2021-04-06i2c: designware: Add driver support for AMD NAVI GPUSanket Goswami4-0/+205
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 Dong1-5/+1
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>
2021-02-12i2c: stm32f7: fix configuration of the digital filterAlain Volmat1-1/+10
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.

2021-02-12i2c: testunit: add support for block process callsWolfram Sang1-2/+10
Devices offering SMBus block process calls are rare, so add it to the testunit. This is also a good test case for testing proper I2C_M_RECV_LEN flag handling of I2C bus masters emulating SMBus.

2021-02-09i2c: mv64xxx: Fix check for missing clock after adding RPMSamuel Holland1-1/+1
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.

2021-02-09i2c: mux: mlxcpld: Add callback to notify mux creation completionVadim Pasternak1-0/+4
Add notification to inform caller that mux objects array has been created. It allows to user, invoked platform device registration for "i2c-mux-mlxcpld" driver, to be notified that mux infrastructure is available, and thus some devices could be connected to this infrastructure.

2021-02-09i2c: mux: mlxcpld: Extend supported mux numberVadim Pasternak1-8/+2
Allow to extend mux number supported by driver. Currently it is limited by eight, which is not enough for new coming Mellanox modular system with line cards, which require up to 64 mux support.

2021-02-09i2c: mux: mlxcpld: Get rid of adapter numbers enforcementVadim Pasternak1-5/+2
Do not set the argument 'force_nr' of i2c_mux_add_adapter() routine, instead provide argument 'chan_id'. Rename mux ids array from 'adap_ids' to 'chan_ids'. The motivation is to prepare infrastructure to be able to: - Create only the child adapters which are actually needed - for which channel ids are specified. - To assign 'nrs' to these child adapters dynamically, with no 'nr' enforcement.
