Merge branch 'i2c/for-4.17' of git://git.kernel.org/pub/scm/linux/ker…
…nel/git/wsa/linux Pull i2c updates from Wolfram Sang: -I2C core now reports proper OF style module alias. I'd like to repeat the note from the commit msg here (Thanks, Javier!): NOTE: This patch may break out-of-tree drivers that were relying on this behavior, and only had an I2C device ID table even when the device was registered via OF. There are no remaining drivers in mainline that do this, but out-of-tree drivers have to be fixed and define a proper OF device ID table to have module auto-loading working. - new driver for the SynQuacer I2C controller - major refactoring of the QUP driver - the piix4 driver now uses request_muxed_region which should fix a long standing resource conflict with the sp5100_tco watchdog - a bunch of small core & driver improvements * 'i2c/for-4.17' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux: (53 commits) i2c: add support for Socionext SynQuacer I2C controller dt-bindings: i2c: add binding for Socionext SynQuacer I2C i2c: Update i2c_trace_msg static key to modern api i2c: fix parameter of trace_i2c_result i2c: imx: avoid taking clk_prepare mutex in PM callbacks i2c: imx: use clk notifier for rate changes i2c: make i2c_check_addr_validity() static i2c: rcar: fix mask value of prohibited bit dt-bindings: i2c: document R8A77965 bindings i2c: pca-platform: drop gpio from platform data i2c: pca-platform: use device_property_read_u32 i2c: pca-platform: unconditionally use devm_gpiod_get_optional sh: sh7785lcr: add GPIO lookup table for i2c controller reset i2c: qup: reorganization of driver code to remove polling for qup v2 i2c: qup: reorganization of driver code to remove polling for qup v1 i2c: qup: send NACK for last read sub transfers i2c: qup: fix buffer overflow for multiple msg of maximum xfer len i2c: qup: change completion timeout according to transfer length i2c: qup: use the complete transfer length to choose DMA mode i2c: qup: proper error handling for i2c error in BAM mode ...

Socionext SynQuacer I2C | ||
|
||
Required properties: | ||
- compatible : Must be "socionext,synquacer-i2c" | ||
- reg : Offset and length of the register set for the device | ||
- interrupts : A single interrupt specifier | ||
- #address-cells : Must be <1>; | ||
- #size-cells : Must be <0>; | ||
- clock-names : Must contain "pclk". | ||
- clocks : Must contain an entry for each name in clock-names. | ||
(See the common clock bindings.) | ||
|
||
Optional properties: | ||
- clock-frequency : Desired I2C bus clock frequency in Hz. As only Normal and | ||
Fast modes are supported, possible values are 100000 and | ||
400000. | ||
|
||
Example : | ||
|
||
i2c@51210000 { | ||
compatible = "socionext,synquacer-i2c"; | ||
reg = <0x51210000 0x1000>; | ||
interrupts = <GIC_SPI 165 IRQ_TYPE_LEVEL_HIGH>; | ||
#address-cells = <1>; | ||
#size-cells = <0>; | ||
clock-names = "pclk"; | ||
clocks = <&clk_i2c>; | ||
clock-frequency = <400000>; | ||
}; |
