023.GA880728@localhost.localdomain Signed-off-by: Mark Brown <broonie@kernel.org>
2021-02-09mfd: intel_msic: Remove driver for deprecated platformAndy Shevchenko
Intel Moorestown and Medfield are quite old Intel Atom based 32-bit platforms, which were in limited use in some Android phones, tablets and consumer electronics more than eight years ago. There are no bugs or problems ever reported outside from Intel for breaking any of that platforms for years. It seems no real users exists who run more or less fresh kernel on it. Commit 05f4434bc130 ("ASoC: Intel: remove mfld_machine") is also in align with this theory. Due to above and to reduce a burden of supporting outdated drivers, remove the support for outdated platforms completely.

2021-02-08mfd: iqs62x: Do not poll during ATIJeff LaBundy
After loading firmware, the driver triggers ATI (calibration) with the newly loaded register configuration in place. Next, the driver polls a register field to ensure ATI completed in a timely fashion and that the device is ready to sense. However, communicating with the device over I2C while ATI is under- way may induce noise in the device and cause ATI to fail. As such, the vendor recommends not to poll the device during ATI. To solve this problem, let the device naturally signal to the host that ATI is complete by way of an interrupt. A completion prevents the sub-devices from being registered until this happens. The former logic that scaled ATI timeout and filter settling delay is not carried forward with the new implementation, as it produces overly conservative delays at lower clock rates. Instead, a single pair of delays that covers all cases is used. Signed-off-by: Jeff LaBundy <jeff@labundy.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>

2021-01-26staging: hikey9xx: hi6421v600-regulator: fix delay logicMauro Carvalho Chehab
The original driver, which can be seen at commit 42f24d9d446a ("staging: regulator: add a regulator driver for HiSilicon 6421v600 SPMI PMIC") had a complex logic to ensure that there won't be multiple power enable/disable commands running at the same time. At the original logic, it were ensured that: - a next power up/down would wait for at least the on/off period; - an extra delay would be granted. It turns that such extra delay has a value of zero, but it was relying on gettimeofday() call, which can take some time. This was later simplified, but there are still some possible issues. In order to avoid that, let's simply add a delay to wait for the power up line to stabilize after powering up a device.

2021-01-15mfd/bus: sunxi-rsb: Make .remove() callback return voidUwe Kleine-König
The driver core ignores the return value of struct device_driver::remove because there is only little that can be done. To simplify the quest to make this function return void, let struct sunxi_rsb_driver::remove return void, too. All users already unconditionally return 0, this commit makes this obvious and ensures future users don't behave differently. To simplify even further, make axp20x_device_remove() return void instead of returning 0 unconditionally, too.
