2021-04-13i2c: mpc: Remove redundant NULL checkChris Packham
In mpc_i2c_get_fdr_8xxx div is assigned as we iterate through the mpc_i2c_dividers_8xxx array. By the time we exit the loop div will either have the value that matches the requested speed or be pointing at the last entry in mpc_i2c_dividers_8xxx. Checking for div being NULL after the loop is redundant so remove the check.

2021-04-05i2c: designware: Add driver support for AMD NAVI GPUSanket Goswami
The Latest AMD NAVI GPU card has an integrated Type-C controller and Designware I2C with PCI Interface. The PD controller for USB Type-C can be accessed over I2C. The client driver is part of the USB Type-C UCSI driver. Also, there exists a couple of notable IP limitations that are dealt as workarounds: - I2C transaction work on a polling mode as IP does not generate interrupt. - I2C read command sent twice to address the IP issues. - AMD NAVI GPU based products are already in the commercial market, hence some of the I2C parameters are statically programmed as they can not be part of the ACPI table.

https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus ASoC: Updates for v5.12 Another quiet release in terms of features, though several of the drivers got quite a bit of work and there were a lot of general changes resulting from Morimoto-san's ongoing cleanup work. - As ever, lots of hard work by Morimoto-san cleaning up the code and making it more consistent. - Many improvements in the Intel drivers including a wide range of quirks and bug fixes. - A KUnit testsuite for the topology code. - Support for Ingenic JZ4760(B), Intel AlderLake-P, DT configured nVidia cards, Qualcomm lpass-rx-macro and lpass-tx-macro - Removal of obsolete SIRF prima/atlas, Txx9 and ZTE zx drivers.
2021-02-12i2c: remove redundant error print in stm32f7_i2c_probeMenglong Dong
Coccinelle reports a redundant error print in stm32f7_i2c_probe. As 'platform_get_irq' already prints the error message, error print here is redundant and can be removed. Signed-off-by: Menglong Dong <dong.menglong@zte.com.cn> Signed-off-by: Wolfram Sang <wsa@kernel.org>

The digital filter related computation are present in the driver however the programming of the filter within the IP is missing. The maximum value for the DNF is wrong and should be 15 instead of 16.

2021-02-09i2c: mv64xxx: Fix check for missing clock after adding RPMSamuel Holland
In commit e5c02cf54154 ("i2c: mv64xxx: Add runtime PM support"), error pointers to optional clocks were replaced by NULL to simplify the resume callback implementation. However, that commit missed that the IS_ERR check in mv64xxx_of_config should be replaced with a NULL check. As a result, the check always passes, even for an invalid device tree.

2021-02-02amba: Make the remove callback return voidUwe Kleine-König
All amba drivers return 0 in their remove callback. Together with the driver core ignoring the return value anyhow, it doesn't make sense to return a value here. Change the remove prototype to return void, which makes it explicit that returning an error value doesn't work as expected. This simplifies changing the core remove callback to return void, too.

2021-02-01i2c: imx: Synthesize end of transaction events without idle interruptsKevin Paul Herbert
Only the Layerscape SoCs have interrupts on bus idle, which facilitate sending events which complete slave bus transactions. Add support for synthesizing missing events. If we see a master request, or a newly addressed slave request, if the last event sent to the backend was I2C_SLAVE_READ_REQUESTED, send the backend a I2C_SLAVE_READ_PROCESSED followed by I2C_SLAVE_STOP. For all other events, send an I2C_SLAVE_STOP.
