Pull i2c updates from Wolfram Sang: "I2C has quite some patches for you this time. I hope it is the move to per-driver-maintainers which is now showing results. We will see. The big news is two new drivers (Nuvoton NPCM and Qualcomm CCI), larger refactoring of the Designware, Tegra, and PXA drivers, the Cadence driver supports being a slave now, and there is support to instanciate SPD eeproms for well-known cases (which will be user-visible because the i801 driver supports it), and some devm_platform_ioremap_resource() conversions which blow up the diffstat. Note that I applied the Nuvoton driver quite late, so some minor fixup patches arrived during the merge window. I chose to apply them right away because they were trivial" * 'i2c/for-5.8' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux: (109 commits) i2c: Drop stray comma in MODULE_AUTHOR statements i2c: npcm7xx: npcm_i2caddr[] can be static MAINTAINERS: npcm7xx: Add maintainer for Nuvoton NPCM BMC i2c: npcm7xx: Fix a couple of error codes in probe i2c: icy: Fix build with CONFIG_AMIGA_PCMCIA=n i2c: npcm7xx: Remove unnecessary parentheses i2c: npcm7xx: Add support for slave mode for Nuvoton i2c: npcm7xx: Add Nuvoton NPCM I2C controller driver dt-bindings: i2c: npcm7xx: add NPCM I2C controller i2c: pxa: don't error out if there's no pinctrl i2c: add 'single-master' property to generic bindings i2c: designware: Add Baikal-T1 System I2C support i2c: designware: Move reg-space remapping into a dedicated function i2c: designware: Retrieve quirk flags as early as possible i2c: designware: Convert driver to using regmap API i2c: designware: Discard Cherry Trail model flag i2c: designware: Add Baytrail sem config DW I2C platform dependency i2c: designware: slave: Set DW I2C core module dependency i2c: designware: Use `-y` to build multi-object modules dt-bindings: i2c: dw: Add Baikal-T1 SoC I2C controller ...

i2c: add 'single-master' property to generic bindings

2020-05-30T21:11:56+00:00

It is useful to know if we are the only master on a given bus. Because this is a HW description of the bus, add it to the generic bindings. Signed-off-by: Wolfram Sang Reviewed-by: Rob Herring Signed-off-by: Wolfram Sang

dt-bindings: i2c: dw: Add Baikal-T1 SoC I2C controller

2020-05-30T09:33:32+00:00

Add the "baikal,bt1-sys-i2c" compatible string to the DW I2C binding. Even though the corresponding node is supposed to be a child of the Baikal-T1 System Controller, its reg property is left required for compatibility.

dt-bindings: i2c: Convert DW I2C slave to the DW I2C master example

2020-05-30T09:33:30+00:00

dtc currently doesn't support I2C_OWN_SLAVE_ADDRESS flag set in the i2c "reg" property. If dtc finds an i2c-slave sub-node having an address higher than ten-bits wide it'll print an ugly warning: Warning (i2c_bus_reg): /example-2/i2c@1120000/eeprom@64: I2C bus unit address format error, expected "40000064" Warning (i2c_bus_reg): /example-2/i2c@1120000/eeprom@64:reg: I2C address must be less than 10-bits, got "0x40000064" In order to silence dtc up let's replace the corresponding DT binding example with a normal DW I2C master mode-based one. It's done by clearing the I2C_OWN_SLAVE_ADDRESS bit in the reg property and converting the sub-node to be compatible with normal EEPROM like "atmel,24c02". Just revert this commit when dtc is fixed.

dt-bindings: i2c: Convert DW I2C binding to DT schema

2020-05-30T09:33:27+00:00

Modern device tree bindings are supposed to be created as YAML-files in accordance with dt-schema. This commit replaces Synopsys DW I2C legacy bare text bindings with YAML file. As before the bindings file states that the corresponding dts node is supposed to be compatible either with generic DW I2C controller or with Microsemi Ocelot SoC I2C one, to have registers, interrupts and clocks properties. In addition the node may have clock-frequency, i2c-sda-hold-time-ns, i2c-scl-falling-time-ns and i2c-sda-falling-time-ns optional properties.
